[solved] Can dhcpd.conf 'filename' point to a http server?

If you're booting all your machines with iPXE burned into the ROM of the network adapters or always boot iPXE from USB or CD you can just use http:// URLs directly in your DHCP configuration (or you can use an embedded script to skip filename configuration from DHCP at all), because iPXE understands HTTP natively. But that is not the setup most people have, which is why the chainloading feature exists.

It enables you to load iPXE just once from TFTP and then do the rest through HTTP (or some other method). If you want to have chainloading from traditional PXE firmware work you definitely need to have a TFTP server running. But it only needs to contain one file, namely undionly.kpxe (or ipxe.pxe if you prefer to use native iPXE drivers for all your hardware).
