Sockets issue

[okibi]

I'm a bit puzzled here. I'm trying to get my sockets working, but it only connects once. Here is my code:

server.d:
auto soc = new TcpSocket();
soc.bind(new InternetAddress("localhost", 10101));
soc.listen(10);
Stream str = new SocketStream(soc.accept());
while(true)
{
	char[] line = str.readLine();
	if (line !is null)
		cmdOpen(line);
}

client.d:
Socket socket = new TcpSocket(new InternetAddress("localhost", 10101));
Stream stream = new SocketStream(socket);
stream.writeString(args[1]);
socket.close();

Can anyone point out what I'm doing wrong? The first connection works fine, but any connection afterwords fails (line IS null on second connection).

Thanks!
