I had fog 0.28 working good on ubuntu 9.10, but it broke - i assume because of an Ubuntu automatic update. I have experienced the same problem.
Anyway, last week, I set up a new fog server with Ubuntu 10.04 and fog 0.28. Everything went fine, (web ui works) but now i cant pxe boot. I have a server 2008 r2 server which is doing DHCP, and fog isnt doing DHCP.
I have set up the 066 and 067 scopes, they should be fine. but when booting fog, on any computer (tried different computers) i get file not found errors.
I turned the fog server off, and the same error occurs, so i presume that it is not the fog server.
I have noticed that when you try to change various setting on the windows server dhcp server, it says that the remote procedure call failed. try to apply the setting again, and it works. I am thinking the dhcp server may be stuffed?
We also have WDS set up. I noticed that it hasnt been working for a while, even with the correct scope settings for it in place.
One interesting thing is that, when i finished installing fog, i rebooted the windows server to see if that made a difference. for a few minutes while the server was booting, everything worked fine - but then fog stopped working again. I have tried to repeat this, and it wouldnt happen again.
I wont get to use it again till thursday, however the fog website says that a new version of fog will be released on tuesday. I will try reinstalling ubuntu, and using it.
But does anyone have any ideas as to what may be causing the problem?
Thanks for reading this, and for any help you may offer.
