Slave DNS


I have my virtualmin installation as a master DNS, and I installed another instance but as a slave DNS this time. It worked, I can see the zones, slave type, but when I change my zone DNS on the master it takes a long time to update the slave, is it normal or it needs to be configured somewhere?



When you click “Apply changes” after editing the master, it should trigger a zone transfer; so, it shouldn’t take more than a couple of seconds, but it does require you to click that “Apply” link in the upper right hand corner.

Are you doing that, and still seeing a delay? Does anything appear in the logs when you click it?
