You can connect for the first time to TEMS via SSH from ECGATE:

$> ssh tems

 These set-up steps will allow you to connect to TEMS from other systems, e.g. your workstation or Linux VDI.

Upon logging in, please take a look at the message of the day displayed on the login nodes (or review /etc/motd). 

Password-less access from / to other platforms

If connecting from a different platform into TEMS and to enable password-less connections and transfers between different platforms, you will need to enable ssh key authentication.

  1. Check if you have an existing rsa key pair on ECGATE:

    $> ls ~/.ssh/id_rsa*
~/.ssh/id_rsa    ~/.ssh/id_rsa.pub

    If you don't, you may generate them like so:

    $> ssh-keygen -t rsa                          # press 'enter' 3 more times


  2. Make sure it is added into the different platforms to be used

    If the key was already present in the ~/.ssh/authorized_keys file, it will be duplicated.


    $> ssh-copy-id -i ~/.ssh/id_rsa.pub ecgate
$> ssh-copy-id -i ~/.ssh/id_rsa.pub cca
$> ssh-copy-id -i ~/.ssh/id_rsa.pub tems


  3. Copy also your private key onto those platforms so you can make the connections in both directions:

    $> rsync -av ~/.ssh/id_rsa cca:.ssh/
$> rsync -av ~/.ssh/id_rsa tems:.ssh/
