FYI on a Network Management Tool Catalog:

Tools for Monitoring and Debugging TCP/IP Internets and Interconnected Devices

Status of this Memo

This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited.

Abstract

The goal of this FYI memo is to provide an update to FYI 2, RFC 1147 [1], which provided practical information to site administrators and network managers. New and/or updated tools are listed in this RFC. Additonal descriptions are welcome, and should be sent to: noctools- entries@merit.edu.

Introduction

A static document cannot incorporate references to the latest tools nor recent revisions to the older catalog entries. To provide a more timely and responsive information source, the NOCtools catalog is available on-line via the Internet and Usenet.


news comp.networks.noctools
ftp wuarchive.wustl.edu:/doc/noctools

Because of publication delays and other factors, some of the entries in this catalog may be out of date. The reader is urged to consult the on-line service to obtain the most up-to-date information.

The index provided in this document reflects the current contents of the on-line documentation.

The NOCtools2 Working Group of the Internet Engineering Task Force (IETF) has compiled this revised catalog. Future revisions will be incorporated into the on-line NOCtools catalog. The reader is encouraged to submit new or revised entries for (near-immediate) electronic publication.

The tools described in this catalog are in no way endorsed by the IETF. For the most part, we have neither evaluated the tools in this catalog, nor validated their descriptions. Most of the descriptions of commercial tools have been provided by vendors. Caveat Emptor.

Acknowledgements

This catalog is the result of work on the part of the NOCTools2 Working Group of the User Services Area of the IETF. The following individuals made especially notable contributions: Chris Myers, Darren Kinley, Gary Malkin, Mohamed Ellozy, and Mike Patton.

Current Postings

The current contents of the NOCtools catalog may be retrieved via anonymous FTP from wuarchive.wustl.edu. The entries are stored as individual files in the directory /doc/noctools.

"No-Writeups" Appendix

This section contains references to tools which are known to exist, but which have not been fully cataloged. If anyone wishes to author an entry for one of these tools please contact us at:

noctools-request@merit.edu

Keep in mind that if these or other tools are included in the future, they will be available in the on-line version of the catalog.

Each mention is separated by a < form-feed > for improved readability. If you intend to actually print-out this section of the catalog, then you should probably strip-out the < ff > .

Keywords

This catalog uses "keywords" for terse characterizations of the tools. Keywords are abbreviated attributes of a tool or its use. To allow cross-comparison of tools, uniform keyword definitions have been developed, and are given below. Following the definitions, there is an index of catalog entries by keyword.

Keyword Definitions

The keywords are always listed in a prefined order, sorted first by the general category into which they fall, and then alphabetically. The categories that have been defined for management tool keywords are:

The keywords used to describe the general management area or functional role of a tool are:

Alarm
a reporting/logging tool that can trigger on specific events within a network.

Tool Descriptions

This section is an updated collection of brief descriptions of tools for managing TCP/IP internets. These entries are in alphabetical order, by tool name.

The entries all follow a standard format. Immediately after the NAME of a tool are its associated KEYWORDS. Keywords are terse descriptions of the purposes or attributes of a tool. A more detailed description of a tool's purpose and characteristics is given in the ABSTRACT section. The MECHANISM section describes how a tool works. In CAVEATS, warnings about tool use are given. In BUGS, known bugs or bug-report procedures are given. LIMITATIONS describes the boundaries of a tool's capabilities. HARDWARE REQUIRED and SOFTWARE REQUIRED relate the operational environment a tool needs. Finally, in AVAILABILITY, pointers to vendors, online repositories, or other sources for a tool are given.

Where tool names conflict, the vendor name is used as well. For example, MITRE, and SNMP Research each submitted an updated description of a tool called, "NETMON". These tools were independently developed, are functionally different, and run in different environments. MITRE's tool is listed as "NETMON_MITRE," and the tool from SNMP Research as "NETMON_WINDOWS_SNMP_RESEARCH".

Internet Tool Catalog ChameLAN-100

NAME
ChameLAN 100

KEYWORDS
analyzer, benchmark, debugger, generator, map, reference, status, traffic; bridge, DECnet, ethernet, FDDI, IP, OSI, NFS, ring; eavesdrop, SNMP, X; standalone, UNIX.

ABSTRACT
Tekelec's ChameLAN 100 is a portable diagnostic system for monitoring and simulation of FDDI, Ethernet and Token Ring networks -- simultaneously. Protocol analysis of multiple topologies, as well as mixed topoloies simultaneously, is a key feature of the product family. Tekelec's proprietary FDDI hardware guarantees complete real-time analysis of networks and network components at the full ring bandwidth of 125 Mbps. It passively connects to the network and captures 100 percent of the data, measures performance and isolates real-time problems.

The simulation option offers full bandwidth load generation that allows you to create and simulate any network condition. It gives you the ability to inject errors and misformed frames. A set of confidence tests allow simple evaluation of new equipment. A ring map feature displays network topology and status of all nodes via the SMT process.

Monitoring of FDDI, Ethernet and Token Ring allows the user to: view network status in real time; view network, node, or node pair statistics; capture frames; control capture using trigger and filter capabilities; view real-time statistics; view captured frames in decoded format; and view the last frame transmitted by each station.

The following Real-Time Network Statistics of FDDI, Ethernet and Token Ring networks is displayed: frame rate, runts, byte rate, jabbers, CRC/align errors, and collisions.

Product developers can use the ChameLAN 100 to observe and control various events to help debug their FDDI, Ethernet and Token Ring products. End users can perform real-time monitoring to test and diagnose problems that may occur when developing, installing or managing FDDI, Ethernet and Token Ring networks and network products. End users can use the ChameLAN 100 to aid in the installation and maintenance of Ethernet and Token Ring networks. To isolate specific network trouble spots the ChameLAN 100 uses filtering and triggering techniques for data capture. Higher level protocol decode includes TCP/IP, OSI and DECnet protocol suites. Protocol decode of IPX, SNMP, XTP, and AppleTalk are also supported. Development of additional protocol decodes is also under development. The ChameLAN 100 family also offers a Protocol Management Development System (PMDS) that enables users to develop custom protocol decode suites.

The FDDI, Ethernet and Token Ring hardware interfaces feature independent processing power. Real-time data is monitored unobtrusively at full bandwidth without affecting network activity. Real-time data may also be saved to a 120MB or optional 200MB hard disk drive for later analysis. FDDI data is captured at 125 megabits per second (Mbps), Ethernet at 10 Mbps and Token Ring at 4 or 16 Mbps.

MECHANISM
This portable, standalone unit incorporates the power of UNIX, X-Windows and Motif. Its UNIX-based programming interface facilitates development of customized monitoring and simulation applications. The ChameLAN 100 may connect to the network at any location using standard equipment. Standard graphical Motif/X-Windows and TCP/IP allow remote control through Ethernet and 10Base T interfaces. Tekelec also offers a rackmounted model -- ChameLAN 100-X. Both models can be controlled via a Sun Workstation remotely.

CAVEATS
none.

BUGS
none known.

LIMITATIONS

Internet Tool Catalog DECADDRS

NAME
decaddrs, decaroute, decnroute, xnsroutes, bridgetab

KEYWORDS
manager, map, routing; bridge, DECnet; NMS, SNMP; UNIX.

ABSTRACT
These commands display private MIB information from Wellfleet systems. They retrieve and format for display values of one or several MIB variables from the Wellfleet Communications private enterprise MIB, using the SNMP (RFC1098). In particular these tools are used to examine the non-IP modules (DECnet, XNS, and Bridg ing) of a Wellfleet system.

Decaddrs displays the DECnet configuration of a Wellfleet system acting as a DECnet router, showing the static parameters associated with each DECnet inter face. Decaroute and decnroute display the DECnet inter-area and intra-area routing tables (that is area routes and node routes). Xnsroutes displays routes known to a Wellfleet system acting as an XNS router. Bridgetab displays the bridge forwarding table with the disposition of traffic arriving from or directed to each station known to the Wellfleet bridge module. All these commands take an IP address as the argument and can specify an SNMP community for the retrieval. One SNMP query is performed for each row of the table. Note that the Wellfleet system must be operating as an IP router for the SNMP to be accessible.

MECHANISM
Management information is exchanged by use of SNMP.

CAVEATS

The EMANATE system consists of several logically independent components and subsystems:

Internet Tool Catalog ETHERFIND_SUN

NAME
etherfind

KEYWORDS
traffic; ethernet, IP, NFS; eavesdrop; UNIX.

ABSTRACT
Etherfind examines the packets that traverse a network interface, and outputs a text file describing the traffic. In the file, a single line of text describes a single packet: it contains values such as protocol type, length, source, and destination. Etherfind can print out all packet traffic on the ethernet, or traffic for the local host. Further packet filtering can be done on the basis of protocol: IP, ARP, RARP, ICMP, UDP, ND, TCP, and filtering can also be done based on the source, destination addresses as well as TCP and UDP port numbers.

MECHANISM
In usual operations, and by default, etherfind puts the interface in promiscuous mode. In 4.3BSD UNIX and related OSs, it uses a Network Interface Tap (NIT) to obtain a copy of traffic on an ethernet interface.

CAVEATS
None.

BUGS
None known.

LIMITATIONS
Minimal protocol information is printed. Can only be run by the super user. The syntax is painful.

HARDWARE REQUIRED
Ethernet.

SOFTWARE REQUIRED

Internet Tool Catalog GENERIC-MANAGED-SYSTEM

NAME
Generic Managed System

KEYWORDS
manager; osi; cmis; unix; free, sourcelib

ABSTRACT
The Generic Managed System (GMS) implements the functions that would be common to any OSI managed system. These include the parseing of CMIS requests, selection of managed objects according to the scoping and filtering rules, handling of notifications and event forwarding discriminators etc. The intention is that the implementors should use the GMS as a basis for their own managed object implementations. A support environment is provided to assist with this.

MECHANISM
The GMS uses the UCL CMIP library plus a library of C++ objects representing common managed objects and attribute types.

CAVEATS
The system is still experimental, is subject to change and is not yet well documented.

BUGS
See above.

LIMITATIONS
None known.

HARDWARE REQUIRED
Has been tested on SUN 3 and SUN 4 architectures.

SOFTWARE REQUIRED
The ISODE protocol suite, BSD UNIX, UCL CMIP Library, GNU C++ (g++).

AVAILABILITY
The CMIP library and related management tools built upon it, known as OSIMIS (OSI Management Information Service), are publicly available from University College London, England via FTP and FTAM.

Internet Tool Catalog GETETHERS

NAME
getethers

KEYWORDS
Traffic; Ethernet; Ping; UNIX; Free

ABSTRACT
Getethers runs through all addresses on an ethernet segment (a.b.c.1 to a.b.c.254) and pings each address, and then determines the ethernet address for that host. It produces a list, in either plain ASCII, the file format for the Excelan Lanalyzer, or the file format for the Network General Sniffer, of hostname/ethernet address pairs for all hosts on the local nework. The plain ASCII list optionally includes the vendor name of the ethernet card in each system, to aid in the determination of the identity of unknown systems.

