I remember :)  You had the rancid [early version] works, current
rancid can't login problem.

This is a separate issue - I'm looking for an rsh replacement &
"clogin -c cmd" is almost there.
  clogin -c cmd | awk '/cmd/ , /exit/'
does what I want but I tend to not get the "awk /cmd/" part right on
the first try & was wondering if there's an easier / less error-prone
way to get the same effect.


Hi Lee,

Sorry but, as you may noticed, I misunderstood the problem.

I don't know how to help you with that issue, so best of luck :)!
