Basic snort setup for processing pcap produces no alerts

[Egon Kidmose <kidmose () gmail com>]

Hi all,

I am working with snort for the first time, trying to feed in a pcap with
known bad traffic and hoping to get out a list of alerts.

I use snortrules-snapshot-2960.tar.gz from
http://snort.org/snort-rules/without pulledpork as I don't need to get
updates.
My pcap contains a trace from a controlled environment where I have
infected and remote controlled a machine with the fairly old irc bot sdbot,
so I expect some reaction from snort, however I get none.

My thought is that the absence of alerts follows from one of the following:
a) incorrect configuration
b) my trace not being "bad enough" for snort to pick it up
c) or something else...

Is there anyone out there who can help me to fix the configuration, point
me to some reference trace that certainly triggers an alert or simply
provide possibly useful hints/suggestions/insights?
Anything would be greatly appreciated!
