Thanks for the info. I am able to successfully dig the "failing" DNS server ...

I have recently installed xymon 4.2.3 on a solaris 10 platform. I also have BB running on another solaris 10 server. The BB server has been running for years.
My issue: I am monitoring seven DNS servers. BB reports all seven as DNS OK. However xymon reports five servers as 'not ok'. I am unable to determine why the DNS test fails on these servers.
I have tested by changing hobbitlaunch.cfg to use:
CMD bbtest-net --no-ares --debug --report --ping --checkresponseI did not see any useful information from the log:
2009-08-04 15:33:30 Adding to combo msg: status <server>.dns red <!-- [flags:ordastLe] --> Tue Aug 4 15:33:07 2009 dns NOT ok status <server>.dns red <!-- [flags:ordastLe] --> Tue Aug 4 15:33:07 2009 dns NOT ok
By default, the DNS test tries to resolve the host's own hostname, e.g. if this server is server.mydomain.com, you should test with:
$ dig @server.mydomain.com server.mydomain.com
You can have it test any other DNS record for any domain, please see 'man bb- hosts' for more information.
