Scapy (https://scapy.net) is one of the powerful Python tools that is used to capture, sniff, analyze, and manipulate network packets. It can also build a packet structure of layered protocols and inject a wiuthib stream into the network. You can use it to build a wide number of protocols on top of each other and set the details of each field inside the protocol, or, better, let Scapy do its magic and choose the appropriate values so that each one can have a valid frame. Scapy will try to use the default values for packets if not overridden by users. The following values will be set automatically for each stream:
- The IP source is chosen according to the destination and routing table
- The checksum is automatically computed
- The source Mac is chosen according to the output interface
- The Ethernet type and IP protocol are determined by the upper layer
