AWStats is a log analyzer for apache logs. It is available at http://awstats.sourceforge.net/.

AWStats consists of a number of perl scripts and related files. There is no build in the sense of compiling required. Even though awstats has been designed as a cgi that creates statistics dynamically it also supports static html pages. I choose to run awstats on a daily basis to generate static pages. No cgi access provided. This eliminates all cgi related security risks and also places the load of processing log information at a controlled time when overall server load is low. (more…)

These instructions describe the installation of a Debian GNU/Linux based mail server. The server is a closed system, without user shell accounts. Mail accounts are administered using web based tools. This provides for excellent system security.

Note that these instructions are based on my installation notes, just prettied up a little. A fair bit of system administration knowledge is assumed. The information concentrates on installation and configuration of components that comprise the mail system. Setting passwords, adding users, configuring networking aren’t touched on and tasks the reader should be familiar with. With that out of the way, enjoy! (more…)
