David's submission provided SSH functionality I desperately needed to solve some problems. It was a lifesaver.
I ran into problems connecting my Windows client to the server running on a Mac. I eventually solved the problems by using the public private key mechanism for authentication. I also had to generate the key pair on the Mac and bring the private key across to the Windows machine to get everything to work.
Hatsue was able to figure out things working by doing this:
With administrator help, Enable password authentication. E.g., in case of OpenSSH on Fedora, edit /etc/sshd/sshd_config and change the value of "PasswordAuthentication" to "yes", then send a HUP signal to the daemon so that it re-reads its configuration.
