Issue with iPXE and PHP

[sarahphillips]

Hi! I was wondering if someone could give me a sanity check please because something is going wrong with my attempt to implement a PHP bootserver...

Essentially the problem is that iPXE gets the first script but hangs after getting the second (with no error).

I have DHCP, TFTP and Apache set up correctly. I am able to build iPXE with the embedded demo script from the documentation. That works fine (loads the kernel from http://demo.ipxe.org etc).

So what I am trying to do is to have an embedded ipxe script that points to my local webserver: http://bs1/boot.php?mac=zzzzzzzzzzzz etc. This is the script I embedded:


#!ipxe

dhcp
chain http://bs1/boot.php?mac=${net0/mac}


(FYI, I tried it with the FQDN and iPXE kept giving me dns error, so I just put http://bs1 now...).


The reason I am passing the mac address is that I intend to serve different images according to the machines mac address (guess thats obvious!).

The PHP script I have on my webserver is:


<?PHP
header ("Content-type: text/plain");
$ma = $_GET['mac'];

echo "#!ipxe\n";
echo "dhcp\n";
echo "chain http://boot.ipxe.org/demo/boot.php";

?>


As you can see, I have pointed this script to your demo site as a test and last-resort because I tried pointing it to local kernel and initrd and it hung then too. So iPXE wont access mine or your files, but simply hangs and shows no error. Help!!
Am I missing something obvious?

I wondered if it was due to formatting of the php or something...
