Antw: Re: PXE only Config [OT]

[Leonhard Kurz]

Hi,

that's basically the way it works. The pxe client requests all its "normal stuff" and after that, it requests basically two other options: "filename" and "next-server". The protocol was invented by Intel and you can find a pretty good document describing it there (http://download.intel.com/design/archives/wfm/downloads/pxespec.pdf).  In there a "dhcp proxy" is described, and that's exactly what we're looking for. There are many reasons why you can't or don't want to integrate into existing dhcp services. Me e.g., I'm a consultant and I'm going onsite to customers installing servers in a scripted way and I'd like to use pxe. I don't want the customer to change his dhcp settings just for the short time I'm onsite. Often thy are not willing to do so or the dhcp service is run by a different team and it's far too much effort to convince them to change their system.

I don't have a lot of experience in bureaucratic big shops, so it's
been difficult to concieve of a situation where DHCP needed to be
deployed seperately from PXE and what that would look like.  

It was my understanding that the dhcp client would request a lease,
then the address and all other pertinent information would be sent to
the client.  I did not realize that the client asked for PXE
information seperately.  

If somebody spent a few scarce seconds setting me straight, I would
certainly appreciate it.
