-Allows hosts on your network
to be automatically told
the details of your
network. This is a good thing because it means that
you can easily renumber
your network without
having to go to every machine and
change it's
static ip
. You can still give machines static ip'
s with DHCP you simply bind the ip to the
[MACAddress
] of that machine. DHCP can also be used
to tell hosts about their gateway and their dns servers
.
+It allows machines
to configure their own network settings by querying a server about
the details of the
network. Thus,
you can make global configuration changes like renumbering
your network in a central place, rather than
having to change the
static [IP] of every single host separately
. You can still give machines static [IP]
s with [
DHCP] by binding
[IP
]s
to [MAC] addresses
.

-Under
[Debian
] [Woody
], you install "dhcp-client" for clients,
and "dhcp" for the
server. If you have interfaces other than eth0 and lo0 (such as wan0
for MetaNet), then by default dhcp will refuse
to start. You need to edit /etc/default/dhcp and put __INTERFACES="eth0"__. Unfortunately this isn't documented anywhere sensible like the dhcpd man page or the README.Debian file
.
+[DHCP
] is not restricted to giving machines
[IP
]s. In fact
, it can be used to configure a huge number of network related settings. Two such settings commonly configured via [DHCP] are the gateway
and [DNS]
server addresses
for clients
to use
.
-In /etc/dhcpd.conf, the options that take time values are in seconds, although the example file doesn't mention this. It's in the man page though, dhcpd.conf(5)
