Some of these files are hardlinked to the "real" files under /etc/, /etc/sysconfig/ and /etc/sysconfig/network-scripts/ and others are copied when you CHOSE to SAVE from within system-config-network..... The reason behind this is to support multiple "profiles" with completely different settings. The hardlinked files would be OK when editing them outside of system-config-network. The problem you experienced is one that is not hardlinked, though I am not sure "how" you changed your name before, see below.... Now, back to your original problem. The machine's "name" is initially set to the HOSTNAME= variable found in /etc/sysconfig/network, which happens to be one of the files that system-config-network will fix when needed.... The /etc/hosts file is simply used by the name service client resolver on the machine to translate "locally" names into numbers and vice versa - it has nothing to do with "setting" your hostname. Nor does it have anything to do with how "others" perceive your hostname. Others will translate some hostname into your number based on the DNS servers that "they" are configured to point to..... Now the flip side that you did not ask.... Are you doing Dynamic DNS? If you are this should have been part of "providing good information" for the people that are trying to help you.... If not, hopefully the above is pointing you in the correct direction.... --Rob
