Network Working Group R. Stine, Editor Request for Comments: 1147 SPARTA, Inc. FYI: 2 April 1990 FYI on a Network Management Tool Catalog: Tools for Monitoring and Debugging TCP/IP Internets and Interconnected Devices Status of this Memo The goal of this FYI memo is to provide practical informa- tion to site administrators and network managers. This memo provides information for the Internet community. It does not specify any standard. It is not a statement of IAB pol- icy or recommendations. Comments, critiques, and new or updated tool descriptions are welcome, and should be sent to Robert Stine, at stine@sparta.com, or to the NOCTools work- ing group, at noctools@merit.edu. Distribution of this memo is unlimited. 1. Introduction This catalog contains descriptions of several tools avail- able to assist network managers in debugging and maintaining TCP/IP internets and interconnected communications resources. Entries in the catalog tell what a tool does, how it works, and how it can be obtained. The NOCTools Working Group of the Internet Engineering Task Force (IETF) compiled this catalog in 1989. Future editions will be produced as IETF members become aware of tools that should be included, and of deficiencies or inaccuracies. Developing an edition oriented to the OSI protocol suite is also contemplated. 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 pro- vided by vendors. Caveat Emptor. 1.1 Purpose The practice of re-inventing the wheel seems endemic to the field of data communications. The primary goal of this IETF NOCTools Working Group [Page 1] RFC 1147 FYI: Network Management Tool Catalog April 1990 document is to fight that tendency in a small but useful way. By listing the capabilities of some of the available network management tools, we hope to pool and share knowledge and experience. Another goal of this catalog is to show those new in the field what can be done to manage internet sites. A network management tutorial at the end of the document is of further assistance in this area. Finally, by omission, this catalog points out the network management tools that are needed, but do not yet exist. There are other sources of information on available network management tools. Both the DDN Protocol Implementation and Vendors Guide and the DATAPRO series on data communications and LANs are particularly comprehensive and informative. The DDN Protocol Implementation and Vendors Guide addresses a wide range of internet management topics, including evaluations of protocol implementations and network analyzers.* The DATAPRO volumes, though expensive (check your local university or technical libraries!), are good surveys of available commercial products for network manage- ment. DATAPRO also includes tutorials, market analyses, product evaluations, and predictions on technology trends. 1.2 Scope The tools described in this document are used for managing the network resources, LANs, and devices that are commonly interconnected by TCP/IP internets. This document is not, however, a "how to" manual on network management. While it includes a tutorial, the coverage is much too brief and gen- eral to serve as a sole source: a great deal of further study is required of aspiring network managers. Neither is this catalog is an operations manual for particular tools. Each individual tool entry is brief, and emphasizes the uses to which a tool can be put. A tool's documentation, which in some cases runs to hundreds of pages, should be consulted for assistance in its installation and operation. 1.3 Overview Section 1 describes the purpose, scope, and organization of this catalog. Section 2 lists and explains the standard keywords used in _________________________ * Instructions for obtaining the DDN Protocol Guide are given in Section 7 of the appendix. IETF NOCTools Working Group [Page 2] RFC 1147 FYI: Network Management Tool Catalog April 1990 the tool descriptions. The keywords can be used as a sub- ject index into the catalog. Section 3, the main body of the catalog, contains the entries describing network management tools. The tool entries in Section 3 are presented in alphabetical order, by tool name. The tool descriptions all follow a standard for- mat, described in the introduction to Section 3. Following the catalog, there is an appendix that contains a tutorial on the goals and practice of network management. 1.4 Acknowledgements The compilation and editing of this catalog was sponsored by the Defense Communications Engineering Center (DCEC), con- tract DCA100-89-C-0001. The effort grew out of an initial task to survey current internet management tools. The cata- log is largely, however, the result of volunteer labor on the part of the NOCTools Working Group, the User Services Working Group, and many others. Without these volunteer contributions, the catalog would not exist. The support from the Internet community for this endeavor has been extremely gratifying. Several individuals made especially notable contributions. Mike Patton, Paul Holbrook, Mark Fedor and Gary Malkin were particularly helpful in composition and editorial review, while Dave Crocker provided essential guidance and encouragement. Bob Enger was active from the first with the gut work of chairing the Working Group and building the catalog. Phill Gross helped to christen the NOCTools Work- ing Group, to define its scope and goals, and to establish its role in the IETF. Mike Little contributed the formative idea of enhancing and publicizing the management tool survey through IETF participation. Responsibility for any deficiencies and errors remains, of course, with the editor. IETF NOCTools Working Group [Page 3] RFC 1147 FYI: Network Management Tool Catalog April 1990 2. 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 key- word definitions have been developed, and are given below. Following the definitions, there is an index of catalog entries by keyword. 2.1 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: o+ the general management area to which a tool relates or a tool's functional role; o+ the network resources or components that are managed; o+ the mechanisms or methods a tool uses to perform its functions; o+ the operating system and hardware environment of a tool; and o+ the characteristics of a tool as a hardware pro- duct or software release. 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. Analyzer a traffic monitor that reconstructs and interprets pro- tocol messages that span several packets. Benchmark a tool used to evaluate the performance of network com- ponents.

