Hi all I have had snort distributed over 6 servers and about 30 interfaces for a few years now. We recently upgraded to 2.9.3 and I’m still trying to get barnyard2 to work with the logging to mysql. Now I’ve read of a few people who have issues when using snort on several interfaces, that the output is logged to pcap and not to unified2, which is what also happens here. Snort.conf is configured to log to unified2 (and syslog, but that part works fine): output unified2: filename snort.u2, limit 128 output alert_syslog: LOG_LOCAL7 LOG_WARNING LOG_NDELAY the file is written but in pcap and not u2. (error when trying to read it with u2spewfoo), it’s started up with the following attributes: snort 9485 1 0 09:41 ? 00:00:16 /usr/sbin/snort -s -D -i eth1 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth1 snort 9495 1 0 09:41 ? 00:00:00 /usr/sbin/snort -s -D -i eth2 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth2 root@sensor:/var/log/snort/eth1# tcpdump -r snort.log.1359535265 reading from file snort.log.1359535265, link-type EN10MB (Ethernet) 10:02:15.777196 IP 1.1.1.1 > 2.2.2.2: ICMP echo request, id 1, seq 25, length 40 10:02:16.777892 IP 1.1.1.1 > 2.2.2.2: ICMP echo request, id 1, seq 26, length 40 10:02:17.776212 IP 1.1.1.1 > 2.2.2.2: ICMP echo request, id 1, seq 27, length 40 10:02:18.774413 IP 1.1.1.1 > 2.2.2.2: ICMP echo request, id 1, seq 28, length 40 Can someone point me to why this problem occurs and how to fix it? Google didn’t help me yet and I couldn’t find the solution in old mailing list entries. Thank you -des
Hi Désirée, It looks like the '-s' on the command line is overriding the logging options you have in snort.conf and the '-l' on the command line is causing Snort to log to the pcap default. Since you already have a line for syslog output in your snort.conf, you should be able to remove the '-s' on the command line and logging to both unified2 and syslog should work as expected.
