Thank you all for your kind replies, I am overwhelmed. It is bit disappointing that the reassembled sessions can not be logged by Snort, afterall Snort CAN also work as a packet logger and log in pcap format, then why is it that there is no option to log the re-built packets - a functionality that Snort implements. BTW, I just wanted to have a summary record of each session (initiated with a 3WHS and terminated by a 4WHS) similar to the Snort's summary log packet for portscans - I am not sure how tcpdump or other software mentioned in this thread can do that. It looks like I will have to write one myself. In addition I also wanted to track UDP and ICMP sessions - any ideas on how to do that? All this exercise to build a useful dataset for evaluating my little supervised learning algorithm aimed at intrusion detection - Ah!!!

Do you all think it performs better than tcpdump at writing packets to disk? This never crossed my mine to evaluate before now, as I have only used damonlogger to play traffic out another interface.... If yes, any document on this claim out there? Running to Google now to see if I can't find something on this while I wait for responses ;) --jeremy On Thu, Mar 13, 2008 at 8:40 PM, Martin Roesch <roesch () sourcefire com>wrote:> -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Correction.
