I want to have a script to force the users to regularly change the login password on RH 8 , anyone can post the script for me ?
I tried chage , it is great problem , it don't allow two users or above to change password at the same time , it will hold at the below screen , can suggest what is wrong in our system ? thx

login: user2
You are required to change your password immediately (root enforced)

my command is

# chage -d0 userid1
# chage -d0 userid2

But when userid1 is changing the password, then userid2 can't change the password at the same time , we have about 200 users so it is a great problem of us , can suggest how to solve it.

i tried -M0 , but it still have the same problem , it don't allow two users change the password at the same time - when a user hold at the change password screen , then other user can't change the password at the same time , is there other solution ? thx

do you mind posting 1 thread per topic, it makes it much easier for people to keep track of what information you've given, if you feel the replies you get are not helpful or not what you want, then post back explaining your problem in the same thread.
