Number of long limit
Hi
Hi! I'm currently using AIX 5.2 and would like to know where can i find to see that there's a restriction on the number of login times a user can have. Example, I want give a 2 login per user but some one to give 3 login and some one have to give unlit login time (without logging off the first one).
i need to restrict user wise login time
i know that in my company, certain users can login several times without encountering "Too many logons" while certain users can only log in once.
any one can help me
thanks

faillog
FAILLOG(8) System Manager's Manual FAILLOG(8)
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.
