Spelling: DHCP
Dynamic Host Configuration Protocol.
DHCP is an IETF [1] standard. It defines a protocol used by client
computers to obtain an IPAddress [2] and other configuration
information from a central server, rather than requiring the user to
configure it manually.
Most AccessPoint [3] hardware includes a DHCP server.
Grab a tarballed copy of the latest release from
ftp://ftp.isc.org/isc/dhcp/dhcp-latest.tar.gz
Alternatively you can install a package appropriate for whatever
[*NIX] distribution you have, such as dhcp-2.0pl5-8 for Redhat 7.2
Whatever you choose, you need a config file. A modified version of
the following will get you on your way (using an addressing structure
as described in RFC [4])
subnet 10.0.0.0 netmask 255.255.255.240 { option routers 10.0.0.1;
option subnet-mask 255.255.255.0; option domain-name
x.suburb.mlbwire.wan; option domain-name-servers 10.0.0.1; range
dynamic-bootp 10.0.0.2 10.0.0.14; default-lease-time 21600;
max-lease-time 43200; };
The 10.x.x.x addresses would be changed appropriate to the address
allocation for the node. This configuration results in address
allocation to local clients, but dhcp needs to be run with appropriate
options to ignore other interfaces that should not have automatically
configured addresses assigned.
The domain-name-servers line should specify a real domain name
server. More on that later.
