Thanks for your reply... Q: "do you have those specific rules enabled?"A: My understanding is that by removing the # character the preprocessor is activated. I am not aware of a sfportscan.rule file. scan.rules is not commented out (no # in front of it) Q: "do your scans follow the specific portscan rules that snort has in the preprocessor?"A: preprocessor sfportscan: proto { tcp } scan_type { all } (...) or preprocessor sfportscan: proto { all } scan_type { all } (...) does not generate alerts for nmap -sS <dest_ip_address>
