OK, I have been wondering about this for a while and finally seek an answer. My laptop, as is proper, gets moved around a lot and connects to various networks. I have left the hostname on it as localhost.localdomain because this, so far, is the only name that hasn't caused problems of some sort or other.
I would like to give my laptop a better, more distinctive name than localhost but it must be a name that will actually work, regardless of the network I connect to (my university, military network, home). All networks I tie into use dhcp. Can someone please explain to me how to give my system a name that will stick and not cause problems for the various networks I might connect to? I have tried various hostnames and they either produce "invalid name" errors of some sort or they dick up my ability to connect to a given network. I need to know how to give my laptop a universal hostname that will follow it wherever I take it and regardless of the dhcp network I connect to. Doable? Or am I doomed to always be localhost.localdomain? praedor
