[DGD] ssh

[Felix A. Croes]

It looks as if there is going to be a small sourceforge project to
take care of LPC ssh.  Since ssh is going to be almost universally
useful, thanks to the well-developed tool suite that already exists
for it, I thought it would be best to release it in the public
domain and let the community take care of how it evolves.

I have already cleaned up the code a little, and Erwin Harte has
implemented public key authentication.  In this email I'm including
a quick patch, for those who have run into the "hanging
intermittently during key negotiation" problem.

Regards,
Dworkin
