Can anyone tell help me figure out why this SOA is not changing no matter what I do. The zone was edited and has a new SOA but no matter what I do bind doesn't reload the zone with the new SOA. I tried rndc freeze/unfreeze and still nothing. Short of reloading bind what else can I do. TIA, Paul

Haven't done it on RHEL/CentOS 6.x yet but in RHEL5 with the bind-chroot installed I've always had: /var/named/chroot as the jail for BIND. /var/named/chroot/etc = Location of global config files such as named.conf /var/named/chroot/var/named = Location of the zone files. I don't see a /var/named

Chris this is not a dynamic zone, I do have NS RR. I had to completely restart bind for it to work. No matter what I did with the serial it wouldn't change. Never had to do this before so it's a bit odd. Named-checkzone gave me no errors and rndc reload worked fine but the zone wouldn't update.
