采用OpenBSD 4.3自带的DHCP

1. /etc/dhcpd.conf

# cat /etc/dhcpd.conf

default-lease-time 36000;

max-lease-time 72000;

option domain-name-servers 59.108.38.195;

#ddns-update-style ad-hoc;

#log-facility local7;

# for admin vr1

shared-network Admin-NET {

optiondomain-name "atyu30.com";

subnet 192.168.1.0 netmask 255.255.255.0 {

option broadcast-address 192.168.1.255;

option routers 192.168.1.1;

range 192.168.1.10 192.168.1.200;

}

}

# for office vr2

shared-network Office-NET {

subnet 192.168.2.0 netmask 255.255.255.0 {

option broadcast-address 192.168.2.255;

option routers 192.168.2.1;

range 192.168.2.50 192.168.2.150;

}

}

# for Server vr3

shared-network Server-NET {

subnet 172.16.71.0 netmask 255.255.255.0 {

option broadcast-address 172.16.71.255;

option routers 172.16.71.1;

range 172.16.71.50 172.16.71.150;

}

}

host Gate-OpenBSD {

next-server 192.168.1.100;

hardware ethernet 00:0E:7B:37:96:6C;

fixed-address 192.168.1.120;

}

}

2.启动

# touch /var/db/dhcpd.leases

# dhcpd vr1 vr2 vr3

3./etc/rc.conf.local

dhcpd_flags="" # for normal use: ""

4./etc/dhcpd.interfaces

#dhcpd的****端口：

# cat /etc/dhcpd.interfaces
