TFTP Problems

[Wayne Workman]

@Arrowhead-IT Tagging your post for the #wiki -and I need to finish that article https://wiki.fogproject.org/wiki/index.php/ProxyDHCP_/_dnsmasq_-_DRAFT and I’ll likely use some of the stuff from that post below.

@Wayne-Workman That makes me feel special Thanks

Not sure if it was already mentioned, didnt see it in a quick scan but I had a similar issue. Make sure that DHCP Option 66 and 67 are enabled. 66 should be the IP address of your FOG server and 67 should be your undionly.kpxe file.

I struggled with it for a couple of hours, hopefully it helps you out.

So today I tryed call the company that takes care of the dhcp server and I don’t know what they did but I got one step forward in the fog server. know I get the following messeges:

PXE - EB: !PXE at 9B85:0070, entry at 9B85:0106
UNDI code segment 9B85:4120, data segment 9552:6330
UNDI device is PCI 00:19.0, type DIX+802.3

then i get:

iPXE initialising devices…

Then:

iPXE initialising devices…ok
iPXE 1.0.0+ (3a02) – Open Source Network Boot Firmeware – http://ipxe.org
Features: NFS FTP HTTP HTTPS ISCSI DNS TFTP VLAN AoE bzimage ELFMBOOT PXE PXEXT
Configuring (net0 00:22:64:ba:2b:56)…

and the the computer resarts and nothing now what is wrong!!!

@bacelo Well on the plus side your target computer is reaching a tftp server and downloading a iPXE boot kernel AND you got past the initializing devices. This is great!! The problem is the spontaneous reboot. This of course is unexpected.

Right after the “Configuring (net0 00:22:64:ba:2b:56)” it should boot into the FOG menu. From the MAC address I see this is a HP computer. What is the model # and what mode is it in, BIOS or UEFI? The undionly.kpxe is for BIOS mode computers. (Actually as I think about it, you would not get this far if you sent the computer the wrong ipxe kernel.

BUT you are having success and getting very close.

[bacelo]

@george1421 the model is dc7800p how do I see if it’s on BIOS or UEFI??

[bacelo]

Could it be that the boot file has any problem how can I see if everything is correct with it!??

Shortly after this part is when the kernel and init are downloaded.
Those are stored on the FOG server here: http://x.x.x.x/fog/service/ipxe/
The local path to them on CentOS 7 / Fedora would be: /var/www/html/fog/service/ipxe/

This is what mine looks like:

Make sure those files exist. If they aren’t there or the file sizes look weird, re-run the fog installer.

Turn your firewall off for testing purposes.
CentOS 7 / Fedora: systemctl stop firewalld
Set SELinux to permissive for testing purposes.
CentOS 7 / Fedora: setenforce 0

Try again.

If you have no luck then, then just re-run the fog installer and see what that does.

Also - a packet capture from the FOG Server during the attempted network boot would be really helpful.

@Wayne-Workman from what I can see I am missing the last two files.

[Wayne Workman]

@bacelo Well, I’m running FOG Trunk and you’re running 1.2.0 right? So it won’t be entirely the same.

[george1421]

@bacelo What you need to make sure is the bzImage files and in the init.xz files exist in this location. This part I’m a bit fuzzy on, since I don’t have a FOG server in front of me right now. I think the next thing that should load is the PXE menu. The linux kernel and inits are loaded once you make a selection on the pxe menu.

does the following url generate a text file (actually the pxe menu)

http://<fog_server_ip>/fog/service/ipxe/boot.php

(I did that from memory so it might be wrong) but once the ipxe kernel is loaded it should try to load the default.pxe config file that is redirected to the URL above. That is what creates the ipxe menu. Again I’m doing this from memory and the egg nog may be impacting what I thought I knew.

[bacelo]

Ok so I got to this point and all the files are there I reinstalled linux and Fog server and it does the same when it should boot the menu the pc just restarts.

[Tom Elliott]

does the screen, during bootup, remain black for a long time? You don’t see the menu, or the menu times out before you see it? This is an important distinction.

[bacelo]

@Tom-Elliott No, this appears:
iPXE initialising devices…ok
iPXE 1.0.0+ (3a02) – Open Source Network Boot Firmeware – http://ipxe.org
Features: NFS FTP HTTP HTTPS ISCSI DNS TFTP VLAN AoE bzimage ELFMBOOT PXE PXEXT
Configuring (net0 00:22:64:ba:2b:56)…
then it just restarts the pc. I am going to update the Bios to see if it could be something with the Bios. Other then that I just don’t know what to do or how to see if everything is correct with the boot file.

[Tom Elliott]

@bacelo Are you willing to try trunk?

I think you’re seeing the “console” error that 1.2.0 users often times had.

[bacelo]

@Tom-Elliott So what sould I do to fix that??

[bacelo]

@Tom-Elliott I am willing to try anything to make this work

[Tom Elliott]

@bacelo Can you hit me up in chat?

I can maybe teamviewer?

[bacelo]

@Tom-Elliott can it be in 1 hour you would save my life

[Tom Elliott]

it sure can be.
