Change Nameservices after install. 1

[deetee2k]

Here's a doozy,
We have accidentally installed NIS onto a solaris 8 machine during install time. The machine no longer boots (NIS timeouts).

My question is, is it possible to change the name service from NIS to DHCP (or None as in the install) from the boot prompt or do I have to rebuild the machine?

Ta,

DHCP is not a name service. NIS is.

To remove NIS you can follow the followin commands:
1. boot -s
2. cd /etc
3. rm defaultdomain
4. cp nsswitch.files nsswitch.conf
5. reboot

This takes off the NIS.

Another way to change the settings on a machine is with:
1. boot -s
2. sys-unconfig
3. answer y
4. and then boot
This will erase all your settings Hostname, IP nameservice and root password, time. After which you will be able to reneter it.

Thanks, but no success.

Your first suggestion will not work since the boot process will halt with a "WARNING: Timed out waiting for NIS to come up" and will refuse to go any further.

Your second suggestion will not work since the command interpreter doesn't understand the 'sys-unconfig' command and returns me to the '?' prompt.

Any other ideas?
Thanks a million,

Did yoou try either solution. The s in the boot -s brings the computer to single user. It does this before it run the script that looks for the NIS server.

Regarding the second suggestion. After you have booted as single user it recognizes the command.

I have done it a lot of times, it works.

Have you tried running sys-unconfig from:

/usr/sbin/sys-unconfig

? Good luck.

A little mistake, I should have gone into maintenance mode! This must be my 'feeling thick' day.
