Re: [HTCondor-users] Failed to send REQUEST_CLAIM to startd

[don_vanchos <hozblok@xxxxxxxxx>]

Hi Zach,

Yes, this is a firewall. There is no direct network visibility from the schedd daemon to the startd daemon.

I use a shared port and CCB mechanism so the startd and the schedd daemons successfully connect to the collector.ÂBut jobs still can't be submitted. My settings are

USE_SHARED_PORT = TRUE

SHARED_PORT_PORT = 9618

UPDATE_COLLECTOR_WITH_TCP = TRUE
BIND_ALL_INTERFACES = TRUE

CCB_ADDRESS = $(COLLECTOR_HOST)

PRIVATE_NETWORK_NAME = htcondor

Maybe I didnât point some setting toÂthe SUBMIT node. How can I configure the schedd daemon? I want the schedd not to connect directly to the startd daemon, but let it use a collector and the CCB to submit job.

Please could you tell me is it possible?

Thanks in advance!

Ivan,

This line from your log seems to be the key:
  condor_schedd[8501]: attempt to connect to <10.7.128.15:49430> failed: Connection refused (connect errno = 111).

The network would not allow the connection to happen to that IP and port. Could it be a firewall/iptables type of issue?


Cheers,
