How to reduce the SSH failed login attempts because of authentication?

Sam

I want to reduce the number of attempts to login into an SSH client from an SSH server to be 2-3. How do I change this is the config file of the server? this is in Ubuntu 16.04

Jakuje

The per-connection value is configured using MaxAuthTries configuration option:

MaxAuthTries

Specifies the maximum number of authentication attempts permitted per connection. Once the number of failures reaches half this value, additional failures are logged. The default is 6.

To set lower, add MaxAuthTries 3 to your sshd_config.
