python实现超简单端口转发的方法


本文实例讲述了python实现超简单端口转发的方法。分享给大家供大家参考。具体如下:

代码非常简单,实现了简单的端口数据转发功能,用于真实环境还需要再修改一下。

复制代码 代码如下:

tcp server

import socket
host = '127.0.0.1' #Local Server IP
host2 = '127.0.0.1' #Real Server IP
port = 6001 #Local Server Port
port2 = 7001 #Real Server Port
def ProcData(data):
return data

add more code....

print "Map Server start from " + host + ":" + str(port) +" to " + host2 + ":"

  • str(port2) +"\r\n"
    server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    server.bind(('127.0.0.1',port))
    print "127.0.0.1 Server start at "+ str(port) +"\r\n"
    client = socket.socket( socket.AF_INET, socket.SOCK_STREAM )
    client.connect((host2,port2))
    print host +" Client connect to " + host2 + ":"+str(port2)+"\n"
    server.listen(5)
    ss, addr = server.accept()
    print 'got connected from',addr
    while 1:
    msg = ss.recv(20480)
    print "Get:"+repr(msg)+"\r\n"
    client.send(msg)
    #print "Client send data %s to "%repr(msg)
    buf=client.recv(20480)
    #print "Client recv data %s from "%repr(buf)
    ss.send(buf)
    print "Send:"+repr(buf)+"\r\n"

希望本文所述对大家的Python程序设计有所帮助。
