Dear All, I'm trying to run snort 3 in multi threaded mode. As i only appear to have a single thread with maxes out at 100% cpu utilisation, when other cores in the servers are not utilised. I am running using NFQUEUE as i also have a firewall on the same router. I added -z 4 to the command i use. /usr/local/bin/snort -c /usr/local/etc/snort/snort.lua -s 65535 -k none -l /var/log/snort -D -m 0x1b -Q -z 4 Although snort launches i get the following errors, and snort while working does not run in multithreaded mode. nfq DAQ configured to inline. initializing daemon mode child process is 39280 Commencing packet processing # ++ [0] 0 ++ [1] 0 ++ [2] 0 ++ [3] 0 Error receiving message from the DAQ instance: nfq_daq_msg_receive: Netlink message processing failed: -1 - Operation not permitted (1) -- [1] 0 Error receiving message from the DAQ instance: nfq_daq_msg_receive: Netlink message processing failed: -1 - Operation not permitted (1) Error receiving message from the DAQ instance: nfq_daq_msg_receive: Netlink message processing failed: -1 - Operation not permitted (1) -- [3] 0 -- [2] 0 Is it possible to run snort 3 in multi threaded mode with NFQUEUE. Have i made some type of config error Many Thanks _______________________________________________ Snort-users mailing list [email protected] Go to this URL to change user options or unsubscribe: https://lists.snort.org/mailman/listinfo/snort-users To unsubscribe, send an email to: [email protected] Please visit http://blog.snort.org to stay current on all the latest Snort news!
