Hello, I set up Snort 2.9.6.2 on CentOS 7. the setting up is fine. there is not any error. I configure snort to generate a log file in unified2 type.I run snort with Network Intrusion Detection System mode with this command: *snort -dev -h 10.4.0.0/24 <http://10.4.0.0/24> -c /etc/snort/snort.conf -i enp2s0* the console show packets flow through the network. I test my snort by run a port scanning to 2 PCs in the network with Zenmap (Windows version of Nmap). When Zenmap run finish, there is a file in /var/log/snort : *-rwxrwxrwx. 1 snort snort 0 Sep 16 14:04 barnyard2.waldodrwxr-xr-x. 3 snort snort 4096 Sep 7 11:44 enp2s0-rw-------. 1 root root 0 Sep 20 11:30 merged.log.1411187404-rw-------. 1 root root 0 Sep 20 11:30 tcpdump.log.1411187404* as you can see, there are 2 log file but both of them are empty (their size are zero) I don't know why they are empty.
