hostname modification

[Bruno Dostie]

I have recovered an HP-UX 10.20 server using an Ignite tape. During recovery I ran in options to modify hostname ans IP address.
Nodename and IP address have been applied, but hostname is always the name of the original server. I have tried "set_parms hostname" command to modify hostname without results. "hostname returns original name value. if I uses hostname newservername, and reboot system, original servername is back again.

Any idea ?

Pls check the following config files

/etc/rc.config.d/netconf
/etc/hosts

Hi,


chech HOSTNAME variable in file
/etc/rc.config.d/netconf

HI,
# set_parms hostname
should work and it takes care of all associated files.
You only have to update /etc/hosts with the proper hostname and IP address.
If you want to change both IP and Hostname better to use:

# set_parms initial

And try setting the hostname and Ip address alongwith subnet mask and all required network configuration.
This will reboot the server and it should work fine with the new name.

After reboot check by
#hostname
command.

Hope that helps.

netconf file contents:
HOSTNAME=newservername
OPERATING_SYSTEM=newservername

etc/hosts file contents:
ddd.ddd.ddd.ddd newservername


uname -n command returns newservername
hostname command returns originalservername

Hi Bruno,

Look for any 'old' netconf files under /etc/rc.config.d/ directory.

#cd /etc/rc.config.d
#grep 'oldservername' *

See if there are any files that look like netconf file but with different names.

All the files in this directory will be sourced during the system startup. So, if there are any file that have "HOSTNAME="oldname"" line, then unexpected results can occur.

The script /sbin/init.d/hostname sets the hostname. The file also talks about nodename.

Do you have same setting for both??

Do as follows.

/etc/set_params hostname
uname -S "hostname" (this will set nodename)
Check files and make sure they reflect correct setting.

/etc/hosts (make sure that hostname entry is just bellow the loopback entry)
/etc/rc.config.d/netconf

Sridhar pointed directly on my problem....

in etc/rc.config.d directory
two files named netconf and netconf_990625

solution:
1- from there, I have created a directory named oldfiles, put netconf_990625 in this brand new directory,

2- replaced
HOSTNAME=newservername by
HOSTNAME="newservername" I don't know if it may have incidence but it works now


rebooted and everythings are OK.

thanks to all for your quick responses.

This is a common but very critical issue: NO temp or archive files allowed in /etc/rc.config.d! If you need to keep old copies, create a parallel directory lie etcrc.config.d.old and move old copies there. During bootup, *every* file in /etc/rc.config.d is executed in alphabetical order.
