[HTCondor-users] Setup of flocking

[Peter Ellevseth <Peter.Ellevseth@xxxxxxxxxx>]

Hi all

 

I am having some issues with setting up flocking on our cluster. We are working with an external supplier to provide some additional computing power in times of need. Our intent was then to establish a separate condor cluster on their infrastructure and use flocking to utilize the additional power. However, I am not able to get the two pools to talk together. I set up the macros on one of our internal schedd-machines and in the general config-files on the external pool (in the config.d folder) as specified here:

https://htcondor.readthedocs.io/en/latest/grid-computing/connecting-pools-with-flocking.html

 

After a lot of back and forth, it is still not working. Initially I got into trouble with authentication, getting error messages like ‘SEMAN: FAILED: Received DENIED:…’

 

In an attempt just to get it running I tried disabling authentication by setting relevant SEC_* macros to NEVER and ANONYMOUS. I am still being told that the two machines are unable to authenticate eachother. Our internal pool is running condor 8.6, while the external instance is running 9.12. Could that be an issue?

 

What would be the preferred method of authentication for this kind of setup? I feel the manual was somewhat short on what is necessary to set up flocking. Is there any supplemental information anywhere?

 

Any tips would be great.

 

Peter
