Accessing HPCAVE Platform requires credentials. These are sent  by e-mail to users once the accounts are created. For more information conserning opening an HPCaVe account, please consult the dedicated page.

HPCaVe Platform uses SSH ( secure  shell) protocol which allows a secure connection and reduces the risk of data corruption or fraudulent attack.

There are differents methods to connect to the servers depending on the operating system used:

UNIX (Linux / MacOs)

  1. Open a terminal

    To connect from UNIX systems (Linux or MacOS), the preferred method is to use a CLI (Command Line Interface), also known as a Terminal or a Console.

    • For MacOs Users, the CLI is available from the finder under Applications -> Utilities -> Terminal, or from the launchpad by searching “Terminal”.
    • Linux systems will use different CLIs, usually called “Terminal”. They are  located in the accessories panels menu
  2. Login with SSH

    • From the terminal, enter the following command by replacing username with the one sent by e-mail:
    • You may see a warning at your first connection saying that you are trying to connect to an unknown host. You can confidently continue the login process by typing “Y”.
    • The CLI will then prompt you for your password. Type it and press ENTER to continue.
    • Warning: When typing your password characters will not appear on your screen.
    • Once logged in, a welcome message should appear, providing you with various information about the system status, planned maintenance interventions or other important messages.

Caution : Depending on the operating system used  (Mac Os , Linux) you may encounter difficulties to log in and see a message saying  “Remote Host Identification Has Changed

 

 

To get rid of this problem you will need to use the -R option in order to removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts.

i.e : If your remote hostname is “server.example.com” enter:

  • ssh-keygen -R {ssh.server.ip.address} -f {/path/to/known_hosts}

 

Windows

  1. Download a ssh client

    Windows Operating System does not include a built-in ssh tool. You will therefore need to install one of the following ssh clients (Putty,MobaXTerm, CigWin, Kitty, …),  on your computer in order to login.
    If you have already used such a software, please use any ssh client you are already familiar with.

    Otherwise, we recommend MobaXTerm which is more user-friendly

  2. Login from MobaXTerm with SSH

    • Open a terminal by clicking on start local terminal
    • Type SSH and press ENTER to establish a secure connection
    • Enter the following command by replacing username with the one sent by e-mail:

    • You may see a warning at your first connection saying that you are trying to connect to an unknown host. You can confidently continue the login process by typing “Y”.
    • The CLI will then prompt you for your password. Type it and press ENTER to continue.
      Warning: When typing your password characters will not appear on your screen.
    • Once logged in, a welcome message should appear, providing you with various information about the system status, planned maintenance interventions or other important messages.
