hostname

Hi,
i know it's a stupid thing, but i'm not able to change the hostname on my Redhat 7.2. It's localhost now. I tried with hostname command, it changes it but after reboot restore's the old one. I had also modified the /etc/hosts and also /etc/hostname. It seems so difficult to change the hostname.

I found this entry on a different mailing list:

I recently did this, and also had to change:
/proc/sys/kernel/hostname, via sysctl. I also restarted daemons, just
in case (postfix, apache, etc). But still had the problem with X as
the OP.

I appreciate your help Daimian but unfortunately it doesn't work! I also rebooted the ws, but without result.
On other unix systems (hpux,solaris..) it's so simple to change a hostname. On redhat there's something strange. The /etc/HOSTNAME does not exist, i don't know where redhat stores the hostname. I've seen the hostname man and it says to change that file, but it seems that at boot it isn't read!

Tarek, just go to /etc/sysconfig and vi network, there should be an entry for HOSTNAME=blabla, change that to whatever you want. You don't have to reboot, type "hostname " or just reboot. This should work.

The hostname is set in /etc/sysconfig/network by anaconda. You can manually change it there, if you like.

hi,

You must modify the following config file :

/etc/sysconfig/network

NETWORKING=yes
HOSTNAME=yourhostname

then do a restart of your network

service network restart or do a reboot
