Hi Tony, Thank you for replying and showing me your config. I'm monitoring a 20Gb (10Gb each direction) link, so my plan is to load-balance (with pf_ring) that considerable traffic volume across the 16 snort instances with one config file. I haven't got to barnyard installed yet, that'll be next if I get this bit working! J. On 4 December 2015 at 16:10, Tony Reusser <treusser () filertel com> wrote:
James, I am only running two simultaneous instances of snort. One snort server with two sniffing interfaces on two separate network segments. The way I am doing it, I have a separate snort.conf file for each “sensor” and each has its own output file for barnyard (two instances of barnyard with two config files running also) and each has its own log file. Not as complex as your deployment, but here’s how my startup looks: /usr/local/bin/snort -dD -c /etc/snort/snort_eth1.conf -i eth1 /usr/local/bin/snort -dD -c /etc/snort/snort_eth2.conf -i eth2 # # /usr/local/bin/barnyard2 -D -f snort_eth1.u2 -d /var/log/snort/eth1_logs -c /etc/snort/barnyard2_eth1.conf /usr/local/bin/barnyard2 -D -f snort_eth2.u2 -d /var/log/snort/eth2_logs -c /etc/snort/barnyard2_eth2.conf Hope this helps. -tkr *From:* James [mailto:snort () cyclohexane net] *Sent:* Friday, December 04, 2015 8:54 AM *To:* snort-users () lists sourceforge net *Subject:* [Snort-users] starting multiple instances of snort Hi, I'm attempting to start 16 instances of snort using a for loop, but see this error repeating in /var/log/messages and hope someone can help as I'm drawing a blank at the moment. snort[8537]: FATAL ERROR: Stat check on log dir failed: No such file or directory.
