[Xymon] Reverse DNS lookup check not working

[SebA]

Thanks Jeremy, that's awesome.  There were no examples for PTR on Xymon out
there so this may help others too.  It works and thanks for the explanation.

Kind regards, 

SebA

I'm not in a position to check until tomorrow, but I'm confident that I
successfully test for the localhost address like so


  DNS=PTR:1.0.0.127.in-addr.arpa


I was wrong in the IP address that I test, but correct in the format and the
fact that it works.  You should be able to do PTR record checks by
formatting in this "in-addr.arpa" format.  An easy way to get this is from
the output of "dig -x" which shows the question section in the
"in-addr.arpa" format (and also in the answer section if it resolves).
