Merci pour les liens, une autre personne m'a filé un patch je l'essaierai ce soir ou demain matin et je te dis ce qu'il en est.

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 was basically saying that your format is correct in your rule, maybe someone else can pipe in and give you an opinion as well.

Did you build Snort with --enable-react at ./configure time? ==> Yes, I did, and no error at ./configure, make, make install time Br, Alexandre De : Joel Esler [mailto:jesler () sourcefire com<mailto:jesler () sourcefire com>] Envoyé : mardi 27 avril 2010 14:52 À : RMS, Admin Cc : snort-users () lists sourceforge net<mailto:snort-users () lists sourceforge net> Objet : Re: [Snort-users] snort 2.8.5.3 with react keyword not sending msg to browser Did you build Snort with --enable-react at ./configure time?

(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...) ?