UNIX a tool that runs under 4.xBSD UNIX or related OS. VMS a tool that runs under DEC's VMS operating system. The keywords used to describe a tool's characteristics as a hardware or software acquisition are: Free a tool is available at no charge, though other restric- tions may apply (tools that are part of an OS distribu- tion but not otherwise available are not listed as "free"). Library a tool packaged with either an Application Programming Interface (API) or object-level subroutines that may be loaded with programs. Sourcelib a collection of source code (subroutines) upon which developers may construct other tools. IETF NOCTools Working Group [Page 8] RFC 1147 FYI: Network Management Tool Catalog April 1990 2.2 Tools Indexed by Keywords Following is an index of catalog entries sorted by keyword. This index can be used to locate the tools with a particular attribute: tools are listed under each keyword that charac- terizes them. The keywords and the subordinate lists of tools under them are in alphabetical order. In the interest of brevity, some liberties have been taken with tool names. Capitalization of the names is as speci- fied by the tool developers or distributers. Note that parenthetical roman numerals following a tool's name are not actually part of the name. The use of roman numerals to differentiate tools with the same name is explained in the introduction of Section 3. alarm bridge CMIP Library ConnectVIEW EtherMeter decaddrs LanProbe NMC LANWatch proxyd NETMON (III) Snmp Libraries osilog snmpd SERAG sma Snmp Libraries CHAOS snmptrapd LANWatch SpiderMonitor map Unisys NCC WIN/MGT Station xnetmon (I) control XNETMON (II) CMIP Library ConnectVIEW NETMON (III) analyzer NMC LANWatch proxyd Sniffer Snmp Libraries SpiderMonitor snmpset TokenVIEW Unisys NCC benchmark WIN/MGT Station hammer XNETMON (II) nhfsstone SPIMS spray TTCP Unisys NCC IETF NOCTools Working Group [Page 9] RFC 1147 FYI: Network Management Tool Catalog April 1990 curses DOS Internet Rover Comp.

Tool Descriptions This section is a collection of brief descriptions of tools for managing TCP/IP internets. These entries are in alpha- betical 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. We deal with the problem of tool-name clashes -- different tools that have the same name -- by appending parenthetical roman numerals to the names. For example, BYU, MITRE, and SNMP Research each submitted a description of a tool called "NETMON." These tools were independently developed, are functionally different, run in different environments, and are no more related than Richard Burton the 19th century explorer and Richard Burton the 20th century actor. BYU's tool "NETMON" is listed as "NETMON (I)," MITRE's as "NETMON (II)," and the tool from SNMP Research as "NETMON (III)." The parenthetical roman numerals reveal only the order in which the catalog editor received the tool descriptions. They should not be construed to indicate any sort of prefer- ence, priority, or rights to a tool name.