MECHANISM
Getethers uses a raw IP socket to generate ICMP echo requests and receive ICMP echo replies, and then examines the kernel ARP table to determine the ethernet address of each responding system.

CAVEATS
Assumes that the ethernet it is looking at is either a Class C IP network, or part of a Class B IP network that is subnetted with a netmask of 255.255.255.0. (This is easy to change, but it's compiled in.)

BUGS
None known.

LIMITATIONS
None.

HARDWARE REQUIRED
Has been tested on Sun-3 and Sun-4 (SPARC) systems under SunOS 4.1.x, DEC VAXes under 4.3BSD.

SOFTWARE REQUIRED
Runs under SunOS 4.x and 4.3BSD; should be easy to port to any other Berkeley-like system. Requires raw sockets and the ioctl calls to get at the ARP table.

AVAILABILITY AND CONTACT POINT FOR INFORMATION ABOUT THIS TOOL

Internet Tool Catalog GETONE_WELLFLEET

NAME
getone, getmany, getroute, getarp, getaddr, getif, getid.

KEYWORDS
manager, routing, status; IP; NMS, SNMP; UNIX.

ABSTRACT
These commands retrieve and format for display values of one or several MIB variables (RFC1066) using the SNMP (RFC1098). Getone and getmany retrieve arbitrary MIB variables; getroute, getarp, getaddr, and getif retrieve and display tabular information (routing tables, ARP table, interface configuration, etc.), and getid retrieves and displays system name, identifica tion and boot time.

Getone < target > < mibvariable > retrieves and displays the value of the designated MIB variable from the specified target system. The SNMP community name to be used for the retrieval can also be specified. Getmany works similarly for groups of MIB variables rather than individual values. The name of each variable, its value and its data type is displayed. Getroute returns information from the ipRoutingTable MIB structure, displaying the retrieved information in an accessible format. Getarp behaves similarly for the address translation table; getaddr for the ipAddressTable; and getif displays information from the interfaces table, supplemented with information from the ipAddressTable. Getid displays the system name, identification, ipFor warding state, and the boot time and date. All take a system name or IP address as an argument and can specify an SNMP community for the retrieval. One SNMP query is performed for each row of the table.

MECHANISM
Queries SNMP agent(s).

CAVEATS

AVAILABILITY
Hammer and anvil are copyrighted, though free. Copies are available from pub/eutil on husc6.harvard.edu.

Internet Tool Catalog HOPCHECK

NAME
hopcheck

KEYWORDS
routing; IP; ping; DOS; free.

ABSTRACT
Hopcheck is a tool that lists the gateways traversed by packets sent from the hopcheck-resident PC to a desti nation. Hopcheck uses the same mechanism as traceroute but is for use on IBM PC compatibles that have ethernet connections. Hopcheck is part of a larger TCP/IP pack age that is known as ka9q that is for use with packet radio. Ka9q can coexist on a PC with other TCP/IP packages such as FTP Inc's PC/TCP, but must be used independently of other packages. Ka9q was written by Phil Karn. Hopcheck was added by Katie Stevens, dkstevens@ucdavis.edu. Unlike traceroute, which requires a UNIX kernel mod, hopcheck will run on the standard, unmodified ka9q release.

MECHANISM
See the description in traceroute.

CAVEATS
See the description in traceroute.

BUGS
None known.

HARDWARE REQUIRED
IBM PC compatible with ethernet network interface card; ethernet card supported through FTP spec packet driver.

SOFTWARE REQUIRED
DOS.

AVAILABILITY
Free for radio amateurs and educational institutions; others should contact Phil Karn, karn@ka9q.bellcore.com. Available via anonymous FTP at ucdavis.edu, in the directory "dist/nethop".

Internet Tool Catalog INTERNET_ROVER

NAME
Internet Rover

KEYWORDS
status; IP, SMTP; curses, ping, spoof; UNIX; free, sourcelib.

ABSTRACT
Internet Rover is a prototype network monitor that uses multiple protocol "modules" to test network functional ity. This package consists of two primary pieces of code: the data collector and the problem display.

There is one data collector that performs a series of network tests, and maintains a list of problems with the network. There can be many display processes all displaying the current list of problems which is useful in a multi-operator NOC.

The display task uses curses, allowing many terminal types to display the problem file either locally or from a remote site. Full source is provided. The data collector is easily configured and extensible. Contri butions such as additional protocol modules, and shell script extensions are welcome.

MECHANISM
A configuration file contains a list of nodes, addresses, NodeUp? protocol test (ping in most cases), and a list of further tests to be performed if the node is in fact up. Modules are included to test TELNET, FTP, and SMTP. If the configuration contains a test that isn't recognized, a generic test is assumed, and a filename is checked for existence. This way users can create scripts that create a file if there is a prob lem, and the data collector simply checks the existence of that file to determine if there is problem.

CAVEATS
None.

BUGS
None known.

LIMITATIONS
This tool does not yet have the capability to perform actions based on the result of the test. Rather, it is intended for a multi-operator environment, and simply displays a list of what is wrong with the net.

HARDWARE REQUIRED
This software is known to run on Suns and IBM RTs.

SOFTWARE REQUIRED
Curses, 4.xBSD UNIX socket programming libraries, BSD ping.

AVAILABILITY
Full source available via anonymous FTP from merit.edu (35.1.1.42) in the ~ftp/pub/inetrover directory. Source and executables are public domain and can be freely distributed for non-commercial use. This pack age is unsupported, but bug reports and fixes may be sent to: wbn@merit.edu.

Internet Tool Catalog IOZONE

NAME
iozone

KEYWORDS
benchmark; nfs;; dos,hp,unix,vmx; free.

ABSTRACT
Software to assess the sequential file I/O capability of a system. May be useful as reference to compare against results obtained when files are accessed via NFS, Andrew, etc.

MECHANISM
This test writes a X MEGABYTE sequential file in Y byte chunks, then rewinds it and reads it back. [The size of the file should be big enough to factor out the effect of any disk cache.]. Finally, IOZONE deletes the temporary file. Options allow one to vary X and Y. In addition, 'auto test' runs IOZONE repeatedly using record sizes from 512 to 8192 bytes (adjustable), and file sizes from 1 to 16 megabytes (adjustable). It creates a table of results.

CAVEATS
The file is written (filling any cache buffers), and then read. If the cache is > = X MB, then most if not all the reads will be satisfied from the cache. However, if it is less than or equal to .5X MB, then NONE of the reads will be satisfied from the cache. This is becase after the file is written, a .5X MB cache will contain the upper .5 MB of the test file, but we will start reading from the beginning of the file (data which is no longer in the cache).

In order for this to be a fair test, the length of the test file must be AT LEAST 2X the amount of disk cache memory for your system. If not, you are really testing the speed at which your CPU can read blocks out of the cache (not a fair test).

BUGS
none known at this time.

LIMITATIONS
IOZONE does not normally test the raw I/O speed of your disk or system-em. It tests the speed of sequential I/O to actual files. Therefore, this measurement factors in the efficiency of you machines file system, operating system, C compiler, and C runtime library. It produces a measurement which is the number of bytes per second that your system can read or write to a file.

HARDWARE REQUIRED
This program has been ported and tested on the following computer operating systems:

Internet Tool Catalog LADDIS

NAME
LADDIS

KEYWORDS
benchmark, generator; NFS; spoof; unix; free.

ABSTRACT
LADDIS: A Multi-Vendor and Vendor-Neutral SPEC NFS Benchmark", Bruce Nelson, LADDIS Group & Auspex Systems.

Over the past 24 months, engineers from Legato, Auspex, Data General, DEC, Interphase, and Sun (LADDIS) met regularly to create the LADDIS NFS benchmark: an unbiased, standard, vendor-independent, scalable NFS performance test.

The purpose of the LADDIS benchmark is to give users a credible and undisputed test of NFS performance, and to give vendors a publishable standard performance measure that customers can use for load planning, system configuration, and equipment buying decisions. Toward this end, the LADDIS benchmark is being adopted by SPEC (the System Performance Evaluation Cooperative, creators of SPECmarks) as the first member of SPEC's System-level File Server (SFS) benchmark suite."

"In particular, we have had unexpected interest from some router vendors in using LADDIS to both rate and stress-test IP routers. This is because LADDIS can send back-to-back full-size packet trains, and because it can generate a 90%-Ethernet util on simulated "real" NFS workloads, just like routers encounter in the real world. But LADDIS is for local Ethernet or FDDI nets only, not WAN."

MECHANISM
Generates NFS requests and measures responsiveness of the server.

CAVEATS
"LADDIS is not released yet by SPEC, although a free beta version, quite stable, is available now as PRE-LADDIS. So you might want to put PRE-LADDIS in your listing, noting that full LADDIS availability from SPEC is expected by the end of 1992."

BUGS
The licensee is requested to direct beta test comments via electronicmail to:
"spec-preladdis-comments@riscee.pko.dec.com".

This alias will forward all comments to the SPECSFS mailing list (which includes the LADDIS Group).

LIMITATIONS
LADDIS is for local Ethernet or FDDI nets only, not WAN.

HARDWAE REQUIRED A host with LAN connectivity. Presumably, a host with enough horsepower to generate an adequate work load.

SOFTWARE REQUIRED
LADDIS is a sophisticated Unix-based NFS traffic generator program.

From: bnelson (Bruce Nelson)

Dear Person:

The SPEC PRE-LADDIS beta test process became operational on Monday, February 3, 1992. This email describes the process as announced during the LADDIS Group's presentation at UniForum '92 and also at Interop '91. The content of the beta test license and the license request process are consistent with the proposals approved by the SPEC Steering Committee at the January 1992 meeting in Milpitas, California.

The SPEC PRE-LADDIS beta test will consist of one beta test version of PRE-LADDIS distributed ONLY by electronic mail. The SPEC PRE-LADDIS Beta test software is licensed by SPEC, not by the LADDIS Group.

To obtain the PRE-LADDIS Beta test software, an individual must:


1. Request the SPEC PRE-LADDIS beta test License by electronic mail to "spec-preladdis-beta-test@riscee.pko.dec.com" with a subject line of "Request SPEC PRE-LADDIS Beta Test License".
2. Print a hardcopy of the license and sign.
3. Attach a cover letter written on the individual's company letterhead requesting the PRE-LADDIS Beta Test Kit.
4. U.S. Mail the signed license and cover letter to:
SPEC PRE-LADDIS Beta Test
c/o NCGA, 2722 Merrilee Drive, Suite 200
Fairfax, VA 22031

After completing these steps, the SPEC PRE-LADDIS beta test kit will be emailed to the requestor from riscee.pko.dec.com. The licensee is requested to direct beta test comments via electronic mail to "spec-preladdis-comments@riscee.pko.dec.com". This alias will forward all comments to the SPECSFS mailing list (which includes the LADDIS Group).

