booting a Raspberry Pi.
So, "pxe-service" lines that are NOT matched, cause the problem,
yet if they're commented out, the problem is gone...
Would that be an issue with dnsmasq, or with the UEFI PXE stack?

It would be simpler if we could do:
interface-name=webserver,*
Nevertheless, it saves us from modifying the dnsmasq configuration every
time the IP changes, so it's much better than what we had!
Thank you very much Simon!

p-hosts to static dns. Would it help if those hosts were assigned
infinite TTL to add permanent hostnames for them, similar to addn-hosts
record? I guess it would not hurt having permanent names on permanent
leases.

I.e. if pxe-service is not matched due to tags, to behave in the same

Shrenik, I wonder, if you use iptables or a firewall to completely
ignore packets to 4011, does the NUC client work then even if
pxe-service lines exist?
(I may be complete off-base there, it's just an idea...)

Hi Olaf,
yeah I too settled for a sed command that transforms a dhcp-hosts file
into an addn-hosts file.
I maintain the main information in the dhcp-hosts file and then I run
the sed command.

@Petr, thank you very much for troubleshooting this!
@Shrenik, are any changes required in ltsp-dnsmasq.conf?
Or we just need to apply Petr's patch, compile/install, and it works?

Normally, when one uses dnsmasq for DHCP and DNS, if a client includes a
hostname in the DHCP request, dnsmasq creates a DNS record for that.
We're using dnsmasq in proxyDHCP mode, and for DNS. We're using cheap
routers as DHCP servers.
What can we do to force dnsmasq to react when a client reques

Yes, I didn't see

Hi Simon, here's my minimal.conf with which I can reproduce the problem:

I just tried with git head, with the same results.
Another debugging hint... I tried commenting out the following line:
#dhcp-range=tag:efi,192.168.68.20,192.168.68.250,8h
Meaning that I only had the proxyDHCP range in effect:
dhcp-range=tag:!efi,10.161.254.0,proxy

OK, I managed to pinpoint the difference using another tcpdump command

$ sudo tcpdump -i eth1 port 67 or port 68 or port 69 or port 4011 -e -n

So I'm guessing that the problem is that with the latest patch, the

I forgot to mention that I also use the "no-ping" option in the second
dnsmasq instance, to avoid delays, since the client won't use the
DHCPOFFER IP anyway.
