It is probably coming from the initial installation of RH Linux 8.0. I see at the command prompt that in Linux my computer is called localhost. I'd like to change this name to something else, but don't know how. Anyone can help with this? Or point me to a place where I can read.
in /etc/sysconfig/network the HOSTNAME is localhost.localdomain.
What is localdomain, I mean what does it stand for? Can I change it and what will happen if I do?
yes,
if you want a permanent change in hostid you have to reprogram the novram.
you can temporary change the hostid by execute a program . search the web for that program
