Hello,
i'd like to boot a host from different ways using a database: ipxe, pxelinux,
local boot.. but i can't manage ipxe and pxelinux together.
In my dhcpd.conf file i have this:
if exists user-class and option user-class = "iPXE" {
filename =
concat("http://${next-server}/cm/engine/boot_ipxe.php?FILENAME=",binary-to-ascii(16,
8, ":", substring (hardware, 1, 6)));
} else if exists user-class and option user-class = "rawpxe" {
filename = "PXEClient/pxelinux.0";
} else {
filename "ipxe/undionly.kpxe";
}
So when an host is booting, i can load the boot_ipxe.php script. This script is
launching a shell script to determine what kind of boot the host has to do,
querying a database. So i've managed successfully booting from ipxe and from a
local disk but when i'm trying to boot from PXElinux it's not working.
In the documentation of the chain command(http://ipxe.org/cmd/chain) i have
found some explanation:
"If this command is executed from within an iPXE script, then the URI will be
interpreted as being relative to the URI of the script itself. For example, if
the script http://boot.ipxe.org/demo/boot.php contains the line
chain pxelinux.0
then iPXE will download and boot http://boot.ipxe.org/demo/pxelinux.0.";
I have successfully load the pxelinux.0 file but when PXE starts i can read
this:
TFTP prefix: http://${next-server}/cm/engine/boot_ipxe.php?FILENAME=xxxxx
That's why i can't boot from a classical PXE process... so this is my question,
is there a way to change the TFTP prefix using iPXE? Even when i used the
command "chain tftp://.../pxelinux.0";, the TFTP prefix refers to the original
script path.
In my PHP script i have something like this:
echo "#!ipxe\n";
echo "set user-class rawpxe\n";
echo "chain tftp://\${next-server}/PXEClient/pxelinux.0\n";;
Any ideas? AM i missing something?
Thank you for your help, if it's unclear, don't hesitate to contact me.
Best regards,
Yann.
