-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Does anyone know of a way (generic or vendor-specific) of including custom DHCP options to be sent from a PXE boot agent? I know the Intel specification allows for it, but I haven't seen any boot agents allow for it.
Specifically, I help support an open-source clustering project that can run either off separate media (either live CD/USB or direct-attach disk), or use a head node to serve up diskless clients. The head node supplies networking information to the other nodes using DHCP. When running off separate media, we can setup a separate logical network on a production network by using custom DHCP options, so that the DHCP server on the head node will only respond to DHCP packets specially tagged by a DHCP client. Both the ISC DHCP server and client make this pretty easy to setup. Unfortunately, all the PXE boot agents I've looked at don't support supplying custom options, which means we have to open up our DHCP server to accept packets from anyone. If there were a way to force the DHCP client in a boot agent to provide those options, then we could run in the same way in diskless mode as we do for separate media. Most of the people using this project that are interested in this project get a supported hardware kit from us to build a small cluster, so even if the solution is vendor-specific it wouldn't be a huge problem since we control what hardware we ship out. Currently, we use Realtek NICs and their boot agent.
