ubuntu10.04 server版启动DHCP时一直fail,请高手指点。谢谢！

用apt-get install dhcp3-server 装完dhcp组件，默认会启动下服务，会显示fail
报错在syslog如下：

dhcp服务需要配置下,已经给你提示了

No subnet declaration for eth0 (10.20.48.116).

Not configured to listen on any interfaces!

配置贴出来看下

miaolinux

配置如下
log-facility local7;

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.50 192.168.1.70;
option domain-name-servers 202.103.0.117,202.103.24.68,202.103.150.44;
option domain-name "apt-get.cn";
option routers 192.168.1.1;
option broadcast-address 192.168.1.255;

修改配置文件,把subnet 192.168.1.0 netmask 255.255.255.0修改成subnet 10.20.48.0 netmask 255.255.255.0
然后把后面{}里面的192段修改成10.20.48.0段的ip,重启dhcp服务

    非常感谢您的热心回复。我自己刚才也发现问题出在这里了。确实是这样。因为之前是单机测试的，后来联网下组件，改了IP。DHCP里的IP段没有改，导致这个问题。
