Re: Rules not hit on 2.9.1.1 sensor

You will need a full pcap to reproduce the issue correctly.  The
tcpdump.log will only have the packet the alert hit on, not the full
stream.  Use something like daemonlogger, sancp, or ipaudit to do full
pcap, which you should really do anyway.

The same happens on 2.9.1.1 when using a pcap readfile?

I've tried with the following:

snort -c /etc/snort/pcap.conf -r tcpdump.log -A console -q

'pcap.conf' is similar to my snort.conf but with afpacket DAQ
commented out and only including one ruleset.

However this doesn't work on my 2.8.6 box either with a tcpdump.log
generated from the actual alert so I'm obviously using the -r option
incorrectly!
