This is because they are looking for IoT devices where people never change
the default usernames and passwords.  Many of them have an open port 23 for
legit reasons, while others have 23 open because the default os install
does not disable it.

Ironically, maybe, I have not had as much trouble with unwanted port 23
traffic tying up the board as I have with unwanted port 22 (ssh) traffic.
They cannot log in, but they tie up multiple sessions trying, so I changed
that one from the default.
