Logging On to Phoenix Clusters: Overview¶

Logging on and interacting with Phoenix clusters requires the use of a tool called SSH
Interaction with the Cluster is done through the terminal / command line, and interactive sessions can be started through the terminal after logging in

Log into Phoenix: Using SSH¶

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 Phoenix, you MUST be connected to the GT VPN, even if you are on campus!

Warning

You must be connected to Georgia Tech VPN to sign in.

After you are using the GT VPN, open up a new terminal and simply use this template:

ssh someuser3@login-phoenix.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

In addition to "login-phoenix", you may use "login-p" to avoid spelling out Phoenix when connecting.

Next, you will be prompted for a password. 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.
The screen should look like this:
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.

After you have logged in, you should see a screen that looks like this:

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.

Screenshot

In the HostName bar, enter your account address: someuser3@login-p.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 Phoenix cluster through the terminal.
