Re: [Condor-users] Trouble communicating through GCB servers

[m_kempenaar@xxxxxxxxx]

Thank you for your advice Sonny, I did have a misunderstanding on the
working of GCB.. I've now added a route from both condor systems to the
GCB servers in the other networks and changed the GCB server in the
condor config files.
So condor client in network A connects to GCB in network B and vice
versa and it works!!

Only thing I've noticed is that the condor (both manager and client)
take on the IP address of the GCB server they communicate through. But
that could be because of me not understanding it all to well.

Many thanks!
Marcel.
