SSH Client for Mac and Windows

What is SSH and why should I use it?

SSH is a replacement for Telnet and Rlogin. SSH has major advantages in terms of security. One of the principal advantages is that your password is encrypted when it is transmitted over the network, not sent in clear text.

Where can I find SSH in ACMS labs?

In Windows XP labs use: SSH "Secure Shell Client", found in the "Communications" folder in "Start" menu, under "Programs".
In Mac OS 9 labs use: MacSSH, found in the "Communications" found in the hard drive.
In Mac OS 10.2 labs use: Terminal, an application native to the operating system, which can be found by going to the hard drive, then "Applications" folder and "Utilities" folder.

Where can I get SSH for my computer?

Various SSH client programs are available on the Internet. ACMS provides recommended SSH client programs that you can download for free and use to log into ACMS Unix hosts. All ACMS hosts support the newer SSH-2 protocol. Some non-ACMS hosts only support the older SSH-1 protocol. If you have a Macintosh and you want to be able to log into both types of hosts you'll need two different SSH programs.

If you use a Mac running OS 10 or above, you can use Terminal an application native to the operating system, which can be found by going to the hard drive, then "Applications" folder and "Utilities" folder. It will bring you to a Unix terminal where you can run SSH.

Select and download the program appropriate for your computer platform.
