Ideally (as written in distrib.its), you'd like to have a file somewhere where you set your system name, IP address and other configuration data, and let ITS read it at startup. Unfortunately, that's not the way it works…

NOTE that all $ below are ESCAPEs!! Also, where it says XY, you should substitute your new system name.

NOTE that you should read distrib.its before you do any of this, so you know what you're doing! This is just summing up the stuff, filling in some details. If you're happy with one of the standard names (AI, ML, MC, MD, MX…) and don't plan on interacting with other ITS systems, it's much easier to forget the whole thing.
