charrua-core is an
ISC-licensed DHCP library implementation in OCaml.

It provides basically two modules, a Dhcp_wire responsible for parsing and
constructing DHCP messages and a Dhcp_server module used for constructing DHCP
servers.

charrua-unix is a Unix DHCP
server based on charrua-core.

mirage
is a Mirage DHCP unikernel server based on charrua-core.

Features

• Dhcp_server supports a stripped down ISC dhcpd.conf, so you can probably just
  use your old dhcpd.conf, it also supports manual configuration building in
  ocaml.

• Logic/sequencing is agnostic of IO and platform, so it can run on Unix as a
  process, as a Mirage unikernel or anything else.

• Dhcp_wire provides marshalling and unmarshalling utilities for DHCP, it is the
  base for Dhcp_server.

• All DHCP options are supported at the time of this writing.

• Code is purely applicative.

• It's in ocaml, so it's pretty cool.

The name charrua is a reference to the, now extinct, semi-nomadic people of
southern South America.

This project became one of the Mirage Pioneer
projects.

The master branch depends on upcoming mirage 2.9 at this point, if you want to
use it, you'll have to add the mirage development branch to opam, it also
requires opam version >= 1.2.2.
