I found this howto for installing Nagios on Linode and thought I'd share it after using it to successfully install and configure Nagios.

Nagios is a flexible monitoring system framework that makes it possible to maintain consistent monitoring of a broad range of infrastructural components. Many users use Nagios to monitor a broad range of network services over protocols that include SMTP and POP3 (email), HTTP (web), ICMP (ping), and SSH. In addition to simple uptime monitoring, Nagios also contains features for advanced notification and graphing as well as an extensible plugin architecture that allows users to develop simple plugins for accessing unique monitoring information and providing customized reports.

Hey everyone,

I was late in ordering our 10.04 CDs but they arrived today. If you want/need Ubuntu/Kubuntu/ and/or Server CDs please respond to this email with your Name and shipping address. It would also be nice if you could help with the cost of shipping as it will cost me to send them to you. In the PHX valley they will be available free at upcoming Installfest and PLUG east side meeting and east side Stammtische.
