Hi Joseph >@2007.03.05_18:01:28_+0200

Thanks for some sane considered advice.

> Have you tried using the command line windows client?

No. Will do so. Never installed it before. First pass it says "Can't
create tunnel: The system cannot find the file specified"

Since that's not too informative I'm guessing it is looking for an ssh
client. Now to figure how to tell it to use what's installed...

This info most welcome...

Neither appear to be.

I assume its using the plink which comes with Putty.
