Consider this post as Building your own tools with Scapy & Python part 2. Our first step in sniffing the Wi-Fi network is obtaining the MAC address of the Amazon Dash Button, because you don’t want register a button-press every time your friend comes over and connects to your Wi-Fi. Run Scapy with root priviledges. The server is listening on port 443, and all communication will be done through the loopback device. The filter parameter is used for better performances on high load : the filter is applied inside the kernel and Scapy will only see ARP traffic. That means that you can use directly python language (assign variables, use loops, define functions, etc. The packets can be filtered by port. Each of these steps can be done in a different way dependent on your platform and on the version of Scapy you want to use. Basically Wireshark and Scapy sniffs 1 packet in like 1-3 minutes, and most of times it is an ARP packet. Ultimate goal is to detect access points nearby via Scapy ( not by sniffing beacon frames) The object of this is to learn how to initiate probe requests and collect the responses. It is the protocol that associates MAC addresses with IP addresses. But inside routep, I modify the src and dst mac address and try to send the received packet to appropriate host, scapy gives a warning:. The count parameter tells scapy how many packets to sniff. The iface parameter tells the sniffer which network interface to sniff on; if left blank, Scapy will sniff on all interfaces.
