How to change the host name?

Hi,
I have a Red Hat 9 Linux box, and I want to change the host name of this machine. Can someone tell me how can this be done?

Thanks,
Aroop

several ways

you can edit /etc/sysconfig/network and change HOSTNAME=

echo newhostname >/proc/sys/kernel/hostname

hostname newhostname

by far the easiest is to make a file called /etc/hostname containing your hostname for example "mymachine"

then make a file /etc/domainname containing your dns domain name for example "isp.com".
the changes should take effect immediately

Hi,

there's also a command named "hostname"

Oliv, the command hostname only changes the host name temporarily, it wont save it on next reboot. I was looking for a permanent solution!!
Thanks anyway.

repeating myself ....

when you modify HOSTNAME value in /etc/sysconfig/network, this change is permanent.

when you write it to the proc file, the change is immediate but not permanent.

Hi ppuru,
I had applied your solution and got permanent results! Thanks.

Yes that's true... except if you put this command in a boot script

How I can change the hostname in a Debian system?

This modification affect to the system configuration (local mail, etc.) or the changes are automatically detected?

Thanks a lot
