Hi guys,
I'm using openwrt / lede devices for at least 5 years but never
actively submitted any line of code or something.
But i think the time has come ;)
I hope this is the right channel for this:
I added below lines to /etc/dnsmasq.conf:
# inspect the vendor class string and match the text to set the tag
dhcp-vendorclass=BIOS,PXEClient:Arch:00000
dhcp-vendorclass=UEFI32,PXEClient:Arch:00006
dhcp-vendorclass=UEFI,PXEClient:Arch:00007
dhcp-vendorclass=UEFI64,PXEClient:Arch:00009
# Set the boot file name based on the matching tag from the vendor
class (above)
dhcp-boot=net:UEFI32,i386-efi/ipxe.efi,tftpboot-server,192.168.30.254
dhcp-boot=net:UEFI,ipxe.efi,tftpboot-server,192.168.30.254
dhcp-boot=net:UEFI64,ipxe.efi,tftpboot-server,192.168.30.254
And the below lines to /etc/config/dhcp:
config boot linux
option filename 'pxelinux.0'
option serveraddress '192.168.30.254'
option servername 'tftpboot-server'
the auto generated config file /var/etc/dnsmasq.conf.cfg02411c
will only contain this line:
dhcp-boot=pxelinux.0,tftpboot-server,192.168.30.254
I'm a bit confused as i thought that the above dhcp-boot=net:UEFI*
lines should be available in the generated config which is indeed not
the case.
In /etc/init.d/dnsmasq I found in line 843:
append_parm "$cfg" "dhcp_boot" "--dhcp-boot"
as for example the pxe_service is scripted as a config_list_foreach:
config_list_foreach "$cfg" "pxe_service" append_pxe_service
below the version information and so on:
cat /etc/openwrt_releaseappend_parm "$cfg" "dhcp_boot" "--dhcp-boot"

for uefi I'm using this in dnsmasq.conf (maybe enable log to see more:
log-dhcp)
dhcp-match=set:X86PC,option:client-arch,0
dhcp-boot=tag:X86PC,undionly.kkpxe,,192.168.123.1
dhcp-boot=undionly.kkpxe
dhcp-match=set:BC_EFI,option:client-arch,7
dhcp-boot=tag:BC_EFI,bootx64.efi,,192.168.123.1
dhcp-match=set:efi-x86_64,option:client-arch,9
dhcp-boot=tag:efi-x86_64,ipxe.efi,,192.168.123.1
the /var/etc/dnsmasq file doesn't need to contain /etc/dnsmasq.conf
settings to work, they are included
so, enable the log to see more
in /etc/config/dhcp you only need the tftp root:
option enable_tftp '1'
option tftp_root '/mnt/sda3/tftpboot'
my ipxe is precompiled with the http path
