SSH

Troubleshooting​

Terminal prompts for SSH passphrase instead of GNOME Keyring​

  1. Make sure public key filenames are correct

    Note: Public key filenames should be equal to the private key filename plus a .pub extension, otherwise they won't be picked up by ssh-agent upon login.

    $ ls -1 ~/.ssh/*.pub
    google_compute_engine.pub
    id_rsa.github.pub
    id_rsa.pub

  2. Ensure files and folders have proper permissions

    1. Make sure the .ssh folder has proper permissions

      chmod 700 ~/.ssh

    2. Make sure each private key has proper permissions

      chmod 600 ~/.ssh/id_rsa

      (Do the same for any other private SSH keys in ~/.ssh)

    3. Make sure each private key has proper permissions

      chmod 644 ~/.ssh/*.pub

  3. Set up ~/.ssh/config so the correct private key will be used for a particular host

    Host github.com
        IdentityFile ~/.ssh/id_rsa.github

  4. Log out and log back in

  5. All keys in ~/.ssh should be automatically picked up and added to ssh-agent

    Verify using ssh-add -l or ssh-add -L
