empty logs..how come ??

["Bart Decker" <decker78 () hotpop com>]

I recently configured Snort...as a newbie i don't know all the ins and outs
and maybe i didn't get the whole IDS story .
I'm portscanning myself crazy , but i can't see anything in the logs . They
stay empty all the time .
 
any ideas ? (i use iptables on the linux server )
 
 
Starting with :
 
snort -v -c  /etc/snort.conf -D -i eth0
 
Snort.Conf 
 
 
var HOME_NET 192.168.0.1/24
var EXTERNAL_NET any
var SMTP $HOME_NET
var RULE_PATH /root/Snort_Rules
 
preprocessor frag2
preprocessor stream4: detect_scans
preprocessor stream4_reassemble
preprocessor portscan: $HOME_NET 4 3 portscan.log
