关于fedora无盘引导不能成功，求助～～～

denry39

主机：fedora 14 ,ip=192.168.100.100
从机为无盘站，现从机想从主机上引导，在主机网口中抓包如下：

在主机中没有找到有bootps这个服务，端口67也没打开，在网上查了下，fedora中好像没有bootps这个服务了？？？
请各位大人帮看看呀。。。。。

主机的dhcp服务安装正常吗?

denry39

楼上大哥正解，谢谢！原因在是dhcpd在安装时与dhclient发生冲突，未正确安装。
现有一新问题：
  在开启dhcpd之前需要设置监视网口的ip地址,   #ifconfig eth1 192.168.1.1
# service dhcpd start
在开启dhcpd之后，eth1的ip地址也没有了，监视网口的ip地址也成为动态的了？还请大侠们指点迷津。。。。。

你将网卡的ip地址设置成静态的ip,这样起到dhcp服务,也不会影响到你的网卡的ip.

如楼上大哥所言，eth1设置为静态IP

客户机启动到：

就挂了，貌似从主机log看，在向从机分配IP地址后，eth1就down下了，客户机得到的serve ip就成为0.0.0.0了,还请各位大哥们支招呀。。。。

检查下你dhcp服务的配置,cu有pxe安装系统的文档,你对照下看看你的配置是否正确
