I'm not fimilar with the tftp protocol, all I know is that it uses UDP.
Maybe there's a checksum attached to each packet being sent?
how about sending a packet with the wrong checksum or something similar
that would cause the client to wait for the packet to be re-sent or just request
the file again?...
