NIS

[Bona_1]

Is there ANYWAY to reverse NIS? Some dude seems to configured NIS on my server, and I'm wondering whether it's possible to deconfigure it.

Hi,

What do you mean with "configuring NIS", NIS server or NIS client ?

Of course it is possible to deconfigure, use SAM or edit the file /etc/rc.config.d/namesvrs

You can simply change your /etc/nsswitch.conf file to ignore nis:hosts:

files[NOTFOUND=continue UNAVAIL=continue] dns [NOTFOUND=continue UNAVAIL=continue TRY
AGAIN=return] nis

The above would search NIS last - you can just leave off the nis entry, too.

Yes, of course. I am a little surprised that you let "some dude" do anything on "your" server but the answer is to cd to /sbin/init.d and
./ nis.client stop
./ nis.server stop

Edit /etc/rc.config.d/namesvrs and set the NIS_SERVER and/or NIS_CLIENT values to zero. You also need to edit /etc/nsswitch.conf to not use NIS. Things get more complicated depending upon what NIS was doing for you. You may need a new passwd and/or group file. You may need a new /etc/services file and if NIS was doing hostname resolution then you will need DNS and/or /etc/hosts entries.

After doing all this, the easist answer is to then reboot.

NOTE: If this box was the master NIS server then you actions could affect many, many boxes so look before you leap.

Yes,

First change /etc/nsswitch.conf so everything stops using nis.

Then get a copy of the maps (ypcat), manually copy them to the relevant files (passwd, hosts etc) making sure you have a copy of them first. Remove the NIS "+" entries if they are there. Stop NIS daemons.

Perhaps i should make myself more precise. I can no longer administer users... that is my immediate concern. The server is simply a test server, not live at all. I can't adjust the user password, when i type the passwd command, it gives me the error

# passwd
Supported configurations for passwd management are as follows:
passwd: files
passwd: files ldap
passwd: files nis
passwd: files nisplus
passwd: compat
passwd: compat AND
passwd_compat: nisplus


thanks

I think that might help.
