This did work for the 760’s and 780’s as well. Thank you very much for the help Jbob, Junkhacker, and Tom

Jbob thank you that seems to be working on the 755, I will be able to test on the 760 and the 780 later this afternoon.

So what has changed from version .32 where this worked with no problems on our network to now? We do not have STP enabled on our network. All switches are Extreme Networks brand

I can now add a third model to my list that will not work. So total that I have on my campus that will not register with fog include Dell optiplex 755, 760, and 780. They all three give the DHCP/BOOTP Reply not for us error.

After letting them sit for awhile they do go into the registration process then do what is in the picture.[ATTACH=full]1264[/ATTACH]

I have tried both undionly.kpxe and undionly.kkpxe from official 3.14.2 kernel as well as the unofficial 3.16.0 kernel. They both still give me the DHCP/BOOTP Reply not for us message on the Optiplex 755 have not tried on the 760 yet.

In Ubuntu 12.04 and later the tftp starts to soon after a reboot. I have had good success with doing the following.

sudo gedit /etc/rc.local

then add the following line
/bin/sleep 30 && /etc/init.d/tftpd-hpa restart

I have a lab of 1600’s that is currently being deployed. Once it is done I will try that one and let you know. Is there a process I need to do to undo the chainloading of pxe to ipxe or will it matter?

I am not sure on portfast, STP is disabled but there is plans to enable extremes version of STP called ELRP.

There is a tftp password setting under other settings>>fog settings as well, toward the bottom of the list.
