Okay. solved the host list issue by clearing the tables hosts and hostMAC and then reimporting the csv file.
The PHP error message is gone as well after updating.

After having another go at this with the latest svn build, I finally solved the problem. Or at least I hope I did.

I had the same problem as before with the latest svn release. I changed between different .kpxe and .kkpxe files countless times until I tried something I hadn’t done before. I always used symlink’s to switch between .kpxe and .kkpxe files, but instead of doing that I decided to change Option 67 in the DHCP settings for a change. And it worked!

I’ll try a different client later to see if it really is the fix I’ve been looking for.

Edit: Doesn’t seem to solve the Problem. But I found a workaround. Booting any OS (Live CD is enough) and rebooting solves the problem. I guess it has something to do with the NIC not being shut-down correctly by the manufacturer.

I just wanted to say thank you for the post. Have been all over looking for this answer, as I am new to both setting up a Ubuntu desktop as a Linux server and FOG. Really excited to start using FOG, great piece of software by the way, and give this school district an answer to cloning that doesn’t involve using deploy studio to clone a PC. Thank you again.
