how to st up privete cabal server?

what I need to set up server with hamaci is better?
or not...

Without Hamachi is better but it depends on your network setup, some configurations and some routers can't host pulic servers. The only way to know is to test.

ok I downloaded centos with instaled cabal sever now how I run it to others can play and register?

lol....look on the tutorial section be4 asking....it posted even videos on 3 steps to set a server

enough of this, don`t be lazy search.
