There is nothing more daunting than being given an Ubuntu Server to manage if you have never ever delved into the world of command line (or should that be terminal line) Linux. Thankfully though, someone saw it fit to lend a helping hand to these hapless system administrators, resulting in the very useful Webmin package.
Basically Webmin is nothing more than a web-based interface for system administration in Unix. Using any browser that supports tables and forms (and Java for the File Manager module), you can setup user accounts, Apache, DNS, file sharing, you can restart and shutdown, and so on and so forth.
Webmin consists of a simple web server, and a number of Perl CGI programs which directly update system files like /etc/inetd.conf and /etc/passwd.
Once installed on a machine (which may sometimes prove a bit tricky mind you), all a system administrator needs to do is hit that Server on port 10000 in a web browser and he’ll be good to go, now able to effortlessly control all sorts of behaviour using the nice and reasonably friendly web interface.
