    The majority of the Internet’s routing and switching architecture is BSD based. Historically it had the most stable and performant network stack of all the OSs.

    I used it extensively at one job in a previous life when I was a network appliance developer. It was rock solid and lightning fast. Tried it as a desktop at home and had a terrible experience.

    The little differences in the Unix commands used to drive me nuts as well…










  • Sounds like you were out of resources. That is the goal of a DoS attack, but you’d need connection logs to detect if that was the case.

    DDoS attacks are very tricky to defend. (Source: I work in DDoS defence). There’s two sections to defense, detection and mitigation.

    Detection is very easy, just look at packets. A very common DDoS attack uses UDP services to amplify your request to a bigger response, but then spoof your src ip to the target. So large amounts of traffic is likely an attack, out of band udp traffic is likely an attack. And large amount of inband traffic could be an attack.

    Mitigation is trickier. You need something that can handle a massive amount of packet inspection and black holing. That’s done serious hardware. A script kiddie can buy a 20Gbe/1mpps attack with their moms credit card very easily.

    Your defence options are a little limited. If your cloud provider has WAF, use it. You may be able to get rules that block common botnets. Cloudflare is another decent option, they’ll man in the middle your services, and run detection and mitigation on all traffic. They also have a decent WAF.

    Best of luck!