IETF NOCTools Working Group [Page 24] Internet Tool Catalog COMPUTER SECURITY CHECKLIST NAME Computer Security Checklist KEYWORDS security; DOS. ABSTRACT This program consists of 858 computer security ques- tions divided up in thirteen sections. The program presents the questions to the user and records their responses. After answering the questions in one of the thirteen sections, the user can generate a report from the questions and the user's answers. The thirteen sections are: telecommunications security, physical access security, personnel security, systems develop- ment security, security awareness and training prac- tices, organizational and management security, data and program security, processing and operations security, ergonomics and error prevention, environmental secu- rity, and backup and recovery security. The questions are weighted as to their importance, and the report generator can sort the questions by weight. This way the most important issues can be tackled first. MECHANISM The questions are displayed on the screen and the user is prompted for a single keystroke reply. When the end of one of the thirteen sections is reached, the answers are written to a disk file. The question file and the answer file are merged to create the report file. CAVEATS None. BUGS None known. LIMITATIONS None reported. HARDWARE REQUIRED No restrictions. SOFTWARE REQUIRED DOS operating system.

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 None. BUGS None known. LIMITATIONS None reported. HARDWARE REQUIRED Distributed and supported for Sun 3 systems. SOFTWARE REQUIRED Distributed and supported for SunOS 3.5 and 4.x.

IETF NOCTools Working Group [Page 30] Internet Tool Catalog DUAL MANAGER NAME Dual Manager KEYWORDS alarm, control, manager, map, security, status; IP, OSI; NMS, SNMP, X; UNIX; library. ABSTRACT Netlabs' Dual Manager provides management of TCP/IP networks using both SNMP and CMOT protocols. Such management can be initiated either through the X- Windows user interface (both Motif and Openlook), or through OSI Network Management (CMIP) commands. The Dual Manager provides for configuration, fault, secu- rity and performance management. It provides extensive map management features, including scanned maps in the background. It provides simple mechanisms to extend the MIB and assign specific lists of objects to specific network elements, thereby providing for the management of all vendors' specific MIB extensions. It provides an optional relational DBMS for storing and retrieving MIB and alarm information. Finally, the Dual Manager is an open platform, in that it provides several Application Programming Interfaces (APIs) for users to extend the functionality of the Dual Manager. The Dual Manager is expected to work as a TCP/IP "branch manager" under DEC's EMA, AT&T's UNMA and other OSI-conformant enterprise management architectures. MECHANISM The Netlabs Dual Manager supports the control and moni- toring of network resources by use of both CMOT and SNMP message exchanges. CAVEATS None. BUGS None known. LIMITATIONS None reported. HARDWARE REQUIRED Runs on Sun/3 and Sun/4s. IETF NOCTools Working Group [Page 31] Internet Tool Catalog DUAL MANAGER SOFTWARE REQUIRED Available on System V or SCO Open Desktop environments. Uses X-Windows for the user interface.

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. IETF NOCTools Working Group [Page 33] Internet Tool Catalog ENTM 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.

Box 808; L-561 Livermore, CA 94550 Phone : (415) 422-8266 E-Mail: sturtevant@ccc.nmfecc.gov 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.

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 SunOS.

