Hi,

I have a couple of questions concerning the port scan function of
snort;
Is there a way to configure the different variables of the
`preprocessor flow-portscan:` in the snort.conf file so that ;
- It display a sample of the port scan in MySQL or in a Log file?
- In the case of an IP scan, It display the total number of host scan
by the source IP in the sequence?


Following is my configuration of the flow-portscan: 

preprocessor flow-portscan: \
       scoreboard-rows-talker 1000000 \
       scoreboard-rows-scanner 250000 \
       unique-rows 1000000 \
       server-rows 65536 \
       scoreboard-memcap-talker 25165824 \
       scoreboard-memcap-scanner 6291456 \
       scanner-fixed-threshold 15 \
       talker-fixed-threshold 15 \
       scanner-sliding-threshold 40 \
       talker-sliding-threshold 30 \
       scanner-fixed-window 15 \
       talker-fixed-window 30 \
       scanner-sliding-window 20 \
       talker-sliding-window 30 \
       talker-sliding-scale-factor 0.50 \
       scanner-sliding-scale-factor 0.50 \
       src-ignore-net [192.168.1.1/32,192.168.0.0/24] \
       dst-ignore-net [10.0.0.0/30] \
       tcp-penalties on \
       server-watchnet[10.10.10.10/16] \
       server-ignore-limit 500 \
       server-scanner-limit 500 \
#      alert-mode all \
       alert-mode once \
#      output-mode msg \
       output-mode pktkludge \
       server-learning-time 3600


Thanks for your help

Patrice
