@Wayne-Workman Wayne!!..Ah ah!!..Savior of the Universe! Finally the solution! It finally works! I think the error is an issue of dnsmasq, since when I tried all of this stuff configuring Fog server machine as dhcp server, all worked fine, and in the dhcpd.conf file, the proper line said “undionly.kpxe”. So, I think dnsmasq is who´s mistaking the name of the file.
Well, what ever, it works!
Thanks a lot my friend! I really appreciate your help.
I don´t know how to tag this post as “SOLVED”. Would you please tell me?
