#

#	This is a virtual server that handles DHCP.

#

#		!!!! WARNING !!!!

#

#	This code is experimental, and SHOULD NOT be used in a

#	production system.  It is intended for validation and

#	experimentation ONLY.

#

#	In order for this to work, you will need to run configure:

#

#		$ ./configure --with-dhcp

#		$ make

#		$ vi share/dictionary

#

#	## Un-comment the line containing $INCLUDE dictionary.dhcp

#	## Then, save the file.

#

#		$ make install

#

#	DHCP is NOT enabled by default.

#

#	The goal of this effort is to get the code in front of

#	people who are interested in another DHCP server.

#	We NEED FEEDBACK, patches, bug reports, etc.  Especially patches!

#

#	Please contribute, or this work will be nothing more than

#	a curiosity.

#

#

#	Q: What does it do?

#	A: It allows the server to receive DHCP packets, and to

#	   respond with static, pre-configured DHCP responses.

#

#	Q: Does it do static/dynamic IP assignment?

#	A: No.  Or, maybe.  Try it and see.

#

#	Q: Does it read ISC configuration or lease files?

#	A: No.  Please submit patches.

#

#	Q: Does it have DHCP feature X?

#	A: No.  Please submit patches.

#

#	Q: Does it support option 82?

#	A: Yes.

#

#	Q: Does it support other options?

#	A: Maybe.  See dictionary.dhcp.  Please submit patches.

#

#	Q: It doesn't seem to do much of anything!

#	A: Exactly.

#  The DHCP functionality goes into a virtual server.

#

server dhcp {

#  Define a DHCP socket.

#

#  The default port below is 6700, so you don't break your network.

#  If you want it to do real DHCP, change this to 67, and good luck!

#

#  You can also bind the DHCP socket to an interface.

#  See below, and raddb/radiusd.conf for examples.

#

#  This lets you run *one* DHCP server instance and have it listen on

#  multiple interfaces, each with a separate policy.

#

#  If you have multiple interfaces, it is a good idea to bind the

#  listen section to an interface.  You will also need one listen

#  section per interface.

#

#  FreeBSD does *not* support binding sockets to interfaces.  Therefore,

#  if you have multiple interfaces, broadcasts may go out of the wrong

#  one, or even all interfaces.  The solution is to use the "setfib" command.

#  If you have a network "10.10.0/24" on LAN1, you will need to do:

#

#  Pick any IP on the 10.10.0/24 network

#	$ setfib 1 route add default 10.10.0.1

#

#  Edit /etc/rc.local, and add a line:

#	setfib 1 /path/to/radiusd

#

#  The kern must be built with the following options:

#	options    ROUTETABLES=2

#  or any value larger than 2.

#

# The other only solution is to update FreeRADIUS to use BPF sockets.

#

	ipaddr = 127.0.0.1

#	interface = lo0

	# The DHCP server defaults to allowing broadcast packets.

	# Set this to "no" only when the server receives *all* packets

	# from a relay agent.  i.e. when *no* clients are on the same

	# LAN as the DHCP server.

	#

	# It's set to "no" here for testing.

	broadcast = no

}

#  Packets received on the socket will be processed through one

#  of the following sections, named after the DHCP packet type.

#  This next section is a sample configuration for the "passwd"

#  module, that reads flat-text files.  It should go into

#  radiusd.conf, in the "modules" section.

#

#  The file is in the format <mac>,<ip>

#

#	00:01:02:03:04:05,192.168.1.100

#	01:01:02:03:04:05,192.168.1.101

#	02:01:02:03:04:05,192.168.1.102

#

#  This lets you perform simple static IP assignment.
