Installing and Configuring Exim4

Post date: February 25, 2006, 12:02 Category: Network Views: 3756 Comments
Tutorial quote: Installion of Exim4 from the latest Debian GNU/Linux packages is easy. The installation is now based around debconf. If you are upgrading from a simple Exim3 configuration, you can use exim_convert4r4 to convert your configuration file to the new format. If you used the previous version of this guide, which covered Exim3, the conversion should succeed without incident. I intend to discuss configuration via debconf, including setting up local delivery to Maildir format, handling local domain email, and configuring smarthosting for outbound email.

Server Monitoring With munin And monit On Mandriva 2008.0

Post date: February 26, 2008, 11:02 Category: Installing Views: 3832 Comments
Tutorial quote: In this article I will describe how you can monitor your Mandriva 2008.0 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphic that lets you recognize current or upcoming problems, and a watchdog that ensures the availability of the monitored services.
