It's a great tool for sure. I've tried to find approach to patch naughty IPv4 only apps with my own LD_PRELOAD library and during research phase I found tnat64 and it worked exactly as I expected.

Thank you for raising this question. Well, for my things I use MongoDB because of very convenient integration with programming languages (Go, C++ via Mongo C++) and zero hassle with schema But I'll be happy to replace it by something e

Thank you for great question! Unfortunately, false positive alerts are pretty common problem. FastNetMon is threshold / baseline based DDoS detection engine and it requires pretty careful baseline calculation. Typically, we recommend e

If you Like XDP you may check AF_XDP! It's like PCAP but EXTREMELY fast! It require kernel 4.18+ and you can use my guide to build test application very fast: https://github.com/pavel-odintsov/fastnetmon/wiki&

I had very bad experience with physical server at online.net. One time I noticed that my server did not return from reboot. I logged into KVM and discovered that both my SSD drives failed and need replacement. I immediately backed up all my

After short conversation with GoBGP project they re-lcienses this file in BSD terms: https://github.com/osrg/gobgp/issues/1384 We will update proto file to this version in FastNetMon soon! :)

You could read my blog post about it instead: https://translate.google.com/translate?hl=en&sl=ru&tl=en&u=h... It's in russian but Google trsnalate crashes language baarriers! :)

Probably, we went away from the topic. Feel free to raise PR if you want to have DOTS in FastNetMon. We'll review it carefully and if it fits our design guidance we will accept it. Thanks :)

This message was prepared about 14 months ago and shared privately with WG members. So, at least few persons from this WG saw it.

I think that we do not have Apache licensed code in project, it's just protocol description for protobuf: https://github.com/pavel-odintsov/fastnetmon/blob/2005b4e94e... And it's not used by version

I tried to play with slightly similar idea previously: https://github.com/FastVPSEestiOu/Antidoto but decided to keep my eyes on DDoS mitigation only.

Also, we sent a number of ideas/suggestions to DOTS. And I do not think that our feedback was taken into consideration.

It's slightly different thing. For our install script we have this short introduction: https://github.com/pavel-odintsov/fastnetmon/blob/master/doc... I think we definitely need some guide for Quick

FastNetMon does not implement DOTS yet. Instead, we support API for scrubbing centres/boxes directly.
