Re: [Condor-users] condor port problems

[Cole Uhlman <cuhlman@xxxxxxx>]

No, they're the right way around. condor_config has them defined as:
HIGHPORT = 50199
LOWPORT = 50000

And I haven't got any "Sock::bindWithin" messages in any of my logs.

However, "_CONDOR_LOWPORT" and "_CONDOR_HIGHPORT" are not defined in my
env.  Is condor_master supposed to set these environment variables from
condor_config?  Or does the shadow read condor_config and only define
them locally?  Where are they supposed to be set, and is this what the
daemons actually look for?

Thanks
