The below can be helpful once you have Orion access (to be done in INF305).

1. Remember to connect to the VPN first.

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

   ssh <your login name>@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 <your login name>@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 <your login name>@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 <your login name>@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.
