Shawn, I have not seen any replies to your thread about LSO and DSO or “offloading”. I use ethtool to disable offloading on startup. If you haven’t looked into this it may be your issue. These are my settings in /etc/local.d/ethtool_changes.txt ethtool --offload enp5s0 rx off tx off ethtool -K enp5s0 gro off gso off lro off ethtool -G enp5s0 rx 4096 ethtool -K enp5s0 sg off ethtool -G enp5s0 tx 4096 ifconfig enp5s0 promisc ethtool --offload enp6s0 rx off tx off ethtool -K enp6s0 gro off gso off lro off ethtool -G enp6s0 tx 4096 ethtool -G enp6s0 rx 4096 ethtool -K enp6s0 sg off ifconfig enp6s0 promisc Hope this helps… Bill

If anyone could be of assistance it would be very helpful. Currently I am working on a project that Snort++ (3.0.0-a4) is a part of. I’m attempting to run this on a smaller single board PC made my PC Engine. Please see the specs here: - AMD Embedded G series GX-412TC , 1 GHz quad core - 4 GB DDR-1333 - 3x i210AT LAN I have successfully built and installed Snort++ on this system but the trouble I am having is horrible throughput (~20 MBits/sec) on a 100MBits/sec channel. The only modification that I have made to the default configuration is whats needed to run in inline mode. I am using the AFPacket DAQ. Attached to this message is a test through my setup using iPerf and the Snort++ output. I’ve also attached my configuration file for Snort++. All the best, Shawn <iPerf3_Sample1.txt><Snort++_Sample1.txt>------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot_______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://sourceforge.net/mailarchive/forum.php?forum_name=snort-users Please visit http://blog.snort.org to stay current on all the latest Snort news!
