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。

tower · 发表于 2003-8-10 17:28:05

是这个问题吧
subnet 10.0.0.3 netmask 255.255.255.255 { }

tower · 发表于 2003-8-10 21:14:47

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

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。
2-
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

下面是我的配置文件:
======================================================================
ddns-update-style interim;
ignore client-updates;

subnet 192.168.0.0 netmask 255.255.255.0 {

# --- default gateway

      option subnet-mask             255.255.255.0;

#    option nis-domain             "domain.org";
      option domain-name             "example.com";
      option domain-name-servers    192.168.0.2;

      range dynamic-bootp 192.168.0.1 192.168.0.2;
      default-lease-time 21600;
      max-lease-time 43200;

      # we want the nameserver to appear at a fixed address
      #host ns {

      #}
}
====================================================================
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.

yxheyong · 发表于 2003-8-13 20:51:21

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。

Glue · 发表于 2003-8-13 21:11:44

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 { }

yyja · 发表于 2003-8-13 21:58:04

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

yxheyong · 发表于 2003-8-13 22:27:35

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。
