Hello, I installed Snort-1.7 RPM in my Redhat Linux 6.0. However, I couldn't use the rule options "resp" and "react", which need FlexResp. When I run Snort it says, ERROR: /etc/snort/test.conf (5) => Unknown keyword "resp" in rule! How can I enable FlexResp with Snort RPM package? Or should I use the source code file (.tar.gz) ?
