Linux Internals Projects for Beginners | Network Packet Generator Project

One of the key requirements of network is the ability to handle a large volume of data. Network should have necessary resilience to handle, which is simulated using Network packet injectors in test environment. These packet injectors create a large volume of a particular network protocol traffic and help application developers to do load testing. 

The goal of this project is to create a command line based Network packet injector that will generate all major protocol packets (ex: HTTP). For implementation RAW sockets are used.

Here is the list of requirements that need to be implemented in this project. 

• • The packet generator should provide a prompt to the user upon invocation “PG>”
  • It should provide a “help” menu that would display various packets & options supported
  • Options to be supported as follows. The user can give one or all options
  • Appropriate error handling needs to be done
  • Option details:
    • generate_tcp
    • generate_udp
    • generate_ip
    • generate_icmp
  • After packet generation it should be verified using network packet analyzer tool like Wireshark

The skeleton code in a very interesting concept used in Emertxe. By looking into the skeleton code, you will get a clear picture into converting the given requirement into a working solution. This will also take care of important aspects like modularity, clean coding practices, re-usability etc.

Here are the sample output expected by the end of project execution.
