dhcpd.conf is empty when opening nano /etc/dhcp/dhcpd.conf

[wehama]

worked through the "Getting Stratux to work with AirNavigation Pro" and everything worked fine til the point where I need to modify the "dhcpd.conf". The file seemed empty so I just copied the modified text according the "Getting started..." which seems to be the main fault I did. After rebooting I could not get a) a proper connection via WLAN (no internet connection) and b) no connection via AirNac Pro or SkyDemon. No longer be able to connect via terminal so how to proceed from here?

Sorry, my first steps in Linux did cause some trouble, hope anyone can help.
Thanks in advance, Werner
