Hello! I have faced a problem of low speed of files copying during Snort realization in the IPS mode. The file is copied from one computer to another, communication between them is provided through Snort bridge.
what are the specs of the snort bridge? CPU, RAM, NICs being the most important... what we're looking for is a bottleneck... maybe the CPU is in high usage during the file transfer or possibly you have a lot of swap being used... consumer-grade NICs generally rely on the CPU to do the heavy lifting of data moving whereas server-grade NICs do that heavy lifting on their own which leads to faster processing... assuming your snort bridge is a *nix box, what does your resource consumption look like? free -m; echo; top -n 1 -b | head -n 5 -- NOTE: No off-list assistance is given without prior approval. *Please keep mailing list traffic on the list* unless private contact is specifically requested and granted. ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
