@bakgat First look inside of /var/log You should see some files in there with the name fog_error_[version].log Errors from the installer are redirected to these files. Post the last few lines of those files (or the whole log). It’ll help with figuring out what’s going on.

The dhcp configuration file on CentOS 7 / Fedora it’s located at /etc/dhcp/dhcpd.conf
You might also try to install dhcp manually. on CentOS 7 and Fedora 19-21 you’d use yum install dhcp, on Fedora 22 and up it’s dnf install dhcp

You might also see what is written for start and end ranges inside of /opt/fog/.fogsettings if that file exists.

@bakgat As far as I can tell the options 66 and 67 in the bootp.plist are base64 encoded. Trying to decode (e.g. www.base64decode.org) I only get a sensible result for option 67 (‘undionly.kpxe’) but not for opt 66.

The other thing I notice is that the packet you posted is a request (‘Message type: Boot Request (1)’) from a client machine. You don’t see the options in a request only on replys. See if you can find the answer from the server. DHCP goes like this: Client-Discovery, Server-Offer, Client-Request, Server-Ack (https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol#Operation)

So you should actually see at least four DHCP packets! If you don’t see any reply DHCP packets from the server I am wondering if the bootp service is actually started?!
