[HTCondor-users] Can't use condor_off to stop a Condor.



Hello everyone,
I'm a beginner of condor, trying to set up a cluster and faced some problem.
I'm trying to run the command `condor_off` to stop the condor of a slave server(named compVm2), it said:
SECMAN:2010:Received "DENIED" from server for user unauthenticated@unmapped using no authentication method, which may imply host-based security. Our address was '[an IPV6 address]', and server's address was '[the same IPV6 address as above]'. Check your ALLOW settings and IP protocols.
Can't send Kill-All-Daemons command to local master.
And while I try to stop it on the master machine(named compVm1) with: `condor_off -name compVm2`, an error showed up on the master machine.
Can't connect to master compVm2

Here's How I configure my cluster:
Each machine was named used Host file.
compVm1 has three domain names:
a.execute.potato.computing.private central.potato.computing.private
compVm2 has two domain names:
b.execute.potato.computing.private slave1.potato.computing.private

The master machine(compVm1) was configured with following configuration:
Use ROLE:CentralManager Execute Submit
Another machine(compVm2) used:
Use ROLE:Execute
The two machines share the following config file with Gluster:
CONDOR_HOST = central.potato.computing.private
ALLOW_WRITE = *.computing.private
UID_DOMAIN = computing.private
FILESYSTEM_DOMAIN = potato.computing.private

Both the output of `condor_status` and `condor_q` in line with expectations.
Maybe some of my configuration went wrong, but I can't figure it out, I'll be grateful if you can provide some information about that.

Sincerely
Losses don
