From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hmm I keep hearing about it but haven't looked into it. One thing I have set up between my systems if they share the blocked IPs with each other so every server drops a blocked address at the same time... I assume crowdsec has something similar for local sharing so I don't have to wait for a blocked IP to be sent to them, added to the database, and sent back to my local machines again?
One way to do this would be set up crowdsec bouncers on each server but only run a single instance of the crowdsec daemon. Send all logs to the daemon and let it communicate with all the bouncers.
Cool, thanks for the tip!
