082: What is SSH? What is PuTTY?
SSH, or Secure Shell, is a "terminal" program used to encrypt online communications from end to end, preventing unauthorized access to a data stream. Previous terminal programs, like Telnet, would send username and password credentials over the network in plain text, where they could be intercepted and used by anyone who happened to be watching the server traffic. For better security, CCIT no longer allows Telnet traffic to most CCIT-managed servers.
Users of Linux or Mac OS X enjoy native SSH support in their terminal programs.
Windows users may download the free terminal program PuTTy (http://ccit.mines.edu/CCIT-PuTTy) for similar functionality. For encrypted FTP-type functionality, download WinSCP (http://ccit.mines.edu/CCIT-WinSCP).
