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

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.
