Parameters
times: Specifies the maximum number of authentication attempts for SSH users, in the range of 1 to 5.
Usage guidelines
You can set this limit to prevent malicious hacking of usernames and passwords.
This configuration takes effect only on the users at the next login.
If the authentication method is any, the total number of authentication attempts (including both publickey
and password authentication attempts) must not exceed the upper limit.
If the authentication method is password-publickey, the server first uses publickey authentication, and
then uses password authentication to authenticate the SSH user. The process is considered one
authentication attempt.
Examples
# Set the maximum number of authentication attempts for SSH users to 4.
<Sysname> system-view
[Sysname] ssh server authentication-retries 4
