RedHat 5.2 dhcpd启动失败
RedHat 在启动dhcp时提示失败,请帮忙看看是什么问题???
dhcpd.conf文件如下:

Perl code

## DHCP Server Configuration file.#   see /usr/share/doc/dhcp*/dhcpd.conf.sample  #ddns-upate-style interim;ignore client-updates;allow booting;allow bootp;filename "linux-install/pxelinux.0";next-server 20.20.4.18;default-lease-time 1200;max-lease-time 9200;option subnet-mask 255.255.0.0;option broadcase-address 20.20.255.255;#option routers 20.20.0.1;option domain-name-servers 20.20.0.1;subnet 20.20.0.1 netmask 255.255.0.0 {    range 20.20.253.10 20.20.254.254;}

在终端执行:/usr/sbin/dhcpd显示如下:

Perl code

[解决办法]
那些出错的选项应该放在 subnet 中：

Perl code

subnet 192.168.1.0 netmask 255.255.255.0 {    option routers          192.168.1.254;    option subnet-mask      255.255.255.0;    option broadcast-address        192.168.1.255;    option domain-name-servers      192.168.1.3;    option domain-name          "www.cao.com";　#DNS名称#    option domain-name-servers  192.168.1.3;    option time-offset      -18000;     range dynamic-bootp 192.168.1.128 192.168.1.255;    default-lease-time 21600;    max-lease-time 43200;        host ns {        hardware ethernet 52:54:AB:34:5B:09;#运行DHCP的网络接口的MAC地址#        fixed-address 192.168.1.9;    }}
