Hello,
Sorry if what I'm about to ask is impossible, but I just really needed
to know one way or another.
I find dnsmasq such a handy utility for all kinds of situations (so huge
thanks for creating it!)... one such situation was back when I was
working with ThinStation and I'd do something like this to quickly test
how a new build would boot on some PXE enabled machines...
dnsmasq -d -i enp2s0 -F192.168.1.0,proxy --enable-tftp
--tftp-root="$(pwd)/build/boot-images/pxe" -p0 --log-dhcp
--pxe-service=x86PC,'Network Boot',boot/lpxelinux/lpxelinux
Ultimately it's the "proxy-DHCP" that I'm focussing on here.
Would it be possible to use this technique to add extra arbitrary DHCP
options to a reply instead? without touching the config of the
authoritative "other" DHCP server? e.g...
dnsmasq -d -i enp2s0 -F192.168.1.0,proxy --enable-tftp
--tftp-root="$(pwd)" -p0 --log-dhcp -O 160,tftp://192.168.1.2
This would be really handy in a scenario where you need to tell a bunch
of devices (e.g. Polycom phones) a new provisioning URL (in that example
option 160) on a temporary basis whilst you reboot/factory-reset them.
Especially when you're stuck using whatever existing DHCP server is on
the network with no ability (or great difficulty) to reconfigure it.
But I have a feeling I'm going to be told that "proxy-DHCP" is, and can
only be, a PXE specific thing? if so, what is that?
Thanks
