Fog wont load past kernal_thread_helper+0x6/0x10

[Tom Elliott]

First and foremost, setup the DHCP Router Address, make sure it points either at the FOG Server, or whatever the DHCP Server address is.

DNS Shouldn’t really matter, but usually it’s not a bad idea to have it setup even if this system is not going to be accessing the internet. Usually, you can set this the Default Gateway of the Router address. (In home routers your Router IP and DNS IP tend to be the same e.g. 192.168.1.1 for the default gateway and dhcp server, as well as the dns)

You need to tell your DHCP Server where it needs to look for the tftp server and what file. In linux, this is usually done through the next-server setting pointing at the FOG Server IP. In Windows DHCP Servers, these are under the scope options. Options 66 and 67 point to the IP of FOG and the file (undionly.kpxe or pxelinux.0) respectively. Option 66 would be the IP, Option 67 would be the file you’re trying to load. With FOG 0.33b, Option 67 should be undionly.kpxe. With earlier versions of FOG it was/is pxelinux.0

You state that you did not install a DHCP server in fog. That’s perfectly fine, but find out how to change the options so it points properly at the file and the ip of the FOG Server.

That part is already done, i did that with the original fog box per your instructions and have not changed anything on the DHCP server.

[Tom Elliott]

So the FOG Server IP on this new system is statically set as the SAME as the “old” fog server?

[viper02]

The only thing different is that i took you advice and did a clean install, with a larger drive

[viper02]

yes same information just a fresh 0.33b install instead of 0.32

[Tom Elliott]

Okay,

So we’ve established that Option 66 is the IP of the FOG Server.
Option 67 is set as undionly.kpxe.

There is no DHCP Router address set in FOG, but that shouldn’t matter right now.

There is no DNS address set in FOG, but that shouldn’t matter right now.

Have you been able to successfully download the file via a command prompt window?
NOTE: YOU MAY HAVE TO INSTALL TFTP CLIENT IN WINDOWS Programs and Features.
[code]tftp -i <FOGSERVERIP> get undionly.kpxe[/code]

[viper02]

My fog is on my ubuntu 12.04 why am I installing the tftp client on Windows?
I have the file in the ipxe folder

[viper02]

Fog installed through script using the wget method from mastacontrola

[Tom Elliott]

You’re only installing tftp client on one of the systems you want to try to image.

This will let us know if the file’s even accessible.

[viper02]

Ok

[Junkhacker]

the tftp client being installed on windows is just so you can test the tftp server on the linux box

[Junkhacker]

have you tested if the file on the tftp server is accessible ?

i ran the tftp and it gave me the following…

[viper02]

What is different between the .032 and 0.33 it seems that the tftp only works when going to pxelinx.0

[viper02]

what is your value for [FONT=Ubuntu][COLOR=#555555]FOG_TFTP_PXE_CONFIG_DIR under fog settings tftp server?[/COLOR][/FONT]

[Tom Elliott]

viper, there is nothing for FOG_TFTP_PXE_CONFIG_DIR set for 0.33b because it’s not needed or used in any way.

[need2]

I about caved my keyboard in with my face yesterday when I made the jump to 0.33 and couldn’t get TFTP transactions to work either. I checked everything, and even did a sudo clean install, but to no avail. Finally I double checked my DHCP settings, and I swear some documentation somewhere told me to use undionly.pxe, when it should be undionly.kpxe . Once I fixed that Option 67 on my DHCP, magically everything worked.

I blame reading the wrong thing somewhere but I know it was likely my own internal processing error.

[viper02]

So i decided to go back a recheck everything including my bosses changes to the DHCP. It appears that it was only changed under server options and not scope options. So yea i’m ready to do the same to my keyboard… After making sure that it was changed on both i was able to successfully pxe boot and i am currently uploading my image to the server… Thank you all so much!! couldn’t have done it with out everyone.
One final question it gives me the choice for part clone or part image, i selected part image but in noticed that during the imaging part clone is running , and its moving along quite slowly.
Either way progress none the less.
