heu petite question, tu as la même erreur si tu mets un autre port dans l'option proxy svp?
car par défaut c'est le port 8080 qui est dans le code de l'option proxy...

Bonjour,
Je t'écrit en direct car le Français est plus facile pour moi.
Peut être quelques infos utiles dans ses liens pour toi:
http://snortattack.org/node/265
http://cvs.snort.org/viewcvs.cgi/*checkout*/snort/Attic/sp_react.c?rev=1.10&sortby=rev
Ca ne fonctionne pas du tout ou tu cherches à optimiser? (car je crois qu'il
te manque dans tes rules snort: la direction et pas <>, puis le
flow:to_server...)

I don't know, I don't run Snort on Windows. I don't run the react keyword.
 I was basically saying that your format is correct in your rule, maybe
someone else
can pipe in and give you an opinion as well.

      Is it working on Windows as well as on Linux (idem for Mozilla and
Internet Explorer) ?
      What kind of message is supposed to appear on client Web browser
(html, pop-up, ...) ?
      Thanks,

/** please make sure you cc the snort-users group **/



It looks like you have the field typed correctly, I am not sure why Snort
isn't accepting it.

Hello Joel,



Thanks for your answer.



Did you build Snort with --enable-react at ./configure time?

è Yes, I did, and no error at ./configure, make, make install time

Hello,

I'm using snort 2.8.5.3 inline, and i try to set up a msg with the react
keyword for users (ip) which trigger the following alert :

alert tcp any any <> $EXTERNAL_NET 80 (content:"GET"; \
msg:"Notforchildren!";sid:111000101;react:block, msg;)

The alert is seen in the snort log, but not in the user's browser.
(I suppose that the content of the msg send to the browser is
"Notforchildren!")

Then, I'v tried with

alert tcp any any <> $EXTERNAL_NET 80 (content:"GET"; \
msg:"Notforchildren!";sid:111000101;react:block, msg, proxy 8080;)

I don't understand the modifier "proxy". It is a local port which send the
msg to user or is it the web proxy ?

And the following error occurs when starting snort :

ERROR: /etc/snort_inline/rules/local.rules(7): invalid react modifier:
proxy 8080

Question : How snort send message to browser ? Does it with any Os or
browser (IE, Firefox...) ?

Thanks in advance,

Al.
