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?

hmm, I don't know what the problem is, the socket stuff there looks correct... will have to wait for someone else to have ideas.

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.

He creates the socket then uses its member functions to setup the connection, but it should work either way. Try something like this: auto inet = new InternetAddress(port); 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. Would need some basic compilable code to know for sure how to make that work in your situation.

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?

It's starting to look like more of a network configuration problem and not a D.learn problem. I'd rather not pollute this forum with those type of issues. Good luck.

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.

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