Generate Key pair on local computer

- Create an sub-folder named .ssh.
- Upload the public key id_rsa.pub to the .ssh folder.
Sign in as an administrator
- Sign in to DSM as an administrator via SSH (refer to this article for detailed instructions, but do not run sudo -i).
- Run a cd command to switch to the .ssh folder you previously created.
- cd ~/.ssh
- Append the public key to a new file by running the command below. There will be two files in the .ssh folder: authorized_keys and id_rsa.pub.
- cat id_rsa.pub >> authorized_keys
