[OZAPRS] APRX not connecting to aprsis

[Matthew Cook]

Liz,

The passcode mechanism for the APRSIS servers is not a well kept secret.
So Aprx generates it as needed from your callsign, auto-magically.

I'd suggest that if the radio switched /dev nodes then your rPi USB bus has
either crashed or reset, which would have left it in an inconsistent
state.  You're lucky you can still get in via the ethernet port, since that
is shared with your USB serial.   The USB mechanisms and kernel drivers on
rPi's is well, rather hopeless.

So if you're brave over ssh you can try ;

#sudo reboot

That is about your best remote option for resetting the thing.  Then just
ping your IP and wait, fingers crossed it comes back again.  On a windows
laptop;

#ping -t -w 5000 <your ip here>

Makes M$ ping work a little more like the *nix equivalent.

Once you have reset the rPi USB, the serial converter should enumerate as
the first serial device and be sitting there waiting for you on
/dev/ttyUSB0.  That is until the next time the rPi cracks the sh*ts at you
and resets the USB bus for fun.

For your sanity I'd accelerate the BBB conversion.  My last rPi was
recently changed to a Cubieboard2 (no more serial converters or rPi's yay!)
and I've not looked back.
