Scapy can be used to create and send custom packets, like a SYN packet, which is the first packet sent from a source host to a target host to initiate a connection.
Scapy allows for the assembly of specific packet layers, such as Ether, IP, and TCP layers, in a flexible manner.
When creating packets using Scapy, it is essential to include at least the IP layer (for destination IP address) and the TCP layer (for port number and flags) when communicating over TCP/IP.
Scapy can automatically populate default values for packet layers based on network setup, simplifying the process of packet creation.
To create a packet in Scapy, layers need to be properly ordered and assembled into a chunk before sending.
A SYN packet can be identified by setting the flag value to 'S' in the TCP layer, indicating that it is a SYN packet.
The process involves creating IP and TCP layers, assembling them into a packet, sending the packet, receiving a response, and dissecting the response to analyze the outcome.
Care should be taken to avoid flooding servers with SYN packets, as it can lead to consequences like being pursued by the server owners.- Explanation of packet details including IP layer, source Port, destination Port, and TCP layer
