Hi ,

We have hpux 11iv2 , trusted system , i need to reset password of 50 users , i.e same passwd for all 50 users.

Also it must force them to change their passwords at first login .

Do we have any script for this ??

Hi Zxcv,

You can try to do the above task with a for loop,

1. get the 50 user list from the password file and create a file that will have only the users name: (ex: 50_user_list.txt )

#---------------- Start Script -------

# Script for changing 50 users password , with same password.

for user in `cat 50_user_list.txt`

passwd $user

done

# Forcing passowrd to change at next logon:

for user in `cat 50_user_list.txt`

passwd -f $user

done

echo " Done.."

#---------------------------------- End Script ---------------------------

-While executing this script , writedown the password in the putty screen and select it with the mouse , so that it will be in the buffer, by pressing the right click it will be pasted when it will ask for a password.

-If you select the password from text screen with a carriage return, you dont even need to press enter , just press 50 times right click when prompted for password.

To use a for-loop reading from a file, in a real shell you can do:

for user in $(< 50_user_list.txt); do

For 11iv2 and older, this is undocumented by HP, but still a widely known procedure. (It was listed in HP-UX FAQ documents available in Internet more than 10 years ago.)

Find the hash value. For example, set the desired password to one user on one system, then read the hash value from the user's password file (/tcb/files/auth/<first letter of username>/<username>)

Then replace this line in RAJD1's script:

passwd $user

with this line:

/usr/sam/lbin/usermod.sam -p "<hashvalue>" $user

Replace the string <hashvalue> with the actual hash value.

Correction: <in my first post> in the script

for user in 50_user_list.txt -->

--> should be --> for user in `cat 50_user_list.txt`

Cheers,

Raj.
