Linux SNMP Network Management Tools
This page assumes that you already have a working knowledge of
the basic tools -- ping, netstat, traceroute,
nslookup, dig, tcpdump, /proc/net,
ipfwadmin, tcpwrapper, maskd
and are looking for graphical, distributed tools.
The following should also be consulted for additional leads:
To make the best use of the features of SNMP, a framework that
allows for easy configuration, web, pager and email notification,
and incorporates other traditional monitoring methods, is vital.
- The Mon
package provides a highly flexible framework for a large assortment
of monitors and alerts for system and network events. This may well
be the premier of the freeware packages.
PIKT is a general framework
for problem detection, software distribution, and automated problem
- Playin' in the LAN
- Playin' in the LAN
is a set of tools designed to allow hub/router status to be monitored,
including alarms, connectivity, traffic graphs, equipment inventory
and more. Data archiving via SQL.
- scotty, tkined
scotty is a set of tcl extensions designed for network
management. Tkined is a graphical application built on
scotty to do that management.
I am told that this is a powerful & complete system.
Kinetics from Loran Technologies is a turnkey network management
system. Bundle includes hardware and software; the base OS is
Linux. Not for the faint of wallet; pricing starts at $8300 for
a 1-150 station license & goes up from there. This product is aimed
at the high-end network management tools from IBM and HP.
- Big Brother
- The Big
Brother package provides web-based, multi-platform configurable
network/system/application/filesystem monitor. It can be configured
to call a pager when alarms occur.
The "Simple Network Management Protocol" (SNMP) is an internet
standard for gathering statistics from and managing devices on
the internet, principally routers. Below follows a list of free and
commercial network management tools for Linux.
Multi-Router Traffic Grapher is a magnificent graphing tool that
will create web pages showing hourly, daily, weekly and yearly
in-bound and out-bound packet traffic on one or many routers/ports.
Colorful, ease of installation is typical for a source-code package.
It runs automatically without a glitch. *Recommended*.
- SNMP Sniff
- SNMP Sniff
is an SNMP packet sniffer. It will listen to a network (LAN)
segment in promiscuous mode, and report and decode any information
that passes by in any SNMPv1 and SNMPv2 (Community Based) PDU.
This can be very useful for debugging new SNMP programs, diagnosing
bad interactions between agents and managers, as well as just
learning SNMP internals.
- NetSCARF Scion
- NetSCARF, the
Network Statistics Collection And Reporting Facility, performs
SNMP queries and displays results on the web.
- SNMP Vulture
- SNMP Vulture is a set of perl
scripts coupled to gnuplot and PBMPlus to create graphs and web pages.
Sources appear a bit stale (last updated October 1996).
- IBM Webbin
- IBM (Zurich) has
released a Linux port of its Webbin' CMIP (and SNMP) tools. This
tool is interesting because it creates web-pages on the fly, on a
special port number, and does not require you to configure or run
a web server. Installation is almost trivial. Output in VRML as
well as HTML. The next nice thing about this package is the
automatic discovery feature, which will locate all snmp agents on
your net. In other ways, this package is underwhelming: before you
know it, you're just browsing another MIB. No alarm support, no
graphs, no history. None-the-less, kudos to IBM for supporting the
Linux platform; this is worth a spin around the block.
- Cyber Professionals have
a web-based SNMP Network Management System, RMONX, which provide
a number of features: network status, event detection &
notification, trend monitoring, MIB browsing & configuration.
- The CMU-SNMP package is a set of basic, low-level libraries, utilities,
and of course the snmpd daemon. Most Linux distributions come
with this package by default, and include a special extended Linux MIB.
If you want to monitor/control a Linux box via SNMP, this package is a
must-have. See the
CMU-SNMP-3.2 availability announce (old).
- DevPatrol is a
simple set of Perl scripts that collect current and historical
information about host uptime & availability, presenting the
results as web pages. It uses SNMP queries, ICMP/UDP/TCP pings
and challenge/response on TCP ports to verify reachability &
availability of hosts and subsystems (daeomsn, such as POP3, www,

NetEye is a commercial product that provides a Motif-based network
management and trouble-ticketing system. It supports SNMP and a subset
of SNMPv2, handles alarms and events, and database integration.
screen shot looks interesting
... Unfortunately for English-speakers, the page is in Italian.
- WWW SNMP MIB Browser
WWW SNMP MIB Browser is a tcl script that allows you to browse
SNMP MIB entries with a web browser. Note however, that MIB's are very
low level constructs in SNMP -- this tool does NOT provide summary
information, graphs, etc. It simply presents a plain ASCII
display of the current values of the standard low-level info.
Worth a spin, though.
Netman Development Group
provides a set of tools for network management -- runs on UNIX's, I
was unable to find Linux binaries (the group mentions that a Linux port
has not yet been done). Their page shows some intriguing screen shots.
The university that sponsored this project wants $500 US for the source
provides a scripting language interface to a shell-like MIB browser.
The MIB browser shell supports "cd" and "ls" for walking the MIB
tree as if it were a file directory. Includes a built agent so that
scripts can be used to build custom agents.

- BTNG / tricklet
- BTNG appears to be an RMON and SNMPv1 ethernet packet monitor.
Tricklet seems to be a Tk/tcl based MIB browser.
Univ of Delft FTP
- The screen shots
look pretty intriguing. HNMS appears to be available on common
Linux ftp sites and cd-roms.
XNetDB is advertised as a graphical (X11 based) SNMP client,
but the sources appear to date to 1991. A quick attempt to compile on
Linux yielded naught ... a file called "sys/mbuf.h" is missing, together
with its definition of mbufBuf and MT_RTABLE. Not clear that anything
this old is worth pursuing... Sigh ...
- This is an SNMP application that polls routers/gateways for
packet traffic statistics. Generates plots with gnuplot.
Old, dates to 1992. Does not appear to
be currently maintained.
AARNet gwtraffic Home FTP Site.
The folks at
MimeStar, Inc offer
a network security tool that offers session logging and playback,
session hijacking, and dynamic firewalling. This tool can be used for
tracking malicious users/hackers, as well as for remote network
consulting and diagnostics.
