[Dnsmasq-discuss] Feature request: make dnsmasq able to work as a proxydhcp

[Άλκης]

To boot from the network, a PXE client has to get some parameters like
the boot filename etc.
There are some environments (e.g. some school LTSP labs) where PXE
booting is desired, but a DHCP server is already running somewhere on
the network and it cannot be modified to also send the necessary boot
parameters.
In these cases, a PXE server (proxydhcp) would be really handy (defined
in paragraph 2.2.3 of
http://download.intel.com/design/archives/wfm/downloads/pxespec.pdf)

This PXE server would run on a different machine than the
existing/unmodifiable DHCP server, it would listen for DHCPREQUESTs in
port 69, and it would reply to the clients with extended DHCPOFFERs to
port 68. These extended offers would contain the necessary boot
information, but not ip/lease information.

AFAIK there aren't any open source proxydhcp implementations, so it
would be really helpful if dnsmasq had the ability to (also) act as a
proxydhcp (sending only extended but not normal dhcp offers).

Kind regards,