Note that PRE-LADDIS is ONLY available through electronic mail and ONLY through the process listed above in steps 1-4. If you do not have internet email available to you (which is unlikely if you are receiving THIS email), you must arrange delivery of PRE-LADDIS through some email-capable part of your organization, not through LADDIS members like Auspex, DEC, Sun, etc.

LAN Patrol is a full-featured network analyzer that provides essential information for effective fault and performance management. It allows network managers to easily monitor user activity, find traffic overloads, plan for growth, test cable, uncover intruders, balance network services, and so on. LAN Patrol uses state of the art data collection techniques to monitor all activity on a network, giving an accurate picture of how it is performing.

LAN Patrol's reports can be saved as ASCII files to disk, and imported into spreadsheet or database pro grams for further analysis.

MECHANISM
The LAN Patrol interface driver programs a standard interface card to capture all traffic on a network seg ment. The driver operates from the background of a standard PC, maintaining statistics for each station on the network. The information can be viewed on the PC's screen, or as a user-defined report output either to file or printer.

CAVEATS
None. Normal operation is completely passive, making LAN Patrol transparent to the network.

BUGS
None known.

LIMITATIONS
LAN Patrol can monitor up to 10,000 packets/sec on an AT class PC, and is limited to monitoring a maximum of 1024 stations for intervals of up to 30 days.

Because LAN Patrol operates at the physical level, it will only see traffic for the segment on which it is installed; it cannot see traffic across bridges.

HARDWARE REQUIRED
Computer: IBM PC/XT/AT, PS/2 Model 30, or compatible. Requires 512K memory and a hard drive or double-sided disk drive.

Display: Color or monochrome text. Color display allows color-coding of traffic information.

ABSTRACT
CXR/Digilog's LANVista family of protocol and statistical analyzers provide the tools to troubleshoot an Ethernet and Token Ring 4/16Mbps network. LANVista lets you capture frames to RAM and or disk, generate traffic for stress testing, test your network cable for fault isolation, and decode all 7 layers of many popular protocol stacks. LANVista's 100 family offers exceptional price/performance and a wide range of options. Combined with an integrated upgrade path to the fully distributed LANVista 200 system, the 100 line provides a reasonably priced entry into LAN management and protocol analysis.

All LANVista models are fully operable under Microsoft Windows. Under Windows, LANVista can be operated in the background, gathering data and alarms as other tasks are completed. Displayed data may easily be cut from LANVista and pasted into other Windows applications such as Excel, Lotus 1-2-3, Harvard Graphics, etc.

The versatile LANVista family can also be remotely controlled through the use of PC Anywhere, Commute, Carbon Copy, or other PC remote control packages. This feature allows the use of "co-pilot" mode which enables an operator at the central site to guide and train a remote operator through network management or analysis tasks.

All LANVista models provide features vital to effective network management and troubleshooting. Basic capabilities include: Network database, statistics based on the entire network and on a node basis, Token Ring functional address statistics, Bridged traffic statistics, Protocol statistics, logging of statistics to a printer or file of user definable alarms, Hardware Pre-Capture filtering, Post capture filtering, Playback of captured data, Traffic simulation and On-line context sensitive Help.

Internet Tool Catalog LANPROBE

NAME
LanProbe -- the HP 4990S LanProbe Distributed Analysis System.

KEYWORDS
alarm, manager, map, status, traffic; ethernet; eaves drop, NMS; proprietary.

ABSTRACT
The LanProbe distributed monitoring system performs remote and local monitoring of ethernet LANs in a pro tocol and vendor independent manner.

LanProbe discovers each active node on a segment and displays it on a map with its adapter card vendor name, ethernet address, and IP address. Additional informa tion about the nodes, such as equipment type and physi cal location can be entered in to the data base by the user.

When the NodeLocator option is used, data on the actual location of nodes is automatically entered and the map becomes an accurate representation of the physical lay out of the segment. Thereafter when a new node is installed and becomes active, or when a node is moved or becomes inactive, the change is detected and shown on the map in real time. The system also provides the network manager with precise cable fault information displayed on the map.

Traffic statistics are gathered and displayed and can be exported in (comma delimited) CSV format for further analysis. Alerts can be set on user defined thres holds.

Trace provides a remote protocol analyzer capability with decodes for common protocols.

Significant events (like power failure, cable breaks, new node on network, broadcast IP source address seen, etc.) are tracked in a log that is uploaded to Pro beView periodically.

ProbeView generates reports that can be manipulated by MSDOS based word processors, spreadsheets, and DBMS.

MECHANISM
The system consists of one or more LanProbe segment monitors and ProbeView software running under Microsoft Windows. The LanProbe segment monitor attaches to the end of an ethernet segment and monitors all traffic. Attachment can be direct to a thin or thick coax cable, or via an external transceiver to fiber optic or twist ed pair cabling. Network data relating to the segment is transferred to a workstation running ProbeView via RS-232, ethernet, or a modem connection.

ProbeView software, which runs on a PC/AT class works tation, presents network information in graphical displays.

The HP4992A NodeLocator option attaches to the opposite end of the cable from the HP4991A LanProbe segment mon itor. It automatically locates the position of nodes on the ethernet networks using coaxial cabling schemes.

CAVEATS
None.

BUGS
None known.

LIMITATIONS
None reported.

HARDWARE REQUIRED
HP 4991A LanProbe segment monitor HP 4992A NodeLocator (for optional capabilities) 80386 based PC capable of running MS-Windows

Internet Tool Catalog LANWATCH

NAME
LANWatch

KEYWORDS
alarm, analyzer, traffic; CHAOS, DECnet, DNS, ethernet, IP, OSI, ring, SMTP, star; eavesdrop; DOS; library, sourcelib.

ABSTRACT
LANWatch 2.0 is an inexpensive, powerful and flexible network analyzer that runs under DOS on personal com puters and requires no hardware modifications to either the host or the network. LANWatch is an invaluable tool for installing, troubleshooting, and monitoring local area networks, and for developing and debugging new protocols. Network managers using LANWatch can inspect network traffic patterns and packet errors to isolate performance problems and bottlenecks. Protocol developers can use LANWatch to inspect and verify proper protocol handling. Since LANWatch is a software-only package which installs easily in existing PCs, network technicians and field service engineers can carry LANWatch in their briefcase for convenient network analysis at remote sites.

LANWatch has two operating modes: Display and Examine. In Display Mode, LANWatch traces network traffic by displaying captured packets in real time. Examine Mode allows you to scroll back through stored packets to inspect them in detail. To select a subset of packets for display, storage or retrieval, there is an exten sive set of built-in filters. Using filters, LANWatch collects only packets of interest, saving the user from having to sort through all network traffic to isolate specific packets. The built-in filters include alarm, trigger, capture, load, save and search. They can be controlled separately to match on source or destination address, protocol, or packet contents at the hardware and transport layers. LANWatch also includes suffi cient source code so users can modify the existing filters and parsers or add new ones.

The LANWatch distribution includes executables and source for several post-processors: a TCP protocol analyzer, a node-by-node traffic analyzer and a dump file listing tool.

MECHANISM
Uses many common PC network interfaces by placing them in promiscuous mode and capturing traffic.

CAVEATS
Most PC network interfaces will not capture 100% of the traffic on a fully-loaded network (primarily missing back-to-back packets).

BUGS
None known.

LIMITATIONS
LANWatch can't analyze what it doesn't see (see Caveats).

HARDWARE REQUIRED
LANWatch requires a PC or PS/2 with a supported network interface card.

SOFTWARE REQUIRED
LANWatch runs in DOS. Modification of the supplied source code or creation of additional filters and parsers requires Microsoft C 5.1

AVAILABILITY
LANWatch is commercially available from FTP Software, Incorporated, 26 Princess Street, Wakefield, MA, 01880 (617 246-0900).

Internet Tool Catalog LLL_ENTM

NAME
ENTM -- Ethernet Traffic Monitor

KEYWORDS
traffic; ethernet, IP; eavesdrop; VMS; free.

ABSTRACT
ENTM is a screen-oriented utility that runs under VAX/VMS. It monitors local ethernet traffic and displays either a real time or cumulative, histogram showing a percent breakdown of traffic by ethernet pro tocol type. The information in the display can be reported based on packet count or byte count. The per cent of broadcast, multicast and approximate lost pack ets is reported as well. The screen display is updated every three seconds. Additionally, a real time, slid ing history window may be displayed showing ethernet traffic patterns for the last five minutes.

ENTM can also report IP traffic statistics by packet count or byte count. The IP histograms reflect infor mation collected at the TCP and UDP port level, includ ing ICMP type/code combinations. Both the ethernet and IP histograms may be sorted by ASCII protocol/port name or by percent-value. All screen displays can be saved in a file for printing later.

MECHANISM
This utility simply places the ethernet controller in promiscuous mode and monitors the local area network traffic. It preallocates 10 receive buffers and attempts to keep 22 reads pending on the ethernet dev ice.

CAVEATS
Placing the ethernet controller in promiscuous mode may severly slow down a VAX system. Depending on the speed of the VAX system and the amount of traffic on the lo cal ethernet, a large amount of CPU time may be spent on the Interrupt Stack. Running this code on any pro duction system during operational hours is discouraged.

BUGS
Due to a bug in the VAX/VMS ethernet/802 device driver, IEEE 802 format packets may not always be detected. A simple test is performed to "guess" which packets are in IEEE 802 format (DSAP equal to SSAP). Thus, some DSAP/SSAP pairs may be reported as an ethernet type, while valid ethernet types may be reported as IEEE 802 packets.

In some hardware configurations, placing an ethernet controller in promiscuous mode with automatic-restart enabled will hang the controller. Our VAX 8650 hangs running this code, while our uVAX IIs and uVAX IIIs do not.

LIMITATIONS
The user is required to have PHY_IO, TMPMBX and NETMBX privileges. When activated, the program first checks that the user process as enough quotas remaining (BYTLM, BIOLM, ASTLM and PAGFLQUO) to successfully run the program without entering into an involuntary wait state. Some quotas require a fairly generous setting.

The contents of IEEE 802 packets are not examined. Only the presence of IEEE 802 packets on the wire is reported.

The count of lost packets is approximated. If, after each read completes on the ethernet device, the utility detects that it has no reads pending on that device, the lost packet counter is incremented by one.

When the total number of bytes processed exceeds 7fffffff hex, all counters are automatically reset to zero.

HARDWARE REQUIRED
A DEC ethernet controller.

Internet Tool Catalog Interactive Network Map

NAME
map -- Interactive Network Map

KEYWORDS
manager, map; CHAOS, ethernet, IP, ring, star; NMS, ping, SNMP, X; UNIX; free, sourcelib.

ABSTRACT
Map draws a map of network connectivity and allows interactive examination of information about various components including whether hosts can be reached over the network.

The program is supplied with complete source and is written in a modular fashion to make addition of dif ferent protocols stacks, displays, or hardcopy devices relatively easy. This is one of the reasons why the initial version supports at least two of each. Contri butions of additional drivers in any of these areas will be welcome as well as porting to additional plat forms.

