how to lock user after certain time
 

hello guys, how can one lock an user account after a specific time ?
let's say i want to set locking at 3 days from now, so if the user doesn't log in within 3 days, his account will be automatically locked, if he logs in, his account won't be locked.
i know there are commands like
to lock account immediately or
to set expiration at that time.
but don't know how to set locking after certain time, for example 3 days from now

any suggestions ? thank you

You could try setting the last password change date to date of today minus the maximum password age ('chage -d YYYY-MM-DD <account>') then set the inactivity to 3 days ('chage -I 3 <account>')

look at bash_login

this only works if you use a command login not a graphical login.

You would put a script in .bash_login that would create a file in the users home directory with the date he logged in (if successful}. The script would also have an if statement checking if the last logindate was less than 4 days from 'date' if so update logindate to 'date' else lock account.

Success not a given just my best guess.

ppd

As script would need 'root' authority to lock the account [bad idea]; simply have the script issue the logout command if unsuccessful. Achieves same purpose.

I'd run something like (like as in: I'm just outputting "yup" where you want to actually
lock the user) this from a cron-job every morning ...
