You can start with checking your /etc/rc.config.d/netconf file and looking for the "Hostname" record. Make sure that wasn't changed or removed.

How are you determining it is unknown? Can you ping it from the network? Can you ping it from itself, IP or hostname?

Did you change anything recently? Are you trying to use a hostname that is longer than 8 characters?

What is mentioned in the /etc/rc.log under /sbin/rc1.d/S320hostname start output?

What run-level is your system currently in, sounds to me like it is in single-user mode ...

# who -r

Hi,

Is your server on the network?. hostname is set from /etc/rc.config.d/netconf file. Look at this file and see if "HOSTNAME" has been correctly defined. It should be less than or equal to 8 chars.

Try running

#/sbin/init.d/hostname start

See if it works or post the errors it may give.

Thank for your reply.

Hi

I'm merely reiterating what the others have said in this post but if you can confirm the following then someone may be able to help further:

1) Is your hostname defined in /etc/rc.config.d./netconf file?
2) Is your hostname set in the /etc/hosts file.
3) Examine your /etc/rc.log file and look for the output under "Output from /sbin/rc1.d/S320hostname start"
4) What does "# hostname" command return?

Cheers
Con
