>> Where are your rules files? Also, can you include the output from when you start Snort? I wonder if it is not finding your rule files, as your RULE_PATH variables are all at the defaults with a relative directory and you are starting snort from /usr/local/snort/bin. Also, the sf_portscan preprocessor is commented out, so it won't trigger alerts when you run portscans.

>> In snort.conf, set your RULE_PATH, SO_RULE_PATH and PREPROC_RULE_PATH to the directory where you put your rule files. When I set up Snort on my system, I put them in /etc/snort and code this in my snort.conf explicitly.
>> If you still don't get any alerts after this, open one of the pcap files you downloaded from openpacket.org using wireshark. Write a simple rule alerting on the content of the one or more packets from the pcap and put it in your local.rules file. Make sure that local.rules is  properly included in your RULE_PATH.
>> If the above works, comment out the custom rule you've written and try snort on your network. You should be good to go.

For tests I used different scans with nmap (previously switched on portscan alerting in snort.conf) as well as some pcaps from openpackets (https://www.openpacket.org/capture/grab/52 and https://www.openpacket.org/capture/grab/71). Nothing returned alerts, logs etc. Just some SSL alerts, but files are still empty.

To my big suprise, snort is creating unified output files, but they're empty. I was testing using nmap with intense scanning (including both TCP and UDP) as well as LOIC, but all the files have size of zero. When I redirect output to -A console, I can clearly see the packets, also when I cancel snort process, in the summary I can clearly find statistics, but still nothing can be found in the files.
