Did you comment out the lines following the    preprocessor sfportscan
line?
                        memcap { 10000000 } \
                        sense_level { low } 


A few lines about    preprocessor sfportscan  is a description of

Thank you for your reply.  If I comment out 
# preprocessor sfportscan:
the snort service can not be started.  Also, what's
the syntax to ignore this host from sf portscan?

Thansk for your help,

John

Hi all,
 
Since I did not get any reply on this, is there
any way to suppress or
pass this alert?
 

Suggestion: look at the ignorehosts option for
portscan.

Pass definitely will not work. Since pass is a rule,
it can only work if the
offending traffic is matching a rule.

You might be able to suppress it, but you'd probably
wind up having to suppress
all portscans...

It's generally best to configure your portscan
plugins properly in the first
place. Actually, if you're monitoring an internal
LAN, you'll probably just want
to turn it off or turn the thresholds way up.
