Aaron,
To my knowledge, tftp does not reference the exports file. It's more
likely that packets are being blocked by a firewall or by tcpwrappers.
I would look in the logs for dropped packet notices or any information
from tftp -- you can boost the logging verbosity with "-v" in
/etc/default/tftp-hpa (on my Ubuntu machine anyway). Look at the manual
page for tftpd ("man tftpd") for more options; it's a very simple daemon.
Try "iptables -L -n -v" to see if you're dropping packets to port 69
from anywhere (tftp uses the UDP protocol).
Look in /etc/hosts.allow and /etc/hosts.deny to see if you have any
tcpwrapper rules affecting your tftp daemon.
Hope one of these ideas helps.
