Re: Re: R: [Flightgear-devel] Socket communication
Hi all, Attached you can find the example server I wrote.It should be 'platform independent' but I've tested it only under Windows andCygwin.It might be useful to someone else who has the same problem. I've seen it's a quite recurrent question... I'm goingto use a modified version ofit in my thesis so thanks again.

I don't know anything about it, though. That's probably what you'll want to use. However, until that time when someone pipes in to tell you how to use that, I thought I'd pass along something that might be helpful to you. If you are using a JSBSim aircraft model, you can specify an OUTPUT setion in the aircraft file. See some of the JSBSim aircraft config files for more information on that, or if you are interested and are having problems making it work, as me. The overview is this: if you add these lines into your JSBSim aircraft config file: OUTPUT NAME=localhost TYPE=SOCKET PORT=5678 RATE_IN_HZ 10 /OUTPUT you will get flight data output to the localhost on port 5678. The format of the output is text format, with the first set of data being shipped over being the labels for the data. You can look at the FGOutput.cpp and FGOutput.h files in the JSBSim directory for more information. I've tested this out using the netcat program, nc in my CygWin environment. Open a new console window and try this: nc -l -p 5678 This sets up a listening socket on port 5678. If you run FlightGear with the JSBSim aircraft that has the OUTPUT section in the aircraft config file, you _should_ be able to see the data coming across. I haven't tried this from within FlightGear yet. Good luck. Jon ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

Can anyone tell me which part of FlightGear code deals with socket data communications? Look at the Network subdirectory for all the various options and the mini-docs for a howto. the necessary socket code is built into flightgear and envoked as --native-ctrls=socket,in,32,,5700,tcp where 32 is the data rate (packets/sec) 5700 is the socket address used by the slave and server tcp is the IP protocol (you can use udp, but packert deliver is not guaranteed) Any idea, example, clue or suggestion is appreciated and would be very helpful... Many Thanks in advance RM I want to run flightgear on a computer(slave machine) which has no controls like keyboard, joysticks etc from a machine(server) which has all these controls. Do you plan to run flightgear on the server as well? Otherwise you will most likely have to write or modify some socket code to satisfy the native-ctrls protocol ( see net_ctrls.hxx ) to send the data to the input socket on the slave machine.

Hi All, Can anyone tell me which part of FlightGear code deals with programming of socket communication(which we use for multiple displays)? I want to run flightgear on a computer(slave machine) which has no controls like keyboard, joysticks etc from a machine(server) which has all these controls.
