OpenBSD as DHCP Server

Task: OpenBSD server as DHCP server.
Description:OpenBSD server as DHCP server.
Howto: Ensure that DHCP Daemon is active: cat /etc/rc.conf.local should say (replace NIC name if different):
dhcpd_flags="fxp0"
Then, edit /etc/dhcpd.conf.
The options are pretty self-explanatory.
option domain-name "example.com";
option domain-name-servers 192.168.1.3, 192.168.1.5;
subnet 192.168.1.0 netmask 255.255.255.0
{ option routers 192.168.1.1;
range 192.168.1.32 192.168.1.127;
}
If you want to start dhcpd(8) from the command line, after editing /etc/dhcpd.conf, try:
touch /var/db/dhcpd.leases
dhcpd fxp0
The touch line is needed to create an empty dhcpd.leases file before dhcpd(8) can start.