IETF NOCTools Working Group [Page 36] Internet Tool Catalog ETHERHOSTPROBE NAME etherhostprobe KEYWORDS map, routing; ethernet, IP; ping; UNIX; free. ABSTRACT Output list of hosts on an ethernet that respond to IP ARP. Produces a list in the following format: 08:00:20:01:96:62 128.18.4.114 apptek4 08:00:20:00:02:fe 128.18.4.115 apptek5 08:00:20:00:57:6a 128.18.4.116 apptek6 08:00:20:00:65:34 128.18.4.117 apptek7 08:00:20:06:58:6f 128.18.4.118 apptek8 08:00:20:00:03:4f 128.18.4.119 apptek9 The first column is the ethernet address, the second the IP address, and the third is the hostname (which is omitted if the name could not be found via gethost- byaddr). A starting and ending IP address may be specified on the command line, which will limit the search. MECHANISM Etherhostprobe sends a UDP packet to the ``echo'' port, then looks in the kernel's ARP cache for the corresponding address entry. Explicit response (or lack of same) to the UDP packet is ignored. The cache will be checked up to four times at one-quarter-second intervals. Note that this allows the program to be run by a user with no special privileges. CAVEATS Etherhostprobe will fill the kernel's ARP cache with possibly useless entries, possibly causing delays to programs foolishly attempting to accomplish real work. Etherhostprobe causes -lots- of ARPs to be generated, possibly fooling network monitoring software (or peo- ple) into concluding that something is horribly broken. Etherhostprobe spends up to one second looking for each possible address. Thus, exhaustively searching a class-C network will take about four minutes, and exhaustively searching a class-B network will take about 18 hours. Exhaustively searching a class-A net- work will take the better part of a year, so don't even IETF NOCTools Working Group [Page 37] Internet Tool Catalog ETHERHOSTPROBE think about it. Etherhostprobe will be fooled by gateways that imple- ment proxy ARP; every possible address on the proxy- ARPed subnet will be listed with the gateway's ethernet address. BUGS None known. LIMITATIONS If a given machine is not running IP ARP at the time that it is probed, it will be considered nonexistent. In particular, if a given machine is down at the time that it is probed . . . All hosts being probed must be on the same (possibly bridged) ethernet. HARDWARE REQUIRED No restrictions, but see below. SOFTWARE REQUIRED Runs on SunOS 3.5, and possibly elsewhere. The major non-standard portion of code is ``tx_arp.c'', which reads the kernel's ARP cache. AVAILABILITY Copyrighted, but freely distributed.

IETF NOCTools Working Group [Page 38] Internet Tool Catalog ETHERMETER NAME EtherMeter (tm), model LANB/150 KEYWORDS alarm, map, traffic; ethernet; NMS, proprietary; stan- dalone. ABSTRACT The Network Applications Technology (NAT) EtherMeter product is a dedicated ethernet traffic monitor that provides statistics on the ethernet segment to which it is attached. The EtherMeter reports three major kinds of statistics. For good packets, it reports the total number of good packets seen on the segment, the number of multicast and broadcast packets, and the total number of bytes in all packets seen. For packets with errors, it reports the number of CRC errors, short packets, oversize packets, and alignment errors. It also reports the distribution of packet by type, and the number of protocols seen on the segment. A count of transmit collisions is reported. Peak and current ethernet utilization rates are also reported, etc. Alarms can be set for utilization rate, packet rate, total error count, and delta error. The EtherMeter reports the statistics to a Network Management Station (NMS), also available from NAT, via IP/UDP datagrams, so that the meters can be monitored through routers. The NMS displays graphical and/or textual information, and EtherMeter icons turn colors to indicate status. Alarms can be set, and if the lev- els are exceeded an audible alarm is generated on the NMS, and the EtherMeter icon changes from green to yel- low on the network map. MECHANISM The EtherMeter is a self-contained board that can either be plugged into a PC/AT bus for power or installed in a small stand-alone enclosure. The board can be obtained with either a 10BASE5 thick ethernet transceiver cable connector, or a 10BASE2 thin ethernet BNC connector. CAVEATS The EtherMeter is primarily a passive device whose only impact on the network will come from the monitoring packets sent to the NMS. The EtherMeter is assigned an IP address for communication with the NMS. IETF NOCTools Working Group [Page 39] Internet Tool Catalog ETHERMETER BUGS None known. LIMITATIONS Proprietary protocol currently in use. The company has stated its intention to develop SNMP for the EtherMeter product in the first half of 1990. Currently the NMS does not keep log files. This limitation is ack- nowledged, and plans are underway to add ASCII log file capability to the NMS. HARDWARE REQUIRED An EtherMeter board and a PC/AT bus to plug it into, or a stand-alone enclosure with power supply (available from NAT). A Network Management Station and its software is required as well, to fully interact with the EtherMeter devices. SOFTWARE REQUIRED The EtherMeter software is included in ROM on the dev- ice. The NMS software is bundled in with the NMS hardware.

