ABSTRACT
The 9100 Network Management Center provides the capa-
bility to manage and control standards-based networking
products from Hughes LAN Systems' and other vendors.
This management extends to all network products that
are equipped with the industry standard SNMP (Simple
Network Management Protocol). A comprehensive rela-
tional database manages the data and ensures easy
access and control of resources throughout the network.
9100 NMC software provides the following functions:
Database Management
Stores and retrieves the information required to
administer and configure the network. It can be
used to:
Store and recall configuration data for all
devices.
Provide availability history for devices.

Provide administrative information such as
physical location of devices, person respon-
sible, maintenance history, asset data,
hardware/software versions, etc.
Configuration Management
A comprehensive configuration model that enables
you to:
Retrieve configuration information from SNMP
devices.
Configure HLS devices using SNMP.
Configures attributes relating to TCP/IP,
DECnet and other protocols in HLS devices
using SNMP.
Poll devices to compare their current attri-
bute values with those in the database and
produce reports of the discrepancies.
Collect data about the state of the network.
Performance Management
Displays local network traffic graphically, by
packet size, protocol, network utilization,
sources and destinations of packets, etc.
Fault Management

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.

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.

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.

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

NAME
ping
KEYWORDS
generator, status; IP; ping; DOS, UNIX, VMS; free.
ABSTRACT
Ping is perhaps the most basic tool for internet
management. It verifies that a remote IP implementa-
tion and the intervening networks and interfaces are
functional. It can be used to measure round trip
delay. Numerous versions of the ping program exist.
MECHANISM

loads.
BUGS
None known.
LIMITATIONS
PC/TCP's ping is the only implementation known support
both loose and strict source routing. Though some ping
implementations support the ICMP "record route"
feature, the usefulness of this option for debugging
routes is limited by the fact that many gateways do not
correctly implement it.
HARDWARE REQUIRED

NAME
proxyd -- SNMP proxy agent daemons from SNMP Research.
KEYWORDS
control, status; bridge, ethernet, IP, ring, star; NMS,
SNMP; UNIX; library, sourcelib.
ABSTRACT
SNMP proxy agents may be used to permit the monitoring
and controlling of network elements which are otherwise
not addressable using the SNMP management protocol
(e.g., a network bridge that implements a proprietary
management protocol). Similarly, SNMP proxy agents may
be used to protect SNMP agents from redundant network
management agents through the use of caches. Finally,
SNMP proxy agents may be used to implement elaborate
MIB access policies. The proxy agent daemon listens
for SNMP queries and commands from logically remote
network management stations, translates and retransmits
those as appropriate network management queries or
cache lookups, listens for and parses the responses,
translates the responses into SNMP responses, and
returns those responses as SNMP messages to the network
management station that originated the transaction.
The proxy agent daemon also emits SNMP traps to identi-
fied trap receivers. The proxy agent daemon is archi-
tected to make the addition of additional vendor-
specific variables a straight-forward task. The proxy
application comes complete with source code including a
powerful set of portable libraries for generating and
parsing SNMP messages and a set of command line utili-
ties.
MECHANISM
Network management variables are made available for
inspection and/or alteration by means of the Simple
Network Management Protocol (SNMP).
CAVEATS
None.
BUGS
None known.
LIMITATIONS
This application is a template for proxy application
writers.
Only a few of the many LanBridge 100 variables are sup-
ported.

