Secondary DNS cannot transfer zone

Submit to reddit

I’m no Bind expert but I’m not a beginner either. I was configuring a secondary backup DNS for a master server and I noticed that after configuring everything the zones didn’t get replicated on the slave DNS. I checked the logs and saw the following:

First I thought there was a mistake related to a missing permission on the master configuration

allow-transfer { aaa.bbb.ccc.ddd; };

I double checked but the permissions were set correctly. The solution was easier (after finding it) than expected. The folder where the zones would have landed was not writable by the Bind user (named in my case)
