HCNA实验指南-配置路由器开启SFTP

实验内容
使用AR1作为SFTP的Server，AR2作为SFTP的Client，模拟用户从AR2通过SFTP登陆到AR1。
AR1 IP：192.168.1.1
AR2 IP：192.168.1.10
user：admin1，password：admin1，有管理权限

AR1（192.168.1.1），配置如下：

<Huawei>syste
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[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]:
