Good day Martin,

You had a question in regards to gPXE.  Are you aware that there is a
gPXE mailing-list?

http://www.etherboot.org/wiki/mailinglists
http://etherboot.org/mailman/listinfo/gpxe

You asked about how the DHCP service informs the PXE client that it
should download the file "undionly.kpxe".  The DHCP service informs the
client of this in the boot filename option (option 67).

I believe that you are not performing a full tcpdump capture.  By
default, tcpdump only captures 68 bytes from each packet.  Your DHCP
transactions might therefore be truncated.

tcpdump -s 0
