Today me and Henry talked to Jeff about Wireshark. The problem at the moment is you can't capture packets that aren't traveling to your computer. If we had a hub it would work since the hub broadcasts everything on every port (yay something from Net+). What we were thinking is using wireshark on the LTSP server but rather we're going to try using tcpdump.
So for this week we're going to work on tcpdump and the rest is to be determined. We have to wait on the Jabber server patches according to Jeff.
About LPIC, I still have plenty of studying to do with not so much time.
