Dump1090 --net-only

FlightAware ADS-B Flight Tracking

I don’t use the mutability branch, but this is what I got in my /etc/default/dump1090-fa :

#RECEIVER_OPTIONS="--device-index 0 --gain -10 --ppm 0 --net-bo-port 30005"
RECEIVER_OPTIONS="--net-only --net-bo-port 0 --fix"
DECODER_OPTIONS="--max-range 360"
NET_OPTIONS="--net --oversample --phase-enhance --net-heartbeat 60 --net-ro-size 1000 --net-ro-interval 1 --net-http-port 0 --net-ri-port 0 --net-ro-port 30002 --net-sbs-port 30003 --net-bi-port 30004,30104  --net-bo-port 30005"
JSON_OPTIONS="--json-location-accuracy 2"

The other Pi has to have the 30004 and 30104 ports open for listening.

In the rc.local (with execute bit set!) add those:

while true
    do
    	socat -d -u TCP:[source IP]:30005 TCP:127.0.0.1:30104
    	sleep 5
    done &
