Hi Gurus,

Is it possible to change the hostname online with out reboot in HPUX ? If so what is the procedure ?

With Regards,

You can do it by # hostname
Look at # man hostname for more details.

Hi,
hostname can help u.
But next reboot will not have the new hostname.


It is better to use /sbin/set_parms to change system setting. set_parms will ask you whether you want to reboot the system; this is necessary in order to apply the configuration changes. You can answer "Yes, Reboot", or you can answer "No, Do Not Reboot" and reboot at a later time.

Hi Thanks for the info,

AS i summarise:

Changing the hostname using #hostname is dynamic but wont be in effect after next reboot.

set_params will be in effect only after next reboot.

Is there any way to change it dynamically as well to retain after newx reboot , by manually editing some files-like that ?

With Regards,

Siva.

Actually, /sbin/set_parms will change the hostname dynamically. The program suggests that you reboot, but you do not have to.

Hi,
I believe /sbin/set_parms is the only possible way to do it. This never compel You to reboot. It is upto U to reboot now or latter.

Yes.

Steps:

1) hostname
2) uname -S
3) Update HOSTNAME entry in /etc/rc.config.d/netconf file.

It will work.

hth.

When I do set_params hostname and change the hostname, it is not getting into effect immediately ( still the old hostname continues ) only after the reboot it gets into effect.

Did you follow my steps? It will make temporary and permanent setting changes too.
