几分钟后收到消息“DHCP 未收到报价！”。这是我在服务器上的 dhcp.conf

# Fixed IP addresses can also be specified for hosts. These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP. Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.

# You can declare a class of clients and then do address allocation
# based on that. The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all

# option routers rtr-29.example.org;

我应该改变什么才能让它发挥作用？
通过以太网连接的 PS 计算机
答案1
我见过的错误（我可能忽略了一些）：
- 以太网没有分配IP地址
- 您
dhcp.conf改用 wlan 接口上的地址范围 - 子网描述未在网络掩码中归零（子网应为 192.168.1.0带掩码 255.255.255.0)
- 分配的范围与 DHCP 服务器的 IP 地址重叠
- 我不确定 PXE 是否有必要，但
allow booting;线路allow bootp;不会dhcp.conf造成伤害。 - 除非您实际提供 DNS（您可能不提供），否则您的域名服务器选项将不起作用，但由于 PXE 不需要它，因此不会有什么坏处。
所以：
- 选择与您的 WLAN 不同的私有子网，例如
192.168.22.0。 - 让我们继续
192.168.22.30查看192.168.22.120分配的 DHCP 地址。 - DHCP服务器的地址必须是外部的，我们选择
192.168.22.1。 - 将此地址分配给
eno1withip addr add 192.168.22.1/24 dev eno1。 - 进行更改
dhcp.conf，重新启动dhcpd。
然后再试一次。
