Installing The Nagios Ubuntu and Debian Linux Agent
This document describes how to install the Linux monitoring agent on target Ubuntu and Debian servers (including Ubuntu variants such as Kubuntu and Edubuntu). This Ubuntu/Debian family version offers an easy way to install the agent using your distribution’s package management system. These steps will likely also work with little to no modification on other related distributions, such as CrunchBang, easypeasy, gNewSense, Xandros, MEPIS, Mint, Knoppix, Baltix, Guadalinux, eBox, Untangle, and Vyatta.
If you’re looking for the agent for CentOS, Red Hat, and Fedora, see this document instead.
