Yes, it was a small part of my pf.conf. Anyway i'm trying on another machine 
with a much smaller configuration with the same results. I think it should be 
enough for bruteforceblocker to work

table <bruteforce> persist file "/var/log/bruteforce"
# options
set block-policy return
set loginterface bge0

# scrub
scrub in all

# filter rules
pass all

block in log quick inet proto tcp from <bruteforce> to any port ssh

Yes, they display as expected

No ALTQ support in kernel
ALTQ related functions disabled
scrub in all fragment reassemble
pass all
block return in log quick inet proto tcp from <bruteforce> to any port = ssh

Yes, i did

No, i don't see any of these messages, the only message i see is the start of 
the log:

!!!!!!! log started at Wed Oct  5 18:53:23 2005 !!!!!!!

I cannot figure what's the problem, the bruteforce table remains clean after 
the tests, but the bruteforce blocker is running in the system apparently 
whithout any problems as i have checked with ps.