NAME
SERAG -- the Simple Event Reporting and Alarm Genera-
tion tool
KEYWORDS
alarm, security; ethernet, IP; NMS, proprietary; UNIX.
ABSTRACT
The Simple Event Reporting and Alarm Generation (SERAG)
collects error messages and other event reports from
servers on a LAN. Any node with UDP/IP can be the
source of such messages/reports. The logging of error
messages is integrated with the audit trail facility of
the Network Control Server (NCS) from 3COM. Alarms are
generated on the NCS based on predefined conditions.
Alarms may be sent to the console of the NCS, logged in
a file, or routed via WAN to a service center.
SERAG can automatically detect a predefined set of
errors in the servers and generate alarms. The break-
down of a server in the LAN may also result in alarm
generation.
SERAG creates an error log that can be used for post-
testing analysis.
MECHANISM
The tool searches through the audit trail (error log)
files for events specified by the user. The search may
be constrained to specific nodes in the network and to
a specific time frame. Events may be combined into
conditions which are logical expressions (e.g., look
for eventA and eventB and not eventC within time frame
so and so). This is an interactive query facility to
analyze the audit trail (error log).
The user may also ask for such conditions to be checked
at regular intervals, and specify routing of error mes-
sages in case the condition is satisfied. The checking
of such conditions is done by a daemon process running
in the background.
CAVEATS
May impact the performance of the NCS if error logs are
big, or if conditions are computationally complex.
BUGS
None known.
LIMITATIONS
None reported.
HARDWARE REQUIRED
A workstation running UNIX.
SOFTWARE REQUIRED
Implemented in C (using lex and yacc) on a Sun 3/50.
Also runs under Xenix. Should work with most versions

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.

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.

NAME
Snmp Libraries and Utilities from SNMP Research.
KEYWORDS
alarm, control, manager, map, routing, status; bridge,
DECnet, ethernet, 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 genera-
tion 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 vari-
ables, retrieving tables, or effecting commands via the
setting of remote network management variables.

NAME
snmpask
KEYWORDS
manager, status; IP; NMS, SNMP; UNIX.
ABSTRACT
Snmpask is a network monitoring application which gath-
ers specific information from a single network entity
at regular intervals and stores this information into
UNIX flat files. A report generation package is
included in the NYSERNet SNMP Software Distribution to
produce reports and graphs from the raw data.
MECHANISM
Snmpask uses SNMP to gather its information. The agent
which must be queried and the variables to query for
are specified in a configuration file.
CAVEATS
An SNMP agent must be running in the network entity
being monitored in order for snmpask to be useful.
BUGS
None outstanding. They are fixed as reports come in.
Report bugs to: nysersnmp@nisc.nyser.net
LIMITATIONS
SNMP polling is done synchronously. Only a single
agent can be polled per snmpask process. Only 16 vari-
ables can be requested per snmpask process.
HARDWARE REQUIRED
Developed on Sun 3/60, Sun 3/260, tested on a SPARCsta-
tion I, DECstation, and a Solbourne 4/802.

ABSTRACT
Snmpd is an SNMP agent which runs on UNIX derivatives
and answers network management queries from network
management stations supporting SNMP. Snmpd also sup-
ports the sending of SNMP traps.
MECHANISM
Snmpd conforms to SNMP as specified in RFC 1098. Cer-
tain user configurable options are manipulated through
a simple configuration file.
CAVEATS
UNIX does not support all of the MIB variables speci-
fied in RFC 1066. Snmpd does the best it can to find
the answers.
BUGS
None outstanding. They are fixed as reports come in.

NAME
snmpd -- an SNMP host/gateway agent daemon from SNMP
Research.
KEYWORDS
manager, status; bridge, ethernet, IP, ring, star; NMS,
SNMP; DOS, UNIX; sourcelib.
ABSTRACT
The snmpd agent daemon listens for and responds to net-
work management queries and commands from logically
remote network management stations. The agent daemon
also emits SNMP traps to identified trap receivers.
The agent daemon is architected to make the addition of
additional vendor-specific variables a straight-forward
task. The snmpd application comes complete with source
code including a powerful set of portable libraries for
generating and parsing SNMP messages and a set of com-
mand line utilities.
MECHANISM
Network management variables are made available for
inspection and/or alteration by means of the Simple
Network Management Protocol (SNMP).
CAVEATS
None.
BUGS
None known.
LIMITATIONS
Only the operating system variables available without
source code modifications to the operating system and
device device drivers are supported.
HARDWARE REQUIRED
This software has been ported to a wide range of sys-
tems, too numerous to itemize. It includes worksta-
tions, general purpose timesharing systems, and embed-
ded hardware in intelligent network devices such as
repeaters, bridges, and routers.
