Snort 3.0 is not detecting shell code attacks

[João Pedro via Snort-users <snort-users () lists snort org>]

I'm testing snort 3.0 with Community rules.
Besides triggering alerts from port scans, it is not detecting Buffer 
Overflow attacks (.i.e. made with Metasploit).
Is there a problem with the current rules in Snort 3.0? Should I 
activate/config something else?

Ps: I'm testing Snort from .pcap files
