Hi,

Thanks for all the references. I did noticed OpenFPC and checked that
one out and together with Snorby it's just what I was looking for.

Thanks you all.
Regards,
Onno.

You are better using a tool like these to do full packet capture:
 openfpc

 moloch

https://github.com/aol/moloch

stremdb

Each of these are good choices although right now I use openfpc
(although it is broken for me at the moment :( ) but I want to use
moloch but the requirements for that because of the indexing of
traffic is higher than I can provide it seems.


Regards,
Kevin

        Hi,
        
        Just wondering. I've setup snort and it triggered an alert.
        The alert
        is: OS-WINDOWS Microsoft Windows Shell Handler remote code ...
        sid=1:16414
        
        In snorby it's showing a dump of the payload. But that is only
        of that
        specific packet? Dump is like:
        0000000: 54 f1 c7 e1 57 2a e3 b3 36 c0 ea aa 17   82 aa 2d f0

        Not really readable. ;o) So I was wondering if snort is able
        to generate
        a 'session pcap' when a rule is hit.
        
        I'm running snort with barnyard2 (unified2). Options used are:
        -d and -D
        (and couple of others for conf, user and -l <dir>)
        
        Do I need to add option -b ? (or a complete other program? ;o)
        )
        
        Regards,
        Onno.
