Hi all,
I have a number of servers that run their own DNS service, each giving out a single IP address. These DNS servers are monitored in bb-hosts like this (names and Ips changed to protect the guilty):
1.2.3.4 dns1.server.com # smtp dns=a:smtp.server.com,ns:smtp.server.com
The issue is that this configuration performs two DNS lookups, one for an NS record for smtp.server.com and one for and A record for smtp.server.com. When run either the NS or the A record is returned but not both. The one that fails shows the following in the web interface:
Service dns on mc20.lon.server.com is not OK : Service unavailable
*** DNS lookup of 'a:smtp.server.com' *** Timeout (channel destroyed)
In this instance it was the A record that failed but in others it is the NS record. I always get one of the queries back successfully, but not both.
These were working fine until I upgraded to Xymon 4.2.2 so this looks like the culprit. Any ideas or suggestions?
