This almost works... On my secondary hobbit server I now have it displaying
correctly again and there doesn't seem to be any errors on that side. On the
main hobbit server I don't see the status for my 64 compute nodes, however they
all show up in the ghost clients list. I figured this wasn't a problem as I can
just add them to the bb-hosts file. If I do this they always change to red
since my main hobbit server tries to query them and cant reach the protected
network.<br>

work. Just reply if it doesn't.<br>
