Well, I used the command: sudo /usr/local/snort/bin/snort -b -k none -u snort -g snort -c /usr/local/snort/etc/snort.conf -i eth1 And when I looked at the /var/log/snort directory again, it shows that the log files are still blank: drwxr-xrwx 18 root root 4096 Mei 27 14:17 .. -rw------- 1 snort snort 0 Mei 27 14:18 tcpdump.log.1401171492 -rw------- 1 snort snort 0 Mei 27 14:18 snort.u2.1401171492 -rw------- 1 snort snort 0 Mei 27 14:18 snort.log -rw------- 1 snort snort 0 Mei 27 14:49 snort.alert drwxr-xrwx 2 snort snort 4096 Mei 27 14:51 .

If you want that your output directive work make sure that you do not the the -b command line switch and also -A full is the default you can skip that. Also make sure that you do not have checksum error on the interface your monitoring, you can add -k none to your snort command line argument to disable checksum validation to check if it can help. -elz On Mon, May 26, 2014 at 5:54 AM, Hadri Rahman <hadri90 () gmail com> wrote:Snort could log attack but logfile remains empty. I've set up Snort and Barnyard2 on my system using this guide:http://www.symmetrixtech.com/articles/016-snortinstallguide2953.pdfI then added: ifconfig eth1 up /usr/local/snort/bin/snort -D -u snort -g snort \ -c /usr/local/snort/etc/snort.conf -i eth1 /usr/local/bin/barnyard2 -c /usr/local/snort/etc/barnyard2.conf \ -d /var/log/snort \ -f snort.u2 \ -w /var/log/snort/barnyard2.waldo \ -D In my /etc/rc.local file. It was able to detect the attacks I've performed, but when I checked the logfile, the logfile remained empty. I've also tried the commands: sudo /usr/local/snort/bin/snort -A full -u snort -g snort \ -c /usr/local/snort/etc/snort.conf -i eth1 and sudo /usr/local/snort/bin/snort -dev -l /var/log/snort -b -u snort -gsnort-c /usr/local/snort/etc/snort.conf -i eth1 But the results remained the same, but the second command would usually result in something like this appearing on the screen: 05/22-10:49:13.435375 00:26:18:8B:75:8C -> FF:FF:FF:FF:FF:FF type:0x800 len:0x5C 192.168.2.1:137 -> 192.168.2.127:137 UDP TTL:128 TOS:0x0 ID:1389IpLen:20DgmLen:78 Len: 50 E2 2B 01 10 00 01 00 00 00 00 00 00 20 45 42 46 .+..........
