[Condor-users] problem with collector

[nini <nini663@xxxxxxx>]

Condor is installed on three FC5 machines.
A couple of days ago, I can successfully submit jobs that runs well.

Today the same job does not even start.
The information from the CollectorLog is like this:


11/1 14:56:16 Housekeeper:  Done cleaning
11/1 14:56:17 NegotiatorAd  : Inserting ** "< nini >"
11/1 14:56:17 attempt to connect to <128.105.143.14:9618> failed: Connection refused (connect errno = 111).

I can not understand why the UPDATE_COLLECTOR_AD need to be sent to 128.105.143.14(condor.cs.wisc.edu).
Is there any place in the configuration that indicate this IP address?

The firewalls of all machines are shutdown. 

Any suggestion?
Thanks,
