Objective

The objective of this document is to help configure the Secure Shell (SSH) Server User Authentication Settings on Sx500 Series Stackable Switches. These settings also help if you want to add a new SSH user. It is an optional setting.

Note: Before you can add a user, an RSA or DSA key should be generated for the user through an external SSH key generations/client application.

Applicable Devices

• Sx500 Series Stackable Switches

Software Version

• v1.2.7.76

Secure Shell (SSH) User Authentication

Step 1. Log in to the web configuration utility and choose Security > SSH Server > SSH User Authentication. The SSH User Authentication page opens:

Step 2. In the SSH User Authentication by Public Key field, check the Enable check box for authentication to be performed on the SSH client user.

Step 3. Click Apply.

The SSH Server User Authentication Table has the following fields:

• SSH User Name — The user name of SSH user is displayed.

• Key Type — The key type is displayed which are either RSA or DSA.

• Fingerprint — The fingerprint generated from the public keys is displayed.

Step 4. Click Add to add a new SSH user. The Add SSH User window appears.

Step 5. In the SSH User Name field, enter the SSH User name.

Step 6. In the Key Type field, click the radio button of the desired key type.

• RSA — It is an algorithm used for both encryption and signatures.

• DSA — It is an algorithm used for only signature.

Step 7. In the Public Key field, enter the public key generated by the SSH client application.

Step 8. Click Apply. The new SSH user is added.

Step 9. (Optional) To edit SSH username credentials, click the desired check box and click Edit. The Edit SSH User window appears.

Step 10. Click Apply after the necessary changes made.

Step 11. (Optional) To delete SSH username, check the desired check box in the SSH User Authentication Table and click Delete to delete.
