[Dnsmasq-discuss] Dnsmasq-2.77 pxelinux.0 question

[Steven Shiau]

Hi Simon,

I have a question about using dnsmasq 2.77 as the PXE booting service.
This is running on Debian Sid amd64 version, the package is from Debian
repository:

root at debian:~# dpkg -l dnsmasq
Desired=Unknown/Install/Remove/Purge/Hold
|
Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name                   Version          Architecture     Description
+++-======================-================-================-=================================================
ii  dnsmasq                2.77-1           all              Small
caching DNS proxy and DHCP/TFTP server

root at debian:~# dpkg -l dnsmasq-base
Desired=Unknown/Install/Remove/Purge/Hold
|
Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name                   Version          Architecture     Description
+++-======================-================-================-=================================================
ii  dnsmasq-base           2.77-1           amd64            Small
caching DNS proxy and DHCP/TFTP server

I have configured dnsmasq.conf as:
root at debian:~# cat /etc/dnsmasq.conf
log-dhcp
dhcp-no-override
enable-tftp
tftp-root=/tftpboot/nbi_img
dhcp-range=192.168.120.3,proxy

## PXEClient:Arch:00000
pxe-service=X86PC, "Boot BIOS PXE", pxelinux.0

## PXEClient:Arch:00007
pxe-service=BC_EFI, "Boot UEFI BC", bootx64.efi

## PXEClient:Arch:00009
pxe-service=X86-64_EFI, "Boot UEFI X86-64", bootx64.efi

pxe-prompt="Booting PXE Client", 1

However, when I boot the PXE client, it fails and the error messages is
"PXE-T01: file /tftpboot/nbi_img/pxelinux/pxelinux.0.0" not found"
as attached.

I remember in dnsmasq <= 2.75, it used to append ".0" to the PXE
basename file. However, for dnsmasq 2.76, the PXE basename is not
appended with ".0" if I use basename as "pxelinux.0".

I did not see any related description about this change in the changelog
for dnsmasq-2.77:
http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2017q2/011542.html

Is this just a regression, or is it meant to revert to the old way? Or
where am I wrong?
Thank you very much.

Steven
