You do realize with that configuration, you have created a gateway to each network? The performance thing is based on traffic and load. If you have dual T-3's, 500 servers and 10,000 internal clients, I don't think that box can keep up. Jason Lewis http://www.packetnexus.com It's not secure "Because they told me it was secure". The people at the other end of the link know less about security than you do. And that's scary. -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net]On Behalf Of Joseph Nicholas Yarbrough Sent: Tuesday, June 19, 2001 9:01 AM To: snort-users () lists sourceforge net Subject: [Snort-users] advice on scaling / performance I have a question concerning performance. I searched the archives and wonder if this info is up to date. As base information, we will use 99% of the snort.org ruleset. Our original idea was 4 network cards with a cable running from each to an important part of the network (inside & outside firewall, service net, and some side network). We would be running a single instance of Snort running on each interface. Comments or suggestion? How powerfull of a system should we use to be able to process all this data (at full loads if needed) on a 100mbps network? Everyone seemed very sure that I should use "high quality" cards with "good" driver support for your platform. I have been unable to find a network performance review for Linux (our target platform). I have gathered from newsgroups, which are known for spreading complete garbage, that I should use Intel cards and not use 3com cards on Linux. Anyone have a clue? Perhaps a link to a review? I planned a rackmount system with: Intel Pentium III 850mhz (256k cache) Intel eepro100 NIC 128MB sdram 20GB ATA/100 card Mandrake Linux (perhaps 7.1?) Which kernel version should I use? I would like to have 2.4 for netfilter, but should I use 2.2 for some reason? Would it be a better idea to build a smaller box for each interface we want to monitor? Feel free to ignore any stupid questions, and only answer questions you have time for. I don't want to chew up everyone's time with my constant badgering.
