Problems with deploying mlat-client with mlat-server

Post by maxspb » Tue Nov 08, 2016 12:39 pm

I've got RTL2838 USB dongle as a receiver and I try to deploy mlat-server with one client just for test. After that I want to deploy 3 more clients. FlightAware's dump1090-fa takes data from the receiver:
and outputs it via port 30005 to mlat-client in beast format. mlat-client is deployed at the same virtual machine with dump1090 and separate to mlat-server. Every time I see about 3 to 7 planes with or without coordinates, so dump1090 receives well. Also I can draw planes with modesmixer2 app, so messages translated through port 30005 are correct.
dump1090 params: dump1090-fa --interactive --net
mlat-client params: mlat-client --input-connect 127.0.0.1:30005 --input-type beast --lat 55.xxx --lon 37.xxx --alt 6 --user maxspb --server 10.10.10.10:9999 --results basestation,listen,8888 --no-udp
mlat-server params: ./mlat-server --client-listen 9999:9999 --work-dir /home/maxspb/work/mlat/mlat-server/work_dir --write-csv csv --basestation-connect 10.10.10.9:8888
After launch, mlat-client stays for a long time in such state:

Code: Select all

Tue Nov  8 14:47:30 2016 Handshake complete.
Tue Nov  8 14:47:30 2016   Compression:       zlib2
Tue Nov  8 14:47:30 2016   UDP transport:     disabled
Tue Nov  8 14:47:30 2016   Split sync:        disabled
Tue Nov  8 14:47:30 2016 Input connected to 127.0.0.1:30005
Tue Nov  8 14:47:30 2016 Input format changed to BEAST, 12MHz clock
And after that it changes to:

Code: Select all

Tue Nov  8 15:02:31 2016 Receiver status: connected
Tue Nov  8 15:02:31 2016 Server status:   ready
Tue Nov  8 15:02:31 2016 Receiver:   11.2 msg/s received 1.4 msg/s processed (12%)
Tue Nov  8 15:02:31 2016 Server: 0.0 kB/s from server 0.0kB/s TCP to server 0.0kB/s UDP to server
Tue Nov  8 15:02:31 2016 Aircraft: 0 of 0 Mode S, 0 of 1 ADS-B used
So nothing goes to server. Please, help me to trace the problem.

Is this about just one client connected to the server?
Is this about standart USB-dongle antenna?
Something configured in a wrong way?

Yours faithfully, maxspb.
P.S. Sorry for mistakes, I'm not a native english speaker.

maybe you should ask the Author of the mlat-server. ;)
