DHCP服务!哪位兄弟来帮帮我！
DHCP服务启动失败
看了北南兄写的“怎样设置DHCP［参考篇］”后自己用现有网络也配置了一下DHCP服务但吂后
失败。请Linuxsir的兄弟们帮帮我！！！
我的网络环境是：
主机：双网卡ADSL共享上网。Radhat9.0
外卡接ADSL：10.0.0.3 255.255.255.0
内卡DHCP服务：192.168.1.1 255.255.255.0
注：我没有用HUB 是双网卡叉接的。双网卡共享上网正常。客户机是WIN2K。我只想为192.168.1.0的网段提供服务。对了北南兄配置的DHCP服务中没有向客户机分配网关啊。请问 option broadcast-address 192.168.1.1; 这一句是不是就是向客户机分配网关？
根据北南兄的贴子。我的dhcpd.conf配置为：
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option nis-domain "domain.org";
option domain-name "domain.org";
option domain-name-servers 61.139.2.69;
option time-offset -18000;
range 192.168.1.2 192.168.1.255;
default-lease-time 21600;
max-lease-time 43200;
}
subnet 10.0.0.3 netmask 255.255.255.0 { }
启动DHCP后报错信息如下：

你把10.0.0.3那行注释掉。
还有启动dhcpd好像是用/etc/init.d/dhcpd start的，不过我用的是debian。

为什么不能删除自己的帖子？

是这个问题吧
subnet 10.0.0.3 netmask 255.255.255. 255 { }
由 tower 在 08-10-2003 21:14 发表:
刚才又仔细看了一下 dhcpd 的 man ，应该可以指定dhcp工作在指定网卡上 dhcpd ethx 就可以了；如果是rh,在/etc/sysconfig/dhcpd中加上 "DHCPDARGS=ethx"再 重起服务就可以了
由 yxheyong 在 08-12-2003 21:49 发表:
还是不行。
1-
wangguoqin1001兄说的/etc/init.d/dhcpd start启动也是启动的一种。我试过的不能正确启动。

tower兄说的。第一个问题和第二个问题我也设置过。设置后出现

we want the nameserver to appear at a fixed address

fixed-address 207.175.42.254;
#}
}
====================================================================
可以工作,我的也是两台机.我的DHCP服务器是副机上,让主机的内网卡,获取192.168.0.1.这样作没什么意义,仅为作作试验而已.

nobody_am兄
你 dhcpd.conf和我的没有什么区别啊。
我现在的dhcpd.conf是这样设置的。请大家在帮我看看。我自己觉得在dhcpd.conf文件的设置中应该没什么问题。但就是不能启用。
dhcpd.conf内容
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option nis-domain "domain.org";
option domain-name "domain.org";
option domain-name-servers 61.139.2.69;
option broadcast-address 192.168.1.255;
range dynamic-bootp 192.168.1.2 192.168.1.254;
option time-offset -18000;
default-lease-time 21600;
max-lease-time 43200;
}
subnet 10.0.0.3 netmask 255.255.255.255 { }
dhcpd start后报错内容：

本人E文不好。对于报错的信息不是懂。翻译了一下好象是说dhcp不能着用于eth1。在No subnet declaration for start (0.0.0.0).这一句中说是subnet的问题。还请大家帮我看看还有什么地方不对的。

把下面这行去掉试试，我觉得这行没有必要。
subnet 10.0.0.3 netmask 255.255.255.255 { }

由 yyja 在 08-13-2003 21:58 发表:
此问题是dhcpd服务不知道在那个介面侦听，与配置文件格式无关，但我不清楚如何在命令行设置dhcpd侦听介面

Glue兄：
不能正确启动的原因不是
subnet 10.0.0.3 netmask 255.255.255.255 { }
这句。我将它删除后也不能启动。
