Since the spring of 2001, all communication done with UNIX/Linux must be done through a secure channel. Between UNIX/Linux systems, that secure channel is created when using ssh and scp.
The Research Computing Support Group (RCSG) has put together a series of tools people can install on their PCs, to access the UNIX/Linux systems both within NRC, and from the NRC dial-up access.
The tools covered include putty and WinSCP:
It has a wide range of configuration for fonts, colours, behaviour. If you run X on your PC, putty allows the tunnelling of X applications (option must be enabled within putty).
Its basic installation requirement is the download of one executable .exe file, but the full package includes command and batch capable utilities.
More details about those tools, as well as downloadeable modules may be found at
That web page also explains how GUI-based PC FTP tools, how mail tools like Eudora and Outlook, may be safely used, through the secure channel created by SSH.
