Fog Boot Menu only works once
-
Hi,
Firstly, just want to say a huge thank you for such a brilliant piece of kit.I have Fog Trunk 7492 running on CentOS 07.
I am using the kitchen sink config with kernel 4.5.3
I have two machines to image the Dell OptiPlex 7010 and the OptiPlex 3020.
The OptiPlex 7010 boots to the Fog menu perfectly and works with multiple reboots.
The issue I am having is with the OptiPlex 3020. It boots to the Fog Menu once and then if I reboot the machine it hangs at ‘Please enter tftp server:’ if I enter the address it does not boot to the fog menu.
If I reboot the FogServer the 3020 will boot fine first time and then fail the second time again. Could you possibly offer any guidance?
If you need any information let me know,
Thanks,
Tom -
Did you build the kernel yourself?
-
Is the fog server functioning as the DHCP server for the 3020?
Without putting too much thought into this, it sounds like a networking issue. But its not clear yet why rebooting the fog server fixes the issue (once). We will need more information before we can narrow down the problem.
-
It does sound like a networking issue - but it could possibly be something else. We do need more details as George said.
-
To me this sounds like SELinux is the issue.

Hi,
Thanks all for the replies. The Fog Server is indeed functioning as the DHCP server and I did build the Kernel myself however I found the same issue with the original kernel and have tried several different ones all with the same effect!Thanks,

@TomBagley What’s the output of
sestatus? What aboutiptables -L -n? -
Hi Tom,

@TomBagley Considering you have to enter tftp server address, it is likely you have another DHCP server on your network (likely your modem), which might be interfering.

I understand your thoughts Quazz and although I do have another DHCP server I wouldn’t have expected it to not work so consistently if that was the case. I’d expect intermittent issues rather than it always working the first time and not the second.

@TomBagley This will most likely be due to the dhcp leases that are handed out allowing the other DHCP server to reach it before FOG has a chance.

Depends on your network setup. with IP Helpers - you wouldn’t notice any issues at all. If one DHCP server is set as authoritative and another is not, you wouldn’t notice any issues at all. And it too could be that the other DHCP server is just able to reply faster, consistently.
If two co-existing DHCP servers within the same broadcast domain are not properly configured to work with another present, it’ll only cause you issues.

My networking manager has explained that the Fog Server and clients are on a Vlan completely separate from the rest of the network. Could this still be interfering?
Thanks Quazz,

Got you thanks all for the rapid response it is much appreciated. Going to turn the Fog off and see how the client behaves. Will let you know how I get on.

That’s done it - solved! Thank you ever so much! Time to slap my network manager for not blocking the DHCP
Have a nice evening guys.

@TomBagley You could ask him to modify it to support fog. We have very detailed guides in the wiki. Please pass these two links to your network manager:

@Quazz Kudos to you for knowing what the issue was.
