[HTCondor-users] python bindings/bdii problem

[Stephen Jones <sjones@xxxxxxxxxxxxxxxx>]

Hi all,

I have a HTCondor-CE <-> HTCondor setup.

CERN have devised a BDII program for HTCondor-CE. A piece of it is 
below, that I use for testing.The BDII program gets the Collector (the 
one on 9618, by default not the CE one), uses it to get info on the 
HTCondor-CE system, and then constructs another Collector by using the 
default HTCondor-CE port (9619). Then it tries to query the HTCondor-CE 
9619 port Collector to get some facts to publish in the BDII.

Anyway, when I run it, I get an unhandled exception, IOError. I also see 
a message in the /var/log/condor-ce/CollectorLog file:

01/10/19 13:50:19 DC_AUTHENTICATE: required authentication of 
138.253.178.106 failed: AUTHENTICATE:1003:Failed to authenticate with 
any method

So I guess I either need to make the python binding BDII program 
"authenticate" somehow, or make the Collector on the 9619 port not care.

I've tried some things to make that work but it hasn't so far.

Anybody got any tips on the right thing to do?

Cheers,

Ste

ÂÂÂÂÂÂÂ try:

ÂÂÂÂÂÂÂ except RuntimeError:
ÂÂÂÂÂÂÂÂÂÂÂ sys.stderr.write("Unable to locate CE schedd on %s" % ce_host)
ÂÂÂÂÂÂÂÂÂÂÂ continue

if __name__ == '__main__':
ÂÂÂ main()
