Sorry, The 4'th instance is just for testing currently. I am considering replacing the Solaris host as the snort system with two linux systems. (I would then use the Solaris box as the Mysql host/Demarc console) vjl Phil Wood wrote:

The first three run on a Fujitsu Prime Power M400, the fourth runs on a linux PC.2 On my Solaris host I have two 100MB cards that run close to 75% utilizationeach. Snort barely even drops a single packet ever from either of these cards.1 My third instance is reading off a Sun Gigabitcard. This interface only peaks periodically at 2% utilization, but I drop hundreds of thousands of packets. I am using libpcap version 7.1, snort 1.8.4 beta 4. The snortLook at the interface stats. On linux you can cat /proc/net/dev and see if the card has any information. I don't know what solaris provides.process that is dropping all of the packets is only running at about 9% CPU utilization. I have tried reducing signatures, and removing output plugins, but nothing helps . Does anyone have any suggestions for me to try? Thanks!I only see 3 instances discussed. what about the fourth. What kind of linux PC do you have?vjl -- V.Jay LaRosa EMC Corporation Systems Administrator 171 South Street (508)435-1000 ext 14957 Hopkinton, MA 01748 (508)497-8082 fax www.emc.com _______________________________________________ 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://www.geocrawler.com/redir-sf.php3?list=snort-users-- Phil Wood, cpw () lanl gov
