        -d         Dump the Application Layer
        -e         Display the second layer header info
        -v         Be verbose
        -l <ld>    Log to directory <ld>

Now, I'm on a train, so I can't really test it, but I'm pretty sure that

A) it will be verbose and display all the packets (including application and
second layer info) to STDOUT
B) it will also log it all into the <ld> directory.

Ehheh, well, for a start, take a look at the stream4 preprocessor. Having
said that, I'm pretty sure it doesn't log the whole stream. I haven't looked
into this in more depth, but a quick 'grep stream4' in the snort-1.8.4 dir

* added new config keyword to stream4, "log_flushed_streams", which causes
all buffered packets in the stream reassembler for that session to be logged
in the event of an event on that stream (must be used in conjunction with

So, I guess  that'll sort it...! If it doesn't, then use tcpdump in
conjunction with it and throw man-hours at it...! :)

Ok, lets check this a bit more.  If you use a 'snort -vade -i qfe2' and run
scans, do you see the traffic?  Where does this traffic come from?  A third
machine?  If just run the qfe3 instance (as above), does it log?  Running a
'snort -vade -i qfe3' while scanning--Does that show any data?

It all depends.  :)  'Not Possible' just means someone else hasn't done it
yet.  ;-)

It's very possible that someone is synflooding someone else using your
IP as the spoofed src.
