Re: [Condor-users] parallel universe and sshd.sh

No, not really : I can't find any $prog in sshd.sh (but found one condor_ssh, maybe you were talking of this one...) : I personnally only added "/bin/" in front of mkdir and sleep, so that it find them :)

But this stills leads me to the sshd server that can't start/listen
