What you'll learn
what is TCP/IP model
Different parts of a packet of data
Ethernet header in detail
IP header and how IP protocol works in detail
TCP vs UDP
UDP header
TCP header , concepts and mechanisms
sockets and port numbers
how we could send data using sockets in python
creating a client-based communication in python using sockets
sockets vs raw sockets in python
struct module in python
converting decimal , hexadecimal and binary to each other using python built-in functions like hex(), int(), bin()
binascii standard module in python
ord() and chr() built-in functions in python
different fields of an arp packet in detail
how to have complete access over our packet using raw sockets in python
creating and injecting arp packets using raw sockets in python



Requirements
knowing the basics of python
knowing some networking basic concepts will help you to understand this better , even though we will almost cover it
a laptop with internet with any operating system
having kali linux installed virtually on your system or another system

Description
in this course first the TCP/IP model has been discussed and then main protocols in different layers are explained in detail so that you could understand them better when we enter python world. then using the knowledge from last lectures we start creating packets using a high level and then at the lowest level possible in python which is python raw sockets. after we inject and send and receive them on different system we analyze all packets in the communication by wireshark.
Who this course is for:
everyone who wants to know the core concepts of TCP/IP networks and also to use python for network programming
