Re: [HTCondor-users] condor_write(): Socket closed when trying to write

[john alexander sanabria ordonez <john.sanabria@xxxxxxxxxxxxxxxxxxxxx>]

I saw that message (PERMISSION_DENIED) in the SchedLog file and I solved that issue defining the following macros
Â
ALLOW_ADVERTISE_SCHEDD = $(FLOCK_FROM),$(CONDOR_HOST),$(ALLOW_WRITE),192.168.251.1,192.168.252.1
SEC_ADVERTISE_SCHEDD_AUTHENTICATION = OPTIONAL

Anyway, because I cannot figure out a solution to the flocking problem, right now the FLOCK_TO and FLOCK_FROM have '*' as their value then the condor_write() issue appeared.

Regards,

Â

Did you set the "FLOCK_FROM" macro in the condor_config for each pool?
Doing so then allows the negotiators from other pools to be authorized
to connect to the schedd, and from the looks of your log snippet I think
the schedd on master01 did not authorize the negotiator on master02 and
hung up the connection. (Do you see "PERMISSION DENIED" in the SchedLog?)
