[Xymon] oddness with protocols.cfg

[Clark, Sean]

SooooŠ no way to test xymond with xymonnet, eh? :-D


The issue I had, is I have xymon behind a load balancer, and wanted to be
sure "xymon" is up and not just that port 1984 is listening

The xymon ping in protocols.cfg looked perfect but commented outŠ. Now I
see why
