hey guys,

could you tell me which rule should I set to drop if I wanna block all
port scan?

from my snort.conf:

*preprocessor sfportscan: proto  { all } memcap { 10000000 } sense_level
{ medium } detect_ack_scan*s

if i m right it only detects ack flags without 3w hs. my question is how
to configure it to detect all port scans and which rules to set to drop?
