Bandwidth Limit User
- by user45611
Hello, i'm saxtor i would like to know how to limit users bandwidth for 10gb per day however i dont want to limit them by ipaddress because if they where to go to an internet cafe the users at the cafe will be restricted with that quota, i need to log them via sockets, example the user request to download a file from http://localhost with there username and password, when they download the file sql will update there bandwidth they used, i have a script here but its not working my buffer doesnt work that rate when a user uses multiple connections thanks for the help!.
