Changing the Host Name?

as400 · 04-15-2007, 05:39 AM

I am running Solaris 10 on x86 and I want to change the Host Nmae from SERVER2 to something else.
How can I do this?

Open up /etc/hostname with your favourite text editor

Actually /etc/nodename, and possibly /etc/hostname.<interface> if you have a static IP address.

Check to make sure SMC still works after doing that. I had issues with SMC failing on a box where I changed the hostname that way. Not sure if it was the hostname change or something else going on, but SMC couldn't find the toolbox anymore.

you should be looking too at /etc/hosts and /etc/inet/ipnodes.

Your hostname is located in several locations.

Others also mentioned:

/etc/nodename
/etc/hostname.card_type_here

Certain files are now deprecated in solaris 10:

/etc/net/ticots/hosts
/etc/net/ticlts/hosts
/etc/net/ticotsord/hosts

Some directories also contain your hostname:

/var/crash (for crash dumps)
/var/spool/lp/requests (for printing)

Cheers.

Forgot to mention regarding smc.

smc may fail to load properly if it was loaded prior to the name change because
it contains xml files in /var which will still have your old hostname in them.
Those files end with "*.tbx" for toolboxes.

Although I have not tried this on x86, you can use sys-unconfig in sparc systems very easily. It halts your system. At boot time, it will ask you to
add the new hostname, ip, password and a few other things such as naming service info and so forth.

Good luck

Yes, sys-unconfig works equally fine on x86 architecture too and is indeed a simple way to rename a Solaris machine without requiring any specific knowledge of its internal files.

I suggest people to have a look at its manual page before running it though, as the command go beyond just renaming the machine.
