Telnet-SSH服务的配置

这狠基础了，介绍就不用提了。

二种认证模式AAA 与 pasword

上拓扑:

要求:
R1与R2互通
2.R1为SSH服务
3.R2为telnet服务
总结

总之狠简单，学校课程是H3C，二个我都做了一遍，命令大致相同，

首先配置IP
R1:
[Huawei-Ethernet0/0/0]ip add 10.1.1.1 24
R2:
[Huawei-Ethernet0/0/0]ip add 10.1.1.2 24

先配置R1上的ssh

//首先配置RSA密钥，1024
[R1]rsa local-key-pair create 
The key name will be: R1_Host
The range of public key size is (512 ~ 2048). 
NOTES: If the key modulus is greater than 512, 
       it will take a few minutes.
Input the bits in the modulus[default = 512]:1024

[Huawei]stelnet server enable   //华为和别的开始SSH的命令不同，注意
Info: Succeeded in starting the Stelnet server.

认证模式就AAA把，
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode aaa
[R1-ui-vty0-4]protocol inbound all   //这一定要配置这条命令，我第一次没配置爆错，ALL 也可以改成别的服务

[R1]aaa
[R1-aaa]local-user admin password cipher admin888
[R1-aaa]local-user admin service-type ssh 
//配置用户admin 服务为ssh
[R1-aaa]local-user admin privilege level 3
 //给用户权限
[R1]ssh user admin authentication-type password  //设置ssh用户
验证

R2配置Telnet 这里使用password密码认证:
[Huawei]telnet server enable 
Info: The Telnet server has been enabled.

[Huawei]user-interface vty 0 4
[Huawei-ui-vty0-4]authentication-mode password 
[Huawei-ui-vty0-4]set authentication password simple admin888	
[Huawei-ui-vty0-4]protocol inbound all 

验证

总结：二种认证模式
