Re: [go-nuts] golang tcp transport just like nc
Once you've read all of os.Stdin, and the io.Copy finishes, you need to call conn.CloseWrite(), to signal to the other side that it won't receive any more bytes. Otherwise each side is blocked in io.Copy(os.Stdout, conn) waiting for more bytes to arrive from the other side. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
