telnet总结:如有漏洞,希望君能评论点出,多谢
telnet分为3类:
aaa AAA authentication
none Login without checking
password Authentication through the password of a user terminal interface
云的创建
增加两个端口
1个本地端口 1个UDP端口 实现云内部的联通
1路由器改名
sys TELNET
2.端口配ip
int g0/0/0
ip add 192.168.0.2 24 (本机ip 为192.168.0.1)
3测试连通性
ping 192.168.0.1
4配置telnet
(1)none Login without checking
user-interface vty 0 4
authentication-mode none
user privilege level 3 //设置权限
(2)password Authentication through the password of a user terminal interface
[TELNET-ui-vty0-4]authentication-mode password (输入密码)
[TELNET-ui-vty0-4]user privilege level 3
(3)aaa AAA authentication
[TELNET-ui-vty0-4]authentication-mode aaa
[TELNET]aaa
[TELNET-aaa]local-user zyn password cipher 123 //增加一个新用户 zyn 密码为123
[TELNET-aaa]local-user zyn privilege level 3 //设置权限
在做telnet实验过程中,遇到password模式没有让设置密码,换了另一款路由器后就可以了,这个可能与路由的型号有关
