Logging on to the Grace System

If you are taking cmsc106 or cmsc216 you will need to use a system called Grace (grace.umd.edu). You can view this system as a computer the university provides, where you have been given an account. Your account is represented by your directory id (e.g., terps). The account password is the usual password associated with your directory id.

In order to access Grace you need programs (SSH Clients) that can set up a connection between your computer and Grace so you can log on using your account. Please follow the instructions below that apply to your environment. A quick video for each environment provides an idea of the logging process. Although not the recommended approach, you can also connect to Grace using an SSH Chrome extension (e.g., SSH Chrome Extension).

• PC →
  1. Install MobaXTerm, Home Edition (Free), Installer Edition.
  2. Start MobaXterm.
  3. To connect to Grace:
     • The following video illustrates the logging process ConnectingToGraceWithMobaXterm. Instead of nelsonp, use your directory id.
     • In MobaXterm select "Sessions", "New Session", "SSH".
     • In "Remote host*" enter grace.umd.edu
     • Select the "Specify username" checkbox and enter your directory id (e.g., terps).
     • Select OK (bottom of the window).
     • Enter your password (the one associated with your directory id). After providing the password, you can select "Yes" to store the password.
     • At this point you should be logged on to the grace system. You can now issue commands by typing them next to the prompt (e.g., grace4:~:) and pressing enter. The number that appears after "grace" in the prompt does not need to be 4 (it can be any number).
     • Once you have logged on to Grace, you can test your environment by opening the graphical version of the emacs editor by typing emacs after the prompt. You can close emacs by closing the emacs window.
     • To logout from Grace type logout next to the prompt.

  1. The following video illustrates the logging process ConnectingToGraceWithXQuartz. Instead of nelsonp, use your directory id.
  2. Install XQuartz.
  3. Restart your computer.
  4. To connect to Grace:
     • Start XQuartz.
     • Using XQuartz, open a window by selecting (Applications→Terminal).
     • In the terminal window type the following command to connect to Grace: ssh -Y yourDirectoryID@grace.umd.edu where yourDirectoryID needs to be replaced with your directory id (e.g., terps). The video we provided below relies on -X, but you should be using -Y. Once you are logged on to Grace, you will see the prompt (e.g., grace4:~). You can now issue commands by typing them next to the prompt. The number that appears after "grace" in the prompt does not need to be 4 (it can be any number).
     • Once you have logged on to Grace, you can test your environment by opening the graphical version of the emacs editor by typing emacs after the prompt. You can close emacs by closing the emacs window.
     • To logout from Grace type logout next to the prompt.
