Introduction

This article describes a very bare bones bootp daemon/server.
I needed a very simple bootp daemon for my current project but I could not find one on codeproject so I programmed one.
For more information about the bootp protocol see the wikipedia site about it.

Using the code

This bootp daemon only implements a subset of the bootp RFC-951 but it is enough to work for simple devices like the one I use in my project. The server can only handle one mac and ip address pair, but it is easy to expand the code to handle more pairs.

#include "bootpd.h"


void main(void)
{

    // Create the bootpd object

    Bootpd bootpd;

    // Set the broadcast address

    // You can use a mask to limit the broadcast scale

    // example '10.0.255.255'. In theory 255.255.255.255 means broadcast

    // to everyone in the world, but in practice filter routers these

    // messages.

    bootpd.m_broadcastIp    = "255.255.255.255";
    
    // Set the server address

    // Use 0.0.0.0 to listen to all network messages from anyone connected

    // to the network.

    bootpd.m_interfaceIp    = "0.0.0.0";
    
    // The ip address the bootp device should get.

    bootpd.m_targetIp        = "10.0.1.55";
    
    // The mac address of the device. Case insensitive.

    bootpd.m_targetMac        = "00:11:22:33:aa:bb";

    // Now start the server and listen to requests. 

    bootpd.Start();
}    

Bootp is a connection less protocol. This code will show you how to create a listening socket to listen to broadcast messages and how to send a broadcast message.
