SNMPWALK is one of the main tools used by a network engineer to troubleshoot behavior or verify configuration of devices. The output however is pretty hard to understand. In this article, we will talk about how Unbrowse SNMP makes the task of working with SNMPWALK dumps much easier.Snmpwalk is a command line utility available on almost all router platforms. A standalone version is also available for free from the excellent Net-SNMP project.

An add-on tool for complete IAX2 (Asterisk Protocol) call analysis Click for Whitepaper "IAX2 Call Analyzer for Unsniff" (900 kb) Are you one of the growing number of people deploying the Asterisk VoIP platform ? We present a add-on tool that performs complete VoIP Call Analysis for the Inter Asterisk Exchange (IAX2) protocol. Measure and plot call bandwidth, interarrival delay, jitter, packet loss, and IAX2 events for each direction of call. This tool like others in this series (such as TCP/IP analysis) is written in the excellent Ruby scripting language using the Fox-Ruby toolkit. Full source code of the tool is provided for you to tweak it to your liking. If you are working with Asterisk in any capacity, this is a "must have" tool on your workbench.
Find out how you can use Unsniff to develop, debug, or test the IAX2 protocol (the native protocol used by the Asterisk open source PBX). Are you getting disconnected or the wrong codec is being negotiated ? Unsniff can help you debug it. Just hover your mouse over any field for bubble help to pinpoint your problem. You can track calls, playback each direction of a conversation, or save these conversations to a WAV file. If you know a scripting language (VBScript or Ruby) you can easily whip up your own analysis scripts.
Unsniff provides excellent support for SNMPv3
analysis such as deep
decodes, full bubble help, scriptability, and OID resolution.
However SNMPv3 in privacy mode will stump Unsniff because of its
encrypted payload. This article explains how you can continue to
analyze SNMPv3 using the decryption features provided by Unsniff. By
providing Unsniff with the privacy key information, you can
automatically decrypt SNMPv3 PDUs which use the CBC-DES and CFB-AES-128
symmetric encyption algorithms.
