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.

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.

Internet Tool Catalog NSLOOKUP
NAME
nslookup
KEYWORDS
status; DNS, BIND; UNIX, VMS; free.
ABSTRACT
Nslookup is an interactive program for querying
Internet Domain Name System (DNS) servers. It is
essentially a user-friendly front end to
the BIND "resolver" library 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

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.

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
identified trap receivers. The proxy agent daemon is
designed 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 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
This application is a template for proxy application
writers.

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.

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

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

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.
HARDWARE REQUIRED
PX20s are self contained, the KX20s require an IBM
PC/XT-AT compatible machine with 5 megabytes of hard
disk storage and the spare slot into which the board
kit is plugged.
SOFTWARE REQUIRED
None. The SpiderAnalyzer requires the Microsoft 'C'
Compiler, Version 5.0 for writing user defined decodes.
AVAILABILITY
The SpiderMonitor/Analyzer is available commercially.

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.

protocols, see:
