That's it, what in the name of all that is holy is SSH? It sounds like one logs in on the RPi itself. I have worked with the RPi3B+ building fldigi and wsjt-x, now I am exploring mmdvm and nextion stuff. 73

Aha, like BASH. All is now made clear unto me. Thanks.

Well actually it is not like bash.
Bash is a shell, such as zsh, sh, tsh and so on. SSH is a daemon you connect to to gain access to your system. If you just run ssh daemon on an host you can
- log into that host and gain access to your user's command line shell (bash, zsh, ...)
- transfer files within hosts, with its transfer protocol sftp, scp, winscp, filezilla
- gain access to the window manager (such as Gnome, xfce, kde... ) with the X11 transfer
- create socks tunnels
- create ssh tunnels to redirect remote ports on on local computer and viceversa
In case of pi-star you are mostly using the "log into and gain access to pi-star bash shell (intended as user "pi-star", whose password is "raspberry" of the Pi-STAR system)" =)
