Hello Holger,

This error is because you are using TCP and you don´t have a SERVER application running in the 5555 port, 127.0.0.1 IP to connect with Flightgear.

Two way to resolve:
1 - Make a server app that is running to connect with FG, before you launch the FG;
2 - Change to UDP socket;

Regards,

Thiago Holanda

Hi,

I am testing around with the external protocols and made a simple
defintion in ca file called
"/usr/share/games/FlightGear/Protocol/test.xml":

When I run fgfs and write the data into a file it works
(running with "fgfs --generic=file,out,5,test.dat,test")

But running with sockets I got:

--- cut here ---
$ bin/fgfs --generic=socket,out,5,127.0.0.1,5555,tcp,test
Error reading properties:
Failed to open file

(reported by SimGear XML Parser)
freeglut (fgfs): Unable to create direct context rendering for window
'FlightGear'
This may hurt performance.

Hm. Maybe there has to be a listerner on port 5555?

BTW: I had an error in the XML definition of the protocol and I got a
SIG_FAULT... :-(
