We recommend using Linux as the operative system in your local machine. Other Unix-based systems (such as MacOS) are also widely compatible. Connecting from a pre-Windows 10 machine could be more complex and will need a ssh/sftp client such as PuTTY_ext-link or MobaXterm_ext-link.

Follow the following instructions to log onto our machines from a terminal:

If it is the first time connection, the system will require you a password reset.

The new password must fulfil the following requisites:

  • Minimum of 8 characters.
  • Minimum of 1 capital letter [ A - Z ]
  • Minimum of 1 number [ 0 - 9 ]
  • Minimum of 1 punctuation sign [ . , ; : ? ¿ ! ¡ \  / - _ + * { } ( ) ]


Connecting from Linux / MacOS:

1. Open your terminal and connect to CSUC cluster using your credentials trough the 2122 port and ssh protocol:

ssh -p2122 <youruser>@hpc.csuc.cat

2. Once the connection has been established successfully, a welcome message will print out:
