Have you a script who can do it.

You wish to change all passwords on your system? About only way to do this would be to untrust the system and then trust it again.

# /usr/lbin/tsconvert -r

# /usr/lbin/tsconvert
All passwords will expire for all accounts and then all users will be asked to change their passwords. Either that or you would have to write an expect script to do it.

Is this what your after ?

You just need to use the /usr/lbin/modprpw command, here is the manpage for it;

You can easily write a script to do it on all users, eg;

for i in $(cat )
do
modprpw .... $i
done

where is a file with a list of all your usernames to change.

Thanks Stephan and Michael for your answers,
i think that the modprpw cde could help me.

Best regards,

Stefan,

Can you give the option of modprpw to change a password in a trusted system or can you help to do the script with a file (username:passwd)

Thanks,

Mansour.

Here is a script that reads through a copy of the passwd file with the system users taken out.

It can run the modprpw command pretty easily.
