A new version released today. Webmin is a great tool for administering a Linux, OS X or Windows (with Cygwin) machine remotely via a web browser. Based in Perl, it includes modules for many of the popular tools on the platforms: Apache, IPTables, Samba, MySQL, PostGreSQL. It’s a very handy way to familiarize yourself with the administrative options available with those tools, and often offers a simpler and easy to use interface than the tool itself does.
