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
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:
To log onto Phoenix Cluster:
- To log onto Hive Cluster :
- Use your GT username in place of "someuser3"
- Must be on GT campus internet or connected to Gatech VPN
- 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.
- 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.
- 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 Clustersection above to SSH into the Cluster.
- 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.
- In the
HostNamebar, enter your account address:
firstname.lastname@example.org hive). Use your GT username instead of "someuser3".
openand in the terminal type in your GT password when prompted for password.
You may see a warning that looks like this: 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.
