U want to create DHCP server on FreeBSD ( NetBSD etc )?
simple just install the DHCP server pkg 1st, either thru ports or pkg_add..
trunasuci# pkg_info | grep dhcp
isc-dhcp30-server-3.0.7_3 The ISC Dynamic Host Configuration Protocol server
after install, edit /etc/rc.conf and add:
dhcpd_enable="YES"
dhcpd_flags="-q"
dhcpd_conf="/usr/local/etc/dhcpd.conf"
dhcpd_ifaces="xl1"
dhcpd_withumask="022"
dhcpd_ifaces is your network card facing the network..
later edit dhcpd.conf and put something like this:
allow unknown-clients;
ddns-update-style ad-hoc;
subnet 10.0.0.0 netmask 255.255.255.0 {
range 10.0.0.100 10.0.0.150 ;
default-lease-time 86400 ;
max-lease-time 86400 ;
option subnet-mask 255.255.255.0 ;
option domain-name-servers 61.6.32.162, 192.228.128.15, 208.67.222.222, 208.67.220.220,
161.142.201.17, 202.188.1.23 ;
option routers 10.0.0.200;
}
subnet is your network subnet
default-lease-time and max-lease-time is your dhcp server ip leased given to client, in seconds, before it refresh/expired and ask for new ip..
option domain-name-servers is DNS servers of your ISP, and any other DNS servers such as OpenDNS etc..
option routers is default gateway for your client setting, in this case it's your network card facing the network ( anyway it can configured to other ip/gateway in the network, no problem )
SAVE!!!
time to start and check the dhcpd daemon...
