I have a DNS Master (192.168.102.159) and Slave (192.168.102.132) servers, both are VMs, the Master configuration is fine and does both forward and reverse lookups, however, when I try zone transfers with slave, the slave throws the following error failed to connect: host unreachable, I have checked the IP addresses are correct in both conf and zone files, the zone files also show no errors in named-checkzone. This is my second setup, in the earlier setup I received an error rndc.key not found followed by this error, however, in this setup I only received this error.
I have added chgrp and chown on slaves folder in Slave, however, no firewall entries are added, unsure if I have to.
