    思科路由器：开启telnet和ssh远程登陆

    给路由器配置IP

    Router>enable
Router#
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface GigabitEthernet0/0/1
Router(config-if)#ip address 10.1.1.254 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#

    开启telnet配置登陆密码

    Router#enable 
Router#conf te
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#line vty 0?
<0-15>  
Router(config)#line vty 0 3     #3表示3个用户可以同时登陆
Router(config-line)#pass
Router(config-line)#password 123456    #telnet密码
Router(config-line)#login       #允许登陆
Router(config-line)#exit
Router(config)#
Router(config)#enable password feifei    #特权模式密码
Router(config)#
Router(config)#exit 
Router#
