That's correct, the w64 boxes are not in the same subdomain.  winbuild vs build.

I'm trying to monitor them *from* cruncher.  If I do the same lookup from home I get dns resolution and I can ssh to them.

If I can't do this from cruncher then what host on the build network can I use to monitor across subdomains?

What's the first search domain for you at home ? Gonna guess it's build.mozilla.org
The tools should always be using full hostnames - not relying on the host's search domain.

My understanding was that the tool was going to use *.build.mozilla.org CNAMEs to determine the fqdns when necessary, and then generally use the fqdns.
