本文主要介绍了python连接telnet和ssh的两种方式，文中通过示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

Telnet 连接方式

				?

									#!/usr/bin/env python

									# coding=utf-8

									import time

									import telnetlib

									import logging

									__author__ = 'Evan'

									save_log_path = 'result.txt'

									file_mode = 'a+'

									format_info = '%(asctime)s - %(filename)s[line:%(lineno)d] - %(levelname)s: %(message)s'

									logger = logging.getLogger(__name__)

									logger.setLevel(logging.DEBUG)

									# 添加记录 记录器功能

									fh = logging.FileHandler(save_log_path, mode=file_mode)

									fh.setLevel(logging.DEBUG)

									fh.setFormatter(logging.Formatter(format_info))

									logger.addHandler(fh)

									# 增加显示 记录器功能

									ch = logging.StreamHandler()

									ch.setLevel(logging.DEBUG)

									ch.setFormatter(logging.Formatter(format_info))

									logger.addHandler(ch)

									def telnet_handle(host='', port=''):

									    handle = telnetlib.Telnet(host, port, timeout=10)

									    handle.set_debuglevel(2)  # Display connect info (send command & received info)

									    logger.debug('Connect host: {} port: {} successful'.format(host, port))

									    try:

									        #获取登录提示‘login：' 后输入密码。

									        handle.read_until('login:', timeout=5)

									        #发送命令 登录，用户名：admin 密码：admin

									        handle.write('admin\n')  #用户名

									        #如果有输入密码的提示符可以打开这一条，并修正确的密码提示符

									        #handle.read_until('输入密码提示符', timeout=5)

									        time.sleep(1)

									        handle.write('admin\n')  #密码

									        time.sleep(1)

									        handle.write('en\n')  #执行指令

									        time.sleep(1)

									        handle.write('sys\n')  #执行指令

									        time.sleep(1)

									        handle.write('display running-config\n')  #执行指令

									        time.sleep(1)

									        handle.write('show stack\n')  #执行指令

									        time.sleep(1)

									        #读取所有信息

									        result = handle.read_very_eager()  

									        logger.info('Received info: {}'.format(result))

									    finally:

									        handle.close()

									if __name__ == '__main__':

									    telnet_handle(host='192.168.10.1', port='23')

ssh连接方式

				?

									#!/usr/bin/env python

									# coding=utf-8

									import paramiko,sys,time

									client = paramiko.SSHClient()

									client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

									#连接SSH服务器

									client.connect("192.168.10.1",22,"admin","admin")

									#执行命令的方式一   连接linux发送固定指令

									stdin,stdout,stderr = client.exec_command("whoami")

									time.sleep(2)

									print(stdout.read())

									stdin,stdout,stderr = client.exec_command("cat /root/lzhi/c_call_python.txt")

									print(stdout.read())

									stdin,stdout,stderr = client.exec_command("ls")

									print(stdout.read())

									stdin,stdout,stderr = client.exec_command("ls -la")

									print(stdout.read())

									#执行命令的方式二  获取命令行参数，并且删除参数1.保留需要执行的命令

									buf = sys.argv

									del buf[0]

									str1 = ' '.join(buf)

									print(str1)

									#执行命令行参数给出的命令

									stdin,stdout,stderr = client.exec_command(str1)

									#time.sleep(1)

									print(stdout.read())
