Directions from a Windows system.

Without port forwarding.

    SSH does not ship with Windows by default. A third party package must be installed in order to have the ssh client. The SSH client will replace the need of using Telnet into GFDL. Okay, so first off, where to get the client:
    • PuTTY
      • Download PuTTY from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html. Go to the section labelled "Windows-style installer (x86 only) for everything except PuTTYtel", it is half way down the page.
      • Once putty has been downloaded, double click on putty-0.56-installer.exe. This will lauch the installation program. The defaults should be fine. Putty will want to be installed in C:Program FilesPutty, have a link on your desktop, and create a group for itself on the start menu. Putty will then be installed.
    • Cygwin includes ssh and a Xserver for your home computer.
      • http://www.cygwin.com
      • During the cygwin installation, make sure to install ssh.
      • Follow the Linux directions for connecting to GFDL via ssh with Cygwin.
    • Pinceton University has suggestions for various platforms including Macintosh, Linux and Windows) for its users. Be aware, for Windows users Princeton suggests ssh.com's version. This version is only free for certain indviduals (such as University staff). Read the licensing if you go this route.
    • Pay-for packages:
      • ssh.com has a few different versions. There is a free version (for some users -- see the Princeton University note above). There is also their commerical version. The commercial version has extra features.
      • Secure CRT from Van Dyke Software. A very popular package for windows.

    The directions below assume that putty has been installed and is being used. The other windows programs (except cygwin) work in a similar way.
      Click "Start", "Programs", "PuTTY", "PuTTY".
    • You will start on the "Session" Tab:
      • Host Name: Enter Remote Access server name here
      • Protocol: SSH. After selecting this the Port setting should now say 22

      • At the user prompt type in your GFDL user name.
      • Use your token card to generate a one-time password.
      • Type in your one-time password from token card at the password prompt.
      • You are now logged into the remote access server. From here you can ssh or telnet to your destination host.

    Directions from a Macintosh system.

    Macintosh OS/9 or OS/8

    Macintosh OS/X

      Macintosh's OS/X operating system ships with the openssh client.
      • Everything you need should be included.
      • Follow the Linux directions.

    Directions from a Linux system.

    Without port forwarding.

      openssh is the popular, free Linux ssh client.
      Once you have ssh installed on the client then:
      • Log in with the command line ssh (similar to what you would do with telnet):
        • ssh -l username hostname
        • Use your token card to generate a one-time password.
