iPXE Not Making Requests to Port 4011

Unfortunately I can't do that automatically unless I can get the darn thing to send a query to my proxy DHCP server, since changing the configuration of the DHCP server running on port 67 isn't practical in my situation. (In which case my problem would be solved, anyway, since the rest of the boot process works fine once I can get a filename to iPXE.)

So at this point it looks as if I'm stuck.

I did, however chainload the above link, which gave me a build from commit 4a4da (which is HEAD of the master branch from the Git repo) and examined its boot behaviour; it has the same problem as the 6366fa7a that came with QEMU: it never sends a request to port 4011.

I'm wondering, do I not properly understand the behaviour that's supposed to be happening here? Is a PXE client not supposed to be sending DHCP requests to port 4011 as well as port 63, by default?

Pressing ctrl-b so you can run the above commands is what you tested right? (note we are talking about tests to identify the issue, a fix will have to come after that)

I'm a bit fuzzy on ProxyDHCP ... maybe this post will be helpfull:
http://forum.ipxe.org/showthread.php?tid=6865 I'm thinking that proxyDHCP requests are only done when there next-server or filename is missing in the orignal reply, which it does seem to be in your case but might be worth double checking both the DHCP Offer and the DHCP Reply.
