[rhn-users] hostname in 'localhost' line of /etc/hosts

[Sullivan, Michael]

Hello All;
 
My 2cnt's.......looking at the /etc/init.d script "network", it sources the file /etc/sysconfig/network-scripts/network-functions.......looking at the sourced file the hostname is validated and set......if the test condition fails "localhost.localdomain" is written off.......looking for the dhcp functions, /etc/sysconfig/dhcp* has several "boot-up" parameters available....are any of those set?.........and if Shadd's issue is with Kudzu, perhaps a driver issue is under-lining and the system keeps finding the network-devices, activating it, turning on dhcp by default and setting the entry's.......Are you're boxes being rebooted regularly forcing this possible condition?......I'm also assuming you've scoured over the /var/log directory looking for any indication of changes........looking for the most recent changed files or hardware status. 
 
--Mike.

	I have seen the same thing. Also for some reason if you don't disable Kudzu the problem can resurface after reboot. I would recommend the BugZilla

	Thanks for your reply,
	
	but that is not the problem:
	I know what must be written into the related files, to get the network
	working.
	What I want to understand is, why the redhad configuration tools do create
	configuration files, which prevent the correct behavior of application
	programs.
	Whenever something like this happens, we get a suppert event, and need a
	debug session with 'vi' to correct the files, because the suspicious
	line is never
	displayed in in the graphical tools.
	
	My intention to ask in this list was, if anybody can tell why, or
	should I open a
	bug report on bugzilla?
	
	Best Regards
	 Günter
