举例：配置设备作为STelnet客户端登录其他设备（Password认证）

操作步骤

1. 在服务器端创建SSH用户。# 配置VTY用户界面。

   <HUAWEI> system-view
   [HUAWEI] sysname SSH Server
   [SSH Server] user-interface vty 0 4
   [SSH Server-ui-vty0-4] authentication-mode aaa
   [SSH Server-ui-vty0-4] protocol inbound ssh
   [SSH Server-ui-vty0-4] user privilege level 3
   [SSH Server-ui-vty0-4] quit

   # 新建用户名为client的SSH用户，且认证方式为password，密码是YsHsjx_202206。

   [SSH Server] aaa
   [SSH Server-aaa] local-user client password
   Please configure the login password (8-128)
   It is recommended that the password consist of at least 2 types of characters, including lowercase letters, uppercase letters, numerals and special characters. 
   Please enter password:                                      
   Please confirm password:                               
   [SSH Server-aaa] local-user client privilege level 3
   [SSH Server-aaa] local-user client service-type ssh
   [SSH Server-aaa] quit
   [SSH Server] ssh user client
   [SSH Server] ssh user client authentication-type password

   #在客户端Client，配置加密算法、HMAC认证算法、密钥交换算法列表、公钥算法。

   <HUAWEI> system-view
   [HUAWEI] sysname client
   [client] ssh client cipher aes128_ctr aes256_ctr aes192_ctr aes128_gcm aes256_gcm
   [client] ssh client hmac sha2_256 sha2_512
   [client] ssh client key-exchange dh_group_exchange_sha256 dh_group16_sha512
   [client] ssh client publickey rsa_sha2_256 rsa_sha2_512

2. SSH服务器端开启STelnet服务功能，并指定SSH服务端的源接口。# 开启STelnet服务功能。

   [SSH Server] stelnet server enable

   # 指定SSH服务端的源接口。

   [SSH Server] ssh server-source all-interface

   # 配置SSH服务器的公钥算法、加密算法、密钥交换算法列表、HMAC认证算法和最小密钥长度。

   [SSH Server] ssh server cipher aes128_ctr aes256_ctr aes192_ctr aes128_gcm aes256_gcm
   [SSH Server] ssh server hmac sha2_256 sha2_512
   [SSH Server] ssh server key-exchange dh_group_exchange_sha256 dh_group16_sha512
   [SSH Server] ssh server publickey rsa_sha2_256 rsa_sha2_512
   [SSH Server] ssh server dh-exchange min-len 3072

3. 配置SSH用户client的服务方式为STelnet。

   [SSH Server] ssh user client service-type stelnet

4. 配置SSH服务器端新的端口号。

   [SSH Server] ssh server port 1025

5. STelnet客户端连接SSH服务器。# 第一次登录，需要开启SSH客户端首次登录功能。

   开启客户端Client首次登录功能。

   [client] ssh client first-time enable
   [client] quit

   # STelnet客户端Client用password认证方式连接SSH服务器，输入配置的用户名和密码。

   <client> stelnet 10.1.1.1 1025
   Trying 10.1.1.1 ...
   Press CTRL+K to abort
   Connected to 10.1.1.1 ...
   The server's public key does not match the one cached before. 
   The server is not authenticated. Continue to access it?[Y/N]:y
   The keyname:10.1.1.1 already exists. Update it? [Y/N]:n
   
   Please input the username: client    
   Enter password:

   输入密码，显示登录成功信息如下：

   Warning: The initial password poses security risks.                             
   The password needs to be changed. Change now? [Y/N]:n
   
   Info: The max number of VTY users is 21, the number of current VTY users online is 4, and total number of terminal users online is 4.                           
         The current login time is 2023-12-31 11:22:06.                            
   <SSH Server>

   如果登录成功，用户将进入用户视图。如果登录失败，用户将收到Session is disconnected的信息。
