SSH into testflight-coda

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

Logging Into Cluster - Linux / Mac

  • To SSH into cluster you MUST be on campus wifi or connected to the gatech vpn

Warning

You must be on GT Campus internet or Connected to Georgia Tech VPN to sign in

Access to PACE Data

  • When you log into testflight-coda, you will not have access to your PACE data that you access from other PACE resources, e.g., Shared clusters (login-s) or Dedicated clusters (login-d).

Warning

For accessing your PACE data on testflight-coda, please use the File Transfer guide.

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

Tip

You can run the command pace-whoami while logged on to the cluster to see all the headnodes you can use.

  • 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.

Windows

  • You can still use SSH on windows, but you will need a client. PuTTy is recommended
  • After you have installed PuTTy, open it and you should see a screen similar to this one.
