Large broadband ISP called samart in Bangkok are currently installing new network cables for large hotels, and small business's. They require a software program to monitor network traffic so that they can assertain how long a customer has spent on the net and subsequently charge the customer for the use of the network. I have been asked to build the front end for this program, which shouldnt be to difficult. I have choosen to use a DNS/DHCP configured server, running an iptables firewall. We can then take all the packet information and load it into a small XML file so that it can be human readable and so forth printable.
