Dears ,
I have been put into a difficult situation by one of my security
advisors...
whic is that if any one of the user login into the system and logout
within
same minute ( i.e if he logout from system in 45 seconds ) the last
command
could not be able to display the duration of user's session properly
as " last"
command shows ( 23:42-23:42) i.e in hh:mm format.
Now two questions:
1.Is there any way to get the duration of session in seconds?

2.I know how to get the login time in seconds ( lsuser or
/etc/security/lastlog file) but does any body conceive any way to
record the logout time in same way?

SASA

Dears,
Does aybody have some ideas in their minds to solve this problem.

Perhaps look at auditing login and logout events and parsing the audit logs?

Thanks for suggestion!
But the auditing logs once again give the time in same manner ( hh:mm)
I have an idea to write a C program which should be executed in
background
whenever the user logs into the system.
This program will gets the tty device they login on and counts the
seconds until the user logs off the tty.
can anybody help me writing this idea in C or simple shell as i am not
a
C programmer.
I will really appreciate anyhelp in this regard

Instead of a c program that tracks the tty, how about a wrapper
program around the shell. In /etc/passwd call the wrapper that
writes the login time, then calls the shell, then waits for the
shell to exit, then writes the logout time.

Mike

Can any body help me more on writing such a
wrapper for me
It is infact a nice idea , but really appears a difficult one to
implement.

Have you looked at the AIX auditing and accounting? Maybe that would work.

Sasa,

Have a look at the O'Reilly Book "Perl for System Administration".
Chapter 9 (available online as an sample chapter) provides most
of the information needed, including sample code, to write a simple
Perl script to do the necessary.
