As this box will be used for hosting websites i install Virtualmin GPL. It is a Webmin module for managing multiple virtual hosts through a single interface, Similar to Plesk or Cpanel. It supports the creation and management of Apache virtual hosts, BIND DNS domains, MySQL databases, and mailboxes and aliases with Sendmail or Postfix. It makes use of the existing Webmin modules for these servers, and so should work with any existing system configuration, rather than needing it's own mail server, web server and so on.
