Re: [HTCondor-users] Collector update ads using UDP

[Jaime Frey <jfrey@xxxxxxxxxxx>]

Iâve tried to reproduce this error and have failed so far. Can you send us the configuration of this machine (condor_config_val -summary)?

Hi,

 

This is another report of an issue with v24.0 central managers. In this case, it is probably not a show-stopper.

 

The issue is that UDP classads from peer central managers (in either v23.0 or v.240) are not accepted (thus the other collectors are not known).

 

CollectorLog shows lines like the following:

 

12/07/24 20:16:17 DaemonCore: PERMISSION DENIED for 19 (UPDATE_COLLECTOR_AD) via UDP from host <188.184.103.96:37033> (access level DAEMON)

 

Now, this does not seem an important problem, because it is solved by just using TCP messages.  Historically, we have had both UPDATE_COLLECTOR_WITH_TCP and  UPDATE_VIEW_COLLECTOR_WITH_TCP set as False. It is probably fine if we have the first as True and the second as False (for the subcollectors), i.e. leave the default settings.

 

Still, I guess it's unexpected that these UDP messages are denied in 24.0 but not in 23.0.

 

Cheers,

   Antonio
