i need a walk through help how to change the port on the piware system…
There are lots of ports involved. What port? What are you trying to achieve?
We would like to change the raw data output port because we have multiple receivers on the same external ip.
piaware itself does not open any listening ports. Do you mean the AVR (“raw”) format output port of dump1090?
You can change that by passing --net-ro-port NNNN to dump1090
How you specify that depends on how you installed dump1090.
