Extracting Entries from the last 31 Days from /var/adm/sulog

HP-UX SAs:

Could some one please give me some ideas? I need to extract some information for SOX Audit puposes from /var/adm/sulog file. I need to pick a particular user's "su" activities from this file, for the last 31 days. What is the best way to go about?

Thanks for your time, in advance.

It could be done with grep:

grep "user" /var/adm/sylog |grep "07/"

would give you all the entries for "user" for the month of July.

Hi Kennedy:

This should meet your needs. For simplicity, granularity is to whole days (without regard to hours and minutes). The year of the activity is assumed to be the current year, since the 'sulog' doesn't record a date with a year.

# cat ./sulog30
#!/usr/bin/perl
use strict;
use warnings;
use Time::Local;
my ( $fh, $mon, $mday, $time1, $time2 );
open( $fh, '<', '/var/adm/sulog' ) or die "Can't open sulog: $!\n";
$time1 = time();
while (<$fh>) {
( $mon, $mday ) = split "/", (split)[1];
$time2 = timelocal( 0, 0, 0, $mday, $mon - 1, (localtime)[5] );
print if ( ( $time1 - $time2 ) <= ( 60 * 60 * 24 * 31 ) );
}
1;

...simply run as:

# ./sulog30

Regards!

Pete:

I use the grep option normally, myself. However, I am unsure of the output if there are entries for July 2009 and 2008. IF both these exist then my report may turn out to be inaccurate.

James,

I get my output. Along with the output I get this message too:

"Day '29' out of range 1..28 at ./sulog31.pl line 10"

Does this mean that it is providing me with the output for only the last 28 days?

Yes, you will get both. You could search for both this and the previous month. Then "simply" remove the everything up to the current month. Assuming you actually had activity in the previous and current months.

Hi (again) Kennedy:

> I get my output. Along with the output I get this message too:
"Day '29' out of range 1..28 at ./sulog31.pl line 10"

No, this would happen for a February entry in a non-leap-year (as 2009 is). If you have truly not trimmed your 'sulog' since early 2008, then I would expect this to happen.

This is a warning and the remainder of the output is valid within the constraints I have described.

Regards!
