Deluge?  I would be ecstatic if we only saw 8k rejections per
day.  Our servers here typically reject closer to 80i, and
several of our ISP customers reject about 2,000,000/day.

What I have seen in the last week or so is a huge increase in the
number of sshd and proftpd dictionary attacks, some of which are
in the hundreds/second for hours at a time from the same IP.