MECHANISM
Net components are pinged by use of ICMP echo and, optionally, CHAOS status requests and SNMP "gets." The program initializes itself from static data stored in the file system and therefore does not need to access the network in order to get running (unless the static files are network mounted).

CAVEATS
As of publication, the tool is in beta release.

BUGS
Several minor nits, documented in distribution files. Bug discoveries should be reported by email to Bug- Map@LCS.MIT.Edu.

LIMITATIONS
See distribution file for an indepth discussion of sys tem capabilities and potential.

HARDWARE REQUIRED
An X display is needed for interactive display of the map, non-graphical interaction is available in non- display mode. For hardcopy output a PostScript or Tek tronix 4692 printer is required.

SOFTWARE REQUIRED
BSD UNIX or related OS. IP/ICMP is required; CHAOS/STATUS and SNMP can be used but are optional. X-Windows is required for interactive display of the map.

AVAILABILITY
The program is Copyright MIT. It is available via anonymous FTP with a license making it free to use and distribute for non-commercial purposes. FTP to host FTP.LCS.MIT.Edu, directory nets.

Internet Tool Catalog NET_MONITOR

NAME
net_monitor

KEYWORDS
routing, status; DECnet, IP; curses, ping; UNIX, VMS; free, sourcelib.

ABSTRACT
Net_monitor uses ICMP echo (and DECnet reachability information on VAX/VMS) to monitor a network. The mon itoring is very simplistic, but has proved useful. It periodically tests whether hosts are reachable and reports the results in a full-screen display. It groups hosts together in common sets. If all hosts in a set become unreachable, it makes a lot of racket with bells, since it assumes that this means that some com mon piece of hardware that supports that set has failed. The periodicity of the tests, hosts to test, and groupings of hosts are controlled with a single configuration file.

The idea for this program came from the PC/IP monitor facility, but is an entirely different program with different functionality.

MECHANISM
Reachability is tested using ICMP echo facilities for TCP/IP hosts (and DECnet reachability information on VAX/VMS). A DECnet node is considered reachable if it appears in the list of hosts in a "show network" com mand issued on a routing node.

CAVEATS
This facility has been found to be most useful when run in a window on a workstation rather than on a terminal connected to a host. It could be useful if ported to a PC (looks easy using FTP Software's programming libraries), but this has not been done. Curses is very slow and cpu intensive on VMS, but the tool has been run in a window on a VAXstation 2000. Just don't try to run it on a terminal connected to a 11/750.

BUGS
None known.

LIMITATIONS
This tool is not meant to be a replacement for a more comprehensive network management facility such as is provided with SNMP.

HARDWARE REQUIRED
A host with a network connection.

SOFTWARE REQUIRED
Curses, 4.xBSD UNIX socket programming libraries (lim ited set) and some flavor of TCP/IP that supports ICMP echo request (ping). It has been run on VAX/VMS run ning WIN/TCP and several flavors of 4BSD UNIX (includ ing SunOS 3.2, 4.0, and 4.3BSD). It could be ported to any platform that provides a BSD-style programming li brary with an ICMP echo request facility and curses.

ABSTRACT
The NetMetrix Load Monitor is a distributed client-server monitoring tool for ethernet, token ring, and FDDI networks. A unique "dual" architecture provides compatibility with both RMON and X windows. RMON allows interoperability and an enterprise-wide view, while X windows enables much more powerful, intelligent applications at remote segments and saves network bandwidth.

The Load Monitor provides extensive traffic statistics. It looks at load by time interval, source node, destination node, application, protocol or packet size. A powerful ZOOM feature allows extensive correlational analysis which is displayed in a wide variety of graphs and tables.

You can answer questions such as: Which sources are generating most of the load on the network when it is most heavily loaded and where is this load going? Which source/destination pairs generate the most traffic over the day? Where should bridges and routers be located to optimally partition the network? How much load do applications, like the X Windows protocol, put on the network and who is generating that load when it is the greatest.

A floating license allows easy access to the software tool anywhere you need it.

Internet Tool Catalog NETMON_MITRE

NAME
NETMON and iptrace

KEYWORDS
traffic; IP; eavesdrop; UNIX; free.

ABSTRACT
NETMON is a facility to enable communication of net working events from the BSD UNIX operating system to a user-level network monitoring or management program. Iptrace is a program interfacing to NETMON which logs TCP-IP traffic for performance measurement and gateway monitoring. It is easy to build other NETMON-based tools using iptrace as a model.

NETMON resides in the 4.3BSD UNIX kernel. It is independent of hardware-specific code in UNIX. It is transparent to protocol and network type, having no internal assumptions about the network protocols being recorded. It is installed in BSD-like kernels by adding a standard function call (probe) to a few points in the input and output routines of the protocols to be logged.

NETMON is analogous to Sun Microsystems' NIT, but the interface tap function is extended by recording more context information. Aside from the timestamp, the choice of information recorded is up to the installer of the probes. The NETMON probes added to the BSD IP code supplied with the distribution include as context: input and output queue lengths, identification of the network interface, and event codes labeling packet dis cards. (The NETMON distribution is geared towards measuring the performance of BSD networking protocols in an IP gateway).

NETMON is designed so that it can reside within the monitored system with minimal interference to the net work processing. The estimated and measured overhead is around five percent of packet processing.

The user-level tool "iptrace" is provided with NETMON. This program logs IP traffic, either at IP-level only, or as it passes through the network interface drivers as well. As a separate function, iptrace produces a host traffic matrix output. Its third type of output is abbreviated sampling, in which only a pre-set number of packets from each new host pair is logged. The three output types are configured dynamically, in any combination.

OSITRACE, another logging tool with a NETMON interface, is available separately (and documented in a separate entry in this catalog).

MECHANISM
Access to the information logged by NETMON is through a UNIX special file, /dev/netmon. User reads are blocked until the buffer reaches a configurable level of full ness.

Several other parameters of NETMON can be tuned at com pile time. A diagnostic program, netmonstat, is included in the distribution.

CAVEATS
None.

Internet Tool Catalog NETscout

NAME
NETscout(tm)

KEYWORDS
Alarm, Analyzer, Manager, Status, Traffic; DECnet, Ethernet, IP, OSI, NFS, Ring, Star, Eavesdrop; NMS, SNMP; UNIX;

ABSTRACT
The NETscout family of distributed LAN Analyzer devices are intended to provide network users with a comprehensive capability to identify and isolate fault conditions in data communications networks. NETscout has the capability to collect wide ranging statistical data, to display selectively captured and fully decoded network traffic, to set user-defined alarm conditions, and to obtain real-time updates from all segments of a widely dispersed internetwork from a centralized SNMP-compatible network management console.

The NETscout family is based on standards so that operation may be realized in heterogeneous networks which constitute a multi-protocol, multi-topology, multi-vendor environment. The fundamental standards upon which NETscout is based are the Simple Network Management Protocol (SNMP), which defines the protocol for all inter-communications between NETscout devices, and the Remote Monitoring Management Information Base (RMON-MIB), which defines the type of information which is to be gathered and made available to the user for each network segment.

NETscout clients provide a full array of monitoring and analysis features including intelligent seven level decoding of all majorprotocol stacks: 

DOD including TCP/IP    XNS       Novell
DECNET including LAT    ISO       APPLETALK
IBM Token Ring          Vines     NETBIOS/SMB
SNMP including RMON-MIB SUN-NFS   SMT

NETscout agents support all nine groups of the RMON-MIB standard. NETscout agents can work with any SNMP-based network management system and currently support Ethernet and Token Ring.

MECHANISM
The operation of the NETscout family is divided into two distinct subcategories. The first is the "Client" which is the user console from which operational commands are issued and where all results and diagnostic information are displayed. In a NETscout topology it is feasible to have multiple clients active simultaneously within a single network. The second category is the "Agent", a hardware/software device which is attached to a specific network segment and which gathers statistical information for that segment as well as providing a window into that segment where network traffic may be observed and gathered for more detailed user analysis. A typical network will have multiple segments and multiple agents up to the point of having one agent for each logical network segment.

NETscout Model 9210 is a software package which, when combined in a Sun SPARCstation in conjunction with SunNet Manager running under Open Windows, implements the NETscout client function. SunNet Manager provides the background operational tools for client operation while the NETscout software provides application-specific functions related to RMON-MIB support as well as all software necessary to perform the protocol decode function. SunNet Manager also implements a network map file which includes a topographical display of the entire network and is the mechanism for selecting network elements to perform operations.

NETscout Model 9215 is a software package that operates in conjunction with SunNet Manager and implements the statistics monitoring function only. That is, it does not include the protocol decode function or the mechanism to retrieve actual data from a remote agent. It does, however, include complete statistics gathering and event and alarm generation.

Frontier NETscout Models 9510 and 9515, and Model 9610 and 9615 are agent software packages that implement selected network diagnostic functions when loaded into a Sun SPARCstation (9510, 9515) or a SynOptics LattisNet Hub (9610, 9615) respectively which is connected to an Ethernet network segment using conventional network interface hardware. Models 9510 and 9610 support all nine RMON-MIB groups including "filters" and "packet capture" and thus provide for complete protocol monitoring and decode when used with a client equipped with protocol decode software. Models 9515 an 9615 include support for seven RMON-MIB groups which excludes "filters" and "data capture" and therefore perform network monitoring only through collection and presentation of network statistics, events, and alarms. All models also support the MIB2 system and interface groups.

Frontier NETscout Models 9520 and 9525, and Model 9620 and 9625 are agent software packages that are identical in function to their respective models described above except that they are for use on Token Ring segments.

CAVEATS
The RMON-MIB standard for Token Ring applications has not yet beenformally released and is not approved. NETscout products correspond to the latest draft for Token Ring functions and will be updated as required to conform to the standard as it is approved.

BUGS
None known.

LIMITATIONS
None reported.

HARDWARE REQUIRED
Sun SPARCstation or LattisNet Hub depending upon Model number.

SOFTWARE REQUIRED
Sun OS 4.1.1 for client and agent, SunNet Manager for client.

MECHANISM
Netstat accesses operating system memory to read the kernel routing tables.

CAVEATS
Kernel data structures can change while netstat is run ning.

BUGS
None known.

LIMITATIONS
None reported.

HARDWARE REQUIRED
No restrictions.

SOFTWARE REQUIRED
BSD UNIX or related OS, or VMS.

AVAILABILITY
Available via anonymous FTP from uunet.uu.net, in directory bsd-sources/src/ucb. Available with 4.xBSD UNIX and related operating systems. For VMS, available as part of TGV MultiNet IP software package, as well as Wollongong's WIN/TCP.

Internet Tool Catalog NETWORK_INTEGRATOR

NAME
Network Integrator I

KEYWORDS
map, traffic; ethernet; UNIX.

ABSTRACT
This tool monitors traffic on network segments. All information is dumped to either a log file or, for real-time viewing, to a command tool window. Data is time-stamped according to date and time. Logging can continue for up to 24 hours.

