python通过socket发送命令_python 使用socket远程发送命令并获得执行结果详解

#socket_server.py

import socket

import os

import sys

def work():

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

sock.bind(('0.0.0.0',1000))

sock.listen(5)

while True:

try:

conn, addr = sock.accept()

ret = conn.recv(2048)

result = os.popen(ret).read()

conn.send(result)

except KeyboardInterrupt:

print 'Now we will exit'

sys.exit(0)

sock.close()

if __name__ == '__main__':

work()

socket实例化，并且绑定1000端口，持续进行监听，'0.0.0.0'表示监听本地。sock.listen(backlog)表示可同时监听连 接的数量，一般为5。sock.accept()返回(connection,address)，connection通常用来发送和接收数 据，address是客户端的Internet地址。conn.recv(2048)进行接收数据，然后conn.send(result)将结果送回给 客户端。

#socket_client.py

import socket

def socket_send(command):

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

sock.connect(('192.168.1.55', 1000))

sock.send(command)

result = sock.recv(2048)

sock.close()

return result

if __name__ == '__main__':

print socket_send('ls')

sock.connect(address)，里面是一个tuple，IP地址和PORT，发送命令给server，然后用result接收结果并进行return
