[steve at penguin steve]$ fgrep tftp /etc/services
tftp            69/tcp
tftp            69/udp
tftp-mcast      1758/tcp
tftp-mcast      1758/udp

However, upon looking into it more, you're right.

I guess I should do a little research next time before opening my mouth,
eh? :)  It seems kind of silly that it is built on UDP though, I'm not
sure why they limited it by using UDP.  I don't see any great benefits
it gets from using UDP over TCP, especially since it apparently tries to
implement some of the features of TCP.
