Whether two NIS master server can exists in same domain?.

[Jaime Bolanos Rojas.]

Cenoce, according to NIS configuration, one have to be the master and the other the slave.

Presentely I have One master one slave and two node as client. I want to make one of the clinet as master and want to remove the old master.

For this i was planning to make one client as new master ( this condition there wil be two master in same domain is this posibel).

Cenoce,

Actually you have one master, that is going to be gone, that's ok becuase you have a slave that is going to take over.

You have two clients, one of them you are going to configure as a Master, that's ok, becuase when the master comes up, the Slave ( actual master ) is going to be back as the Slave.

So the correcto configuration is 1 master, 1 slave and one client, thinking also the master is also a client.

For more info take a look a this page

Just in case you need any further help:

The following instructions assume you have the old server and the new available at the same time. They also assume your NIS directory is called /var/yp/source (as mine is).

1. Transfer the contents of /var/yp/source on the old server to the same directory on the new.

2. Copy /var/yp/Makefile and /usr/sbin/ypinit from the old to the new.

3. vi /etc/rc.config.d/namesvrs on the new master. Set NIS_MASTER_SERVER=1. Set YPPASSWD_OPTIONS="/var/yp/source/passwd -m passwd PWFILE=/var/yp/source/passwd".

4. Edit the same file on the old server set NIS_MASTER_SERVER=0 and YPPASSWD_OPTIONS="/var/yp/source/fakefile -m passwd PWFILE=/var/yp/source/fakefile".

5. Run ypinit -m on the new server.

6. Run /sbin/init.d/nis.server start on the new server.

7. Run /sbin/init.d/nis.server stop on the old server.

8. Log into a random selection of clients and type ypwhich. They should be bound to the new master. As an additional check, try ypwhich -m which should show all the maps as belonging to the new server.
