Re: [HTCondor-users] condor_ssh_to_job issues

[Rolf Seuster <seuster@xxxxxxx>]

re 2, I guess this would be the case if the ControlMaster feature is 
used here. Basically with ControlMaster,
ÂÂÂÂÂÂÂ all subsequent ssh connections to that host go through the same 
connection.

There might be ways to avoid this, but this would come with a penalty. 
That might point you into the
right direction - I never got ssh_to_job to work :(
