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!
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 firstname.lastname@example.org # Use your GT username in place of "someuser3" # press <return> to run # Must be on GT campus internet or connected to Georgia Tech VPN
In addition to "login-phoenix", you may use "login-p" to avoid spelling out Phoenix when connecting. 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 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.
INSERT ENTERING PASSWORD SCREENSHOT HERE
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.
- INSERT SUCCESSFUL LOGIN HERE
- 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.
- In the
HostNamebar, enter your account address:
email@example.com. 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 Phoenix cluster through the terminal.
