I just installed the latest version of webmin on my CentOs 5 server. I have not used webmin in about 2 years, I can not believe how much the interface has improved. Webmin is a GUI control panel that lets you administer a Linux box.
Here is all you need to do to get it installed:
This will install some dependencies.
yum -y install perl-Net-SSLeay
Install the system:
rpm -i webmin-1.380-1.noarch.rpm
