Login restriction/Limitation based on time schedue

This is how to limit a user (in this case, his name is "Joko") to access computer during weekdays and weekends at certain time duration.

1. Edit file

   /etc/pam.d/common-account

   and add a line "account required pam_time.so"
2. Edit file

   /etc/security/time.conf

   and add the following lines to the end of file.

#services  ttys users   times
#
# allow Joko to use computer during weekdays 3 pm-8:30pm OR weekends 9:00am - 9:00pm
* ; * ; joko; Wk1500-2030 | Wk0900-2100

This will not allow joko to login during weekdays before 3 pm or after 8:30 pm or weekends outside 9 am - 9 pm. To disallow certain service, replace '*' in the first entry with a PAM service name (e.g, login, etc.). Files in /etc/pam.d reflect the service names.

On my computer, the following files are the service names can be used:

A good solution to limit use of computer from kids during school days!
