plug timeout w/o Bind

[Derek Olsen]

   David.
   What I've done because I like to use hostname's in my configs instead 
of ip addresses.
   1.  Create a monitor using the check_dns plugin which queries the dns 
server directly by IP address attempting to resolve 1 host in my DNS 
records.
   2.   Setup a master dependency that every service relies on.  So if 
my DNS service goes into a warning/critical/unknown state none of my 
other  serfvices will execute.

   Anyhoo this has worked for me in my particular environment pretty 
well.   In your situation you could setup an check_dns service for each 
of your nameserver entries in your resolv.conf.   Anyhoo this may not 
address your specific needs but I thought i'd share.

    Deet.
