网工Python之路之paramiko 模块实验（三）读取文件

初始化1.配置hostname 和domain-namehostname  LSW1ip  domain-name  shiranit.com
2.产生密钥，产生1024位的密钥crypto key generate rsa general-keys  modulus 1024
3.配置sssh的信息会话超时时间ip ssh  time-out 120最大认证次数ip ssh authentication-retries 3启用ssh和telnet认证line vty 0 4  transport input ssh telnet   login local
4.本地认证用户 enable passwod 123 username python privilege 15 password 123 PS: privilege 15这么设置是为了免去登陆时输入enable密码
 5.配置管理地址 interface Vlan 1    ip address 192.168.242.11 255.255.255.0
