After hearing from both Steve and Chester, I finally got around to trying to implement ssh & scp using public/private key authentication instead of password authentication.  I use ssh all the time so I thought it would easy ... not a chance.

Actually, the only thing that I couldn't get from the various man pages was the fact that although the rsa1 standard is the default with ssh-keygen, this doesn't seem to work right out of the box (at least on my box - Red Hat 7.2 kernel 2.4.9-13) ... when I finally thought to run ssh with the "-v" option I saw that ssh was trying rsa2 and dsa, but not rsa1 ... when I re-ran ssh-keygen with "-t rsa" I got an rsa2 key that worked great.

If anyone wants help with this from an amateur, let me know ... I must admit, it is nice to move back and forth from home to work on-line without constantly typing passwords.  Also, ssh makes X11 forwarding really easy ...
