Slave DNS Replication
1 Attachment(s)
hi guys
I configured a master DNS server 192.168.2.10 working OK. after that I configure a DNS Slave Server (92.168.2.11)the initial replication worked fine. . this is test environment for my certification. I see how the zones from my master are transferred zones in Master training.com.db transferred zone to my slave when I started named service sec.training.com.db that's OK but I added some IPs to resolve to my master zone webserver IN A 192.168.2.30 fileserver IN A 192.168.2.31 I restart/reload named on master and after that I go to slave and restart/reload but zones wuth the new values are not replicated.... any idea how long does it take for slave to take the changes from master? how is the procedure manual or automatic? I see If I go to slave and delete sec.training.com and restart named the zone with the changes is transferred but that is very manual... I am including my DNS Configuration so you can take a look thanks a lot |
Did you adjust the zone serial number on the master?
