Hello All,

Does some one know how to synchronize the primary name server with the secondary without knowing the domains on which synchronization failed.

I have just done /usr/sbin/ndc reload

Alternatively how do i find out the domains on which synchronization failed?

How do you know they didn't sync.?

You don't sync the master with the salve but the slave with the master.
Check the config on the slave to see what it believes are the zones it receives from the master.

The serial numbers in the zones files will tell you if they updated or not. They should be the same as on the master.

Well, here is what I did; I randomly took a domain.

1. Saw that the A record on slave was not Synched with the master.
2. Forcefully Synched the A record of the domain on the Slave in accordance with the master.

What logs can I access on the Master to see all domains that are not Synched with Slave?

Additionally, when you say "check the config on the slave to see what it believes are the zones it receives from the master" could you elaborate a bit further.

I am a beginner; learning every day. I could understand what you have mentioned about the serial numbers.

Thanks for your time

How did you do this?
The proper way would have been to update the serial number on the master and see if that updates the slave.

That would all depend on what youe are logging and how you are logging it.
Without knowing the config for logging I really cannot say.


Sure. On the slave look at named.conf

In the file there should be something like this:

   zone "example.com" in {
   type slave;
   file "example.com.db";
   masters { <Master's IP>; };
