HPUX Hostname Change

Scottie Cameron — Tue, 20 Aug 2002 20:59:35 GMT

Anyone know how to change a HPUX 11.0 server???s hostname? I figured out how to change the IP, but have been told that you need to change the Hostname in several places and not just in SAM.

set_parms hostname.

The cleanest way is ..
# /sbin/set_parms hostname
It'll prompt for you to reboot the system after the change is done.

Hi:

At a minimum, you need to change the hostname in '/etc/hosts' and '/etc/rc.config.d/netconf' and reboot.

As noted, this can also be done by executing '/sbin/set_parms' with the new hostname passed as an argument.

If you are running DNS, you may need to make additonal changes to reflect the hostname change.

Regards!

You can do it through SAM. Once done, check the files - /etc/rc.config.d/netconf and /etc/hosts. Other method is /sbin/set_parms. You need to restart after changing the name. Give any name which is equal to or less that 8 characters!

Scottie,

You should use the command "set_parms hostname" (login as root) for changing hostname. The set_parms program supposed to update ALL necessary files for you. Direct update to /etc/rc.config.d/netconf and /etc/hosts will do too but still I believe using an automated process (running set_parms in your case) is the proper way.

SAM works too, but it has been un-predictable for me in the past. In one version it works but it might not in the next version.

Rgds,
Philip

An add to Harry's soapbox.
Be sure to check /var/adm/inetd.sec just in case there are any entries that need to be updated.

It's nice to know there are others out there that are annoyed with set_parms
Although, it's okay on very, very generic network setups.

Harry,

Thank You! I had thought it was my inexperience that led to my problems with set_parms. I had so many problems with it years ago that I stopped using it and haven't gone back.

Of course, my propensity to want to manually edit configuration files may have had something to do with it also!

Kelli & Tom,

It works fine when it's used to set up a server for the first time, but after that it is as useful as the output from /dev/null.

Set_parms hostname and editing the /etc/hosts & /etc/rc.config.d/netconf has seemed to work in changing the hostname; I do not have a /var/adm/inetd.sec file to check, per Kelli's directions.

Everything looks to have worked; yet the network is not ???talking???. We get a link light on the nic, but when my network analyst tries to get the MAC Address from the NIC, it will not show. My guess is that the NIC has/had been disabled when the server was shutdown (it had problems last year and was sent to the funny farm for awhile??? Kinda like management after budget analyses???).

Thank you all for your help, I guess it???s back to the bar, err, a, the computer room to figure this out???

hello,

if you think the NIC is disabled, then you can enable it through SAM. If the NIC status is down, then make it up with ifconfig command:
# lanscan
# ifconfig lan? up

Did you remember to issue the command hostname to change the name after editing /etc/rc.config.d/netconf and /etc/hosts.

hostname new_hostname

verify the new name with hostname with no arguements. That way you don't have to reboot the computer to change the name.

ifconfig lan0

should tell you if the NIC is active or not, or course you would substitute you lan instance in the above command i.e. lan0 lan1 etc.

Well, thank you Sajid & John for the scanlan & ifconfig command; I didn't know that one (or many others, I am new at playing with UNIX).

However, the error was in the physical connection to the network, not anything on the server.

======================================

Do not write netconf backup file in /etc/rc.config.d.

=======================================

for example

ls -l /etc/rc .config.d/netconf*

-rw-r--r--   1 bin        bin           8559 Jun 16 10:35 netconf
-r--r--r--   1 bin        bin          15737 Feb 28 2011 netconf-ipv6
-rw-r--r--   1 root       sys           8517 Aug 17 2012 netconf_badname-backup    <- remove or move this file

see

cat /sbin/rc1.d/S320hostname
