  Heaven, I'm glad you are seeing that, too. It really gave me headaches.
  In the last four weeks I had (privately) two ssh "incidents": one
  originating from Korea, one from Germany. The first was clearly a
  person trying to get in, taking a deliberate taste in the (existing)
  test account (without success). The other one was "next door", someone
  trying to get in as root (no success either). I only reported the
  second one.
  Only after the first playround the test/guest attempts started so
  I was starting to think that whoever was probing my host from Korea
  was probably going with that. Now that my host is out of focus, I'm
  really relieved. :-)

  Has anyone tried to capture that with an honeypot? I'm considering
  that for my own but lack the proper enviroment.

  Cheers,
