SSH and OpenSSH are essential security tools for today’s communications. The widespread use of wireless networks that require authorization via authpf means that you need to run an SSH client on every machine you connect to such networks.

Here’s a list of places to get you started:

• Microsoft Windows: PuTTY
• Microsoft Windows: Other SSH clients
• Mac OS X: you have the Terminal (Macintosh HD::Appl
  ications::Utilities), use command-line SSH tools from there.
• Mac OS X: don’t like the command line? Maybe JellyfiSSH will be the thing?
• Mac OS 9: MacSSH
• Palm OS: pssh
• Pocket PC: PocketPuTTY
• Microsoft Windows CE: OpenSSH CE
