使用STelnet V1協議存在安全風險，建議使用STelnet V2登錄設備。
1、生成本地密鑰對
密鑰保存在交換機中單不保存在配置文件中
[Huawei]rsa ?
key-pair RSA key pair
local-key-pair Local RSA public key pair operations
peer-public-key Remote peer RSA public key configuration
[Huawei]rsa local-key-pair ?
create Create new local public key pairs
destroy Destroy the local public key pairs # 銷燬本地密鑰對
[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 # 密鑰對長度越大，密鑰對安全性就越好，建議使用最大的密鑰對長度

2、打開STelnet服務器功能
[Huawei]stelnet server enable
3、配置SSH服務器端口號
[Huawei]ssh server port ?
INTEGER<22,1025-55535> Set the port number, the default value is 22
4、配置密鑰對更新時間
[Huawei]ssh server rekey-interval ?
INTEGER<0-24> Set the interval (in hours), the default value is 0, which means the server will not generate the new key automatically
5、配置SSH認證超時時間
[Huawei]ssh server timeout ?
INTEGER<1-120> Set the authentication timeout, the default value is 60 seconds
6、配置SSH認證重試次數
配置SSH認證重試次數用來設置SSH用戶請求連接的認證重試次數，防止非法用戶登錄。
[Huawei]ssh server authentication-retries ?
INTEGER<1-5> Set the authentication times, the default value is 3 times
7、使能兼容低版本SSH協議
[Huawei]ssh server compatible-ssh1x ?
enable Enable or disable the compatibility with SSH1, the default value is enabled
8、配置SSH服務器的源接口
指定SSH服務器端的源接口前，必須已經成功創建LoopBack接口，否則會導致本配置無法成功執行。
[Huawei]ssh server-source -i ?
<null> Not exists loopback interface/<null>
9、配置訪問控制列表
[Huawei]ssh server acl 2001
10、配置通過SSH登陸的帳號密碼
具體配置見VTY配置
11、配置VTY用戶界面支持SSH協議
[Huawei-ui-vty0-4]protocol inbound ?
all All protocols
ssh SSH protocol
telnet Telnet protocol
12、創建SSH用戶
[Huawei]ssh user ?
STRING<1-64> The specified user name
[Huawei]ssh user 1
Info: Succeeded in adding a new SSH user.
[Huawei]
13、配置SSH用戶的認證方式
[Huawei]ssh user 1 ?
assign Set the key
authentication-type Authentication type
authorization-cmd Authorization mode
service-type Set service type
sftp-directory Set SFTP directory
[Huawei]ssh user 1 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
如果沒有使用ssh user命令配置相應的SSH用戶，則可以直接執行ssh authentication-type default password命令為用戶配置SSH認證缺省採用密碼認證，在用戶數量比較多時，對用戶使用缺省密碼認證方式可以簡化配置，此時只需再配置AAA用戶即可。
14、配置SSH用戶的服務類型
[Huawei]ssh user 1 service-type ?
all Set all service type
sftp Set SFTP service type
stelnet Set Stelnet service type
[Huawei]ssh user 1 service-type stelnet
15、配置SSH用戶按命令行授權，即只能通過命令行使用
[Huawei]ssh user 1 authorization-cmd ?
aaa Set the AAA authorization mode
password認證依靠AAA實現，當用戶使用password、password-rsa或password-dsa認證方式登錄設備時，需要在AAA視圖下創建同名的本地用戶。
如果SSH用戶使用password認證，則只需要在SSH服務器端生成本地RSA或DSA密鑰。
如果SSH用戶使用RSA或DSA認證，則在服務器端和客戶端都需要生成本地RSA或DSA密鑰對，並且服務器端和客戶端都需要將對方的公鑰配置到本地。
16、對SSH用戶進行password、password-dsa或password-rsa認證時在AAA下創建同名用戶名
[Huawei-aaa]local-user 1 password irreversible-cipher 023wg.com
17、對SSH用戶進行dsa、rsa、password-dsa或password-rsa認證時配置方法
17.1、進入RSA或DSA公共密鑰視圖
[Huawei]rsa peer-public-key 023wg.com
Enter "RSA public key" view, return system view with "peer-public-key end".
[Huawei-rsa-public-key]
或
[Huawei]dsa peer-public-key ?
STRING<1-30> Name of the peer public key
[Huawei]dsa peer-public-key 1 ?
encoding-type Encoding type of the remote peer's public key
[Huawei]dsa peer-public-key 1 encoding-type ?
der DER encoded public key # DER編碼的公鑰
pem PEM encoded public key # PEM編碼的公鑰
[Huawei]dsa peer-public-key 1 encoding-type der ?
[Huawei]dsa peer-public-key 1 encoding-type der
Info: Enter "DSA public key" view, return system view with "peer-public-key end"
.
[Huawei-dsa-public-key]
[Huawei-rsa-public-key]public-key-code ?
begin Begin to input public key code
[Huawei-rsa-public-key]public-key-code begin ?
[Huawei-rsa-public-key]public-key-code begin
Enter "RSA key code" view, return last view with "public-key-code end".
[Huawei-rsa-key-code]
鍵入的公共密鑰必須是按公鑰格式編碼的十六進制字符串，由支持SSH的客戶端軟件生成。請將獲取的RSA或DSA公鑰輸入到作為SSH服務端的設備上。

[Huawei-rsa-key-code]
[Huawei-rsa-key-code]public-key-code end
% Fail to decode key string, the key string may be invalid.
[Huawei-rsa-public-key]
17.5、退出公共密鑰視圖
[Huawei-rsa-public-key]peer-public-key end
[Huawei]
17.6、為SSH用戶分配RSA或DSA公鑰
[Huawei]ssh user 023wg.com assign dsa-key 023wg.com
