Packet Sniffing using Raw Sockets in Linux in C

Solution

You should be using ETH_P_ALL instead of ETH_P_IP as the protocol. ETH_P_IP only listens for incoming IP packets.

Problem

I need to write a packet sniffer in Linux that detects HTTPS packet that are sent and save the url from the request. I found code for this in security-freak and ran it. This code runs and only sniffs the received packet but I need to get the sent packet in the sniffer. How do I get the sent packet in this code? I can't use any library like libcap (forbidden). The code is :sniffer.c
