redhats named
By Jesse Morgan | December 19, 2005
a question I had in IRC today… anyone want to take a shot?
08:21 < morgajelWork> ok, explain this to me.
08:21 < morgajelWork> I wrote an iptables script that was pretty strict.
08:22 < morgajelWork> it only allows tcp and udp on 53 for dns, and tcp for ssh. and related,established for all
08:22 < morgajelWork> the defauly policy is to drop
08:22 < morgajelWork> when I try to halt this redhat box, it locked up while trying to shut down Named
08:23 < morgajelWork> so I on a fluke change the default policy to ACCEPT
08:23 < morgajelWork> BAM it works
08:23 < morgajelWork> so riddle me this…
08:23 < morgajelWork> WTF is redhat’s /etc/init.d/named doing to lock up like that?
and yes, this is RHEL v3 with the latest updates.

after reviewing their script, it uses something called rndc, which is used by the startup script to connect to the service to shut it down.
Gentoo uses the same thing.
I’m sorta boggled as to why it’s behaving like this, and what ports it uses, but I guess now I know where to look.
