Using free SSH on different OSes

LinuxFocus: “SSH, the secure shell, is a very good commercial product. However, there are various great free implementations of ssh
clients or servers available for Unix (commercial or free) or for different OSes.
The best known is OpenSSH, available from http://www.openssh.org. From this website you can find alternatives for
Unix systems, Windos, Mac… For some products such as Windos you only have free clients.”
