  • Raw Socket program to implement Dynamic Host Control Protocol (DHCP)

How to run the socket

  • You need to give sudo permission for the scoket program to compile and run.
  1. sudo su
  2. gcc raw_socket.c
  3. ./a.out

Instruction to run the file

  • First get the interface by running ifconfig command in terminal
  • It will give ex: enp9s8
    1. sudo gcc dhcp.c -lpcap
    2. sudo ./a.out enp9s8

Output:

  1. enp9s8 MAC : 40:47:17:14:19:CA
  2. Sending DHCP_DISCOVERY
  3. dhcp.c:269:ether_output::Send 300 bytes
  5. Waiting for DHCP_OFFER
  6. dhcp.c:243:ether_input::Received a frame with length of [334]