ABSTRACT EtherView is a network monitoring tool which runs on Sun workstations and allows you to monitor your hetero- geneous internet network. It monitors all systems on the ethernet. It has three primary functions: Load Profile: It allows users to monitor the load on the ethernet over extended periods of time. The net- work administrator can use it to characterize load gen- erated by a node on the network, determine which sys- tems and applications generate how much of the load and how that load fluctuates over long periods of time. NFS Profile: It allows the network administrator to determine the load on NFS servers, the average response time NFS servers and the mix of NFS load on each of the servers. Users can use the data to benchmark different NFS servers, determine which servers are overloaded, deduce the number of clients that each server can sup- port and evaluate the effectiveness of NFS accelera- tors. Protocol Analyzer: Users can capture packets based on source, destination, application, protocol, bit pat- tern, packet size or a boolean filtering expression. It provides all standard features such as configurable buffer size, packet slicing and bit pattern based triggering criterion. It does automatic disassembly of NFS, TCP, UDP, IP, ICMP, ARP and RARP packets. Packets can be examined in any combination of summary, hex or detail format. MECHANISM EtherView uses the Sun's NIT interface to turn the eth- ernet interface into promiscuous mode to capture pack- ets. A high level process manages the interface and a low level process does the actual capturing and filter- ing. Shared memory is used to communicate between the two processes. BUGS None known. IETF NOCTools Working Group [Page 41] Internet Tool Catalog ETHERVIEW LIMITATIONS Because of limitations in Sun's NIT interface, Ether- View will not capture packets originating from the sys- tem where it is run. EtherView requires super-user privileges on the system where it is run. HARDWARE REQUIRED EtherView runs on all models of Sun-3, Sun-4 and Sun- 386i. SOFTWARE REQUIRED Sun-3 - SunOS 4.0.3. (SunOS 4.0 with NIT fixes). Sun-4 - SunOS 4.0. Sun-386i - SunOS 4.0. Runs under SunView. Will run under X Windows in future.

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 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).

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. LIMITATIONS Host table required.

The tree structure of the MIB is presented graphically, and the user traverses the tree by select- ing branches of the tree. When the MIB variables are displayed, selecting them causes a text window to appear and show the definition of that variable (using the actual text of the MIB document). MECHANISM The Apple Macintosh HyperCard utility is used. The actual text of the MIB document is read into scrollable text windows, and a string search is done on the vari- able selected. A person familiar with HyperCard pro- gramming could modify the program to suit their needs (such as to add the definitions for their company's private space). CAVEATS None. BUGS None known.

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. IETF NOCTools Working Group [Page 50] Internet Tool Catalog INTERNET ROVER LIMITATIONS This tools 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.

ABSTRACT 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.

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. IETF NOCTools Working Group [Page 54] Internet Tool Catalog LANPROBE 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.

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 IETF NOCTools Working Group [Page 56] Internet Tool Catalog LANWATCH 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.

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.

The SNMP has been benchmarked at 200 Management Operations per Second (MOPS) for a 1- MIPS machine. MECHANISM The Netlabs SNMP agent supports the control and moni- toring of network resources by use of SNMP message exchanges. CAVEATS None. BUGS None known. LIMITATIONS None reported. HARDWARE REQUIRED Portable to most hardware. SOFTWARE REQUIRED Portable to most operating systems.

ABSTRACT Netmon is a DOS-based program that pings hosts on a monitored list at user-specified intervals. In addi- tion, a user may optionally ping hosts not on the list. Netmon also performs domain lookups. Furthermore, a user may build and send a domain query to any desired DNS server. MECHANISM The tool works by using the echo service feature of ICMP. It reports if it receives an incorrect response or no response. CAVEATS Depending on the frequency of pinging and the number of hosts pinged, netmon could create a high volume of traffic. BUGS None known. LIMITATIONS None reported. HARDWARE REQUIRED A PC, and a Western Digital WD8003 interface card (or any other card for which there is a packet driver for FTP Software Inc.'s PC/TCP kernel). Both monochrome and color displays are supported, though color is recommended. SOFTWARE REQUIRED DOS operating system, and the PC/TCP Kernel by FTP Software, Inc. AVAILABILITY The BYU modified version is available for anonymous FTP from Dcsprod.byu.edu, in directory "programs." It can be freely distributed for non-commercial use. IETF NOCTools Working Group [Page 63] Internet Tool Catalog NETMON (II) 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 IETF NOCTools Working Group [Page 64] Internet Tool Catalog NETMON (II) 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.

