------_=_NextPart_001_01C4E3C7.0C21C731 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable Hi all, =20 I just updated to the latest Snort (2.3.0RC2) and compiled it with the flexresp option. It compiled fine and accepts and understands "resp" rules, however during testing I have created rules using "resp: rst_all" and they don't work. I see my test criteria is found in the alert logs but it does not appear to reset the session. This used to work for me in the past.=20 =20 Afterward I noticed my sniffing interface did not have an IP assigned, so I assigned one and did the test again. That still did not help. =20 I'd like to mess around with sending TCP RSTs when a rule is triggered or some other way of killing a session when a rule is met. Is Flexresp the option I should be using or are there better features now? Just wondering if I should be spending time on flexresp or looking at something better.=20 =20 I looked at the new "inline" features but not sure if this is an alternative? =20 =20 Thanks =20 ------_=_NextPart_001_01C4E3C7.0C21C731 Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable <html xmlns:o=3D"urn:schemas-microsoft-com:office:office" = xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns=3D"http://www.w3.org/TR/REC-html40"> <head> <META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Dus-ascii"> <meta name=3DGenerator content=3D"Microsoft Word 11 (filtered medium)"> <style> <!-- /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0in; margin-bottom:.0001pt; font-size:12.0pt; font-family:"Times New Roman";} a:link, span.MsoHyperlink {color:blue; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {color:purple; text-decoration:underline;} span.EmailStyle17 {mso-style-type:personal-compose; font-family:Arial; color:windowtext;} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.25in 1.0in 1.25in;} div.Section1 {page:Section1;} --> </style> </head> <body lang=3DEN-US link=3Dblue vlink=3Dpurple> <div class=3DSection1> <p class=3DMsoNormal><font size=3D2 face=3DArial><span = style=3D'font-size:10.0pt; font-family:Arial'>Hi all,<o:p></o:p></span></font></p> <p class=3DMsoNormal><font size=3D2 face=3DArial><span = style=3D'font-size:10.0pt; font-family:Arial'><o:p> </o:p></span></font></p> <p class=3DMsoNormal><font size=3D2 face=3DArial><span = style=3D'font-size:10.0pt; font-family:Arial'>I just updated to the latest Snort (2.3.0RC2) and = compiled it with the flexresp option.
