PXE-T36, PXE-E36 Sync Error.....NO Results



  • I have been using FOG for about a week now. It works great with the exception of 2 things.

    1. Acer 5635 will NOT pxe boot. (Maybe it is that yucky Atheros NIC.

    2. I rebooted my FOG “server” this morning and registered some laptops.
      Then, I went to deploy the image and upon reboot none of the laptops will pxe boot now.
      They all give me the following error: PXE-T36 Synchronization Err-6
      PXE-E36 TFTP Error

    Any ideas?

    Try a different kernel, you may want to include the drivers and make your own, it’s surprisingly easy, most problems stem from the fact that the drivers aren’t in the kernel, they’ve tried to put as many as possible in there but some are still missing.

    You can change your kernel in your Fog Management screen and try an older kernel and see if that helps, if not try these step below.

    [INDENT][B]How to Build a Custom Kernel for FOG Server using Ubuntu 12.04[/B]

    First, make sure you have [B]G++ (GNU C++ compiler) and QT4 (Qt 4 Designer) [/B]installed through the Ubuntu software center.

    Next, pick a Linux kernel you want to use to compile the kernel at [URL=‘http://www.kernel.org/’]www.kernel.org[/URL]. (Used linux-3.10-rc2.tar.xz for this document;[url]https://www.kernel.org/pub/linux/kernel/v3.x/testing/linux-3.10-rc2.tar.xz[/url]) Download the file to the ‘home/user/Downloads/’ directory. (default)

    Then, download the Fog installation package installer. (Current version 0.32;[url]http://sourceforge.net/projects/freeghost/files/FOG/fog_0.32/fog_0.32.tar.gz/download[/url]) Make sure to download to the ‘home/user/Downloads/’ directory. (default)

    Now we will extract the files to their proper locations.

    First, extract the FOG installer to the download folder. (see below for command)
    [B]sudo [/B][B][FONT=Tahoma]tar -xvf /home/user/Downloads/fog_0.32.tar.gz[/FONT][/B]

    Then, we will want to extract the kernel to the ‘/usr/src/kernels/’ directory. If the directory does not exist create it. You will also need to copy the tar.gz file to the kernels directory in order to extract properly. (see below for commands)
    [B]sudo mkdir /usr/src/kernels/[/B]
    [B]sudo cp /home/user/Downloads/linux-3.10-rc2.tar.xz /usr/src/kernels/[/B]
    [B]cd /usr/src/kernels/[/B]
    [B]sudo tar –xvf linux-3.10-rc2.tar.xz[/B]

    Now we can either use CORE or Kitchen Sink to create the kernel.

    To use [B]Core[/B] use the following command:
    [B]sudo cp [/B][B][FONT=Tahoma]/home/username/Downloads/fog_0.32/kernel/core.config /usr/src/kernels/linux-3.10-rc2/.config[/FONT][/B]

    To use [B]Kitchen Sink[/B] use the following command:
    [B]sudo cp [/B][B][FONT=Tahoma]/home/username/Downloads/fog_0.32/kernel/kitchensink.config /usr/src/kernels/linux-3.10-rc2/.config[/FONT][/B]

    Once the .config file is copied to /usr/src/kernels/ you can now run the make xconfig command.
    [B]cd /usr/src/kernels/linux-3.10-rc2[/B]
    [B]sudo make xconfig[/B]

    Now the kernel editor should pop-up after a few seconds. Here is where you will locate and select/deselect drivers you want to load to your custom kernel. (see screenshot for example)

    [IMG]http://i.imgur.com/a49MUxh.jpg?1[/IMG]

    Once you are done with your selections just [B]save and quit[/B].

    Now you have to run one final command to write the kernel file.

    For 64-bit systems:
    [B][FONT=Tahoma]sudo make ARCH=i386 bzImage[/FONT][/B]

    [FONT=Tahoma]For 32-bit systems:[/FONT]
    [B][FONT=Tahoma]sudo make bzImage[/FONT][/B]

    [FONT=Tahoma]You may get a few prompts during the compile, I just used default options (enter). It will take a while (10-30 minutes) to compile the kernel so be patient.[/FONT]

    [FONT=Tahoma]Now that you have created a custom kernel you will need to copy/cut the file to your FOG server.[/FONT]
    [FONT=Tahoma]Go to the [B]/usr/src/kernels/linux-3.10-rc2/arch/x86/boot/[/B] directory to find the new [B]bzImage[/B] file you created. That is the file you need to import to your FOG server kernels directory in order to use it. (You can rename it or use the new kernel as the default kernel for FOG to use if you leave the name bzImage)[/FONT]

    [FONT=Tahoma]The directory where you should paste the new kernel is /tftpboot/fog/kernel/ on the FOG server.[/FONT]

    [FONT=Tahoma]Make sure you assign the custom kernel to the proper host in the FOG management GUI and then you should be able to Upload/Deploy. You might need to add the host manually; you’ll just need the MAC address of the NIC for the host.[/FONT]

  • I have both 12.04 and 10.04 available…Wahtever it was, it started wotking again, but I still have an issue with the Acer 5635 laptops. The will not PXE boot. I could have sworn I tested 2 of them the other day and they worked just fine.
