SNMP Sniff v1.0 allows you to decode any SNMPv[1,2]c packets that go through your network. It shows just about everything you need to know about the PDU, including errors, variable bindings, etc. It's a must as a sidekick for network management platforms. SNMP Sniff runs on Solaris and Linux. Other extra features are Community, PDU type, and OID filtering of packets and a simple Perl Curses user interface.
