Hi, Steve.  What type of system are you running on, and how many packets
are you generating?

Subject: [Snort-users] High CPU


I am currently testing snort 1.7 and find the CPU to be very high (87%). I
am running 1.6.3 in production and the CPU is about 9%... I've disabled
all
pre-processors, turned on binary loggind and have seen no change... anyone
experienced this?

Thank-you

Would it be feasable for snort's alert messages to contain
some information from the packet that caused the alert?

Answering to myself, this would probably be better handled with
the analysis tool...

I don't get it....

I have Snort 1.7 on OpenBSd

it's telling me it's seeing Packets, it's sending alerts, but I see no data
in mysql....

Subject: Re: [Snort-users] snort pgsql keepalive

I did some checking on Snort behavior when the DB server dies:

Snort 1.7: alerts dropped
Snort 1.8: alert dropped, Snort issues FatalError(), quits

In either case, the behavior is incorrect.  The fact that 1.8 quits
instead of merely dropping (ala 1.7) is immaterial since neither version
will cache dropped alerts.  Thus, without caching there is no
reason to even keep the sensor up, since no logging is occuring
(unless you have other logging mechanisms other than 
the DB-plugin).

I believe that the correct action is to attempt a re-connect
to the DB when Snort detects a disconnect (i.e. when either
the Select() or Insert() fails with the appropriate error code, call 
Connect() again, if this fails only then FatalError() ).

Roman

Hello,

When the sensor got a connection to the postmaster (postgres) and if the
postmaster goes down, the sensor will stop. 

Is there anyway to keep the sensor up and when the connection are coming
back of the postmaster ? like a keepalive and reconnect...

Thanks

alx
