pwage-hpux-T for Trusted HPUX servers

I'm sharing this in case anybody needs it. Modified from the original solaris pwage script. This modified hpux script will check /etc/password file on hpux trusted systems search /tcb and grep the required u_succhg field. Calculate days to expiry and notify users via email.

original solaris pwage script: https://www.unix.com/shell-programmin...sword-age.html


for the hpux script you need to modify following

/etc/passwd file needs to have a "+email@domain.com" in the description field. You can use '+' or any other symbol but not sure if you can use another ':'

aixguy:*:114:106:aix administrator +aixguy@unix.com:/home/aixguy:/usr/bin/sh
hpuxguy:*:103:106:hpux admin +hpuxguy@unix.com:/home/hpuxguy:/usr/bin/sh
sparcguy:*:112:106:solaris administrator +sparcguy@unix.com:/home/sparcguy:/usr/bin/ksh


MAXAGE=90 <-- we use 90 day expiry policy modify for yours.

Quote:
#! /bin/sh
for i in `cat /etc/passwd | grep \@ | sed 's/:/+/g' | cut -d+ -f1`
do
Quote:
for j in `find /tcb -name $i -exec ls -1 {} \;`
do
LASTPWCHG=`cat $j | grep u_succhg | sed 's/:/#/g' | cut -d# -f3`
DAYSEC=`echo "60*60*24" | bc`
DAWNOFTIME=`/usr/contrib/bin/perl -e 'print int(time)'`
SECSAGO=`echo "$DAWNOFTIME - $LASTPWCHG" | bc`
DAYSAGO=`echo $SECSAGO/$DAYSEC | bc`
done
MAXAGE=90
LEFTDAYS=`echo "$MAXAGE - $DAYSAGO" | bc`

if [[ "$LEFTDAYS" = 7 ]]
then
EMAILID=`cat /etc/passwd | grep $i | sed 's/:/+/g' | cut -d+ -f6`
echo "Your unix id $i will expire in $LEFTDAYS days" | mailx -s "`uname -n` Password aging Reminder" $EMAILID
fi

if [[ "$LEFTDAYS" = 3 ]]
then
EMAILID=`cat /etc/passwd | grep $i | sed 's/:/+/g' | cut -d+ -f6`
echo "Your unix id $i will expire in $LEFTDAYS days" | mailx -s "`uname -n` Password aging Reminder" $EMAILID
fi

if [[ "$LEFTDAYS" -lt 0 ]]
then
EMAILID=`cat /etc/passwd | grep $i | sed 's/:/+/g' | cut -d+ -f6`
echo "Please note that your unix id $i has aleaady expired" | mailx -s "`uname -n` Password aging Reminder" $EMAILID
fi
done
If you want to test modify MAXAGE=0 or 10

do not run against un-trusted hpux boxes

Some points.

The normal secondary delimiter in the /etc/passwd comments field is a comma. Don't try a colon - it will corrupt the passwd file. The "usermod" command should stop you creating an invalid passwd file.

Quote:
cat /etc/passwd | grep $i |
This is a dodgy construct because it can give false matches in any field. In the simple case, consider usernames called "fred", "freda" and "alfred". One extreme case would be a username called "home".
A safer version in the style of your script:
Code:
grep \^${i}: /etc/passwd |

On many O/S the "for i in <open ended list>" construct will collapse when the command line becomes too long for the CLI.


Just for interest in non-trusted HP-UX you can get all the base information for this type of script from the command:
Code:
logins -xto
