Are there any good or possibly better alternatives for webmin ?. Basically I want to have one single application to monitor the entire Ubuntu system / network / ... , etc.
Webmin is a web-based interface for system administration for Unix. Using any modern web-browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like
/etc/passwd
, and lets you manage a system from the console or remotely. See the standard modules page for a list of all the functions built into Webmin, or check out the screenshots.
There is something called Ebox. I've only heard good things about it. It's free software and it's in the archives. It has many modules for different things, like network. They've renamed it to Zentyal, but it's still called Ebox in the archives. You can read about it here: http://www.zentyal.org/
I use Ajenti. Support is very well, too.

There is a comparison on Wikipedia:

Since answers which only contain a link get closed soon, I added a screenshot of the current wikipedia comparison:
http://alternativeto.net/software/webmin/ lists a bunch, but watch the licensing, if it matters... many are commercial, freemium, or open source but not free-as-in-freedom.
DirectAdmin is a relatively lightweight control panel that supports Linux. It has all of the basic features of a control panel, including support for multi-customer setups.
