Hi:

If you are changing *your* server's hostname or IP address, then you should run '/sbin/set_parms' to affect this. A reboot will ocurr but the change will be clean.

If you are merely adding another server's information then there is nothing you need to do after adding or changing the information.

If you are changing *your* DNS server's IPaddress, then modify '/etc/resolv.conf'. The change will be available without reboot.

Regards!

Hi (again):

If you want to change a server's hostname or its IP address, an easy way to do this is to run '/sbin/set_parms'. If you execute this without any parameters you will see the options that you have.

The 'set_parms' script is a question-and-answer program. It is a "clean" way to change a hostname, ipaddress, etc. because all the necessary configuration files are updated for you.

Changing a hostname requires a reboot afterwards. 'set_parms" accomplishes this. Changing a host's own ipaddress requires at least that the networking daemons be stopped and restarted. It is easiest to use 'set_parms" and let it reboot too.

Hi Rodh,
You don't need to do anything after adding the entries in "/etc/hosts" . Changes will immediately effective.
What James is trying to explain you is the method for changing the hostname of the server.

Adding entries in /etc/hosts will not need any reboot. If you want to change your machin'e hostname, ip-address and domain using set_parms will require reboot for making that configuration.

To check /etc/hosts working efficiency then,

# ping
