Linux SNMP MIB Browser

An SNMP MIB browser is an indispensable tool for engineers and system administrators to manage SNMP enabled network devices such as routers, switches, servers and workstations. The information provided by SNMP includes uptime, interface traffic data, routing information, TCP and UDP connection information, installed software, and much more.

In this tutorial, I introduce qtmib, an easy-to-use SNMP browser available for Linux and published under GPLv2 license. The program is build as a front-end for net-snmp tools using QT4 library.

Installing net-snmp MIBs on Ubuntu and Debian

Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing devices on IP networks. net-snmp is the main SNMP implementation for Linux and BSD platforms. On Ubuntu or Debian net-snmp tools are installed as follows:

$ sudo apt-get install snmp

You can also install snmpd package. This package contains the SNMP agent.

Installing MIBs

For licensing reasons, net-snmp package installs only a small number of MIBs in /usr/share/mibs directory. A large number of standard MIBs can be installed using snmp-mibs-downloader package:

$ sudo apt-get install snmp-mibs-downloader
$ sudo download-mibs

To have the new MIBs recognized by net-snmp, edit /etc/snmp/snmp.conf file as follows:

$ cat /etc/snmp/snmp.conf
mibs +ALL
$

SNMP MIB Browser on Ubuntu Workstation

Updated on June 2, 2013

Ubuntu Linux is arguably the most popular Linux distribution today. Well designed and easy-to-use as a desktop, it is also an excellent choice for any kind of server infrastructure in datacenters. In fact, according to W3Tech, Ubuntu server is right now in the second position and growing fast as a webserver.

In a previous article I looked at installing a basic network router using RCP100 on a Ubuntu 12.04 computer. Today, I will take a look at using Ubuntu for some more serious SNMP work.
