OpenSSH is an important tool that keeps the communication and transfer of information between machines secure. Not only does it provide a secure alternative to common tools like Telnet, FTP, and RCP, it can also act as a transport protocol for other services like Subversion, X Windows System, and rsync. This article shows you how to get the best out of the main tools provided by OpenSSH.

I run my window-manager as a child-process of ssh-agent. At startup, the window-manager runs "ssh-add", which invokes an X11 program (ssh-askpass) prompting me for my private key's password. From then on, I can log in to remote hosts using that key, without entering my password anymore (the ssh client programs get the unencrypted key from the ssh-agent via $SSH_AUTH_SOCK). When quitting my window-manager, the ssh-agent also quits and the unencrypted private key is no longer available.
This is a strong combination of ssh-key's security & convenience.
