把tftp的根搬到/var/lib/tftpboot看看。

谢谢你的回复。
我把dhcpd.conf里filename选项内容改为"/var/lib/tftpboot/pxelinux.0"、/etc/xinetd.d/tftp中server_args改为 -u nobody /var/lib/tftpboot，然后重启了dhcpd与xinetd两个服务，去客户机重启尝试，结果与前面是一样的：在取pxelinux.cfg/default无果（没有任何找到或没找到的提示）之后出现找不到内核的提示，随后是
  1. boot:
复制代码
的提示符。

排错的时候要分开处理。
1.客户机能拿到正确的ip地址么 ?
2.tftp能正常工作么，如果能，下载个文件试试看.
3.客户机能引导么，如果能，不用kickstart 能安装么
4.试验kickstart 安装。

LZ贴出一大堆信息，能耐心看完的又有几个呢?

多谢指点！！！
1、客户机能取到正确的IP；
2、……不晓得如何验证TFTP，以前也没用过，能麻烦您推荐一个TFTP客户端程序以供验证么？
3和4就表看了，2过了才能到这两步吧。

谢谢！！！
