NAME

       faillog - examine faillog and set login failure limits

SYNOPSIS

       faillog [-u login-name] [-a] [-t days]
	       [-m max] [-pr]

DESCRIPTION

       faillog	formats the contents of the failure log, /var/log/faillog, and maintains failure counts and limits.  The order of the arguments to
       faillog is significant.	Each argument is processed immediately in the order given.

       The -p flag causes failure entries to be printed in UID order.  Entering -u login-name flag will cause the failure  record  for	login-name
       only  to  be printed.  Entering -t days will cause only the failures more recent than days to be printed.  The -t flag overrides the use of
       -u.  The -a flag causes all users to be selected.  When used with the -p flag, this option selects all users who  have  ever  had  a  login
       failure.  It is meaningless with the -r flag.

       The  -r	flag  is  used	to  reset the count of login failures.	Write access to /var/log/faillog is required for this option.  Entering -u
       login-name will cause only the failure count for login-name to be reset.

       The -m flag is used to set the maximum number of login failures before the account  is  disabled.   Write  access  to  /var/log/faillog	is
       required for this option.  Entering -m max will cause all accounts to be disabled after max failed logins occur.  This may be modified with
       -u login-name to limit this function to login-name only.  Selecting a max value of 0 has the effect of not placing a limit on the number of
       failed logins.  The maximum failure count should always be 0 for root to prevent a denial of services attack against the system.

       Options may be combined in virtually any fashion.  Each -p, -r, and -m option will cause immediate execution using any -u or -t modifier.

CAVEATS

       faillog	only  prints  out users with no successful login since the last failure.  To print out a user who has had a successful login since
       their last failure, you must explicitly request the user with the -u flag, or print out all users with the -a flag.

       Some systems may replace /var/log with /var/adm or /usr/adm.
