Here’s a central part of a DHCP-DISCOVER: dhcp_discover = ( The whole thing is administrated in Python. Combining the layers with”/”, the packet is easily generated, and you may ask Scapy to send and wait for an answer. a DHCP message you may set something in the DHCP options, something in the BOOTP part, something in UDP, IP and maybe even in the Ethernet layer. In these variables you only set what you want to differ from the default. The scapy concept is very easy to understand: You design a packet by creating a variable for each layer that you need. (For more Python programs – see Downloads Third Edition) The Scapy concept all lengths that a packet may have – including too short/long. It is very beneficial to run a for-loop with e.g. This is a Python module that allows you to generate all sorts of legal and illegal packets. ![]() In my IoT book I have described how I have had great benefit in using “Scapy”. In IoT, networks are always “connected” – or at least they can be.
