Accessing the Cluster - mghpcc-projects/c3ddb GitHub Wiki

All access to the c3ddb is done through SSH (Secure SHell) client. SSH instructions will vary based on your operating system, but all systems will require your private SSH key downloaded when you submitted a request and your passphrase.

Connecting to the SCC from Microsoft Windows There are multiple SSH clients available for Microsoft Windows, each will connect to the SCC using the same protocol. These instructions are based on MobaXterm because this application provides functionality you may find useful for other tasks.

Using MobaXterm to Connect to c3ddb:

1. Download and Install MobaXterm. You can also watch this MobaXterm Demonstration Video.

2. Launch MobaXterm and start a “New Session”:

3. Select “SSH” as the session type:

4. Specify “c3ddb01.mit.edu” as the remote host and click “OK”:

5. Your connection will be saved on the left sidebar, so the next time you can start your session by clicking the “c3ddb01.mit.edu [SSH]” link. In the terminal window you will get a prompt to enter your login information and password (Note that the characters in your password will not be displayed when you type them as a security precaution):

6. Alternatively, open the MobaXterm terminal and type:
   ssh -i /path/to/sshkey -l {username} c3ddb01.mit.edu

7. Enter passphrase when prompted.
