Sir, I m a technical asisstant of a college. Student of the college access internet through a Squid Proxy Cacheing Server. Machines (clients) are limited but everyone want to access internet. If any student sit in one machine, he continuously access internet without thinking of the other student. As a result of that other students fails to get access internet. Is it possible to fix some hours(time) per week/month for each student(user) i,e Quota System. I want a solution such that a student(user) can get some fixed hour(defined in the server) per week. Please help me. Balaram Dey (CSE Dept.) College Of Engineering & Management, Kolaghat KTPP Town Ship Kolaghat, Midnapur (East) West Bengal
