When having problems with named (BIND9) and DNS in general, you can do the following.

First edit /etc/named.conf and insert the following lines:

logging {
category "default" { "debug"; };
channel "debug" {
file "/var/tmp/nameddbg" versions 2 size 50m;
print-time yes;
print-category yes;
};
};

This enables logging to the file /var/named/chroot/var/tmp/nameddbg

Then you can check out the file with a tail -f.

If needed you can use rndc to check out the server status:

/usr/sbin/rndc status

Will give you an output similar to:

number of zones: 338
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
server is up and running

Where:

• number of zones is the number of domains the server replies for
• debug level is the current debug level (you can increase it with /usr/sbin/rndc trace
• xfers running are zone's trasnfers currently running
• xfers deferred are zone's transfers delayed
• soa queries in progress are the number of start of authority queries currently in progress
• query logging is the state of the query logging flag (change it via /usr/sbin/rndc querylog )

There is a good site where you can perform dns query.
