HCNA实验指南-配置STelnet登陆系统

实验内容
使用AR1作为SSH的Server，AR2作为SSH的Client，模拟用户从AR2通过SSH登陆到AR1。
AR1 IP：192.168.1.1
AR2 IP：192.168.1.10
user：admin，password：hello，有管理权限
user：gust，password：nihao，有监控权限

AR1（192.168.1.1），配置如下：

system-view 
[Huawei]sysname AR1
[AR1]rsa local-key-pair create 
The key name will be: Host
% RSA keys defined for Host already exist.
Confirm to replace them? (y/n)[n]:y
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]:
