Hi, I have installed a snort sensor on a Pentium III 733MHz to monitor 3
C class traffic, but I see everytime cpu usage 100% is it possible? 
On this machine I have two processor but snort use only one processor,
is there any way to use two processor?

To get snort to use 2 cpus, you have to run 2 instances of snort.  It
is not multithreaded.

You might try running 2 class Cs on one snort instance and 1 on the
other and see how it goes.

How much traffic are you seeing?  What is the rough breakdown between
ports/protocols?
