XUbuntu 8.04 i386。装了dhcp3-server。
使用 sudo /etc/init.d/dhcp3-server start 出错：

系统的 eth0  连接内网
inet 地址:192.168.0.1  广播:192.168.0.255  掩码:255.255.255.0
系统的 eth1 连接外网

/etc/dhcpd.conf 内容为

option subnet-mask 255.255.255.000;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;

subnet 192.168.0.0 netmask 255.255.255.0 {

option routers 192.168.0.1;
option broadcast-address 192.168.0.255;
