Webmin is great!
I don't know why it took me so long to find it.
Since the days of Mandrake 6.0 I was a linuxconf user. It was OK, and over time it has become less and less reliable. As the distros have changed and upgraded versions of the included servers, linuxconf hasn't been something that I could rely on as much.
I was looking for information about a GUI config for apache and was introduced to webmin. It is fan-fucking-tastic. What I really like is that it gives you the ability to get the rough layout of your changes done via web forms, but then allows you to fine tune your changes by editing the text files, all in your browser window.
It supports all kinds of OSes. From *BSD, to GNU/Linux through HP/UX,Irix and Solaris you're set with webmin.
Webmin is great.
