Thanks for all the responses! It looks like the primary problem is a
lot of lame servers out there.
As Carlos explained, the IP in question does not resolve with reverse
DNS. However, I would not call that your primary problem: you seem to
have the external interface (on your router, or whatever) open for ftp,
and seem to be getting subjected to a dictionary attack (attempts to log
in with any number of common potential user IDs and passwords). Close
the external interface for ftp, unless you absolutely need it, and let
the firewall handle the job of protecting your ftp server security.
Loud *pop* heard as Mr. Rankin resolves his cranial rectal inversion by
closing port 21 on his router. Sometimes it truly is the forest for the
trees.
