Unable to make action: Unable to manage service by dnsmng: dnsmng: Service named fail

[dw604]

When restarting a recently updated bind (bind 9)

I was getting errors like this in /var/log/messages:

Nov 26 04:07:31 serv named[30009]: could not open entropy source /dev/random: permission denied
Nov 26 04:07:31 serv named[30009]: using pre-chroot entropy source /dev/random
Nov 26 04:07:31 serv named[30009]: couldn't open pid file '/var/run/named/named.pid': Permission denied
Nov 26 04:07:31 serv named[30009]: exiting (due to early fatal error)

...and like this in Plesk CP when adding IP addresses to the server:

Unable to make action: Unable to manage service by dnsmng: dnsmng: Service named failed to start

I actually had to move some stuff back into the right spot in /var/named/run-root... and update the "directory" in named.conf to "/var"
After checking to make sure rndc.conf and rndc.key had the same key and all was ok it still didn't work.

The solution was this:

Q: I'm running BIND on Red Hat Enterprise Linux or Fedora Core

The command to run is

setsebool -P named_disable_trans 1

So glad to finally fix this! Hope it helps someone...
