/var/log/faillog is a log file for failed login attempts. This file maintains a count of login failures and the limits for each account. The file is fixed length record, indexed by numerical ID. Each record contains the count of login failures since the last successful login; the maximum number of failures before the account is disabled; the line the last login failure occurred on; and the date the last login failure occurred. Since data is in binary format you need to use faillog command to display failed login attempt.


How do I use faillog?

To display failed login attempt for user root with following command:
$ faillog -u root
Output:

Login       Failures Maximum Latest                   On
root            0        0   02/17/06 14:49:52 +0530  tty1

To display all failed login attempt try:
$ faillog -a
Output:

Login       Failures Maximum Latest                   On
root            0        0   02/17/06 14:49:52 +0530  tty1
rocky           0        0   02/27/06 22:05:03 +0530  tty1
usr1            2        0   02/16/06 15:05:01 +0530  tty2

  1. I created a user and deliberatly made its login faild.
    When I use the command ,it doesn;t seem to work.
    I even checked the /var/log/faillog file and its empty…

  2. It seems like /var/log/faillog doesn’t create at the installation time.

    Do we have any other way to get the status of the user account ?

  3. faillog command not found in RHEL-7. is there any other way to find out the failed attempt log in RHEL-6 or RHEL-7
