Hello out there! Must be something wrong with the spelling (chage)??
RRRolle, there is nothing wrong with the spelling. ‘chage’ is correct. You are changing the aging attributes of the account — when the password expires, how long between required password changes, etc. chage -l will give this information:
# chage -l nagios
Last password change : Sep 17, 2010
Password expires : Nov 16, 2010
Password inactive : never
Account expires : never
Minimum number of days between password change : 1
Maximum number of days between password change : 60
Number of days of warning before password expires : 7
Hi,
I am a new Linux user and I created users and set their password to expire and force them to change password on their first log in, I tried on one user ,it prompted me to enter current password and when i typed current password the screen usually sleeps. Can anyone advise?
very useful tip, thanks alot
One method that is easier than doing the math required by the above solutions is:
passwd -e username
This forces an immediate expiration, and forces a password change on the next login. I use it each time I create a user.
Hope this helps!
Hey, is there a way to configure this so that the operating system does it automatically so an admin doesn’t have to go through all the users and run these commands?
useful answer :)
Thanks
I forgot my password
Very useful
