SSH into the Cluster

What is SSH?

  • SSH stands for Secure Shell
  • A program for logging into a remote machine securely
  • SSH is how you log into and interact with the cluster

Warning

To SSH into cluster you MUST be on campus wifi or connected to the Gatech VPN

Logging Into Cluster - Linux / Mac / Windows PowerShell

  • Open up a new terminal and simply use this template:
ssh someuser3@login-s.pace.gatech.edu
# Use your GT username in place of "someuser3"
# press <return> to run
# Must be on GT campus internet or connected to Gatech VPN

Tip

If "login-s" doesnt work, you can try "login-s1" through 4. Run the command pace-whoami while logged on to the cluster to see all the headnodes you can use.

  • To get onto the data mover node, use ssh someuser3@iw-dm-4.pace.gatech.edu
  • Next, you will be prompted for a pasword. Enter your GT password. Note when typing passwords in Linux, the password line will be blank and won't show characters. Press enter to login.

Screenshot

  • You should be logged into your account on a headnode. You can now interact with the cluster, submit jobs, make files, and do anything else you would do normally on a computer.

Windows

PowerShell
  • We recommend that you SSH into the cluster through Windows PowerShell
  • To do so, simply type "PowerShell" into the Windows search bar and click on the "Windows PowerShell" application that comes up.
  • This will open a terminal where you can use the instructions from the Logging Into Cluster section above to SSH into the Cluster.
PuTTy
  • PuTTy is an alternative way to SSH into the Cluster if you are unable to use PowerShell.
  • After you have installed PuTTy, open it and you should see a screen similar to this one.

Screenshot

  • In the HostName bar, enter your account address: someuser3@login-s.pace.gatech.edu. Use your GT username instead of "someuser3".
  • Click open and in the terminal type in your GT password when prompted for password.

Note

You may see a warning that looks like this: Screenshot Click "Yes". You can now enter your password. Please note that although you may not see any characters appear when you begin typing your password (this is a security feature), your password input is indeed going through.

  • Congratulations! You are now logged into your account on a headnode and able to interact with the cluster through the terminal.
