python读取交换机配置做配置备份

通常情况交换机一般会开启telnet或ssh，单独到每个交换机上不一定开启了ftp，所以还是拿常用的来做备份比较方便

python版本要求2.7

要求安装 paramiko包

主函数mainRun.py

#!/usr/bin/python
    # -*- coding: UTF-8 -*-
    
    import paramiko
    import os, sys
    import json
    import time
    import telnetlib
    
    
    def sshconfig(ip, port, username, password, cmd, PS1, isNeedEnableMode, enablePassword):
        # 实例化SSHClient
        client = paramiko.SSHClient()
        # 自动添加策略，保存服务器的主机名和密钥信息
        client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        # 连接SSH服务端，以用户名和密码进行认证
        client.connect(hostname=ip, username=username, password=password, look_for_keys=False)
        chan = client.invoke_shell()
        chan.settimeout(9000)
    
        # 获取登陆后的消息
        welcomeinfo = ''
        while True:
            line = chan.recv(4096)
            welcomeinfo += line
            if (PS1 is not None) & (len(PS1) > 0):
                isFindPS1 = False;

目前这个程序保证用户名和密码对的情况下，还是可用的，没做多少容错处理，后续再进行优化

等这个优化完，后续考虑加上配置变更检测，邮件通知，oss文件上传同步功能。
