Stelnet（安全telnet）登陆也成为shh（sercure shell,安全外壳）登陆
———–必要配置—————
1、先根据加密算法生成秘钥对,用于传输数据时加密保护，保存在交换机中但不保存在配置文件中
[Huawei]rsa local-key-pair create
或
[Huawei]dsa local-key-pair create
举例：
[Huawei]rsa local-key-pair create
The key name will be: Huawei_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 #设置密钥位数

#客户端登陆SSH server服务端后自动获得分配钥匙
2、打开设备SSH（stelnet）服务端功能
[Huawei]stelnet server enable
3、创建SSH用户并指定其登陆验证方式
[Huawei]ssh user sshtest authentication-type ?
all Any authentication mode, any one of password, RSA, and DSA
dsa DSA authentication
password Password authentication
password-dsa Both password and DSA authentication modes
password-rsa Both password and RSA authentication modes
rsa RSA authentication
4、设置SSH用户服务类型
[Huawei]ssh user sshtest service-type ?
all Set all service type
sftp Set SFTP service type
stelnet Set Stelnet service type
当通过password、password-dsa、passowrd-rsa认证时，需要在AAA视图下创建同名本地用户，并设置其服务类型和级别
5、配置参考如下
[Huawei-aaa]local-user sshtest password cipher 123456
[Huawei-aaa]local-user sshtest service-type ssh
[Huawei-aaa]local-user sshtest privilege level 3
当通过DSA、RSA认证时，需要在服务器端和客户端都生成本地RSA或DSA密钥对，且在服务器端和客户端都需要将对方的公钥配置到本地。
具体配置，一般很少用
6、配置对端RSA或DSA 公钥名并进入公钥编辑视图（以RSA为例）
[Huawei]rsa peer-public-key 001
Enter “RSA public key” view, return system view with “peer-public-key end”.
[Huawei-rsa-public-key]
7、开始输入编辑公钥秘钥[1]
[Huawei-rsa-public-key]public-key-code begin
[Huawei-rsa-key-code] A8268E05 56254CD1 D73FA4C6 2356FFFC 0567C814
[Huawei-rsa-key-code] 5EB8CE45 83B18D2A 9A90B558 0A260DD5 49B4CA18
……………………….
8、完成公钥秘钥编辑并退出返回到公钥视图
[Huawei-rsa-key-code]public-key-code end
[Huawei-rsa-public-key]
9、返回系统视图
[Huawei-rsa-public-key]peer-public-key end
[Huawei]
10、为用户分配存在的公钥
Ssh user user-name 001
———–可选配置————-
1、SSH服务器可选配置
[Huawei]ssh server ?
authentication-retries Set the authentication times #SSH登陆重试次数，防止非法登陆
compatible-ssh1x Set the compatible ssh1x #设置ssh兼容低版本ssh协议
port Set the port attribute #修改ssh服务器端口（默认22）
rekey-interval Set the interval generated by the SSH sever key #配置SSH 密钥的更新周期
timeout Set the authentication timeout #设置ssh验证超时时间(多长时间为登陆成功则断开)
Ssh server authentication-retrieves
2、为指定的SSH用户配置按命令行授权[2]
[Huawei]ssh user xia authorization-cmd aaa
