It's happening here. I've logged thousands of attempts from chinanet
and kornet within the last few days. I've reported (as if that would do
any good) with "Free Tibet" and of course copies of the log - 500K in
one instance(!) but am more interested in just blocking their
entire /24 if need be.

The question is - how?

IP (using whois) belongs to pubnet.ne.kr. I'd send a
heads up email to abuse@pubnet.ne.kr and CC it to ip@pubnet.ne.kr.

If you only see "Failed attempt" then you're probably safe - there are
probably script kiddies running password sniffers or crackers. Note the
port(s) tried - in my case they are non-standard ones - and block them
with your firewall. Check and/or install chkrootkit.

I certainly hope you're not infected, and if so, you'll need to
