Using SSH key pairs (e. Secure Shell) is a way of logging into ssh account using a cryptographic key rather than a password.

Instructions:

Windows and Mac and GNU/Linux

When new user requests access via service portal to our HPC centre it’s mandatory to provide a paired public key to complete the user creation process.

Example of creating a key pair with bash:

  1. $ssh-keygen -t rsa
  2. Enter file in which to save the key (/home/user/.ssh/id_rsa):
  3. Enter passphrase (empty for no passphrase):
  4. Enter same passphrase again:
  5. Your identification has been saved in /home/user/.ssh/id_rsa.
  6. Your public key has been saved in /home/user/.ssh/id_rsa.pub.
  7. $cat /home/user/.ssh/id_rsa.pub
  8. Copy and pase the id_rsa.pub key into the service portal order.
