These days I find myself having a preference for a text editor over a gui 
helper. You don't really know what a gui helper application is doing in the 
background unless you have the time, inclination and knowledge to dig out the 
source and find out.

With a text editor you know exactly what you personally have done and where 
i.e. if you set up a firewall script that gets called from /etc/rc.local and 
find that you've screwed up i.e. locked yourself out of ssh for instance, you 
know exactly where to go to kill it or edit it from a console to make it work 
again.

I used to have my home server set up using webmin but found later that I 
simply could not understand how it worked so now I just use joe and keep 
notes about what I did and why. Always keep notes and a backup of /etc/.
