determine if user is truly idle
I have a problem. I made a script (that I am very proud of - never scripted before) that kills off idle sessions based on who -u. The problem is it is killing sessions that aren't truly idle. who -u reports them as being idle for 7 hours, when in reality they have been using a program for that entire time. My users all run a separate program when they log in, I believe who -u is looking at tty idle time? As in when the user last entered a command on the command line? Is this true? If it matters, this is AIX 4. Thanks

AUTOLOG(8) System Manager's Manual AUTOLOG(8)
NAME
autolog - Log out idle users
SYNOPSIS
autolog [ options ]
DESCRIPTION
The program reads the utmp file, entry by entry. The username for each 'user process' is compared to the entries in the configuration file
(see autolog.conf(5) ). The first entry to match both the name, the group, and the tty line of the process will be used to conduct the
automatic logout.
CALL
/etc/init.d/autolog start
or
autolog
to run this program in daemon-mode
autolog -o
to run this program as "ordinary" program. Keep in mind: Also when running as ordinary program, it will stay in memory until all
its jobs are done.
OPTIONS
-a (all processes) Print information on ALL utmp entries--not just user processes.
-d (debug mode) This is helpful in setting up your configuration file. The program runs in foreground rather than forking and it
prints out verbose messages about what it is doing.
-n (nokill) Use this to prevent autolog from actually "killing" anyone. Use -d and -n together when setting up a new configuration
file. ( This will not affect killing of lost processes. )
-o (ordinary) Use this to run this program as ordinary program, not as daemon. Program will end, when its job is done. In this case,
some data is kept in "/var/lib/autolog/autolog.data". This is read, when the program is called again.
-f config_file_name
Use this to override the default: "/etc/autolog.conf"
-l log_file_name
Use this to override the default: "/var/log/autolog.log". Note that if this file doesn't exist, no logging will happen. Create the
file (with touch) to enable logging.
-t idle_time
Use this to override the internal default idle time (minutes)
-g grace_period
Use this to override the internal default grace period (seconds)
-m yes/no
Use this to override the internal mailing switch. If "yes" the program will send mail to the users right after killing them.
-c yes/no
Use this to override the internal "pre-clear" switch. If "yes" the program will clear the terminal screen before warning the user.
-w yes/no
Do timeouts based on total session time--not idle time. (hard)
-l yes/no
If set to "yes" activities will be written to the logfile if present.
