Getting this all working whilst talking someone else through the experimentation and typing sounds hard. I'd start by having autossh(1) on the r-r Pi maintain a SSH connection from r-r Pi through the office router to an Internet SSH server, which may be in your home. The Pi's user account would have a private key with the matching public key installed on the server so no password is required. The password option should also be forbidden on the server. The Pi's .ssh/config would use RemoteForward to forward connections made to a port on the server back across the established SSH connection where they'd pop out to the Pi's SSH server's port. Thus you'd have SSH access to the Pi if you have access to the server and this allows further experimentation, though there's always a risk what you do will break everything. A second Pi acting as the SSH tunnel and future VPN would avoid co-existing with nodogsplash. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2020-07-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
