1. Remember to connect to the VPN before trying to log onto Orion:

   https://na.nmbu.no/

2. At first, to log in on Orion, you will need to type your password:

   ssh inf205-2024-<your two digits>@login.orion.nmbu.no (or using putty under Windows)

3. When logged in on Orion, do change your initial password to a new one:

   passwd

4. Note that you can copy files from the local system to Orion using scp, for example:

   scp test_file inf205-2024-<your two digits>@login.orion.nmbu.no:~
   
5. You cannot connect back from Orion to your system.
   If you want to collect files from Orion, you need to do so from your local system as well:

   scp inf205-2024-<your two digits>@login.orion.nmbu.no:~/test_file file_collected_from_orion


The following will simplify the login if you have a Linux or Mac system.

6. On Orion, create an .ssh folder, and set its permissions to 700 (i.e., rwx for user only):

   mkdir ~/.ssh
   chmod 700 ~/.ssh

7. On your local system, if you don't have a local ssh key yet (normally, you do), create it using:

   ssh-keygen

8. Make your local public key an authorized key on Orion's login node, by copying it as follows:

   scp ~/.ssh/id_rsa.pub inf205-2024-<your two digits>@login.orion.nmbu.no:~/.ssh/authorized_keys
   
9. On Orion, set the rights for the authorized_keys file to 600 (i.e., rw for user only):

   chmod 600 ~/.ssh/authorized_keys

10. You will now be able to connect using ssh and scp without entering the password.
