Interesting, so it's not just me then. I'm having trouble getting
anything on my DNS servers to resolve. I'm using the DNS configuration
tool to set up a master zone for a local domain (mydomain.local), yet
nothing is working. I've checked ports, firewall, and selinux settings.
Still no dice.
Ideas welcome - I'm not sure what I'm missing / doing wrong.
Cheers,
Chris
