The ssh user assign command assigns an existing public key to a user.
The undo ssh user assign command deletes the mapping between the user and public key.
By default, no public key is assigned to a user.
ssh user user-name assign { rsa-key | dsa-key | ecc-key } key-name
undo ssh user user-name assign { rsa-key | dsa-key | ecc-key }
| Parameter | Description | Value |
|---|---|---|
| user-name | Specifies the SSH user name. | The value is a string of 1 to 64 case-insensitive characters without
spaces.
NOTE:
The string can contain spaces if it is enclosed with double quotation marks ("). |
| rsa-key | Specifies an RSA public key. | - |
| dsa-key | Specifies a DSA public key. | - |
| ecc-key | Specifies an ECC public key. | - |
| key-name | Specifies the client public key name. | The value is a string of 1 to 30 characters. |
Usage Scenario
When an SSH client needs to log in to the SSH server in RSA, DSA, or ECC mode, run the ssh user assign command to assign a public key to the client. If the client has been assigned keys, the latest assigned key takes effect.
Precautions
The newly configured public key takes effect upon next login.
If the user named user-name to whom a public key is assigned does not exist, the device automatically creates an SSH user named user-name and performs the configured authentication for the SSH user.
To improve security, it is not recommended that you use RSA or DSA as the authentication algorithm.
