Thanks, that's a decent video, but... it leaves out the most important part for me...  It says that F2B will "ban the IP" when needed, but exactly *HOW* does it do that?  As far as I know, it adds something to the iptables data which actually does the blocking of an IP.  That's great if your system is running iptables (to support a firewall app).  I think Ubuntu and similar run something called "UFW" for this purpose, but I am not running anything like that.

No, using Slackware here.  No firewall running on the local machine, because it's behind a router anyway.

Thanks for the video anyway.  If you saw one of Digital Man's messages to me, he has provided some new functionality to auto-ban IP addresses based on exceeding thresholds for too many concurrent connections.  I have updated to the latest SBBS version to get that, and it is definitely working/helping.  Worth getting for anyone reading this...  ;-)
