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。

#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。

以上就是python实现超简单端口转发的方法。试一下，你会比你自己想象中的还要强大。更多关于python实现超简单端口转发的方法请关注haodaima.com其它相关文章！
