简介:

我们可以通过调整启动文件来兼容不同的硬件(UEFI & BIOS),能否不手动调整呢?自动调整也是可以的。

本来是是想将DHCP放在H3C 5500上的,但是咨询过H3C的售前顾问后,没有任何一个型号支持这个功能,前面已经折腾过自动识别客户端类型,发送不同的启动文件了。为了更好的完成这个系列文章,以及添加shell脚本自动化处理,这篇还是写上吧。

双引导原理

我们知道两种系统启动文件不同,启动文件又是DHCP发送给终端的,那么需要DHCP识别客户端类型,RFC 4578规定了Option 93 是客户端类型的识别代码。我们就是通过DHCP识别终端的DHCP 发现数据包中的option93,从而发送给客户不同的启动文件。

RFC 4578: Dynamic Host Configuration Protocol (DHCP) Options for the Intel Preboot eXecution Environment (PXE) (rfc-editor.org)

抓包分析

过滤一下dhcp,可以看到discover包,包含93选项。

下图是抓的PXE bios

 再抓个 PXE-UEFI的

 看到有0有7。

openwrt dnsmasq 脚本设置

注意修改tfpt_root TFTP主目录

filename,启动文件名。

#!/bin/bash
uci set dhcp.@dnsmasq[0].logdhcp='1'
