    NOTES:

    • Accessing HPC must be passwordless unless you have a passphrase during the generating of keys.
    • If you want to use your key (generated using PuTTY) in OpenSSH, check this tutorial on converting PuTTY (.ppk) key to SSH Key.
    • You cannot use your OpenSSH keys to PuTTY and vice versa.

  1. Open Command Prompt or Windows PowerShell.
  2. Type command: ssh <username>@<HPC-Address>ssh username@X.X.X.X
