We have a system with a "physics" computer running the simulation at 200 Hz (to simulate servos) and sending a vector of data to a scenery computer. The scenery computer is running Flightgear 2018.1.1 compiled from the "compile" script using Ubuntu 17.10.

Both ends are compiled, but there is a problem with the communications between them. I get the following key messages on the screen:

CHANNEL STRING = SOCKET,IN,120,,5500,UDP OPTION:NATIVE-FDM = SOCKET,IN,120,,5500,UDP ... (and a bit later) Splash screen progress binding-subsystems Entering native_fdm open. Opened channel communication layer. Error reading panel: Failed to open file

(reported by SimGear XML Parser)

CANNOT CONNECT TO SERVER SOCKET ERR = NO SUCH FILE OR DIRECTORY CANNOT CONNECT TO SERVER REQUEST CHANNEL jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock

And the two computers do not communicate.

This seems similar to a problem that showed up with multiplayer operation and seems to involve a mismatch with something in simgear.

Does anyone have an idea how to fix it?

Thank you, Rex du Pont