The tool is flexible in data collection and presenta tion. Traffic filters can be specified according to header values of numerous protocols, including those used by Apple, DEC, Sun, HP, and Apollo. Bandwidth utilization can be monitored, as well as actual load and peak throughput. Additionally, the Network Integrator can analyze a network's topology, and record the location of all operational nodes on a network.

Data can be displayed in six separate formats of bar graphs. In addition, there are several routines for producing statistical summaries of the data collected.

MECHANISM
The tools work through RPC and XDR calls.

CAVEATS
Although the tool adds only little traffic to a net work, generation of statistics from captured files requires a significant portion of a workstation's CPU.

BUGS
None known.

LIMITATIONS
Must be root to run monitor. There does not seem to be a limit to the number of nodes, since it monitors by segments. The only major limitation is the amount of disk space that a user can commit to the log files. The size of the log files, however, can be controlled through the tool's parameters.

HARDWARE REQUIRED
Sun3 or Sun4.

SOFTWARE REQUIRED
4.0BSD UNIX or greater, or related OS.

Internet Tool Catalog NFSwatch

NAME
nfswatch

KEYWORDS
Traffic; Ethernet, IP, NFS; Curses, Eavesdrop; UNIX; Free

ABSTRACT
Nfswatch monitors all incoming ethernet traffic to an NFS file server and divides it into several categories. The number and percentage of packets received in each category is displayed on the screen in a continuously updated display.

By default, nfswatch monitors all packets destined for the local host over a single network interface. Options are provided to specify the specific interface to be monitored, or all interfaces at once. NFS traffic to the local host, to a remote host, from a specific host, between two hosts, or all NFS traffic on the network may be monitored.

Categories of packets monitored and counted include: ND Read, ND Write, NFS Read, NFS Write, NFS Mount, Yellow Pages (NIS), RPC Authorization, Other RPC, TCP, UDP, ICMP, RIP, ARP, RARP, Ethernet Broadcast, and Other.

Packets are also tallied either by file system or file (specific files may be watched as an option), NFS procedure name (RPC call), or NFS client hostname.

Facilities for taking "snapshots" of the screen, as well as saving data to a log file for later analysis (the analysis tool is included) are also available.

MECHANISM
Nfswatch uses the Network Interface Tap, nit(4) under SunOS 4.x, and the Packet Filter, packetfilter(4), under Ultrix 4.x, to place the ethernet interface into promiscuous mode. It filters out NFS packets, and decodes the file handles in order to determine how to count the packet.

CAVEATS
Because the NFS file handle is a non-standard (server private) piece of data, nfswatch must be modified to understand file handles used by various implementations. It currently knows about the SunOS 4.x and Ultrix file handle formats.

BUGS
Does not monitor FDDI interfaces. (It should be a simple change, but neither author has access to a system with FDDI interfaces for testing.)

LIMITATIONS
Up to 256 exported file systems and 256 individual files can be monitored at any time.

Only NFS requests are counted; the NFS traffic generated by a server in response to those packets is not counted.

HARDWARE REQUIRED
Any Ultrix system (VAX or DEC RISC hardware)

SOFTWARE REQUIRED
Ultrix release 4.0 or later. For Ultrix 4.1, may require the patched "if_ln.o" kernel module, available from Digital's Customer Support Center.

Internet Tool Catalog NNSTAT

NAME
NNStat

KEYWORDS
manager, status, traffic; ethernet, IP; eavesdrop, NMS; UNIX; free.

ABSTRACT
NNStat is a collection of programs that provides an internet statistic collecting capability. The NNStat strategy for statistic collection is to collect traffic statistics via a promiscuous ethernet tap on the local networks, versus instrumenting the gateways. If all traffic entering or leaving a network or set of net works traverses a local ethernet, then by stationing a statistic gathering agent on each local network a pro file of network traffic can be gathered. Statistical data is retrieved from the local agents by a global manager.

A program called "statspy" performs the data gathering function. Essentially, statspy reads all packets on an ethernet interface and records all information of interest. Information of interest is gathered by exa mining each packet and determining if the source or destination IP address is one that is being monitored, typically a gateway address. If so then the contents of the packet are examined to see if they match further criteria.

A program called "collect" performs global data collec tion. It periodically polls various statspy processes in the domain of interest to retrieve locally logged statistical data.

The NNSTAT distribution comes with several sample awk programs which process the logged output of the collect program.

MECHANISM
Local agents (statspy processes) collect raw traffic data via a promiscuous ethernet tap. Statistical, fil tered or otherwise reduced data is retrieved from the local agents by a global manager (the "collect" pro cess).

CAVEATS
None.

BUGS
Bug fixes, extensions, and other pointers are discussed in the electronic mail forum, bytecounters. To join, send a request to bytecounters-request@venera.isi.edu. Forum exchanges are archived in the file bytecounters/bytecounters.mail, available via anonymous FTP from venera.isi.edu.

LIMITATIONS
NNStat presumes a topology of one or more long haul networks gatewayed to local ethernets.

A kernel mod required to run with SunOS4. These mods are described in the bytecounters archive.

HARDWARE REQUIRED
Ethernet interface. Sun 3, Sun 4 (SPARC), or PC RT workstation.

SOFTWARE REQUIRED
Distribution is for BSD UNIX, could easily be adapted to any UNIX with promiscuous ethernet support.

AVAILABILITY
Distribution is available via anonymous FTP from venera.isi.edu, in file pub/NNStat.tar.Z. Documenta tion is in pub/NNStat.userdoc.ms.Z.

Internet Tool Catalog NOCOL(8)

NAME
nocol - network monitoring tools for an IP network

SYNOPSIS
This is an overview of the NOCOL software.

DESCRIPTION
NOCOL (Network Operations Center On-Line) is a collection of network monitoring programs that run on Unix systems. The software consists of a number of monitoring agents that poll various parameters from any system and put it in a format suitable for post-processing. The post-processors can be a display agent, an automated troubleshooting program, an event logging program, etc. Presently, monitors for tracking reachability, SNMP traps, data throughput rate, and nameservers have been developed and are in use. Addition of more monitoring agents is easy and they will be added as necessary. A display agent nocol(1) using curses has already been developed. Work on an "intelligent" module is currently in progress for event logging and some automatic troubleshooting.

All data collected by the monitoring agents follows a fixed (non-readable) format. Each data entry is termed an event in NOCOL, and each event has certain flags and severity associated with it. The display agent nocol(1), displays the output of these monitoring agents depending on the severity of the event. There can be multiple displays running simultanously and all process the same set of monitored data.

There are four levels of severity associated with an event- CRITICAL, ERROR, WARNING and INFO. The severity level is controlled independently by the monitoring agents, and the decision to raise or set an event's severity to any level depends on the logic imbedded in the monitoring agent.

As an example, for the pingmon(8) monitor, if a site is unreachable via ping, it would be assigned a severity of WARNING by pingmon, which would then elevate to CRITICAL if the site is still unreachable after some time. In the case of trapmon(8), an SNMP trap message of EGP neighbor lost would be directly assigned a severity level of CRITICAL, while an Warm Start trap is assigned a severity of WARNING.

The display agent (and other data post-processors) would use this event severity to decide whether to display it (or troubleshoot/log it) depending on the user selected display severity level.

The software is very flexible and allows enhancements and development with a minimum amount of effort. The display module processes all the files present in the data directory, and displays them sequentially. This allows new monitoring programs to simply start generating data in the data directory and the display module will automatically start displaying the new data. The monitoring tools can be changed, and the only element that has to remain common between all the modules is the EVENT data structure.

CURRENT MODULES
NOCOL presently consists of the following modules:

nocol

which simply displays the data collected by the monitoring agents. It uses the curses screen management system to support a wide variety of terminal types. The criterion for displaying an event is:

1. Severity level of the event is higher than the severity level set in the display.

2. The display filter (if set) matches some string in the event line.

The display can be in regular 80 column mode or in extended 132 column mode. Critical events are displayed in reverse video (if the terminal type supports it). Additional features like displaying informational messages in a part of the window, automatic resizing window sizes, operator acknowledgement via a bell when a new event goes critical are also available.

ippingmon
which monitors the reachability of a site via "ICMP" ping packets (ICMP was preferred over SNMP for many obvious reasons). This program can use the default out put from the system's ping program, but an accompanying program ( multiping) can ping multiple IP sites at the same time and is preferable for monitoring a large list of sites. A site is marked unreachable if a certain number of packets is lost, and the severity level is increased each time that the site tests unreachable.

osipingmon
which is similar to the ippingmon module but uses the OSI ping program instead. No multiple ping program for OSI sites has been developed at this time. The only requirement is that the system's ping program output match the typical BSD IP ping program's output.

nsmon
which monitors the nameservers (named) on the list of specified hosts. It periodically sends an SOA query for the default domain and if the queried nameservers cannot resolve the query, then the site is elevated to CRITICAL status.

tpmon
For monitoring the throughput (kbits per second) to a list of hosts. The program connects to the discard socket on the remote machine (using a STREAM socket) and sends large packets for a small amount of time to evaluate the effective throughput. It elevates a site to WARNING level if the throughput drops below a certain threshold (set in the configuration file).

trapmon
Converts all SNMP traps into a format suitable for displaying using NOCOL. The severity of the various traps is preset (and can be changed during compilation time).

PLATFORM
Any Unix system with the curses screen management library and IP (Internet Protocol) programming facility. It has been tested on Sun Sparc 4.1.1, Ultrix, and NeXT systems. Porting to other platforms might require minor adjustments depending on the vagaries of the different vendors (mostly in the include files).

AVAILABILITY
NOCOL was developed at JvNCnet and has been in use for monitoring the JvNCnet wide area network since 1989. It is available via anonymous FTP from ftp.jvnc.net under pub/jvncnet-packages/nocol.tar.Z. The system running at JvNCet can be viewed by logging into the host nocol.jvnc.net with username nocol (an rlogin instead of telnet will handle your X window terminal types better). To be added to the NOCOL mailing list (for future updates and bug fixes), send a message to nocol-users- request@jvnc.net with your email address.

FUTURE DEVELOPMENTS

Possible future enhancements are:

1. Event logging.

2. Addition of an automated troubleshooting mechanism when a site severity level reaches a particular level.

3. SNMP monitors to watch the state of certain vari ables (interface errors, packet rate, route state changes).

AUTHOR
The software was developed at JvNCnet over a period of time. The overall design and initial development was done by Vikas Aggarwal and Sze-Ying Wuu. Additional development is being done and coordinated by Vikas Aggarwal (vikas@jvnc.net). Copyright 1992 JvNCnet. (See the file COPYRIGHT for full details)

Internet Tool Catalog NPRV

NAME
NPRV -- IP Node/Protocol Reachability Verifier

KEYWORDS
map, routing, status; IP; ping; VMS; free.