IETF NOCTools Working Group [Page 66] Internet Tool Catalog NETMON (III) NAME NETMON -- an SNMP-based network management tool from SNMP Research. KEYWORDS alarm, control, manager, map, routing; DECnet, ether- net, IP, OSI, ring, star; NMS, SNMP; DOS; sourcelib. ABSTRACT The NETMON application implements a network management station based on a low-cost DOS-based platform. It can be successfully used with many types of networks, including both wide area networks and those based on various LAN media. NETMON has been used with multipro- tocol devices including those which support TCP/IP, DECnet, and OSI protocols. The fault management tool displays the map of the network configuration with current node and link state indicated in one of several colors. Alarms may be enabled to alert the operator of events occurring in the network. Events are logged to disk. The NETMON application comes complete with source code including a powerful set of portable libraries for generating and parsing SNMP messages. Output data from NETMON may be transferred via flat files for additional report generation by a variety of statistical packages. MECHANISM The NETMON application is based on the Simple Network Management Protocol (SNMP). Polling is performed via the powerful SNMP get-next operator and the SNMP get operator. Trap directed polling is used to regulate the focus and intensity of the polling. CAVEATS None. BUGS None known. LIMITATIONS The monitored and managed nodes must implement the SNMP over UDP per RFC 1098 or must be reachable via a proxy agent. HARDWARE REQUIRED The minimum system is a IBM Personal Computer (4.77 MHz) with DOS 3.0 or later, an Enhanced Graphics IETF NOCTools Working Group [Page 67] Internet Tool Catalog NETMON (III) Adapter, Enhanced Graphics Monitor, a single 360 Kbyte floppy drive, and an ethernet adapter. However, most users will find a hard disk to be helpful for storing network history and will be less impatient with a fas- ter CPU. SOFTWARE REQUIRED DOS 3.0 or later and TCP/IP software from one of several sources. AVAILABILITY This is a commercial product available under license from: SNMP Research P.O.

ABSTRACT Netstat is a program that accesses network related data structures within the kernel, then provides an ASCII format at the terminal. Netstat can provide reports on the routing table, TCP connections, TCP and UDP "listens", and protocol memory management. 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.

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. IETF NOCTools Working Group [Page 69] Internet Tool Catalog NETWATCH NAME netwatch KEYWORDS traffic; ethernet, IP, ring; eavesdrop; DOS; free. ABSTRACT PC/netwatch listens to an attached local broadcast net- work and displays one line of information for every packet that goes by. This information consists of the "to" and "from" local network addresses, the packet length, the value of the protocol type field, and 8 selected contiguous bytes of the packet contents. While netwatch is running it will respond to commands to display collected information, change its operating mode, or to filter for specific types of packets. MECHANISM Puts controller in promiscuous mode. CAVEATS None. BUGS None known. LIMITATIONS The monitor can handle a burst rate of about 200 pack- ets per second. Packets arriving faster than that are missed (but counted in the statistics of the network driver). The display rate is about 25 packets per second and there is a buffer that can hold 512 undisplayed packets. The monitor discards overflow packets. HARDWARE REQUIRED IBM PC compatible with CGA and network interface (3com 3C501, Interlan NI5010, or proNet p1300). SOFTWARE REQUIRED DOS 2.0 or higher, MicroSoft C (to generate custom exe- cutables) IETF NOCTools Working Group [Page 70] Internet Tool Catalog NETWATCH AVAILABILITY Available as a utility program in the pcip distribution from host husc6.harvard.edu, in directory pub/pcip.

IETF NOCTools Working Group [Page 71] Internet Tool Catalog NETWORK INTEGRATOR I 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. IETF NOCTools Working Group [Page 72] Internet Tool Catalog NETWORK INTEGRATOR I SOFTWARE REQUIRED 4.0BSD UNIX or greater, or related OS.

IETF NOCTools Working Group [Page 73] 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. IETF NOCTools Working Group [Page 74] Internet Tool Catalog NET_MONITOR 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.
