This is ACID doing the DNS lookup, not snort. You can fix this by editing the acid_conf.php file and changing to this value: resolve_IP = 0; Other tweaks: 1) show_summary_stats = 0; # This will disable showing stats at the top 2) event_cache_auto_update = 0; # Huge performance boost but you will have to manually update your cache 3) main_page_detail = 0; # Has to do with summary stats 4) show_previous_alert = 0; # Will only show first/last alert Also, if you regularly delete data from ACID you should optimize your database. When I used ACID I use to have this run from cron once a week: for table in `echo show tables | mysql <name_of_snort_db> | tail +2` do echo optimize table $table | mysql <name_of_snort_db> done This requires the root user to have access to the db without a password from localhost. If the root user does not have this access you can specify one that does with -u <user_name> after the dbname. Or if you need a password you can do a -u <user_name> --password=<password>.

Hi When I run Acid.. it takes a lot of time to show up.. I'm guessing its because of the excessive number of alerts I am receiving. Inorder for me to improve the speed ... in a little way... is there any way in snort where I can remove its capability of trying to look up the DNS to try to resolve the ip addresses it catches in the alert files. My thinking is that by stopping this function in snort... Acid wont have that "FQDN" column that always shows me Unable to resolve address... thus improving the speed. Please could someone correct me if I am wrong... or let me know how to remove the DNS lookup in snort. Thanks Clayton __________________________________ Do you Yahoo!? New and Improved Yahoo!
