模拟ssh远程执行命令-代码实现

服务端：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import socket
import subprocess

phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
phone.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR,1)    # 端口复用
phone.bind(('127.0.0.1', 8090))
phone.listen(10)
while True: # 连接循环
    connt , client = phone.accept()
    print('starting ....')
    print(client)

    while True: # 通信循环
        try:
            # 1.收到命令：
            cmd = connt.recv(1024)
            if not cmd :continue   # 适用于Linux 操作系统

            # 2.执行命令：
            ojb = subprocess.Popen(cmd.decode('utf-8'),shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)

            # 3.返回命令结果给客户端：
            stdout = ojb.stdout.read()
            stderr = ojb.stderr.read()
            connt.send(stdout+stderr)
        except  ConnectionResetError:       # 适用于windows操作系统
            break

    connt.close()
phone.close()

 

 

客户端：

 

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import socket

phone1 = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
phone1.connect(('127.0.0.1',8090))
while True:
    cmd = input('>>>:').strip()
    if not cmd:continue
    phone1.send(cmd.encode('utf-8'))
    data1 =phone1.recv(1024)
    print(data1.decode('gbk'))     # windows 默认编码是gbk linux 默认编码是 utf-8

phone1.close()
