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

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.

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

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?
-
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?
-
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…
-
@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.
-
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.
-
In wireshark, you can apply a filter, and then export the displayed packets.

OK I have a few questions:
- Is the target system an apple device?
- Is 10.60.82.15 your fog server?
- What is 192.168.101.2 and why is it sending a dhcp nak (dhcp rejection)
- Did the target get 10.60.16.119?
crud, that one was an iPhone.
I see another one that is a HP device with a mac address of 00:1b:78:a4:a0:6c
But that one looks like a dhcp renewal. What is interesting is that I seen dhcp ACK from 10.20.88.37 and NAKs from 10.60.82.170, 192.168.101.2 and 10.20.0.101This tells me you have multiple dhcp servers attempting to respond to a dhcp request?
