Hi all,
I would like to write a program to extract the URLs of websites visited by a system (an IP address) through packet capture.. I think this URL will come in the data section ( ie not in any of the headers - ethernet / ip / tcp-udp ).. ( Such programs are sometimes referred to as http sniffers , i'm not supposed to use any available tool ). As a beginner , I've just now gone through this basic sniffer program : sniffex.c.. Can anyone please tell me in which direction i should proceed..
