Seems that TFTP was not prepared by installer

Ok. Problems that came up with the dhcp-issue were related to the network-card in the fog server.
Strange thing, since the network card worked for some minutes and then stopped even pinging, which worked before.

Changed the network card, built an image from one machine an cloned it to another machine. Everything worked fine.

No comes the fine tuning.

Thank you for your help everybody!

@george1421 It is a physical machine with 1 onboard NIC and (now) one TP-Link networkcard.
Works fine now.

Thanx for the help!
