Password authentication enabled Stelnet server configuration example

As shown in Figure 91:

• You can log in to the switch through the Stelnet client (SSH2) that runs on the host.

• The switch acts as the Stelnet server and uses password authentication.

• The username and password of the client are saved on the switch.

The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Press CTRL+C to abort.

The device supports a variety of Stelnet client software, such as PuTTY and OpenSSH. The following is an example of configuring Stelnet client using PuTTY Version 0.58.

To establish a connection to the Stelnet server:

1. Launch PuTTY.exe on the Stelnet client to enter the interface as shown in Figure 92.

2. In the Host Name (or IP address) filed, enter the IP address of the Stelnet server 192.168.1.40.

1. Click Open to connect to the server.

If the connection is successfully established, the system prompts you to enter the username and password. After entering the username (client001) and password (aabbcc), you can enter the CLI of the server.
