　　　　　　　Python远程连接模块-Telnet(该协议明文传输数据不安全，推荐使用ssh协议)

　　虽然现在主流的python版本还是2.7，相信2020年python程序员都会偏向Python3.x版本的，今天研究了以下网上的telnet程序包，发现挺有意思的，把短连接的代码贴在这，有兴趣的小伙伴可以自行更改，哈哈哈~

 import telnetlib

 def DoTelnet(Host, username, password, finish, commands):

     '''''Telnet远程登录：Windows客户端连接Linux服务器'''

     # 连接Telnet服务器

     tn = telnetlib.Telnet(Host, port=23, timeout=10)

     tn.set_debuglevel(2)

     # 输入登录用户名

     tn.read_until('login: '.encode(encoding="utf-8"))

     tn.write(username.encode(encoding="utf-8") + "\n".encode(encoding="utf-8"))

     # 输入登录密码

     tn.read_until('Password: '.encode(encoding="utf-8"))

     tn.write(password.encode(encoding="utf-8") + '\n'.encode(encoding="utf-8"))

     # 登录完毕后执行命令

     tn.read_until(finish.encode(encoding="utf-8"))

     for command in commands:

         tn.write(('%s\n' % command).encode("utf-8"))

     tn.read_until(finish.encode("utf-8"))

     # 执行完毕后，终止Telnet连接（或输入exit退出）

     tn.close()  # tn.write('exit\n')

 if __name__ == '__main__':

     # 配置选项

     Host = '172.16.96.211'          # Telnet服务器IP

     username = 'yinzhengjie'        # 登录用户名

     password = 'jiubugaosuni'       # 登录密码

     finish = '~]$ '                 # 命令提示符

     commands = ['df -h']            #输入你需要执行的代码

     DoTelnet(Host, username, password, finish, commands)

 #以上代码执行结果如下：
