If you’re asked to change the password expiry or password inactivity for a Linux user, the following command will fix it. It’s ideal in situations where you don’t want the password to expire or you don’t want a user to go inactive. It’s also useful if you want a user to be running automated scripts. Here’s the chage command and its available options.
# chage -m 0 -M 99999 -I -1 -E -1 johndoe |
-m 0 will set the minimum number of days between password change to 0
-M 99999 will set the maximum number of days between password change to 99999
-I -1 (number minus one) will set the “Password inactive” to never
-E -1 (number minus one) will set “Account expires” to never.
To validate a user options, run the following:
# chage --list johndoe Last password change : Apr 4, 2018 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7 |
