FAILLOCK(8)                               Linux-PAM Manual                               FAILLOCK(8)

NAME
       faillock - Tool for displaying and modifying the authentication failure record files

SYNOPSIS


       faillock [--dir /path/to/tally-directory] [--user username] [--reset]

DESCRIPTION
       The pam_faillock.so module maintains a list of failed authentication attempts per user during
       a specified interval and locks the account in case there were more than deny consecutive
       failed authentications. It stores the failure records into per-user files in the tally
       directory.

       The faillock command is an application which can be used to examine and modify the contents
       of the tally files. It can display the recent failed authentication attempts of the username
       or clear the tally files of all or individual usernames.

OPTIONS
       --conf /path/to/config-file
           The file where the configuration is located. The default is /etc/security/faillock.conf.

       --dir /path/to/tally-directory
           The directory where the user files with the failure records are kept.

           The priority to set this option is to use the value provided from the command line. If
           this isn't provided, then the value from the configuration file is used. Finally, if
           neither of them has been provided, then /var/run/faillock is used.

       --user username
           The user whose failure records should be displayed or cleared.

       --reset
           Instead of displaying the user's failure records, clear them.

FILES
       /var/run/faillock/*
           the files logging the authentication failures for users
