iPXE discussion forum

Hello,

This is what I have and compil from rom-o-matic and work:

But I want to passing variable in this menu something like:


I see the complet menu of robinsmidsrod, and I tried:

And in boot.ipxe.cfg:

It's not working. Only when I compil this full IP.

I don't understand where is my error? Can you show me the way to work?
Thanks

variables are set by http://ipxe.org/cmd/set and are kept between scripts
--autofree and --replace are only about how the script file itself is handled.

if you have chain boot.ipxe.cfg in your embedded script, after dhcp, it would try to use the default tftp path.
If your http server is on the same server (ip) as your original tftp server than you could use something like:
chain http://${netX/next-server}/boot.ipxe.cfg

You might want to use the config command from the iPXE shell to see what is set

Hello,
Thanks for your answer.

I'm very very sorry, but I simply don't underdstand. Sorry...

Yes, my TFTP server is on the same IP.

I try this on rom-o-matic:

and in my boot.ipxe.cfg


And my root TFTP is:

When I boot, I have error No boot device, no such file or directory and It's loop reboot.

Thanks

I strongly suggest to use netX not net0

Could you please post the full error message that you are seeing? Including the ipxe.org url in the message?

Hello,
I tried with netX, nothing better. Sorry.

???

Thanks

try add some sleep and echo in your script to ensure it's actually running

I add:

sleep 5 between each step and add echo http://${netX/next-server}/boot.ipxe.cfg

Nothing sleep and nothing echo.

Sorry don't know...

Let's try with some debugging code inserted and also some troubleshooting options:


The above script should give you a pretty clear idea of what if going on without having to do too many gymnastics with the keyboard.

I suspect the issue is a missing URI descriptor (tftp:// http://)...

Let us know the output.

It's little bit better!
Something new!

With your script Mr MultimediaMan I have something like this:

My PXE server ip is 192.168.10.118

192.168.10.1 is my router.

I also tried with:

Same IP display.

Near of solution?
Thanks to help me! Very cool!
Hope to read yours answers

OK, I have an idea of the problem...



Please try that and post the output.

Best,

The same:

OK, this problem is easy to fix. But the real problem is your DHCP server configuration. If you have configured an iPXE class in the DHCP Server, please check your settings there.

Can you post up your /etc/dhcp/dhcp.conf for the Subnet for PXE/iPXE and any global settings?

The Issue Is DHCP Option 66 ${next-server} is set to 192.168.10.1 but it should be set to 192.168.10.118

There are a couple of different ways to address this...

1: Use DHCP Option 17 ${root-path} (Best way IMHO) instead of relying on DHCP option 66 ${next-server}. ${root-path} is a string variable and can be anything up to 255 characters.

2: Fix your DHCP Option 66/ iPXE class.

3: Ghetto method (not using any DHCP-passed variables, using values burned into iPXE):

I'm using DNSMASQ with proxy relay to my router.

This what I tried:

dnsmasq.conf


And new boot efi:

But no more.

echo ${root-path} show me 192.168.10.1

And echo ${root-path}/menu.ipxe show me /menu.ipxe ... no such file or directory

Thanks

OK, add these lines in your DNSMASQ:

Replace Line 14 with the following and restart DNSMASQ:


Here is your new embedded script:


Best,

M^3

Sorry, same result.
Error
echo ${3} show me 192.168.10.1
echo ${17} is empty

initrd http:///menu.ipxe

Failure! (ipxe.org/err/3e11618e)

And that what I tried now:

My snponly.efi built with:

because show 66 return me the right IP of my pxe-server.

And It's works.

echo ${3} show me 192.168.10.1
echo ${17} empty
echo ${66} show me 192.168.10.118

But I'm not feel good with this solution. But maybe you can explain me. This morning (for me) I don't know dhcp-option before you show me.
Why option 66 show me the right IP instead of 192.168.10.1 like in dnsmasq.conf?!
Does I need to change something to have a "right classical" configuration?

Thanks and sorry for distrub, I would like to have good config.

What you have will work.

DNSMASQ will assume to use the DNSMASQ Server IP for all standard DHCP options unless you tell it otherwise.

IMHO, you are good right now with what you have... there are "better" ways to do it (Using DNS names and more generic Variables), but you are on the right path for now at least.

Best,

M^3

Thanks,
I will continue and post when I have finish.

My final snponly.efi generate by rom-o-matic that work:

UEFI + dnsmasq


Hop can help.
Many thanks for your help!
