sudo systemctl start shellscript.service
sudo systemctl status shellscript.service
  1. Set up an ssh keypair
  • Generate key pair files
ssh-keygen -t rsa -b 2048

  • Give a different file name like id_vscode

  • Press enter when prompted for a passphrase

    • keys will now be generated in your home directory

  • Open the .pub file that was just created and copy the contents into the clipboard

    • navigate to your remote machine's .ssh > authorized_keys file and paste and save

  • Open your ssh config within vscode (command + shift + P)

    • under the remote's entry in this file, add a IdentityFile field and paste the directory of your private key file after it (e.g., the file with no .pub extension)
