iPXE initialises devices ok but reboots when Configuring(net0 00:23:7d:b8:a5:54)......

luislesi · Jul 15, 2016, 4:12 PM

Hi,
I’m trying to configure fog in my school. My fog server is 10.1.8.1
The school has a dhcp server cisco with ip 10.1.8.254 that we do not control. It´s controlled by an external company of the government. We ask them to configure the dhcp server with bootfile undionly.kpxe and next server 10.1.8.1.
When client starts the iPXE initialises devices correctly but the computer reboots after Configuring(net0 00:23:7d:b8:a5:54)…

Can anyone help me?
Best regards,

Ask them to change the boot file to undionly.kkpxe (note the extra ‘k’). You will have better luck with this boot ROM generally.

First welcome to the FOG forums.

What target system are you trying to pxe boot? (mfg and model)
Is the target computer in bios (legacy) or uefi mode? (a different boot file is needed for each type)
What version of FOG are you running? (hint: look at the number near the cloud on the FOG management gui page)

@george1421

Thanks for the reply.
The computers are HP DC 7800. Bios is in legacy mode. The fog version is 1.2.0.
First i configured fog in a separated network and fog worked just fine with dhcp service. But in this network i have to use an existing dhcp server.

@Wayne-Workman
Thanks i will try that.

Wayne Workman · Jul 15, 2016, 5:42 PM

@luislesi There’s also the option to tell those guys to just remove the next-server and filename and try to use dnsmasq in ProxyDHCP mode. This way, you’re always in control of those extra options and not them.

I agree, when you have no control over the dhcp services then dhcpProxy running on a fog server is the next best thing (especially if you start having a mix of bios and uefi systems in your environment.

@Wayne-Workman

I changed the boot file to undionly.kkpxe and now it works but i have write exit in IPXE.
Do you know you to work around this?

Wayne Workman · Jul 18, 2016, 1:20 PM

@luislesi It’s like iPXE isn’t getting any arguments, to me. I’ve not seen this one before, I’m going to need to defer to the other @Developers and @Moderators.

Tom Elliott · Jul 18, 2016, 7:24 AM

@Wayne-Workman This isn’t something We’re doing. Maybe we can do more with the boot.php script output.

luislesi · Jul 18, 2016, 2:17 PM

@Tom-Elliott

I Tom. I had to change the boot file again to undionly.kpxe.
At this time i don’t know how i solved this problem.
I tried two things:
I updated the kernel to version 3.19.3 and I changed permissions of ipxe:

         chmod -R 775 /var/www/html/fog/service/ipxe

The only problem is that i have write exit in ipxe to download/upload start.

Many Thanks

@luislesi We need the output of the link that Tom requested.

luislesi · Jul 19, 2016, 3:22 PM

@Wayne-Workman

Today I installed another server with the same configurations and i noticed that the original problem was solved by getting another undionly.kpxe.

wget https://svn.code.sf.net/p/freeghost/code/trunk/packages/tftp/undionly.kpxe -O /tftpboot/undionly.kpxe

I originally thought that the problem was solved by upgrading the Kernel and changing the permissions of ipxe, but the problem was solved by getting another undionly.kpxe. But I don´t know if this boot file is reliable.

The only thing i know, is that after this, if i write exit in ipxe, the fog works. But i need to solve this.

@luislesi Why does it fail on the first DHCP request is the main question I suppose…

Maybe spanning tree /port fast setting on the switch? Please search the wiki and forum for this.

luislesi · Jul 21, 2016, 10:37 AM

@Tom-Elliott

I still don’t understand why computer reboots with the original undionly.kpxe that comes with the fog installer (1.2.0) and when i get the undionly.kpxe from https://svn.code.sf.net/p/freeghost/code/trunk/packages/tftp/undionly.kpxe
it works but i have to write exit in IPXE.
You can see it in this photo:
https://goo.gl/photos/GV6XxJUgdhqRAxgg6
I will try to do spanning tree /port fast setting on the switch like @Sebastian-Roth said but i think this is not the reason.
Is there any script that i can do to automatically exit from IPXE?
Thanks

Tom Elliott · Jul 21, 2016, 10:40 AM

@luislesi If I had to guess, if you go to the browser at url (Making adjustments for your environment)

http://10.1.8.1/fog/service/ipxe/boot.php?mac=00:23:7d:b9:2d:f2

What’s output to the browser? My guess is it’s missing a “boot” line.

Tom Elliott · Jul 21, 2016, 10:49 AM

@luislesi Does it only show the menu IF you type exit, or is exit needed only presented when the host is tasked? The Reason I ask: The picture from earlier shows the host was in a task.

luislesi · Jul 21, 2016, 10:57 AM

@Tom-Elliott

Fog stops in IPXE even when i just want to get to the menu.

Tom Elliott · Jul 21, 2016, 11:27 AM

Are you using undionly.kpxe or undionly.kkpxe? Could you try ipxe.pxe?

Is this on ALL machines, or just this particular model?

Is it ONLY this machine itself and all others work?

I’m just trying to get all the info.
