#
#	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.

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 likely also need one
#  listen section per interface.

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