Hi,

Could you please try a socket application on Win/Mac(with a Wifi) and see if it connects to the server.

Could I sent you files so you can check they? I can't figureout. On old Air this was worked. If I create ServerSocket with 127.0.0.1 and connect from Socket to 127.0.0.1 using the same PC - this works prefectly. But if I trying to connect from PC A to PC B this not work. (ServerSocket with 127.0.0.1 and Client Socket with 192.168.1.42)

But There is no any issues with WiFi I think. I have local network server - it's work. I can reach this server from any PC that connected to my WiFi. I can see this server from any device from the same WiFi net.

But if I create on PC A - ServerSocket and try to connect to it from PC B using Socket - this not help. #2031 error appear each time.

Firstly I think this is some policy file issue. But I don't think so - PC A don't receive any connection from Client Adobe Air app so I can check something.

Maybe there some issues with ServerSocket because I can use Socket for POP3/SMTP from Adobe Air....

A server socket listening to 127.0.0.1 can only be connected to from a process running on the same machine.

If you want to allow connections from anywhere, listen to 0.0.0.0 instead.

Hi David,

Binding to 0.0.0.0 means binding to all available interfaces/addresses to that machine where as binding to 127.0.0.1 means binding to the loopback interface. The loopback interface should ideally not receive any connection requests from outside but only the local connection directly specifically to 127.0.0.1.

Thanks Nimit,

Yes - this is what I was trying to explain (perhaps poorly) to the original poster, who in reply #2 said:

" If I create ServerSocket with 127.0.0.1 and connect from Socket to 127.0.0.1 using the same PC - this works prefectly. But if I trying to connect from PC A to PC B this not work. (ServerSocket with 127.0.0.1 and Client Socket with 192.168.1.42)"

Clearly the problem in this case is that the ServerSocket on PC B needs to be bound to a non-localhost interface address (or 0.0.0.0) in order for PC A to be able to connect to it.

Cheers,

Dave
