Add multiple dhcp_match and dhcp_boot combinations

At home, I’m using netboox.xyz to make it possible for a client on the network to PXE boot and get a handy menu for choosing what Distro to run live or install on it through the network.

Currently, I have configured this though the Luci interface like so:

  1. Network / DHCP and DNS > TFPT Settings
  2. Network boot image: netboot.xyz.efi
  3. Network / Interfaces / LAN / DHCP Server / Advanced Settings
  4. DHCP-Options: 66,192.168.50.1

This works perfectly for all modern systems configured to use EFI when booting, however I’ve had some older machines using the classic BIOS unable to do the same because the image served through TFTP is, of course, as the name implies, meant to work with EFI.

Recently I stumbled on a page describing how you can serve a different filename depending on some meta-data sent through a DHCP/PXE boot request to the router.

Here’s the snippet:

dhcp-match=set:bios,60,PXEClient:Arch:00000
dhcp-boot=tag:bios,netboot.xyz.kpxe,,YOURSERVERIP
dhcp-match=set:efi32,60,PXEClient:Arch:00002
dhcp-boot=tag:efi32,netboot.xyz.efi,,YOURSERVERIP
dhcp-match=set:efi32-1,60,PXEClient:Arch:00006
dhcp-boot=tag:efi32-1,netboot.xyz.efi,,YOURSERVERIP
dhcp-match=set:efi64,60,PXEClient:Arch:00007
dhcp-boot=tag:efi64,netboot.xyz.efi,,YOURSERVERIP
dhcp-match=set:efi64-1,60,PXEClient:Arch:00008
dhcp-boot=tag:efi64-1,netboot.xyz.efi,,YOURSERVERIP
dhcp-match=set:efi64-2,60,PXEClient:Arch:00009
dhcp-boot=tag:efi64-2,netboot.xyz.efi,,YOURSERVERIP

I tried applying those through uci:

uci set dhcp.@dnsmasq[0].dhcp_match=set:bios,60,PXEClient:Arch:00000
uci set dhcp.@dnsmasq[0].dhcp_boot=tag:bios,netboot.xyz.kpxe,,YOURSERVERIP
uci set dhcp.@dnsmasq[0].dhcp_match=set:efi32,60,PXEClient:Arch:00002
uci set dhcp.@dnsmasq[0].dhcp_boot=tag:efi32,netboot.xyz.efi,,YOURSERVERIP
uci set dhcp.@dnsmasq[0].dhcp_match=set:efi32-1,60,PXEClient:Arch:00006
uci set dhcp.@dnsmasq[0].dhcp_boot=tag:efi32-1,netboot.xyz.efi,,YOURSERVERIP
uci set dhcp.@dnsmasq[0].dhcp_match=set:efi64,60,PXEClient:Arch:00007
uci set dhcp.@dnsmasq[0].dhcp_boot=tag:efi64,netboot.xyz.efi,,YOURSERVERIP
uci set dhcp.@dnsmasq[0].dhcp_match=set:efi64-1,60,PXEClient:Arch:00008
uci set dhcp.@dnsmasq[0].dhcp_boot=tag:efi64-1,netboot.xyz.efi,,YOURSERVERIP
uci set dhcp.@dnsmasq[0].dhcp_match=set:efi64-2,60,PXEClient:Arch:00009
uci set dhcp.@dnsmasq[0].dhcp_boot=tag:efi64-2,netboot.xyz.efi,,YOURSERVERIP
uci commit
/etc/init.d/dnsmasq restart

But it seems like for some reason only one entry is allowed.

Does anyone know how this could be configured correctly?

Per my little knowledge you would add several entries so first is [0], then next is [1]…

There’s a special notation just as you add a new entry, you can setup last entry without knowing the number by adding [-1]
