It's starting to look like more of a network configuration

not a D.learn problem. I'd rather not pollute this forum with 
those

type of issues. Good luck.


I'll do my best.

Thank you.

Is there any particular reason to use 0.0.0.0 creating your
InternetAddress?  I think it should be the ip of your server
or just send port and ADDR_ANY will be used.

From Wikipedia:

In the Internet Protocol version 4 the address 0.0.0.0 is a 
non-routable
meta-address used to designate an invalid, unknown or non 
applicable

target.


Thank you for your reply!
I thought ADDR_ANY is the same as 0.0.0.0,so I used it.
This Server doesn't know ip of opponent client.
I tried rewriting code with using ADDR_ANY, but do not work...

Try something like this:

Oh,I'm sorry.
I forgot writing I already tried above instance.

The constructor for class InternetAddress will set addr to 
ADDR_ANY.
This should work if your server and client are on the same 
machine.

Otherwise you need to set the address to the IP of your server.


When my server and client are on the same machine,these succeed.
If I try communicating with other machine via global network,it 
do not work.

IP of my server which you say above should set to server side?

This is just a guess, but it is because you're setting the 
socket to be blocking after the call to accept? If it defaults 
to non-blocking, this would cause accept to return immediately, 
so the client connecting would fail as the server isn't 
currently accepting connections. Also to verify it's not a 
firewall issue, for connecting try using 127.0.0.1.


Thank you for your reply:)

Seeing your reply, I try commenting client.blocking(true) out,
but it do not work.

My server and client do work using 127.0.0.1,
So ,maybe I think firewall setting is correct.

Server is not active?

I tried making simple chat program with std.socket.
On starting programs,client program stops.
SocketOSException was caught ,so I checked errorCode().
Win7,which I use,tells me error code 10061.
I surely think to start server program,
and I allow fire wall to connect...

Is there any possible causes else?

Thank you for your reply.
I'll think it over　again.
