For when you have a need to access one Windows box from another using RDP (like from XP to Server 2003, perhaps), and you want to do it securely – tunnel it over SSH.
These are Open-Source tools (not sure about the SSHSecureShellClient – if it isn’t and that bothers you, use PuTTY), so no nag-ware or cripple-ware to deal with. I have not yet used either of these, but will soon start using the PuTTY option. Alternative solutions are nice, however.
Thanks to farmdwg for the OpenSSH link, and to the unknown author of the PuTTY link.
