SSH
To start using the HPC cluster, you'll need to establish a secure connection using SSH (Secure Shell). This guide will walk you through the steps required to connect from a terminal on your local computer.
Prerequisites
- You have been provisioned a VACC account, check here: VACC Dashboard
- You are on-campus or connected to the VPN.
Step 1: Open a Terminal¶
- On Linux, launch a terminal from your applications menu, or by switching consoles.
- On macOS, launch the terminal application from your applications or spotlight.
- On Windows, launch terminal from the start menu.
Step 2: Use the SSH Command¶
Once your terminal is open, enter the following command while replacing your_netid
with your specific NetID.
$ ssh your_netid@login.vacc.uvm.edu
Step 3: Accept the Connection¶
The first time you connect, you may receive a warning about the authenticity of the host. You’ll see something like:
The authenticity of host 'login.uvm.edu (XXX.XXX.XXX.XXX)' can't be established.
ECDSA key fingerprint is SHA256:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
Type yes
to proceed. This adds the cluster’s server to your list of known hosts. This should
only happen the first tim you connect.
Step 4: Enter Your Password¶
After confirming the connection, you'll be prompted to enter your password:
$ your_netid@login.uvm.edu's password:
Type in your netid password. The password prompt will not show characters as you type them for security reasons.
Step 5: Verify Successful Connection¶
Once connected, you’ll see a command prompt that looks something like this:
[netid@vacc-login1 ~] $
This indicates you are now logged in and can start using the cluster's resources.
- Permission Denied: If you see a "Permission denied" error, double-check your NetID and password. Ensure that the password is entered correctly.
Congratulations! You have successfully connected to the Vermont Advanced Computing Center’s HPC cluster.
