Re: [HTCondor-users] condor_q and condor_status filter

[Todd Tannenbaum <tannenba@xxxxxxxxxxx>]

Hi Werner,

It may help to know what platform you are using, in particular are we talking Linux, Windows, or Mac?

I did not test this idea, but some quick thoughts: 

Perhaps if you set DEFAULT_DOMAIN_NAME in your condor_config  on all the machines in your pool to be the same (i.e. the same name as used on your original hosts)?  This way all slots will report the same domain name in their classad, and perhaps everything will work the same regardless of if your machine is inside or outside your domain.  Again, I didn't test this idea myself, but just a thought...  Another (untested) thought would be to try using the "NO_DNS=True" option in the config file.  Both of these knobs are documented in the manual.

regards
Todd

Hi,

We were already using HTCondor in a network within a domain. Now we add computers outside of the domain.

I often used condor_status with hostname to list only the slots of this machine.

It doesn't work with the new computers.

"condor_status 25081PC" from a machine inside the domain doesn't return anything.

By using "condor_status 25081PC -diagnose" I see the domain will be added to the hostname.

"Arg1 (25081PC) --- adding contraint[Name=="25081PC.eal.jku.at" || Machine=="25081PC.eal.jku.at"]"

"condor_status slot1@25081PC" works. The domain will not be added.

How can I prevent the domain from being added and use the given hostname?

In a network without domain and DNS, I get the error
"condor_status: unknown host"

How can I force, only use the hostname for the collector-query?

I have the same problem by trying reach a queue from a other machines with "condor_q -name" or "condor_rm -name"

"condor_q -name 25081PC" returns "Error: Collector has no record fo schedd/submitter"
"condor_rm -name 25081PC -all" returns "Error: cannot get address of schedd 25081PC.eal.jku.at"

In the network without domain and dns, it returns "Error: unknown host"

Do anyone know how I can reach the hosts which are not in the domain?

Thanks for suggestions,

Werner
