Re: [hobbit] Two DNS lookups for a server but one fails

[Henrik "Størner" <henrik (at) hswn.dk>]

OK, it seems that the bugfix I added in Xymon 4.2.2 had some nasty
side-effects.

I have started work on a 4.2.3 maintenance tree in Subversion, and
there is a new version of the DNS code in it currently. 
http://hobbitmon.svn.sourceforge.net/viewvc/hobbitmon/branches/4.2.3/

You can try out this code (download it from the link above), but it
also involves a change from C-ARES 1.2.1 -> 1.6.0, so you will have
to re-run the configure script to perhaps pick up a new runtime
library that the new C-ARES requires (librt).

I ran it for most of Friday afternoon at work with no obvious bad
effects, so I hope it will work better than the current code.

Xymon still uses ARES to perform the "dns" tests for specific hosts; 
the standard resolver library does not allow you to specify what DNS
server to query. So the --no-ares option only has effect on the DNS
lookups Hobbit performs to determine the IP of the hosts it is testing,
it does not affect the specific testing of a DNS server.
