Download and install SSH software available here.
For a basic install, just click next or yes to the dialog boxes until the install completes.
You'll now have two new programs installed, "Secure Shell Client" and "Secure File Transfer Client".
Run the program called, "Secure Shell Client".
You'll get a window that looks like the following:
Click on the words, "Quick Connect" in the toolbar.
Enter linux.cs.tufts.edu as the host name.
Enter your EECS login as the user name.
Leave the rest as is.
If you get ask whether or not you want to trust the host your connecting to, as in the below dialog, click yes.
Enter your EECS password and click OK.
You can save these settings for next time by adding a profile.
I use "EECS Shell" as the name of mine.
Then this profile will be accessible from the main toolbar.
Now you should be able to start executing commands as if you're in the lab.
Inside your "Applications" folder is a subfolder named "Utilities."
Inside this folder is a program called "Terminal.app" or just "Terminal".
Run this program.
Enter the following command:
ssh username@linux.cs.tufts.edu
Except replace "username" with your EECS login.
Note that "ssh" is a command line program running on your mac.
Finally enter your password when it asks.
Note: if it asks you about trusting the host with a yes/no question, answer yes.
Updated Note:
In your preferences for the Terminal application (in "Terminal" menu), you may need to change "Declare terminal type ($TERM) as:" to "vt102". See picture below.
