Hi,

In our environment I have to configure NIS Master & Slave configuration. I have configured it successfully.
I have one query "how the NIS information will propagate from NIS master to NIS slave & vicevarsa", is there any specific command & what is the command and architecture?

Thanks & regards.

dezavu,

If you have a typical configuration, you should have the ypservers file located at /var/yp/ypservers. Enter the names of all of your NIS servers in this file. When you make changes to NIS, you run the command make -C /var/yp and it will read the servers to push the updated information to from the /var/yp/ypservers file.

HTH

Thanks!!!!!!!!!!!!!!!

Hi,
One more issue in NIS! In RHEL-4 if we configure NIS-Client such as,

In /etc/yp.conf----
domain <nis domain> server <master server hostname/ip address> server <slave server hostname/ip address>
OR,
domain <nis domain> server <slave server hostname/ip address> server <master server hostname/ip address>

the NIS fail over will (when master server will down the Client is unable to connect to the slave server or vice verse until or unless we will restart the 'yubind' service) not happen.
How do we fix it without restart the 'ypbind' service? Whether the issue is still with RHEL-5, if not then how it fixed.

dezavu,

If you have your NIS master and NIS slave servers configured properly, you need to make sure the ypxfrd service is running. I would also make sure that you set this service to start up on boot. This service is what actually propagates the changes from the master to the slaves when you update NIS. This service should be running on both the Master and the Slave NIS servers.

Here is a pretty good NIS tutorial if you want to make sure that you have all the bases covered in your configurations.

There is no abnormality in our environment of NIS configuration.
It seem I am unable to describe my issue properly. I will tell you the scenario, in RHEL4 when I configure "/etc/yp.conf" file on Client such a way like,
"domain NIS-domain-name server NIS-master-server-name NIS-slave-server-name"
but when NIS-master-server being unavailable the Client will not be able to collect the database from NIS-slave-server automatically until I have started the services.

But if I configure "/etc/yp.conf" file on Client like,
"domain NIS-domain-name broadcast"
then Client will able to collect the database form any available NIS-server (either master or any of slaves).

My question is in RHEL5 we need to follow the same configuration or else?
