Hello,

Before I have a problem, I installed pulledpork for getting the latest rule
from snort.

After that I restart snort but get this error:

Oct 06 12:25:55 snort[25714]: Detection:

but in the blacklist.rules, there are just ip address per line only

Subject: [Snort-users] Measuring the delay introduced by Snort
Hi,

I am recently using Performance Monitor to dump real-time statistics of
snort.

1. A field of 'uSeconds/Sec' is included with the 'max' option. Given the
definition of 'max' as "theoretical maximum performance that Snort
calculates". Does the 'uSeconds/Sec' refer to the shortest time each
package would take? It's a calculation instead of real-time averaging of
processed packets?

2. Since I am looking to find real-time delay of packets introduced by
Snort, is there any metric that I could use? I have tried a Packet
Performance Monitor and count numbers beyond the threshold, but that makes
me to count the delay events in log file.

3. In perfmonitor, there are the metrics *Drop Rate *and *Perentage of
Packets Dropped*, what's their difference and relationship? I found the
previous thread http://seclists.org/snort/2010/q3/519 but it didn't come
with much explanation.

Thanks,
Jiahua

Greetings,


I am getting the FATAL error on the snort as" *Snort[]: FATAL ERROR:
Event6 type not yet supported!*".  Due to this error the snort is not
generating any alert.

I searched online but didnt get any information about this error. so
anyone know about this ?

Hi all,

Please suggest..!!!


the subject title and reported error is not your problem...

the above line is your problem...

(└$O)!


which is further confirmed by the above line...

the solution is to use the proper command line options and parameters in
the correct order...

Bill is correct on his statement regarding the model type and we support
several different methods for spreading the traffic, talk it through with
the Endace support people.



If you have any problems talking to them contact me directly and I will
see what I can do to assist you.

Which DAG are you using?  The model determines the number of interfaces
(and how) you can distribute your traffic.  Admittedly, you'll probably
only need 2.   On a modern box, 250M is a pretty safe place for snort to be
for each instance.  You'll often start seeing problems when you push past
300M.

Running multiple Snort instances without a method of packet distribution
/ load balancing will not achieve what you are after. Your best choice
would be PF_RING.

Greetings

I'm new to the community and need some guidance.  I have a Dell R720
with plenty of memory, CPUs and storage.  I'm using an Emulex DAG NIC.
Running minimal install of CentOS 6.5 with Snort 2.9.  My CPU usage hits
80% with only 500M of traffic and Snort starts dropping packets.  From what
I've read, I can spin up more instances of Snort on the same interface and
perhaps specify different CPUs for each process.



I start Snort as a daemon via command line for now using:

/usr/sbin/snort -G 1 -A fast -U -b -d -D -i dag0:0 -e -u snort -g snort
-c /etc/snort/snort.conf -l /var/log/snort



I tried spinning up another process with -G 2 but no new processes start
when checking ps -ef | grep snort.



Any direction is greatly appreciated.
