There is a bug in sp_react.c.  The attached patch will fix it.  Apply with:

cd src
patch -p0 < react.diff

If you just want to use 8080 as the proxy port, you can omit the option altogether and skip the patch as that is the default.

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,
Alexandre

/** 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?

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

Br,
Alexandre

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.