ABSTRACT
NPRV is a full-screen, keypad-oriented utility that runs under VAX/VMS. It allows the user to quickly scan through a user-defined list of IP addresses (or domain names) and verify a node's reachability. The node's reachability is determined by performing an ICMP echo, UDP echo and a TCP echo at alternating three second intervals. The total number of packets sent and received are displayed, as well as the minimum, average and maximum round-trip times (in milliseconds) for each type of echo. Additionally, a "trace route" function is performed to determine the path from the local sys tem to the remote host. Once all of the trace route information has filled the screen, a "snapshot" of the screen can be written to a text file. Upon exiting the utility, these text files can be used to generate a logical network map showing host and gateway intercon nectivity.

MECHANISM
The ICMP echo is performed by sending ICMP ECHO REQUEST packets. The UDP and TCP echoes are performed by con necting to the UDP/TCP echo ports (port number 7). The trace route information is compiled by sending alter nating ICMP ECHO REQUEST packets and UDP packets with very large destination UDP port numbers (in two passes). Each packet is initially sent with a TTL (time to live) of 1. This should cause an ICMP TIME EXCEEDED error to be generated by the first routing gateway. Then each packet is sent with a TTL of 2. This should cause an ICMP TIME EXCEEDED error to be generated by the second routing gateway. Then each packet is sent with a TTL of 3, and so on. This pro cess continues until an ICMP ECHO REPLY or UDP PORT UNREACHABLE is received. This indicates that the remote host has been reached and that the trace route information is complete.

CAVEATS
This utility sends one echo packet per second (ICMP, UDP or TCP), as well as sending out one trace route packet per second. If a transmitted trace route packet is returned in less than one second, another trace route packet is sent in 100 milliseconds. This could cause a significant amount of contention on the local network.

BUGS
None known. Please report any discovered bugs to the author at: Allen Sturtevant National Magnetic Fusion Energy Computer Center Lawrence Livermore National Laboratory P.O. Box 808; L-561 Livermore, CA 94550 Phone : (415) 422-8266 E-Mail: sturtevant@ccc.nmfecc.gov

LIMITATIONS
The user is required to have SYSPRV privilege to per form the ICMP Echo and trace route functions. The utility will still run with this privilege disabled, but only the UDP Echo and TCP Echo information will be displayed. This utility is written in C, but unfor tunately it cannot be easily ported over to UNIX since many VMS system calls are used and all screen I/O is done using the VMS Screen Management Routines.

This program is useful for converting a hostname into an IP address (and vice versa), determining the name servers for a domain , listing the contents of a domain, displaying any type of DNS record, such as MX, CNAME, SOA, etc., diagnosing name server problems.

By default, nslookup will query the default name server but you can specify a different server on the command line or from a configuration file. You can also specify different values for the options that control the resolver routines.

MECHANISM
The program formats, sends and receives DNS (RFC 1034) queries.

CAVEATS
None.

BUGS
None known.

LIMITATIONS
None known.

HARDWARE REQUIRED
No restrictions.

SOFTWARE REQUIRED
BSD UNIX or related OS, or VMS.

AVAILABILITY
NSLookup is included in the BIND distribution.

Available via anonymous FTP from uunet.uu.net, in directory /networking/ip/dns/bind. Available with 4.xBSD UNIX and related operating systems. For VMS, available as part of TGV MultiNet IP software package, as well as Wollongong's WIN/TCP.

Internet Tool Catalog OSITRACE

NAME
OSITRACE

KEYWORDS
traffic; OSI; eavesdrop; UNIX; free.

ABSTRACT
OSITRACE is a network performance tool that displays information about ISO TP4 connections. One line of output is displayed for each packet indicating the time, source, destination, length, packet type, sequence number, credit, and any optional parameters contained in the packet. Numerous options are avail able to control the output of OSITRACE.

To obtain packets to analyze, OSITRACE uses Sun Microsystems' Network Interface Tap (NIT) in SunOS 3.4, 3.5, and 4.0.X. OSITRACE may also obtain data from the NETMON utility which is described as another tool entry.

In Sun systems, OSITRACE may be easily installed: OSI kernel support is not needed, nor is any other form of OSI software support.

MECHANISM
This tool has been designed in such a way that code to process different protocol suites may be easily added. As such, OSITRACE also has the ability to trace the DOD TCP protocols.

CAVEATS
None.

Internet Tool Catalog SNIFFER

NAME
Sniffer

KEYWORDS
analyzer, generator, traffic; DECnet, ethernet, IP, NFS, OSI, ring, SMTP, star; eavesdrop; standalone.

ABSTRACT
The Network General Sniffer is a protocol analyzer for performing LAN diagnostics, monitoring, traffic genera tion, and troubleshooting. The Sniffer protocol analyzer has the capability of capturing every packet on a network and of decoding all seven layers of the OSI protocol model. Capture frame selection is based on several different filters: protocol content at lower levels; node addresses; pattern matching (up to 8 logically-related patterns of 32 bytes each); and des tination class. Users may extend the protocol interpretation capability of the Sniffer by writing their own customized protocol interpreters and linking them to the Sniffer software.

The Sniffer displays network traffic information and performance statistics in real time, in user-selectable formats. Numeric station addresses are translated to symbolic names or manufacturer ID names. Network activities measured include frames accepted, Kbytes accepted, and buffer use. Each network version has additional counters for activities specific to that network. Network activity is expressed as frames/second, Kbytes/second, or per cent of network bandwidth utilization.

Data collection by the Sniffer may be output to printer or stored to disk in either print-file or spread-sheet format.

Protocol suites understood by the Sniffer include: Banyan Vines, IBM Token-Ring, Novell Netware, XNS/MS- Net (3Com 3+), DECnet, TCP/IP (including SNMP and applications-layer protocols such as FTP, SMTP, and TELNET), X Windows (for X version 11), NFS, and several SUN proprietary protocols (including mount, pmap, RPC, and YP). Supported LANs include: ethernet, Token-ring (4Mb and 16Mb versions), ARCNET, StarLAN, IBM PC Net work (Broadband), and Apple Localtalk Network.

MECHANISM
The Sniffer is a self-contained, portable protocol analyzer that require only AC line power and connection to a network to operate. Normally passive (except when in Traffic Generator mode), it captures images of all or of selected frames in a working buffer, ready for immediate analysis and display.

The Sniffer is a standalone device. Two platforms are available: one for use with single network topologies, the other for use with multi-network topologies. Both include Sniffer core software, a modified network interface card (or multiple cards), and optional proto col interpreter suites.

All Sniffer functions may be remotely controlled from a modem-connected PC. Output from the Sniffer can be imported to database or spreadsheet packages.

CAVEATS
In normal use, the Sniffer is a passive device, and so will not adversely effect network performance. Perfor mance degradation will be observed, of course, if the Sniffer is set to Traffic Generator mode and connected to an active network.

BUGS
None known.

LIMITATIONS
None reported.

HARDWARE REQUIRED
None. The Sniffer is a self-contained unit, and includes its own interface card. It installs into a network as would any normal workstation.

SOFTWARE REQUIRED
None.

AVAILABILITY
The Sniffer is available commercially. For information on your local representative, call or write:

ABSTRACT
The SNMP Development Kit comprises C Language source code for a programming library that facilitates access to the management services of the SNMP (RFC 1098). Sources are also included for a few simple client applications whose main purpose is to illustrate the use of the library. Example client applications query remote SNMP agents in a variety of modes, and generate or collect SNMP traps. Code for an example SNMP agent that supports a subset of the Internet MIB (RFC 1066) is also included.

MECHANISM
The Development Kit facilitates development of SNMP- based management applications -- both clients and agents. Example applications execute SNMP management operations according to the values of command line arguments.

CAVEATS
None.

BUGS
Fixed in the next release.

LIMITATIONS
None reported.

HARDWARE REQUIRED
The SNMP library source code is highly portable and runs on a wide range of platforms.

SOFTWARE REQUIRED
The SNMP library source code has almost no operating system dependencies and runs in a wide range of environments. Certain portions of the example SNMP agent code are specific to the 4.3BSD implementation of the UNIX system for the DEC MicroVAX.

AVAILABILITY
The Development Kit is available via anonymous FTP from host allspice.lcs.mit.edu. The copyright for the Development Kit is held by the Massachusetts Institute of Technology, and the Kit is distributed without charge according to the terms set forth in its code and documentation. The distribution takes the form of a UNIX tar file.

Bug reports, questions, suggestions, or complaints may be mailed electronically to snmp-dk@ptt.lcs.mit.edu, although no response in any form is guaranteed. Dis tribution via UUCP mail may be arranged by contacting the same address. Requests for hard-copy documentation or copies of the distribution on magnetic media are never honored.

Internet Tool Catalog SNMP_Libraries_SNMP_RESEARCH

NAME
SNMP Libraries and Utilities from SNMP Research.

KEYWORDS
alarm, control, manager, map, security, status; bridge, DECnet, Ethernet, FDDI, IP, OSI, ring, star; NMS, SNMP; DOS, UNIX, VMS; sourcelib.

ABSTRACT
The SNMP Libraries and Utilities serve two purposes:

1) to act as building blocks for the construction of SNMP-based agent and manager applications; and

2) to act as network management tools for network fire fighting and report generation.

The libraries perform ASN.1 parsing and generation tasks for both network management station applications and network management agent applications. These libraries hide the details of ASN.1 parsing and generation from application writers and make it unnecessary for them to be expert in these areas. The libraries are very robust with considerable error checking designed in. The several command line utilities include applications for retrieving one or many variables, retrieving tables, or effecting commands via the setting of remote network management variables.

MECHANISM
The parsing is performed via recursive descent methods. Messages are passed via the Simple Network Management Protocol (SNMP).

CAVEATS
None.

BUGS
None known.

LIMITATIONS
The monitored and managed nodes must implement the SNMP over UDP per RFC 1157 or must be reachable via a proxy agent.

HARDWARE REQUIRED
This software has been ported to numerous platforms including workstations, general-purpose timesharing systems, and embedded hardware in intelligent network devices such as repeaters, bridges, and routers.

SOFTWARE REQUIRED
C compiler, TCP/IP library.

Internet Tool Catalog SPIDERMONITOR

NAME
SpiderMonitor P220, K220 and SpiderAnalyzer P320, K320

KEYWORDS
alarm, analyzer, generator, traffic; DECnet, ethernet, IP, OSI; eavesdrop; standalone; sourcelib.

ABSTRACT
The SpiderMonitor and SpiderAnalyzer are protocol analyzers for performing ethernet LAN diagnostics, mon itoring, traffic generation, and troubleshooting. The SpiderMonitor has the capability of capturing every packet on a network and of decoding the first four layers of the OSI protocol model. The SpiderAnalyzer has additional software for decoding higher protocol layers. Protocol suites understood: TCP/IP (including SNMP and applications-layer protocols), OSI, XNS, DEC- net and IPX. User-definable decodes can be written in 'C' with the Microsoft version 5.0 'C' compiler. A decode guide is provided.

The SpiderAnalyzer supports multiple simultaneous filters for capturing packets using predefined patterns and error states. Filter patterns can also trigger on NOT matching 1 or more filters, an alarm, or a speci fied time.

