I have a headless Zero feeding data to Flightaware and FR24 and previously adsbX. My system also has Pi-Hole running.
Checking Pi-Hole today I noticed my Zero was sending data to adsbX that I thought I had cancelled. There is no security issue with this, the cancellation was due to a program setup problem I was experiencing but I am now curious,
HTOP shows the following;
** |_ /usr/bin/socat -u TCP:localhost:50003 TCP:feed.adsbexchange.com:51321**
Neither of the two scripts in my home directory exist, think I recall deleting when I had a program problem but seems socat is still doing something.
I used to submit to adsbX on custom port 51321 but that option disappeared from the adsbX web page.
Has anyone a suggestion as to how I can check if any data is still being submitted and how much?
