Dear all, I have a Snort 2.9 box with two sniffing interfaces: 1) eth1 sniff DMZ traffic --> in snort.conf HOME_NET = 172.18.10.0/24 2) eth2 sniff LAN traffic --> in snort.conf HOME_NET = 10.10.0.0/16 Is it better to have two different snort.conf files, for example: snort-eth1.conf snort-eth2.conf and run two snort instanes like these: snort -D -u snort -g snort -c /snort/etc/snort-eth1.conf -i eth1 snort -D -u snort -g snort -c /snort/etc/snort-eth2.conf -i eth2 In this case, what happen if I download rules with oinkmaster, will they apply on both snort-eth1.conf and snort-eth2.conf files ??? Or what is the best way to do I need ??? Really thanks, JeLo
Here is what we do if we applied it to your type setup: 1) Have a master /etc/snort/snort.conf that has everything you want in it except the interface and home net defined. 2) Have a /etc/snort/snort-eth1.conf that looks like this: config interface: eth1 HOME_NET = 172.18.10.0/24 include /etc/snort/snort.conf 3) Have a /etc/snort/snort-eth2.conf that looks like this: config interface: eth2 HOME_NET = 10.10.0.0/16 include /etc/snort/snort.conf This way the snort-eth1.conf and snort-eth2.conf pickup all the changes you make to your master snort.conf. However, you may really want to do a bunch of additional tuning to customize the conf files (and rules they use) to be tuned to each network. If not though, this is a real easy way to just have the few options you need for various instances to be setup. -- Eoin ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ 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
