本文实例讲述了Python socket套接字实现C/S模式远程命令执行功能。分享给大家供大家参考，具体如下：

一. 前言

要求:

使用python的socket套接字编写服务器/客户机模式的远程命令执行脚本。

serverCmd.py 远程机器上用来执行客户端发送命令的脚本
clientCmd.py 本地机器上,向远程服务器发送命令的脚本
servers.txt  本地机器上,存放所有的远程服务器IP地址文件(仅支持第一个IP)

发送:cmd [command]形式消息,让远程主机执行命令(本地主机无回显)

发送:close session消息,双方关闭会话。

二. 源码

注:

1. 代码注释较少,建议有一定套接字编程基础。
2. 或者直接简单部分修改IP使用。
3. clientCmd.py和servers.txt(修改IP地址后)放在同一目录。
4.程序为简单Demo,仅为学习记录。