The SpiderAnalyzer can also employ TDR (Time Domain Reflectometry) to find media faults, open or short cir cuits, or transceiver faults. It can transmit OSI, XNS, and Xerox link-level echo packets to user- specified stations, performs loop round tests.

In traffic generation mode, the SpiderAnalyzer has the ability to generate packets at random intervals of ran dom lengths or any combination of random or fixed interval or length, generation of packets with CRC errors, or packets that are too short, or packets that are too long.

Output from the SpiderMonitor/Analyzer can be imported to database or spreadsheet packages.

MECHANISM
The SpiderMonitor and Spider Analyzer are available as stand-alone, IBM PC compatible packages based upon a Compaq III portable system, or as a plug-in boards for any IBM XT/AT compatible machine. The model 220 (Spi derMonitor) systems provide a functional base suited for most network management needs. The model 320 (Spi derAnalyzer) systems provide extended functionality in the development mode and traffic generation mode as well more filtering capabilities than the 220 models.

CAVEATS
Traffic generation will congest an operational ether net.

BUGS
None known.

LIMITATIONS
Monitoring of up to 1024 stations and buffering of up to 1500 packets. The model 220 provides for 3 filters with a filter depth of 46 bytes. The model 320 pro vides for 4 filters and a second level of filtering with a filter depth of 64 bytes.

Internet Tool Catalog SPIMS

NAME
SPIMS -- the Swedish Institute of Computer Science (SICS) Protocol Implementation Measurement System tool.

KEYWORDS
benchmark, debugger; IP, OSI; spoof; UNIX.

ABSTRACT
SPIMS is used to measure the performance of protocol and "protocol-like" services including response time (two-way delay), throughput and the time to open and close connections. It has been used to:

o benchmark alternative protocol implementations,

o observe how performance varies when parameters in specific implementations have been varied (i.e., to tune parameters).

SPIMS currently has interfaces to the DoD Internet Pro tocols: UDP, TCP, FTP, SunRPC, the OSI protocols from the ISODE 4.0 distribution package: FTAM, ROSE, ISO TP0 and to Sunlink 5.2 ISO TP4 as well as Stanford's VMTP. Also available are a rudimentary set of benchmarks, stubs for new protocol interfaces and a user manual.

For an example of the use of SPIMS to tune protocols, see: Nordmark & Cheriton, "Experiences from VMTP: How to achieve low response time," IFIP WG6.1/6.4: Protocols for High-Speed Networks, May 1989, Zurich. To be published.

For an example of how SPIMS can be used to benchmark protocols, see:

Gunningberg, Bjorkman, Nordmark, Sjodin, Pink & Stromqvist "Application Protocols and Performance Benchmarks", IEEE Communications Magazine, June 1989, Vol. 27, No.6, pp 30-36.

Sjodin, Gunningberg, Nordmark, & Pink, "Towards Protocol Benchmarks', IFIP WG6.1/6.4 Protocols for High-Speed Networks, May 1989, Zurich, pp 57-67

MECHANISM
SPIMS runs as user processes and uses a TCP connection for measurement set-up. Measurements take place between processes over the measured protocol. SPIMS generates messages and transfers them via the measured protocol service according to a user-supplied specifi cation. SPIMS has a unique measurement specification language that is used to specify a measurement session. In the language there are constructs for different application types (e.g., bulk data transfer), for specifying frequency and sequence of messages, for dis tribution over message sizes and for combining basic specifications. These specifications are independent of both protocols and protocol implementations and can be used for benchmarking. For more details on the internals of SPIMS, see:

Nordmark & Gunningberg, "SPIMS: A Tool for Protocol Implementation Performance Measurements" Proc. of 13:th Conf. on Local Computer Networks, Minneapolis 1989, pp 222-229.

CAVEATS
None.

BUGS
None known.

LIMITATIONS
None reported.

HARDWARE REQUIRED
No restrictions.

SOFTWARE REQUIRED
SPIMS is implemented on UNIX, including SunOS 4., 4.3BSD UNIX, DN (UNIX System V, with extensions) and Ultrix 2.0/3.0. It requires a TCP connection for meas urement set-up. No kernel modifications or any modifi cations to measured protocols are required.

Internet Tool Catalog SPRAY_SUN

NAME
spray

KEYWORDS
benchmark, generator; IP; ping; UNIX.

ABSTRACT
Spray is a traffic generation tool that generates RPC or UDP packets, or ICMP Echo Requests. The packets are sent to a remote procedure call application at the des tination host. The count of received packets is retrieved from the remote application after a certain number of packets have been transmitted. The differ ence in packets received versus packets sent represents (on a LAN) the packets that the destination host had to drop due to increasing queue length. A measure of throughput relative to system speed and network load can thus be obtained.

MECHANISM
See above.

CAVEATS
Spray can congest a network.

BUGS
None known.

LIMITATIONS
None reported.

HARDWARE REQUIRED
No restrictions.

Internet Tool Catalog TCPLOGGER

NAME
tcplogger

KEYWORDS
traffic; IP; eavesdrop; UNIX; free.

ABSTRACT
Tcplogger consists of modifications to the 4.3BSD UNIX source code, and a large library of post-processing software. Tcplogger records timestamped information from TCP and IP packets that are sent and received on a specified connection. For each TCP packet, information such as sequence number, acknowledgement sequence number, packet size, and header flags is recorded. For an IP packet, header length, packet length and TTL values are recorded. Customized use of the TCP option field allows the detection of lost or duplicate pack ets.

MECHANISM
Routines of 4.3BSD UNIX in the netinet directory have been modified to append information to a log in memory. The log is read continuously by a user process and written to a file. A TCP option has been added to start the logging of a connection. Lots of post processing software has been written to analyze the data.

CAVEATS
None.

BUGS
None known.

LIMITATIONS
To get a log at both ends of the connection, the modi fied kernel should be run at both the hosts.

All connections are logged in a single file, but software is provided to filter out the record of a sin gle connection.

HARDWARE REQUIRED
No restrictions.

SOFTWARE REQUIRED
4.3BSD UNIX (as modified for this tool).

AVAILABILITY
Free, although a 4.3BSD license is required. Contact Olafur Gudmundsson (ogud@cs.umd.edu).

Internet Tool Catalog TRACEROUTE

NAME
traceroute

KEYWORDS
routing; IP; ping; UNIX, VMS; free.

ABSTRACT
Traceroute is a tool that allows the route taken by packets from source to destination to be discovered. It can be used for situations where the IP record route option would fail, such as intermediate gateways dis carding packets, routes that exceed the capacity of an datagram, or intermediate IP implementations that don't support record route. Round trip delays between the source and intermediate gateways are also reported allowing the determination of individual gateways con tribution to end-to-end delay.

Enhanced versions of traceroute have been developed that allow specification of loose source routes for datagrams. This allows one to investigate the return path from remote machines back to the local host.

MECHANISM
Traceroute relies on the ICMP TIME_EXCEEDED error reporting mechanism. When an IP packet is received by an gateway with a time-to-live value of 0, an ICMP packet is sent to the host which generated the packet. By sending packets to a destination with a TTL of 0, the next hop can be identified as the source of the ICMP TIME EXCEEDED message. By incrementing the TTL field the subsequent hops can be identified. Each packet sent out is also time stamped. The time stamp is returned as part of the ICMP packet so a round trip delay can be calculated.

CAVEATS
Some IP implementations forward packets with a TTL of 0, thus escaping identification. Others use the TTL field in the arriving packet as the TTL for the ICMP error reply, which delays identification.

Sending datagrams with the source route option will cause some gateways to crash. It is considered poor form to repeat this behavior.

BUGS
None known.

LIMITATIONS
Most versions of UNIX have errors in the raw IP code that require kernel mods for the standard version of traceroute to work. A version of traceroute exists that runs without kernel mods under SunOS 3.5 (see below), but it only operates over an ethernet inter face.

HARDWARE REQUIRED
No restrictions.

SOFTWARE REQUIRED
BSD UNIX or related OS, or VMS.

AVAILABILITY
Available by anonymous FTP from ftp.ee.lbl.gov, in file traceroute.tar.Z. It is also available from uc.msc.umn.edu.

A version of traceroute that supports Loose Source Record Route, along with the source code of the required kernel modifications and a Makefile for installing them, is available via anonymous FTP from zerkalo.harvard.edu, in directory pub, file traceroute_pkg.tar.Z.

A version of traceroute that runs under SunOS 3.5 and does NOT require kernel mods is available via anonymous FTP from dopey.cs.unc.edu, in file ~ftp/pub/traceroute.tar.Z.

For VMS, traceroute is available as part of TGV Mul tiNet IP software package.

Internet Tool Catalog UNISYS-PARAMAX

NAME
Paramax Network Security Server

KEYWORDS
alarm, control, manager, security, status; ethernet, FDDI, IP; X; UNIX.

ABSTRACT
The Paramax Network Security Server (NSS) is a security officer's tool for centralized security management of TCP/IP-based networks. The NSS provides capability for collection, on-line storage, maintenance, and correlation of audit data from hosts, workstations, servers, and network devices. Through the X window based user interface, a security officer can review and analyze this audit data at the NSS, select and request filtered portions of host audit data, and receive and analyze security alerts from across the network. The NSS supports centralized access control of network resources through its capability to create and update user and host access permissions data. The user access permissions data identifies network addresses that each user is permitted to access. The host access permissions data identifies network addresses between which communication is permitted. The NSS supports centralized management of user authentication data (user IDs and passwords) and other user data for use by hosts, workstations, and servers in the network. It generates pseudo-random pronounceable passwords for selection and assignment to users by the security officer.

The NSS deadman timer locks the NSS screen or logs the security officer off the NSS after periods of inactivity. A biometric authentication device is optional for rigorous fingerprint authentication of users at the NSS, and logins to the NSS itself are permitted only at the console. The NSS currently provides centralized security management for a System High Network. It is being upgraded for a Compartmented Mode environment.

MECHANISM
The NSS uses the Audit Information Transfer Protocol (AITP) for the transfer of security alerts and audit data. AITP is NOT proprietary, and the specification is available from the address listed below. Access to the NSS audit database is provided via the Structured Query Language (SQL).

CAVEATS
None.

BUGS
None known.

LIMITATIONS
None reported.

Internet Tool Catalog XNETDB

NAME
Xnetdb

KEYWORDS
database, manager, map, monitoring, status; IP; Ping, SNMP, Unix, X; free.

ABSTRACT
Xnetdb is a network monitoring tool based on X Windows and SNMP which also has integrated database and statistic viewing capabilities. Xnetdb will determine and display the status of routers and circuits it has been told to monitor by querying the designated sites and displaying the result. It can also query the status of certain designated SNMP variables, such as a default route for an important router. Additionally, it also has integrated database functionality in that it can display additional information about a site or circuit such as the equipment at the site, the contact person(s) for the site, and other useful information. Finally it can gather designated statistical information about a circuit and display it on demand.

