We can detect hosts in our networks sending or receiving large volumes of packets/bytes/flows per second. We can call an external script to notify you, switch off a server, or blackhole the client.<p>…<p>Why did we write this? Because we can't find any software for solving this problem in the open source world!<p>What is a "flow" in FastNetMon terms? It's one or multiple UDP, TCP, or ICMP connections with unique src IP, dst IP, src port, dst port, and protocol."
And if you're on a FreeBSD box, just pkg install fastnetmon<p>Glad to see this software exists. Had to help build a poor man's version of it at a previous job and it was half baked due to lack of time.
Is there any documentation how to set this up fast and reliably on an existing Debian server? The only thing I could find was this:

Hi. I have a doubt regarding the license[0].<p>Aren't GPLv2 and Apache v2 licenses incompatible. How can they co-exist in the same project? (The copyright file says GPLv2, or is it GPLv2+?)<p>[0] <a href="http://metadata.ftp-master.debian.org/changelogs/main/f/fastnetmon/fastnetmon_1.1.3+dfsg-1_copyright" rel="nofollow">http://metadata.ftp-master.debian.org/changelogs/main/f/fast...</a>
I wonder if <a href="https://fastnetmon.com/" rel="nofollow">https://fastnetmon.com/</a> and DOTS [1] are roughly the same thing?<p>[1] <a href="https://datatracker.ietf.org/wg/dots/about/" rel="nofollow">https://datatracker.ietf.org/wg/dots/about/</a>
What's generally the state of the art in open source home/small office network monitoring? I would like to know and query/audit communication patterns of my devices. While maintaining privacy -> no cloud based commercial products.
