An ''ssh'' connection to the bach servers can be set up both from inside and outside Leiden Observatory, and provides a text-based Linux shell from which commands can be issued. This does not allow for starting any programs with a graphical user interface (GUI). If your own computer is running X-server software (typically the case for MacOS and Linux), a connection which supports GUIs can be started as follows, e.g.: | followed by entering your password.