MECHANISM
Xnetdb uses SNMP or ping to monitor things which its configured to monitor. It dynamically builds a network map on its display by querying entities and obtaining IP addresses and subnet masks. A configuration file tells xnetdb which IP hosts you want to monitor.

CAVEATS
While "ping" can be used to monitor hosts, more useful results are obtained using SNMP.

BUGS
Bugs and other assorted topics are discussed on the xnetdb mailing list. To join, send a note to "xnetdb-request@oar.net".

LIMITATIONS
None.

HARDWARE REQUIRED
No restrictions.

SOFTWARE REQUIRED
Most any variety of UNIX plus X-Windows and/or OpenWindows.

AVAILABILITY
Available via anonymous ftp from ftp.oar.net (currently 131.187.1.102) in the directory /pub/src. Special arrangements can be made for sites without direct IP access by sending a note to "xnetdb-request@oar.net". There are minimal licensing restrictions - these are detailed within the package.

Internet Tool Catalog XNETMON_WELLFLEET

NAME
xnetmon, xpmon

KEYWORDS
alarm, manager, map, status; IP; NMS, SNMP; UNIX.

ABSTRACT
Xnetmon and xpmon provide graphical representation of performance and status of SNMP-capable network ele ments. Xnetmon presents a schematic network map representing the up/down status of network elements; xpmon draws a pen plot style graph of the change over time of any arbitrary MIB object (RFC1066). Both xnet mon and xpmon use the SNMP (RFC1098) for retrieving status and performance data.

MECHANISM
Xnetmon polls network elements for the status of their interfaces on a controllable polling interval. Pop-up windows displaying the values of any MIB variable are supported by separate polls. When SNMP traps are received from a network element, that element and all adjacent elements are immediately re-polled to update their status. The layout of the network map is stati cally configured. Xpmon repeatedly polls (using SNMP) the designated network element for the value of the designated MIB variable on the user-specified interval. The change in the variable is then plotted on the strip chart. The strip chart regularly adjusts its scale to the current maximum value on the graph.

CAVEATS
Polling intervals should be chosen with care so as not to affect system performance adversely.

BUGS
None known.

LIMITATIONS
None reported.

HARDWARE REQUIRED
Distributed and supported for Sun-3 systems.

SPY An NFS monitoring/tracing tool

Availability:
A postscript file describing SPY is located on ftp.uu.net:/networking/ip/nfs/spy.ps.Z

NFSTRACE

This is the rpcspy/nfstrace package.

It is described in detail in the paper "NFS Tracing by Passive Network Monitoring", which appeared in the January, 1992 USENIX conference.

You'll need either a DEC machine running ULTRIX (with the packetfilter installed in the kernel) or a Sun running SunOS 4.x (with NIT). Or you'll need to do a bit of hacking.

The package differs slightly from the version in the paper:

- The handle- > name translation facility has been removed. It's just too fragile to include in the general release. If you need it, contact me directly and I'll be happy to mail you the code.

- The output format is a wee-bit different.

- The IBM-RT Enet filter version is also not included, since I seem to be the only person in the world running it. RTs are really too slow for this anyway.

To configure the package, edit the makefile in the obvious (to me at least) way.

Note that the not all versions of SunOS NIT have working versions of the packet timestamp mechanism. Try to set the -DSTAMPS option in the makefile, and if that doesn't work, take it out.

If you are actually going to use this to gather traces, I'd like to hear from you! Please send email, and share your results/traces if your organization will allow it. I maintain a mailing list of users for updates, etc. Send me mail to be added to it.


Happy tracing.

HOST

host - look up host names using domain server

SYNOPSIS
host [-v] [-a] [-t querytype] [options] name [server]
host [-v] [-a] [-t querytype] [options] -l domain [server]
host [-v] [options] -H [-D] [-E] [-G] domain
host [-v] [options] -C domain
host [-v] [options] -A host

DESCRIPTION
host looks for information about Internet hosts or domains. It gets this information from a set of interconnected servers that are spread across the world. By default, it simply converts between host names and Internet addresses. However, with the -t, -a and -v options, it can be used to find all of the information about hosts or domains that is maintained by the domain nameserver.

PINGs

Many many versions of the PING program exist. Each implementation has its own set of additional features. Here are a few more PINGs that are worth taking a look at.

Version on ftp.cc.berkeley.edu:pub/ping:
This version has duplicate packet detection, Record Route, ability to specify data pattern for packets, flood pinging, an interval option, Multicast support, etc.

Version on nikhefh.nikhef.nl:/pub/network/rping.tar.Z:
'rping' is just like 'ping', but only a single probe packet is sent to test the reachability of a destination. As an option, the loose source routing facility is used to show the roundtrip route the packet has taken. Multiple addresses of remote hosts are tried until one responds. As an option, each of multiple addresses can be probed unconditionally. Contains a patch for making loose source routing work in case you have a SUN with an OMNINET ethernet controller.

VRFY

vrfy.tar.Z (Version 921021)
'vrfy' is a tool to verify email addresses and mailing lists. In its simplest form it takes an address "user@domain", figures out the MX hosts for "domain", and issues the SMTP command VRFY at the primary MX host (optionally all), or at "domain" itself if no MX hosts exist. Without "domain" it goes to "localhost". More complex capabilities are: recursively expanding forward files or mailing lists, and detecting mail forwarding loops. Full-blown RFC822 address specifications are understood. Syntax checking can be carried out either locally or remotely. Various options are provided to exploit alternative protocol suites if necessary, and to print many forms of verbose output. Obvious limitations exist, but on average it works pretty well. Needless to say you need internet (nameserver and SMTP) access. See the man page and the extensive documentation in the source for further details.

XNETLOAD

NAME
xnetload - ethernet load average display for X

SYNOPSIS
xnetload[-toolkitoption ...] [-scale integer]
[-update seconds] [-hl color] [-highlight color]
[-jumpscroll pixels] [-label string] [-nolabel] host

DESCRIPTION
The xnetload program displays a periodically updating histo gram of the ethernet load average for the specified host. The resulting graph is scaled as 0% to 100%, where 0% corresponds to 0mbs and 100% corresponds to 10mbs. NOTE: The specified host must be running rpc.etherd.

This program has been run using X11R4 and X11R5, under the following operating systems:

SUNOS 4.1.0 SUNOS 4.1.1 ULTRIX V4.2 IRIX 3.3.2

Assuming the Imake templates and Rules are in order and in the proper place on your system, these programs should compile and link straightforward by running the following sequence:


xmkmf
make

Then, as root, issue the following:


make install
make install.man

Then, on your host system, (or on any other system you can rlogin or rsh into) start the etherd daemon with the following (must be root):

/usr/etc/rpc.etherd le0 &

where le0 is the mnemonic for the primary ethernet interface.

To start the xnetload program, the following command line is suggested:

./xnetload -hl red host &

where "host" is the name of any reachable network node (including LOCALHOST) that is running the etherd daemon. A small xload window should appear on your local display with nine horizontal lines. The label: "Ethernet Load %" should appear in the upper left hand corner, just below any additional title bars or other decorations provided by your window manager. If the program comes up without the nine lines, or without the "Ethernet Load" label, then either your resource file is not properly installed in the appropriate app-defaults directory, or you may have picked up the wrong xnetload image. Try re-running "make install" as root, or be sure to include the "./" in front of the command name.

Good Luck!

The following changes have been made to this directory since R3:

o Now use Athena StripChart widget.

o Understands WM_DELETE_WINDOW.

o 3-26-92 Modified from xload to xnetload by Roger Smith, Sterling Software at NASA-Ames Research Center, Mountain View, Calif. rsmith@proteus.arc.nasa.gov

NETTEST

nettest, nettestd - Performs client and server functions for timing data throughput

The nettest and nettestd commands invoke client and server programs that are used for timing data throughput of various methods of interprocess communication. For TCP and OSI con- nections, the nettest program establishes a connection with the nettestd program, and then it does count writes of size bytes, followed by count reads of size bytes. For UDP, the nettest program performs only writes; reads are not per formed. The nettestd program, if used with UDP connections, reads the data packets and prints a message for each data packet it receives. The number and size of the reads and writes may not correlate with the number and size of the actual data packets that are transferred; it depends on the protocol that is chosen. If you append an optional k (or K) to the size, count, or bufsize value, the number specified is multiplied by 1024.

This source for nettest and nettestd are provided on an "as is" basis. Cray Research does not provide any support for this code (unless you are a customer who has purchased the UNICOS operating system).

We will gladly take bug reports for nettest/nettestd. Suggested fixes are prefered to just bug reports. Changes to allow nettest/nettestd to run on other architectures are also welcomed. We will try to incorporate bugfixes and update the publicly available code, but we can make no guarantees.

Notes:


1) The -b option to nettestd has not been tested...
2) The ISO code should work on a 4.4BSD system, but the gethostinfo() routine is specific to UNICOS...

ETHERCK

etherck is a simple program that displays Sun ethernet statistics. If you have a high percents of input errors that are due to "out of buffers", then you can run the "iepatch" script to patch a kernel that uses the Intel ethernet chip ("ie"). A back of the envelope calculation shows that a .25% input error rate gives about a 10% degradation of NFS performance if 8k packets are being used.

In our environment at Legato, patching the ie buffer allocation made the input error rate drop more than 2 orders of magnitude. This was after we had applied other networking fixes (e.g., using Prestoserve, going from thin wire to twisted pair) and pushed a higher load on the server.

Note that both etherck and iepatch must be run by root (or you can make etherck setgid kmem).

Availability:
send EMAIL to: request@legato.com
with a Subject line: send unsupported etherck

The following is part of the 'help' file from the Legato Email Server:

This message comes to you from the request server at Legato.COM, request@Legato.COM. It received a message from you asking for help.

The request server is a mail-response program. That means that you mail it a request, and it mails back the response.

The request server is a very dumb program. It does not have much error checking. If you don't send it the commands that it understands, it will just answer "I don't understand you".

The request server has 4 commands. Each command must be the first word on a line. The request server reads your entire message before it does anything, so you can have several different commands in a single message. The request server treats the "Subject:" header line just like any other line of the message. You can use any combination of upper and lower case letters in the commands.

The request server's files are organized into a series of directories and subdirectories. Each directory has an index, and each subdirectory has an index. The top-level index gives you an overview of what is in the subdirectories, and the index for each subdirectory tells you what is in it.

The server has 4 commands:

"help" command: The command "help" or "send help" causes the server to send you the help file. You already know this, of course, because you are reading the help file. No other commands are honored in a message that asks for help (the server figures that you had better read the help message before you do anything else).

SEND a request to Legato to get the rest of the help file!

NETCK

netck is a shar file that contains the sources to build "netck", a network checker that uses the rstat(3R) protocol to gather and print statistics from machines on the network. netck is useful to help understand what part of what machines are potential NFS bottlenecks. To get this file, send email to the request server with the command "send unsupported netck".

Availability: same as ETHERCK (send email To: request@legato.com; subject: HELP)
