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 {
    option  domain-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;
