[…] The DAQ README says that you'll need to recompile the kernel to enable support for divert sockets by placing the following lines in the kernel config: options IPFIREWALL options IPDIVERT
Thanks for the idea Lawrence. I eventually used the loadable kernel modules by adding firewall_enable="YES" in /etc/rc.conf and ipdivert_load="YES" in /boot/loader.conf instead of recompiling the kernel. Your suggestion pointed me in the correct direction.
The DAQ README also shows sample ipfw commands that you can use, e.g. "ipfw add 75 divert 8000 icmp from any to any". Note that 8000 is the default divert port in the IPFW DAQ; if you change it to something else like 5000, you'll need to start Snort with an additional command-line argument: --daq-var port=5000 […]
Can you please refer me to the DAQ README documentation? Snort User Manual 2.9.4 "1.5 Packet Acquisition" (http://manual.snort.org/node7.html) is the closest thing I found and I don't see the "ipfw add…" example you referred Thanks again!
