script help please ..

someone_4 — Tue, 26 Feb 2002 20:42:46 GMT

Hey everyone ..
I am working on an auditing script to see how many times users log in and fail. I am working with the last,lastb, command and the su.log.
With the last commands I am doing
last | grep -v ftp # this is because there are allot of ftps going on and I am not too intrested in them. And I get output like so:
rleon pts/te Tue Feb 26 14:42 - 14:43 (00:00)
rgagnon pts/tc Tue Feb 26 14:29 still logged in
rleon pts/ta Tue Feb 26 14:28 still logged in
bkirk pts/ta Tue Feb 26 13:28 - 13:30 (00:01)
bconvers pts/te Tue Feb 26 11:18 - 11:40 (00:22)
bkirk pts/tg Tue Feb 26 10:47 - 13:21 (02:34)

How can redirect this output to be more of a port type output? For example

rleon still loged in 1
rleon 1
bkirk 2
bconvers 1

And so on. I have been working with awk but I cant get the right output. I know if I can get the right awk santax that I can fix them all to output right.

Thanks
Richard

pipe the output through sort:

last | grep -v ftp |sort

the default behavior for sort is to sort on the first space-delimited field. You can change this, man sort for more info.

The sort command will sort for me .. and with
sort -k 6,6 sulog
or with the
last | grep -v ftp | sort
I can sort buy the users. But I still need a final count of the users. But just a list of the users. I need to turn this:

ajohnson pts/ta Tue Feb 26 08:05 - 08:05 (00:00)
rleon pts/ta Tue Feb 26 14:28 - 15:05 (00:36)
rleon pts/tc Tue Feb 26 15:37 - 15:41 (00:04)
rleon pts/tc Tue Feb 26 15:49 still logged in
rleon pts/te Tue Feb 26 14:42 - 14:43 (00:00)

into this:

ajohnson 1
rleon 4

And so on for all the users that come out with the last command.

Pipe the output of the sort to "cut -f1" then "uniq -c", this will produce a count of each user.

last | grep -v ftp | awk '{ print $1 }' | sort -u | while read name
do
last | grep -v ftp | grep -c "^$name" | read count
echo $name $count
done

That does the trick for counts per user.

(that first line got wrapped - 'while read name' should be together on the first line, 'do' on the second line)

Here's one that does it with the still logged in counts too (simple change).

here's a quick and dirty one I kocked up for an audit over december. I haven't had time to fix it up, but it's a start.

It's for a trusted system.

#!/bin/sh

SCRIPT=${0##*/}
TODAY=$(date)
TMPFILE=/tmp/$SCRIPT.tmp
LOGFILE=$SCRIPT.log

get_users()
{
cat /etc/passwd | cut -d: -f1 > $TMPFILE
}

check_last_login()
{
while read user ; do
LOCKED=`/usr/lbin/getprpw -m lockout $user | sed 's/lockout=//'`
if [ $LOCKED -ne 0 ] ;
then
DISABLED="LOCKED OUT"
else
DISABLED=""
fi
LASTLOGIN=`/usr/lbin/getprpw -m slogint $user | sed 's/slogint=/'$user' /'`
echo "\n$LASTLOGIN\t$DISABLED"
done
}

get_users
echo "USERNAME LAST LOGIN TIME"
check_last_login < $TMPFILE

rm -rf $TMPFILE

Oh my, this would be far too much fuss for me to involve awk or so.
Instead a mere Perl one-liner does this
(might be improvable, since I just hacked it in at the shell prompt)

last|perl -nae '$user{$F[0]}++ unless $F[0] eq "ftp";END{map {printf "%10s%6u\n",$_,$user{$_}} keys %user}'

Hi Richard:

You might consider this:

#!/usr/bin/sh
last|sort -k1| awk 'NF>1 && $2 !~/ftp/ && $1!~/wtmp/ {
if (FIRST==0) {FIRST=1;USR=$1}
if (USR!=$1) {print USR,"ON="ON,"OFF="OFF;ON=0;OFF=0}
USR=$1
if ($7~/still/) {ON++} else {OFF++}
}'

Regards!
