[syslog-ng]logging to a central server

Hey all, Excuse the ignorance, first of all. I have always just used syslog/syslog-ng as logging sources on local machines, I've yet to use the network functionality. How exactly would one configure a host, so that it sends all logs to a central syslog-ng machine? I am using linux, I assume that I would just change the unix-stream to an IP address, or something of the source? Thanks in advance everyone.
