Re: [HTCondor-users] python bindings/bdii problem

It may be as simple as putting a proper X509_USER_PROXY in your environment.

Alternatively you can set D_SECURITY log level on the collector side and it will tell you more

about why the authentication is failing.

Subject: [HTCondor-users] python bindings/bdii problem

 

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
