DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Usage Guideline The administrator can use this command to specify authentication method for a user. The user name must be a user created by the username command. By default, the authentication method is password. The system will prompt the user to input the password. To authenticate a user via SSH public key authentication, copy the user's public key file to file system. When the user tries to log into the Switch via an SSH client (using the SSH public key method), the SSH client will automatically transmit the public key and signature with the private key to the Switch. If both the public key and signature are correct, the user is authenticated and login into the Switch is allowed. • To authenticate a user via SSH public key authentication via SSH public key or the host-based method, the user's public key file or client's host key file must be specified. Both key files have the same format. A key file can contain multiple keys and each key is defined by one line. The maximum length of one line is 8 Kb. • Each key consists of the following space-separated fields: keytype, base64-encoded key, and comment. The keytype and base64-encoded key fields are mandatory and the comment field is optional. The keytype field can be either be ssh-dss or ssh-rsa. Example This example shows how to configure the authentication method to public key for user user1. Switch# configure terminal Switch(config)# ssh user user1 authentication-method publickey c:/user1.pub Switch(config)# 1431
