4 # This is a virtual server that handles DHCP.
8 # This code is experimental, and SHOULD NOT be used in a
9 # production system. It is intended for validation and
10 # experimentation ONLY.
12 # In order for this to work, you will need to run configure:
14 # $ ./configure --with-dhcp
16 # $ vi share/dictionary
18 # ## Un-comment the line containing $INCLUDE dictionary.dhcp
19 # ## Then, save the file.
23 # DHCP is NOT enabled by default.
25 # The goal of this effort is to get the code in front of
26 # people who are interested in another DHCP server.
27 # We NEED FEEDBACK, patches, bug reports, etc. Especially patches!
29 # Please contribute, or this work will be nothing more than
34 # A: It allows the server to receive DHCP packets, and to
35 # respond with static, pre-configured DHCP responses.
37 # Q: Does it do static/dynamic IP assignment?
38 # A: No. Or, maybe. Try it and see.
40 # Q: Does it read ISC configuration or lease files?
41 # A: No. Please submit patches.
43 # Q: Does it have DHCP feature X?
44 # A: No. Please submit patches.
46 # Q: Does it support option 82?
49 # Q: Does it support other options?
50 # A: Maybe. See dictionary.dhcp. Please submit patches.
52 # Q: It doesn't seem to do much of anything!

60 # The DHCP functionality goes into a virtual server.
64 # Define a DHCP socket.
66 # The default port below is 6700, so you don't break your network.
67 # If you want it to do real DHCP, change this to 67, and good luck!
69 # You can also bind the DHCP socket to an interface.
70 # See below, and raddb/radiusd.conf for examples.
72 # This lets you run *one* DHCP server instance and have it listen on
73 # multiple interfaces, each with a separate policy.
75 # If you have multiple interfaces, it is a good idea to bind the
76 # listen section to an interface. You will also need one listen
77 # section per interface.
79 # FreeBSD does *not* support binding sockets to interfaces. Therefore,
80 # if you have multiple interfaces, broadcasts may go out of the wrong
81 # one, or even all interfaces. The solution is to use the "setfib" command.
82 # If you have a network "10.10.0/24" on LAN1, you will need to do:
84 # Pick any IP on the 10.10.0/24 network
85 # $ setfib 1 route add default 10.10.0.1
87 # Edit /etc/rc.local, and add a line:
88 # setfib 1 /path/to/radiusd
90 # The kern must be built with the following options:
91 # options ROUTETABLES=2
92 # or any value larger than 2.
94 # The other only solution is to update FreeRADIUS to use BPF sockets.
102 # The DHCP server defaults to allowing broadcast packets.
103 # Set this to "no" only when the server receives *all* packets
104 # from a relay agent. i.e. when *no* clients are on the same
105 # LAN as the DHCP server.
107 # It's set to "no" here for testing.
110 # On Linux if you're running the server as non-root, you
113 # sudo setcap cap_net_admin=ei /path/to/radiusd
115 # This will allow the server to set ARP table entries
116 # for newly allocated IPs
119 # Packets received on the socket will be processed through one
120 # of the following sections, named after the DHCP packet type.
121 # See dictionary.dhcp for the packet types.
