DNS notifies

Post by kesor »

These two lines in my logs are something that I would like to not see.
Apr 1 22:50:52 <3.6> amder named[13054]: client 67.118.43.92#32768: view external: received notify for zone 'kesor.net'
Apr 1 22:50:52 <3.6> amder named[13054]: zone kesor.net/IN/external: refused notify from non-master: 67.118.43.92#32768
There just might be a reason why a slave DNS server would want to send a notify, but I fail to see it. Maybe for people that cant send dns transfers from their own servers could benefit from this. But when rollernet is used purely as a backup, the one server sending notifies should be the master server.

A single line in zone declartion in named.conf (bind9) saying "notify no;" should suffice to disable the rollernet server from sending notifies.

Do correct me if I'm wrong.

Thanks for the great service.

Since we only offer a secondary service at this time, and don't allow AXFR from our servers, you are correct. This has been changed to a global disable. It may reappear as a config option in the future, but the default will remain "no". I apologize for the oversight.
