fedora，dhcpd 无法启动

历史：我有一个微型闪亮的插件服务器，我想将其插入我的 ADSL 路由器（或无论你想叫它什么）的一端（eth0），另一端（eth1）我想为我的 LAN 运行一个 dhcp 服务器。目前，我被困在让 LAN 工作上。操作系统是 fedora 12。我像这样配置我的 /etc/dhcp/dhcpd.conf：

#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample
#   see 'man 5 dhcpd.conf'
#

option domain-name "unknown.org";
option domain-name-servers 192.168.44.1;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.44.255;

default-lease-time 86400;
max-lease-time 172800;

subnet 192.168.44.0 netmask 255.255.255.0
{
host fedorabigbox
{
        hardware ethernet 00:19:66:8E:61:74;
        fixed-address 192.168.44.21;
}

#host mobile
#{
#       hardware ethernet ***;
#       fixed-address 192.168.44.22;
#}

        range 192.168.44.100 192.168.44.110;
        option routers 192.168.44.1;
}

# this is just dummy, as read many howtos, some suggesting to add a subnet blah netmask blah for each interface
subnet 192.168.33.0 netmask 255.255.255.0
{
        range 192.168.33.100 192.168.33.110;
        option routers 192.168.33.1;
}

但尝试通过以下方式启动服务器时，服务器无法启动/etc/init.d/dhcpd start

总的来说，如果有人能向我详细解释网络的工作原理就好了，我对这个东西还很陌生。

更具体的问题：如何将子网指向 eth1 并将另一个子网指向 eth0，如何实现？

有人发现任何错误或缺陷吗？语法应该是正确的，已经用 dhcpd 语法检查检查过了。

谢谢你的帮助

我可以向您展示我的 Fedora“路由器”/防火墙的配置。我正在运行 Fedora 14（最近从 Fedora 13 升级）它有 2 个以太网卡（eth0 和 eth1）。eth0 是内部网络（10.0.0.x）eth1 是连接到我的有线电视运营商的外部网络。我的“路由器”有内部地址 10.0.0.3 我替换了名称并使一些信息通用。在需要的地方用您的特定信息替换。

option domain-name-servers 10.0.0.3, <external-dns1-ip>, <external-dns2-ip>;
# Sample /etc/dhcpd.conf
# (add your comments here) 

option domain-name "net.home";

group {
host pc1 {
    fixed-address 10.0.0.2;
    hardware ethernet xx:xx:xx:xx:xx:xx;
    }
host pc2 {
    fixed-address 10.0.0.4;
    hardware ethernet yy:yy:yy:yy:yy:yy;
    }
# Canon Pixma iP5200R
host printer1 {
    hardware ethernet zz:zz:zz:zz:zz:zz;
    fixed-address 10.0.0.12;
    }
# Wireless IP camera
host ipcamera {
    hardware ethernet ww:ww:ww:ww:ww:ww;
    fixed-address 10.0.0.15;
    }
}


 # home.net
 subnet 10.0.0.0 netmask 255.255.255.0 {
authoritative;
range 10.0.0.20 10.0.0.100;
default-lease-time 86400;
max-lease-time 86400;
option subnet-mask 255.255.255.0;
option broadcast-address 10.0.0.255;
option routers 10.0.0.3;
}
