#gensio — Public Fediverse posts

Also in that article, I discuss tools like #dar, #kermit, #gensio, and #NNCP that can help you carry data to or from sensitive systems without using a traditional network. Also I mention data diodes (#datadiodes) - hardware devices that let data flow in only one direction. Interesting ideas there. https://changelog.complete.org/archives/10571-how-gapped-is-your-air

I recently started experimenting with #gensio, which can do some really cool things with #serial ports, TCP ports, etc. It can make a serial line a framed, reliable communications medium. It can act like netcat, socat, and so forth. You can use it to run #ssh or #NNCP over a serial line, or provide an encryption layer itself. I wrote up some ideas here: https://www.complete.org/using-gensio-and-ser2net/

RS-422 and RS-485 can also go higher, though it seems that adapters that will go that high are somewhat rare . This one at least https://us.connectiveperipherals.com/products/high-speed-usb-to-rs422-1 seems to go to 10Mbps.

I wonder if there are other high-speed serial (or other) comms methods, probably point-to-point, that don't involve running a full network stack? Simple is good sometimes!

I have also been experimenting with #gensio, which can add reliability and encryption atop serial links. /end

@stevelord @kas Incidentally, a second alternative along those lines would be to use #gensio to provide a reliable connection over an unreliable medium, and then use #nncp's nncp-daemon/nncp-call atop gensio.

I have thought about all this when I've considered running over #LoRA or #XBee SX links. In particular, in xbnet, I documented some #UUCP settings: https://github.com/jgoerzen/xbnet/blob/master/doc/xbnet.1.md#uucp

I haven't directly tried the NNCP-over-UUCP scenario, but I do think it should be fairly straightforward.
