Hi there
Have you downloaded it from the TS2 site yet, how much help do you need?
Do you need to run it on a box with a firewall on it?
What distro are you using?
I have a TS2 server installed on a Fedora Core2 Box running Firestarter. I just installed the packages then ran the Firestarter wizard forwarded the correct ports (from the help pages on TeamSpeak site)
I know this is naughty but why repeat what has already been done elsewhere, the link...
http://www.fedoraforum.org/forum/showthread.php?t=23702 has a top article for you to follow, no matter what your lvl of expertise.
Regards
Allan
