Python:2个套接字，从A发送到B，从B发送到A

Question

我已经为此工作了2天了，但我还是没能让它正常工作。在

我想写一个应用程序，它使用两个套接字，中间有一个介质

这个媒体就是这个脚本，它应该从socketA读到SocketB，从SocketB读到socketA。在

不过，看来我没法搞定。在

我的脚本在运行时接受连接，但它不允许我在telnet屏幕上输入内容。在

我在套接字之间使用2个共享列表来传递数据。在

    s1.bind((HOST,PORT1)) #bind to that port
    s1.listen(2) #listen for user input and accept 1 connection at a time.
    socketArray.append(s1)
    s2=socket.socket(socket.AF_INET, socket.SOCK_STREAM ) #create an INET, STREAMing socket
    s2.bind((HOST2,PORT2)) #bind to that port
    s2.listen(2) #listen for user input and accept 1 connection at a time.
    socketArray.append(s2)
    print "sockets set up"

用了你的密码对我有用。我想你可能做错了是远程登录到了错误的IP地址。不要使用'localhost'或127.0.0.1，你需要使用你的盒子的实际（内部）IP。在

{windows上的{1}如果你能在cd2上看到。在

准确运行代码，无需修改（除了删除顶部的2个未知导入）：

启动脚本：

[ 15:01 jon@hozbox.com ~/SO/python ]$ ./sock.py
sockets set up
launch 1
launch 2
launch 3
launch 4
Writing connections
Writing connections
^CTraceback (most recent call last):
  File "./sock.py", line 93, in <module>
    time.sleep(1)
KeyboardInterrupt

然后电话：

^{pr2}$

{My internal}（我的内部接口^）：

[ 15:07 jon@hozbox.com ~/SO/python ]$ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr **:**:**:**:**:**
          inet addr:10.10.1.11  Bcast:10.10.1.255  Mask:255.255.255.0
