John -

Thanks for the file.  In the extracted folder I've got (the NT version),
there is absolutely NO documentation.

Everyone else:

While John did get me the M to RTF, it is extremely sparse, and doesn't
begin to address the interaction of flexresp with stealth sniffing.  Is
anybody out there using it yet?  Or, from another angle, does anybody know
if it's possible to transmit packets from an interface that has no IP
address assigned?

Thanks,
Dave

README.FLEXRESP should be in the rot of the extracted snort folder. I have
included it for you just in case :) I haven't used in for real yet, so i
can't help you there :(

I even converted the file from Unix to DOS for you.

hth,
John

react/flexresp


Hello all.

I'm in the investigation/learning phase.  Soon I'll be implementing a
firewalled internet connection for my company, email server in the DMZ,
Snort sensors at a couple of key spots - the whole kit & caboodle.  I
think
I'm getting a pretty good grasp of Snort basics, or at least as much as I
can without actually building the boxes & putting them through their
paces.
I'm planning on running Snort on NT, until I get the firewall stuff under
control and dive back into *nix.

I am a little confused about the "react" option and the flexresp module,
especially as it relates to running Snort on a stealthed interface.  If
there is no stack running for the interface, can flexresp still transmit
the
reset packets?  Although I'm far from being an expert, that just didn't
seem
possible to me.  Or, if I want to use stealth, do I need to give up on
using
react?

Also, I tried searching the mailing list archives for similar questions,
and
saw a couple of responses along the lines of "read the flexresp README and
all will be clear".  My problem is, I searched www.snort.org a couple of
times, and cannot find a README for flexresp.  Does anybody know if this
would be found elsewhere on the net?

Thanks,

Dave
