Hi, The sensor is on the inside of the firewall, but it's fairly busy. Tracking more sessions sounds like a good thing... ? Should I bump this up and monitor the performance? ________________________________ From: jesler () sourcefire com [mailto:jesler () sourcefire com] On Behalf Of Joel Esler Sent: March 11, 2009 2:19 PM To: Jefferson, Shawn Cc: Snort-users () lists sourceforge net Subject: Re: [Snort-users] Getting tuned finally! If you increase this number, obviously it will allow you to track more sessions. What is the placement of your sensor (inside or outside firewall?)

I do have some questions about the stream5 preprocessor though. I noticed that I was getting "faults" occasionally, and subsequent messages in the daemon.log about pruning sessions, so I increased the memcap limit until these went away. Is this a "correct" action to take? Also, I noticed that my Open Sessions stats show open sessions to pretty much always be equal to max sessions, which is set at 8192. Should I be increasing this, or is that normal behaviour?
