This report identifies hosts that have the TFTP service running and accessible on the Internet.
Our probe tests to see if the TFTP service is accessible and will either return the file that we are asking for or return an error code. Note, we are not testing to see if file upload is enabled.
Also note that unlike other UDP services that we test for, the response from TFTP is often received on a port that is different than what was queried! Probes sent to a host on port 69/UDP may generate responses that source from ephemeral high ports.
