I built snort 1.8.1 with the new rules on linux 7.1. I started it and it ran fine for about 12 hours with many alerts. Now it will not alert but very rarely about once every 12 hours. I know there is more activity but for some reason snort does not or will not pick it up. Could it be my hardware. I am running it on an old pentium 100 Mhz box with 40 MB of RAM. Is this hardware grossly inadequate. I have been monitoring the space in RAM that snort is using and it remains around 15 % of the system RAM. I read the FAQ but I am hesistant to remove any of the rules unless absolutely necessary.
Firstly: Does this box have a IPfilter/IPChains/some firewall running on it? If so, check the archives, there's been a lot of discussion about whether or not snort can see packets when on the same machine as the firewall. Secondly: Test snort. Enable the icmp rules, telnet to route-server.cerf.net and ping/trace back to your IP. Sounds about like the same memory usage that I see. 6-7mb. I'm running it on Sparcs and it takes 6-7, with some plugins off.
1. Is my RAM inadequate?
Do you have RAM envy? *giggle* Sorry I couldn't resist.... :) This is a case of "More is Better" if you can dump any more into it, do so.
2. Does my Processor play a bigger role with snort?
It does, but only on higher speed nets.
3. If I need to remove some rules can anyone make any recommendations.
Remove what your're not interested in. :) If you don't care that someone pings you, disable those rules. If you're only running *nix at home, disable any M$ rules.
