Re: [Condor-users] condor_status -direct hostname : why can't I use IP number instead of hostname?

[Steven Timm <timm@xxxxxxxx>]

What is the output of condor_status -l | grep -i name

That will tell you what the name of your startd's are
and what name will work in condor_status -direct.
It all depends on the daemon name.
On a multi-slot machine, the same startd can be accessed
by any of slot1@host, slot2@host, and give info for all.

condor_status -direct 23-4 should work too.

IP numbers don't work because they have nothing to do
with daemon names.

Again, condor_status -direct has very limited use.
I had used condor for 4 years and this is the first I had
ever heard of it.
