我通过查找 netboot 服务器设置找到了我的解决方案:
sudo apt install dnsmasq
touch /etc/dnsmasq.d/pxe.conf
我编辑了pxe.conf文件如下:
interface=enp5s0,lo
bind-interfaces
dhcp-range=enp7s4f0,192.168.2.2,192.168.2.10
dhcp-range=enp7s4f1,192.168.2.11,192.168.2.20
dhcp-range=enp8s6f0,192.168.2.21,192.168.2.30
dhcp-range=enp8s6f1,192.168.2.31,192.168.2.40
dhcp-boot=pxelinux.0
dhcp-match=set:efi-x86_64,option:client-arch,7
dhcp-boot=tag:efi-x86_64,bootx64.efi
enable-tftp
tftp-root=/srv/tftp
现在我的互联网连接在我的第二个以太网设备的每个接口上共享。
我对 dnsmasq 配置的最后更改也确实有效:
