Hi, I have a Raspberry Pi running Raspbian, and I have configured it as a wifi hotspot using Hostapd and dhcp server. Mobile clients connect to the wifi network and browse internet. I need to keep the track of each user, how much internet data it uses, and also need to limit the user to particular data limit (e.g:1 GB). I need to track data plan, as well how much data used or left for particular user.
Which tool or configuration will allow me to achieve this scenario?
Thanks in Advance.
