Change hostname

madmat · #1 09-14-2007

Hello,

I would like to change the hostname on a Linux server (RHEL4).
I try different methods in vain :
- by using hostname command
- by changing /etc/hosts and /etc/hostname

But after restarting server, the old hostname re-appears...

And the file ./proc/sys/kernel/hostname contains again the old value (however modified after hostname command)

Any idea ?

Correction : OS version is RHEL 2.1

check under /etc/sysconfig

[root@myBOX etc]# cd /etc/sysconfig/

[root@myBOX sysconfig]# grep myBOX *
network:HOSTNAME=myBOX.domain.com

Here is a quote from the net :

Quote:

RedHat based system use the file /etc/sysconfig/network to read the saved hostname at system boot. This is set using the init script /etc/rc.d/rc.sysinit
/etc/sysconfig/network
NETWORKING=yes
HOSTNAME=”plain.domainname.com”
GATEWAY=”192.168.0.1″
GATEWAYDEV=”eth0″
FORWARD_IPV4=”yes”

So in order to preserve your change on system reboot edit this file and enter the appropriate name using the HOSTNAME variable.
