CMSIS network library

There are lots of documentation about the DHCP protocol on the net. And there is also a number of DHCP servers available with reasonably licensed source code available.

So the information needed to implement a DHCP server is available - the challenge is to decide what functionality the server needs to implement and what simplifications that can be acceptable. For example do you support just a single PC or can the user make use of a switch and expect to get IP numbers to 100 different units.

Hi Per Westermark,

The functionality of the server needs to assign a IP address to the client which is given by me, for a period of 1 day and i would like to support only one PC.

Can you share the information about this. It would be a great help.

can i know the steps involved from the scratch to develop or if you can share your implement on this.

Here's something i knocked up a few years ago as a simple test:

#!/usr/bin/env python

import socket,traceback

host = '192.168.1.111'
port = 67

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
s.bind((host, port))

while 1:
        try:
            message, address = s.recvfrom(8192)
            print("DHCP Request detected")
        except (KeyboardInterrupt, SystemExit):
            raise

With a little work, this could become a useful DHCP server. I'll let you figure out how.

"Can you share the information about this. It would be a great help."

Maybe surprise us and spend a bit of own time on the project? I would not earn any money from spending time supplying you with a DHCP server.

If this is a school project, then you are expected to learn.

If this is a hobby project, then the primary reasons would be because you are interested and want to learn.

If this is a commercial project, they you get paid to do this work.
