Dear all
I run a ftp site which is being attacked by someone who issue some 1000

how about controlling access via pf?
you can limit the number of connections from the SAME IP and/or
number of connections from the SAME IP over a given time...
Or just block the IP and be done with it?
We use this method for controlling attacks on SSH port 22 but it
could also be used for any type of needed control.
the items of value under pf are:
max-src-conn
max-src-conn-rate
flush
flush global
