SOLVED Quick Host Registration not working on FOG 1.5.3

  • I am setting up a new FOG server using Ubuntu 16.04.4 and FOG 1.5.3. I tried registering a host to test things out. There were a few errors here and there, but at the end, it appeared that it successfully registered, but it is not showing up under List Hosts. I also tried to do a Full Registration and that didn’t seem to work either. I have not tried another machine yet. Any ideas on why this is happening?

  • @tom-elliott Thanks Tom! I couldn’t find the path to the ‘’ file, but I renamed the .fogsettings file under /opt/fog and reran the installer and that did the trick!

  • Thanks @jdeverse for the remote session and letting me figure out the issue on your systems.

    I can say I’ve corrected the problem and the fix is pretty simple for everybody, due to me making a mistake, originally in pushing up 1.5.3. I forgot to add an argument to my script that makes it look for the binary release files. What’s good about that, is it means all you should have to do to fix the issue, now, is re-run the installer. I was able to find the problem. This was related to the lshw having a bug that is still, to my knowledge, not fixed.

    When using lshw -json it creates a non-well formed json string when used with the lshw class statement. (My command is lshw -c network -json).

    I was able to fix this by removing all spaces in the output string, and remove the trailing , (hence the , messages seen on screen.) It also fixes the MSDM issue.

    1.5.4 will have the proper binaries laid out and should be released pretty soon as it fixes the CentOS 6 php-fpm usage issues.

  • @jdeverse No need. Mind seeing the chat bubble? I can chat more realtime with you.

  • Hello Tom, In this case it was an attempt to fix our production server, so while the install file was clean, I did reinstall over an existing system. I can create a separate 100% clean install to test with.

  • @jdeverse If it was a 100% clean install, and you ran the installer AFTER I requested the removal of the file, you shouldn’t have anything to worry about.

  • Hello, I’ve got the main server and some storage nodes. We were working through some other issues so I think we used GIT to install the latest yesterday. After your recommendation today, I grabbed the Fog tar installer directly and re-installed.

    Brings up a question, the procedure you outlined, was this for an existing install directory, or was it to be performed as a matter of fact, even on a freshly download file?


  • Mod note: I’ve moved to bug reports as this is getting way too many hits to be considered less than such, though I don’t know where the issue is at quite yet.

  • @jdeverse This is before or after removing the installers file?

  • Happy to offer our resources here at the Nye County School District. Below is the output of uname -rm


  • From the debug can you run the command uname -rm

    Maybe I can do a remote session with somebody having the issue as well to try to determine what’s going on.

    @jdeverse Excellent this tells us that the kernel is OK since it is showing us eth0. This will allow the developers to focus on the inits (virtual hard drive) & scripts and not spend time debugging the kernel.

  • Hello, we are having the same problem, just popped up today. Hosts have to be registered prior to deployment, we are unable to perform a full or quick registration. The same message is shown “No Viable MAC found”

    This is happening on Dell desktops, however, I’ve pulled the requested information from a virtual guest. I have two screen-shots attached.

    I would like to add that one change we made in the last 24 hrs besides the move to the most recent version was to fix DNS so the fog server could resolve the host names of hosts added to the system.

    If reverting the inits doesn’t resolve the issue lets do this to collect a bit more information.

    1. Manually register one host by going into host management and entering the details for that test host.
    2. Schedule a deployment (doesn’t mater what since we will never get that far) but before you schedule the task make sure you check the debug check box then submit the task.
    3. PXE boot the target computer. You may get warning messages along the way about IP addresses and such. After a few enter key presses you should be dropped to a linux command prompt on the target computer.
    4. When you are at the FOS linux command prompt key in
      ip addr show
    5. We need to see if eth0 is listed and it has a mac address. If eth0 is not there are there entries like ensXXX where XXX is a number?
    6. If there are no ethernet adapter listed then lets key in this command
      lspci -nn | grep thern
    7. This should return the name of the network adapters detected in the system. As an example, this is what is returned on my laptop.
    00:19.0 Ethernet controller [0200]: Intel Corporation 82579LM Gigabit Network Connection [8086:1502] (rev 04)
    1. Post the results back to this thread so we can understand what FOS is seeing on your hardware.

    I’m also having the same issue except with a HP ProBook 650. I’m on the same version of Ubuntu as OP and FOG as well.

    I ran the suggested command and then ran the installer again but I’m still having the same issue. Any suggestions?

  • Please run:

    rm /path/to/fogprojectinstaller/

    Please rerun the installer then. I’ve reverted the init’s to 1.5.2 inits. It will essentially replace all the binaries needed, inits, kernels, client (nothing changed from 1.5.2 to 1.5.3 for the client) to that from 1.5.2.

    I’m not able to replicate the problem, but there seems to be enough people having the issues that it’s warranting this quick change.

  • I am also getting the “No Viable MACS to use” error. Also getting an error creating epoll and also the parse error. Let me see if I can get more information on the errors.

    I tried manually adding the host through the web interface and was able to get to deploy image. However, it hung on “Erasing MBR/GPT”.

  • I’m having the same issue. I have tried quick register/full register, also tried different client devices. Even wiped and reinstalled FOG 1.5.3 on Ubuntu 18.04 LTS instead of CentOS 7. Still having the same issue.

    I recorded the process I did when trying to register the host here:

    I too receive that error, nic is integrated, my model is Dell Precision M4700
