Hi All, I want to set 2 hours to limit my staffs to access internet everyday, After my staff login, i can see that the login time, mac address in the “user accounting” table, once the staff access internet over 2 hours they can not access internet again, but the record keeping in the “user accounting” table, if i “remove” the staff list in the table they can access internet again, i try to find some way to set remove that automatically but the “user accounting” table only can remove by manually. Anyway can remove that by automatically everyday?? Or any script can make it automatically to remove the “user accounting”???? Thanks!!!!
