How are you using them? I've recently gotten back into using Ubunu 6.06LTS and am trying to grasp it as a server OS. I have a Dell PowerEdge server back at the apartment and want to use it as a backup/media server and also as a networking monitor.
For those who are using a linux-box as a network monitor, what tools are you using and do you have any links to n00b tutorials and some of the sort?
Also, kind of a random question, who is using Phlak? Any fun experiences with it?
