Kernel Update - Web-UI doesnt do anything



  • Hi.

    When trying to update our kernel to the latest versions for 64bit and 32bit, I can open the page to install the kernel just fine, but clicking on “install” doesnt do anything. Page doesnt reload, nothing changes.

    Tried in Chrome and Internet Explorer.

    Is there a way to install the new kernels via command line on our linux Fog server?


  • Developer

    @Taspharel This hopefully helps:

    chmod 777 /var/www/fog/service/ipxe
    chmod 666 /var/www/fog/service/ipxe/bzImage*
    

    Then try kernel update again.

    @Taspharel Please run ls -al /var/www/fog/service/ipxe on your FOG server and post results here.



  • @Sebastian-Roth
    Thanks for your help.

    So, something that has troubled us in the past (auto renames of hosts to names that are assigned to other hosts) was that we use usb3-docking-stations on a lot of our setups. So I assume that a computer that was attached to a docking station when registering with FOG via the client took the Docking Stations MAC Adress and registered it. This may have happened with several clients. Attaching a new computer to a docking station with force reboot hostname change active then changed the new computer to the old computers settings.

    I have been trying to figure out a way to get all the docking stations mac adresses and have fog ignore them, but there seems to be little similarity in the docking stations mac adresses … So for the moment I am struggling with finding out which host uses a docking stations mac as primary mac to make them ignore it.
    I was even considering deleting all the hosts for our rollout today to make sure that they get registered with their correct mac’s - since we have to connect them directly to the lan port for fog to do its thing anyways … but I am worried it might throw more problems than its worth …

    Regarding the Kernel:
    With the working branch fog that I installed a few days ago the problem with the install button (Screenshot: https://drive.google.com/open?id=0B_yYSiicYNIARjQ2eHJXTS1RV28) - it now is clickable.

    But when I clicked on the button I get an error now: https://drive.google.com/open?id=0B_yYSiicYNIAX3Qyek0wZVNMNDQ

    EDIT: Same kernel update error for this user here - https://forums.fogproject.org/topic/10978/uefi-lenovo-miix-320-and-usb-ethernet/2

    And now let’s get back to the initial question…

    @Taspharel said:

    There is no “install” button there. Please take a screenshot of what you see when things go wrong. Just want to make sure we talk about the same thing. Have you tried in Firefox yet? Are you behind a proxy server by any chance?


  • Developer

    @Taspharel I must have overlooked what is really causing this in your case. Sorry for that. Now I found the time to dive deeper and replicate the error message. Though it took a lot of fiddling with the DB. Let me explain:

    • In the logs you see different client IPs. From that and the code I think this is happening when fog-clients want to talk to the FOG server - so this has nothing to do with your initial request of kernel updates (hope we get to that at some point as well!!)
    • What you see in the logs can only happen if you have a client (or in your case several clients) report(s) a MAC address to the FOG server on check-in which is registered for another client as primary MAC.
    • This is why I couldn’t figure out a mysql query to find the entry causing this. It’s not just in the DB but also the clients reporting a MAC that is used by another machine.

    I am still wondering how this can happen. Possibly this has something to do with virtual machines running on those clients? Not sure though.

    Please go ahead and take a closer look at the fog.log on those clients (192.168.43.220, 192.168.43.164, 192.168.43.123, 192.168.43.187 and possibly more). Find the lines that look like this: 10/19/2017 10:34 PM Middleware::Communication URL: http://x.x.x.x/fog/management/index.php?sub=requestClientInfo&mac=E6:FF:3C:83:40:15|E6:2B:28:65:84:12&newService&json

    See if you can figure out if there is an identical MAC address reported by all those clients.

    @taspharel No, it just means that for those hosts (grouped by the hosts’ IDs) you have several MAC addresses in the DB. This is all fine. What I expected to see was at least one entry with hmPrimary set to 1!

    Though this query is not perfect because of the grouping. It might not show the entry I expected to find.

    Please do some DB maintainence. Search the wiki on this.



  • Do I read this correctly in that one of the MAC adresses is assigned to 16 (!!) of our hosts?

    How did I make that happen? :(

    @Taspharel Do you still see those messages in the error log (currect timestamps)?



  • It just says: Empty set (0.09 sec)

    :-/


  • Developer

    @taspharel said in Kernel Update - Web-UI doesnt do anything:

    Error multiple hosts returned for list of mac

    Though I don’t think this is related to your kernel update issue it’s definitely wise to check the database as it seems there is a duplicate MAC entry.

    shell> mysql -u root -p
    ...
    mysql> use fog;
    mysql> SELECT hmMAC, COUNT(hmMAC) c from hostMAC GROUP BY hmMAC HAVING c > 1;
    mysql> quit
    shell>
    

    Post the full output (or a picture) here so we can have a look.



  • I was on RC9, am now on Working Branch from yesterday.

    Kernels are updated with new version yes.


  • Moderator

    What’s your current FOG version?

    Updating FOG also updates the kernels, btw.



  • Sorry … formatting. Thats just a random piece from the log



  • Hei.

    So, I just checked the log and I get A LOT of errors… not sure if any of them has to do with the issue at hand?
