Introducing PF_RING 8.6: Runtime Filtering and On Demand IDS at 100 Gbit

Posted · Add Comment

This is to announce a new PF_RING release 8.6 !

This stable release introduces a new Runtime component in PF_RING, which adds support for runtime filtering. This allows an external application to push filtering rules (through a Redis queue) while the socket is running, and offload them to the adapter when supported (e.g. on NVIDIA/Mellanox Connect-X adapters). This enables Zeek and Suricata “on-demand” at 100 Gbit as discussed in a previous post.

This release also adds support for Debian 12 and latest 6.x kernel shipped with Ubuntu 22 LTS. Many other improvements are available in this release, please check the full changelog below for the whole list! Enjoy!
