FOG menu not showing up on some machines after DHCP server rebuild

Could not start download: operation not supported

This is one of the most errors you can find being asked about in the forums. Have you read through a couple of those? Mostly it seams to be a messed up DHCP setup - failover or something. Please make absolutely sure your DHCP server is configured correctly and best if you can use wireshark to confirm it is sending out the right information. Feel free to upload a packet dump captured with wireshark on your DHCP server (display filter bootp || tftp) and we’ll have a look too.

Thanks for the replies. Yes, I have looked at similar issues on the forums to the point of pulling out my hair in frustration. I agree it sounds like an issue with DHCP since it worked with my old DHCP server and now it doesn’t with my new one. That is why I was looking for some guidance beyond the settings I have already taken care of (Options 66 and 67). I am not opposed to upgrading to 1.3.0 but l don’t feel the problem is specifically with the FOG server. I am at the point where my labs have to get imaged though and anything is worth a shot…

Part of me wants to say I had a specific vendor class defined in the DHCP server, but it has been so long since I setup the one that worked before it crashed that I don’t know for sure…

Thanks,

Let me add… FOG is on an Ubuntu 14.04.2 server. My boot partition is 235MB and 99.6% of it is being used. Is it possible that is causing the issue?

Thanks,

Thanks,

IF that is causing mysql to die then yes.

Web interface for FOG Is fully functional, so I was guessing that it wasn’t impacting things. I can dig into that more and see what files I can delete to clear up space though. Like I said, I am at the point where I just need it to work so I am willing to try anything.

@Jay-Bosworth really the answer is to setup wireshark to capture the dhcp communications (for dhcp a mirrored port is not required as long as the dhcp server, target computer, and the wireshark computer are on the same subnet). The process is pretty simple start wireshark capturing, pxe boot the target computer, at the target computer error, stop wireshark recording. Then review the dhcp process in wireshark. If you get lost post the pcap here and we can take a look at it.

[Jay Bosworth]

Okay thanks, I will work on installing Wireshark on a laptop here. I freed up some pace on my boot partition, it didn’t make a difference.

Please reboot the fog server once the space is available, just to be sure.

[Jay Bosworth]

Rebooted as requested, still exhibiting the same undesired behavior. Working on the Wireshark capture right now.

[Jay Bosworth]

This is my first time using Wireshark so I am not really sure what I should be looking for. I apologize for being totally lost at this point.

I filtered on the MAC address of the client that I am having issues with.[0_1471959801565_wireshark.pcap](Uploading 100%)

@Jay-Bosworth for some reason your upload didn’t work as expected. Could you try again?

[Jay Bosworth]

Yeah let me try again, I think it said something about me not having privileges, but here goes…[0_1471963844264_wireshark.pcap](Uploading 100%)

Yeah, “You do not have enough privileges for this action”

@Tom-Elliott Any idea why Jay is not allowed to upload a pcap file?

[Jay Bosworth]

I think it might be because my reputation is only 1. I could be wrong though.

Sometimes it just doesn’t work. Just re-try is what I do.

Nope, just tried six more times there…

[george1421]

@Jay-Bosworth pcap that Jay was trying to post.
[edit] it contained more communication information that requested (and some stuff that shouldn’t be public). Jay I’ll post what I need you to do to create a new capture. [/ edit]

@Joe-Schmitt do you know why Jay can’t upload the same file that George can?

When I was younger, my mom called me “a unique person” quite often. Its probably that…

I removed the upload pcap file since it contained things that the general public should not see.

[Jay Bosworth]

Okay, thanks, I was afraid of that. I tried to filter it just to the MAC address of the client. I had a feeling it wasn’t enough though.
