   Aroma: Every TCP Proxy Is Detectable with RTT Fingerprinting▲86

   TL;DR explanation (go to https://github.com/Sakura-sx/Aroma?tab=readme-ov-file#tldr-e... if you want the formatted version) This is done by measuring the minimum TCP RTT (client.socket.tcpi_min_rtt) seen and the smoothed TCP RTT (client.socket.tcpi_rtt). I am getting this data by using Fastly Custom VCL, they get this data from the Linux kernel (struct tcp_info -> tcpi_min_rtt and tcpi_rtt). I am using Fastly for the Demo since they have PoPs all around the world and they expose TCP socket data to me. The score is calculated by doing tcpi_min_rtt/tcpi_rtt. It's…

   Test your WireGuard connectivity and see global stats, no client needed▲43

   Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

    I built a tool to use my homelab apps remotely without a full VPN▲5

    Hi HN, I'd like to share a small Go utility I wrote called prxy. The idea was born out of my frustration with accessing my self-hosted services when I'm on the go. I use WireGuard to connect to my homelab, but I really dislike sending all my computer's traffic through my home network — it slows things down and is inconvenient. I wanted proper application-level split-tunneling. A tool I love, wireproxy, got me most of the way there by creating an HTTP proxy from a WireGuard peer. This is perfect for apps that let you configure a proxy. The problem was the other 10%: apps that don't. Think of…
