[hobbit] DNS not ok using xymon but ok using BB

[Greg Hubbard]

The ares support has to do with how the Xymon server resolves host names.
The DNS test is something entirely different -- the bbnet host tries to
interact with the DNS server on the DNS port on the remote host.

You might use snoop or tcpdump to capture the activity between the bbnet
host and the failing DNS server to see what is being sent and what is being
returned.  Then you can compare this with one of the servers that appears
okay.  There may be something in the DNS server configuration itself that is
causing the problem, like maybe the DNS servers have IP address restrictions
in them or something like that.
