Here's the output:
Feb  3 15:54:15 edubuntu dhcpd: DHCPDISCOVER from 00:2a:43:ae:30:94 via eth1
Feb  3 15:54:15 edubuntu dhcpd: DHCPOFFER on to
00:2a:43:ae:30:94 via eth1
I got a bit confused because one of the kids must have tried to boot my
upstairs computer too at the same time so I was getting discoveries and
offers to and from both...but in any case, there is definitely connectivity
and the MAC addresses are correct.

pxelinux.0 and nbi.img were actually not in that directory either. I copied
them there but still no results.
