Hi,
I have a question regarding chain loading ipxelinux from within
pxelinux.
We are trying to integrate IPXE into our network boot environment due to
the benefit from faster data transmission rates with the featured http
functionality. So far our TFTP server hands out ipxelinux.0 with the
embedded pxelinux
to the clients upon boot and DHCP request. It is possible to load system
files over HTTP and even chain load to other pxelinux bootloaders with
the chainloader.com module.
Particularly what is not working is chain loading from ipxelinux to
ipxelinux; and chain loading from pxelinux to ipxelinux.
The machines just reboot without any further message.
The problem is that other departments point to our bootloader so we are
required to have a solution that takes a minimum amount of changes,
especially to the existing bootmenu entries from other departments. So
the basic idea was to simply replace pxelinux with ipxelinux on our
servers.
Any debugging tips or hints would be greatly appreciated!
pxelinux.0 is what version?
-hpa
I use version 4.0.6 from the same syslinux package as ipxelinux from
this source -> http://git.ipxe.org/people/mcb30/syslinux.git
I think the problem is with the pxechain module, it doesn't seem to work
with ipxelinux nor with gpxelinux...
But I found a workaround, it is possible to start ipxelinux.0 as a
kernel. In the ipxe script of ipxelinux I manually set the dhcp
next-server option to be the one of the server ipxelinux is loaded from,
thats what pxechain does normally.
e.g. If ipxelinux is on 10.4.9.1 the script would look like this:
#!ipxe
set use-cached 1
dhcp net0
set net0/dhcp.next-server 10.4.9.1
set net0/dhcp.filename ipxelinux.0
imgload pxelinux.0
boot pxelinux.0
this way it is possible to chain load from pxelinux to ipxelinux, from
ipxelinux to ipxelinux and with the pxechain module it is possible to
chain load from ipxelinux to pxelinux. That's all we need :)
Thanks everyone,
Michael
