DHCP core library - a DHCP server and wire frame encoder and decoder

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.

You can browse the API for charrua-core at http://mirage.github.io/charrua-core/api

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.
