Just type 'mass password change' into the SEARCH box above and you will find several threads, with scripts to do this for you.

modprpw -E -> to expire a passwd for trusted system

passwd -e, --expire ,to expire a passwd for
non trusted system

cat /etc/passwd | awk '{print $1}' > /tmp/passwd

for i in `cat /tmp/passwd`
echo $i
do passwd -e $i
or modprpw -E $i
done

such a simple shell script may do the trick !!

Hey;

The attached script, mypwd, uses the expect module in perl (which has to be compiled for HPUX). It also assumes direct root access via secure shell/public key authentication.

Just execute it to get a list of options:

./mypwd

Old password must be set
Format: mypwd [ -u ${user} ] -o ${pwd} -n ${new_pwd} -h ${host} [ -f ]

If you specify a '-u' prompt, it'll change the password for that user. It defaults to root. If you specify a -f option, the user will be forced to change their password on their next access attempt.

The scipt works on HPUX, Solaris, and Linux.

So, back to your original question:

for h in $(cat list-o-hosts.txt)
do
for u in $(cat list-o-users.txt)
do
printf "%-8s %s\n" ${h} ${u}
mypwd -u ${u} -h ${h} -o old_passwd -n new_passwd -f
done
done

should do the trick for you.

Hey;

After four tries covering a few hours, I seem to be unable to upload the script. I'll try again tomorrow; but, can't promise that it'll work any better.

Yay! success. apparently, the files have to have an extension on them. Interesting constraint. Any rate, there it is.

Good luck.
