How do you change your hostname?
 

I went to my commandline to change my host name with su with cmd: hostname newlocalhostname

This changed it but when I reboot I get my same old localhost hostname... can you tell me what I'm doing wrong?

try this (as root)

echo "new_host_name" > /etc/hostname

Which distro and version are you using? Be sure to check the online docs for that distrobution and it should tell you how to set your hostname, as that is very basic stuff on a linux box (Shouldn't it be manditory??)

I'm using Turbo Linux 10F

All good suggestions above :)

As root

cheers

This change will not stay after a reboot, which is his original problem. On many distros you have to change it in the file /etc/sysconfig/network, so if you have a directory /etc/sysconfig/ already there then thats likely how you have to do it. Add a line to the file 'HOSTNAME=myhostname' (without the quotes).

What does your /etc/hostname file say?
