If you host for JK2 1.02, you might be interested in my new patch for the windows dedicated server, JK2Ded 1.02E.
It's fixed for Msgboom, Forcecrash, Savanna crash, and of course I've applied luigi's patches. As of now, this is the least vulnerable dedicated server available for jk2 1.02
Sorry, no Linux yet.
