Re: [Condor-users] Struggling with Condor Flocking

[Rajesh Rajamani <raj@xxxxxxxxxx>]

Sai,
I think FLOCK_FROM on cm1.mygrid.com must be

FLOCK_FROM = *.mygrid.com

and NOT

FLOCK_FROM = *.hclgrid.com

Please also check that the FLOCK_TO variable is set in the condor config
files of the Schedd Machine.

Also, please make sure that the HOSTALLOW* entries in the config files
are set appropriately.  For details, consult
http://www.cs.wisc.edu/condor/manual/v6.7/5_2Connecting_Condor.html

Let me know if that helps.
