Again, that doesn't "set the hostname". The hostname is set elsewhere. All the hosts file is doing is associating a name with an numerical IP address, and optional aliases (the one word abbreviated names listed after the fully qualified ones with dots in them - you can have several aliases, if you want).
e.g. 192.168.1.2 zeenet.locallan.org zeenet zeeweb webserver
Thanks for the such a long explanation and sorry for some misunderstanding. What I was reffering as hostname was actually an aliases (may be windows hang over). Ohter windows machines recognized this one by the alias. I understand that the hostname is set in the /etc/sysconfig/network file which in my case is ========= NETWORKING=yes HOSTNAME=zeent.locallan.org ======== My question is not about this at all nor on how to do the networking but rather the issue related with 1. wiping out the "127.0.0.1 localhost.localdomain localhost" line and 2. restoring my old hostname and alias from middle of nowhere which all happened using graphical configuration. So to the question is: 1. Is this the bug of grahical tool (system-config-netowork)? and 2. does same thing happens to somebofy using FC5 (try it and see if it happens)??? and lastly 3. Is this the bug of graphical tool??? Thanks!
