Usage guidelines
Setting the maximum number of authentication attempts prevents malicious hacking of usernames
and passwords.
If the total number of authentication attempts exceeds the upper limit specified in this command,
further authentication is not allowed.
• For any authentication, an authentication attempt is a publickey or password authentication
process.
• For password-publickey authentication, an authentication attempt contains both a publickey
authentication process and a password authentication process. The server first uses publickey
authentication, and then uses password authentication to authenticate the SSH user.
This configuration does not affect logged-in users. It affects only users that attempt to log in after the
configuration.
Examples
# Set the maximum number of authentication attempts to 4 for SSH users.
<Sysname> system-view
[Sysname] ssh server authentication-retries 4
