How to rename a system's hostname

[dictum9]

I have done it before, but the command (which is shown during the install process) escapes me at the moment.

You can do it manually but the easist approach is "set_parms hostname".

Hi:

# /sbin/set_parms hostname

...triggers the menu-driven change. A reboot will be required.

# hostname newname

That will change it for you. Remember to change it in the /etc/hosts and anywhere else it may be hardcoded.

Sorry, forgot to mention that my suggestion will only change it until the next reboot....you will have to do what the gentlemen above suggested to change it permanently.

Just use:

set_params hostname

Duh! *Slaps self on forehead* of course set_parms is what I was looking for.

Etc,
Also dont forget to verify that /etc/rc.config.d/netconf has been updated with HOSTNAME="new_hostname" .

Cheers,
Raj.

Hi Etc,

You just need to use "set_parms hostname" you can use "uname -S nodenmae" but this is just tempoary.

One other precaution: if you are using DNS, the nameserver will have to be updated at the time you change the hostname.
