[Condor-users] gateway

[Masao Fujinaga <fujinaga@xxxxxxxxxxx>]

We are having problems getting jobs submitted from a linux submit host to a windows lab behind a gateway.  On the windows machine, we have errors in the starter log as follows:

0/3 19:10:35 Communicating with shadow <129.128.125.15:37473>

10/3 19:10:35 Submitting machine is "opteron-cluster.nic.ualberta.ca"

10/3 19:12:34 condor_read(): recv() returned -1, errno = 10054, assuming failure reading 5 bytes from <129.128.125.15:55548>.

10/3 19:12:34 ERROR "LocalUserLog::logStarterError() called before init()" at line 205 in file ..\src\condor_starter.V6.1\local_user_log.C

On the submit node, in the shadow log,

0/3 19:16:58 Initializing a VANILLA shadow for job 85.0

10/3 19:19:16 (85.0) (13769): ERROR "Can no longer talk to condor_starter <129.128.237.81:1050>" at line 123 in file NTreceivers.C

We have put in holes in the gateway so that there is communication between the lab and the submit host and the  central manager. We can ping between these machines without any problems and the collector gathers information about the available machines. However, there is something special about the submit-execute communication that seems to be blocked by the gateway. If the gateway is opened up, everything works fine.

Is there anything we can change to condor or to the gateway to make this work?

Thanks for your time.
