racluster for DNS

Fri Jun 3 16:46:36 EDT 2016

Hmmm, well, to be complete, grab the latest code to make sure we’re working with the same version.  I just uploaded argus-clients-3.0.8.2 to the site.

   http://qosient.com/argus/src/argus-clients-latest.tar.gz 

If that doesn’t work, then we’ll have to fix this as a bug.
