How to Change Host Name

[Patricia Tang]

Hi,

Can Anyone tell me how to change the host name.

Is it typing " hostname host-name"
and edit /etc/hosts?

Please advise
Thanks in advance.

Regards,
Pat

The only supported way to change the hostname of a system is by using

# set_parms hostname

This command will guide you through the steps to change the hostname.

/sbin/set_parms hostname

Hi,

First make changes you need in your DNS server. After that:
set_parms
You will see all "set_parms possibilities"
The right is:
set_parms hostname

You can cahnge the name in an unsupported fashon

1) edit /etc/hosts
[...]
2) edit /etc/rc.config.d/netconf
HOSTNAME=
3) change hostname
# /sbin/init.d/hostname start

No reboot!!!

However, you will need to update DNS/NIS/all you hosts files to replicate this change 'round your system. I would suggest leaving the old hostname as an alias for a while!

I do agree with the above, HP may not support this method (without a re-boot). Some of your applications may require a hostname, which has just changed. You'll need to suck it & see

hi,
just want to add a little point: after the "set_parms" you should check your /etc/hosts file because all you aliases for this server will be gone.

If you change the host name in the "unsupported" method, you run the risk of having problems with software installs in the future. Both the /var/adm/sw/products/ifiles and /var/adm/sw/security directories contain files that have the hostname of the system burned in (_ACL and _OWNER). The safest method is what Carsten reccommended.

# set_parms hostname
