Re: Generate alert but not log packet data

Sorry, I meant that I want a couple of rules to just alert and not log. I do want all the other rules to log the packet 
data.  I have created a couple of alerts that I just need the alert data for and in the interest of saving some disk 
space I would like to disregard the packet data and not save it.  However I still want the packet data from all the 
other alerts just not the two custom rules I wrote.  Is this possible?

Thanks for the previous response.

Hi,

Hello


Is there a way to generate an alert for a snort rule but not actually 
log the packet data.  It looks like there is an option to just log the 
packet and not alert but not vise versa.


Yup sure is........

(root@cerebro)(~) /usr/local/bin/snort -?
       
[...snip...]

- -N         Turn off logging (alerts still work)
