Hi, ( running solaris 8 )
I know how to change the hostname temparily, by login in as root
typing
hostname = xxxxx

but, this obviously goes when the system is rebooted. I'm not sure what files need changing to make this a permant change.
Could anyone help me please?

Check the /etc/hosts table, i think you need to change the hostname here also.

After you did this, you can check the /etc directory for more hits on your old hostname:
cd /etc
grep <old hostname> *

if you find some, you had to change then too

You need to change /etc/hostname.interface (.ge, .hme0,.le0) and /etc/nodename. Then reboot the machine. You can make the necessary changes in your /etc/hosts file to the new hostname.

You can use the command : /usr/sbin/sys-unconfig

The command will be change all necessary files.

For more information, see man pages.

I hope help you !

Files to change ..
hosts
hostname.<nterface>

I forgot to mention, that I'm using DHCP, and my sun gets assigned the name "unknown"

I tried some of the advice, but I'm still struggling. when it boots up it still comes up with the name unknown.

any more ideas.

You might need to change something on the DHCP server, or even possibly on a DNS server (I'm not sure if Solaris gets it's hostname from reverse-DNS after getting an address via DHCP).
You should check with your network administrator.
