使用 Socket 执行远程命令

编写一个程序，实现客户端能在服务端远程执行命令，并把命令结果在客户端打印出来

服务端：192.168.5.131
客户端：192.168.5.134

[[email protected] ~]# cat client.py
#!/usr/bin/env python
#-*- coding:utf-8 -*-

import sys
import tab        # tab模块用于让客户端支持命令tab补齐，需要自己编写该模块，参考：tab.py
import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((‘192.168.5.131‘, 1234))

while True:
    cmd = raw_input(‘Please input command: ‘).strip()
    if cmd == ‘exit‘ or cmd == ‘quit‘:
        sys.exit()
    if cmd:
        s.sendall(cmd)
        data = s.recv(1024)
        print data

s.close()

[[email protected] ~]# cat server.py
#!/usr/bin/env python
#-*- coding: utf8 -*-

import socket
from subprocess import Popen, PIPE

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((‘192.168.5.131‘, 1234))
s.listen(5)
connect, address = s.accept()

while True:
    cmd = connect.recv(1024)
    p = Popen(cmd, stdout=PIPE, stderr=PIPE)
    stdout = p.stdout.read()
    stderr = p.stderr.read()
    if stdout:
        connect.sendall(stdout)
    elif stderr:
        connect.sendall(stderr)

s.close()

先运行 server.py ，然后在客户端执行远程命令：

[[email protected] ~]# python client.py
Please input command: ls
anaconda-ks.cfg
client.py
install.log
install.log.syslog
server.py

Please input command: df
Filesystem     1K-blocks    Used Available Use% Mounted on

Please input command: exit
