also, for the location of the log file where you can find records of the items listed, look in /var/adm/. in this directory, you'll find most files you need to look into.

ok, but are not there a default log file locally for this ? am i neccesary obliged to make a script before ?

This is not clear enough. The fact that a password is changed is noted in /etc/security/passwd, a file in stanza format, with a lastupdate= entry. Note that this only pertains to locally authenticated users. LDAP-, Kerberos-, ... -users where the AIX system relies on some external system for the authentication do not have password-information on the system and therefore no pasword-update-information.

You might want to read up about "LAM" ("loadable authentication modules") for details.

That depends on what you want to know. The lsuser command provides information about the attributes "unsuccessful_login_count". "host_last_unsuccessful_login" and some others (issue lsuser root as root for a complete list of user attributes). You can also configure some authentication mechanisms to use the syslog facilities to write logs. There is nothing out of the box, though, because "authentication" is a loadable, configurable and quasi-external service for AIX.

Is logged in the error log. As a root user enter errpt for an overview and errpt -a for a detailed description of every entry (including shutdown/boot events).

ok, thks
I hope this helps.

reboot

reboot(8)						      System Manager's Manual							 reboot(8)

NAME

       reboot - Restarts the machine

SYNOPSIS

       /usr/sbin/reboot [-dlnq]

DESCRIPTION

       When  the  system  is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation.  If no users are
       logged in, use the reboot command.

       The reboot command normally stops all running processes, syncs the disks, logs the reboot,  and	writes	a  shutdown  entry  in	the  login
       accounting file, /var/adm/wtmp.

       The  reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard-
       ware time-of-day clock.	After these activities, the system reboots.  By default, the system starts and the file systems are  automatically
       checked.  If the start-up activities are successful, the system comes up in the default run-level.

       You must have root privileges to use this command.  Using the -n flag can result in file system damage.

FLAGS

       Generates  a  crash  dump  of the system before halting it.  Can be used with any of the other flags.  Does not log the reboot using syslog
       Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not  log
       the reboot using syslog

EXAMPLES

       To  enable  the	default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the
       shutdown, and perform other routine shutdown and reboot activities.  To shut down the system without logging the reboot, enter:	reboot	-l
       This  command  shuts  down  the	system and performs all shutdown and reboot activities, except logging the shutdown.  To reboot the system
       abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes.

FILES

       Specifies the command path Specifies the login accounting file Specifies the path of the syslog daemon

RELATED INFORMATION
