Ahem. I could not even do anything in a console. I had to pull  out  the
plug. And within 5 minutes my /var partition  was  full.  Can't  imagine
that that can be usefull.
I had all the logs I ever wanted of this attack and a lot  more.  And  I
had to get online again and be able to use my machine. And  to  rid  the
#openbsd-channel of that pest.
Of course I am not suggesting a permanent stop of logging.
Looks like you never have been ddossed.
