In Linux, the “faillog” command is used to display and manage records of login failures. The faillog command reads and displays information from the file /var/log/faillog, which stores the information about failed login attempts.
Here’s how to use the faillog command to display records of login failure:
- Open a terminal and log in as root or a user with sudo privileges.
- Run the “faillog” command with the “-a” option to display all the records of login failures:
faillog -a
This will display a list of all failed login attempts, including the user’s name, the terminal, the date and time of the attempt, and the number of failed attempts.
- To display the record of login failures for a specific user, run the “faillog” command with the “-u” option followed by the username:
faillog -u username
This will display the record of failed login attempts for the specified user.
- You can also use the “faillog” command to set the maximum number of login failures and the lockout time for a user. For example, to set the maximum number of login failures to 5 and the lockout time to 30 minutes for a user:
faillog -m 5 -l 30 -u username
This will set the maximum number of login failures to 5 and the lockout time to 30 minutes for the specified user.
By using the faillog command in Linux, you can easily display and manage records of login failures for users on the system.
