  1. Как я делал ping и traceroute на iOS без entitlements — и почему это оказалось проще, чем UMP-консент для AdMob

    Я выпустил небольшое iOS-приложение — NetDiag+. Это набор сетевых утилит: ping, traceroute, DNS lookup, whois, LAN-сканер, port scanner, проверка SSL-сертификатов, BGP/ASN lookup, Wi-Fi info и фоновый мониторинг хостов с пушами при падении. Я начинал его как пет-проект для собственных нужд, потому что на iOS приходилось переключаться между четырьмя разными приложениями для базовой диагностики, и в трёх из четырёх была реклама. Хочу поделиться тем, что мне самому хотелось бы прочитать в начале — почему некоторые вещи на iOS работают не так, как ожидаешь от Unix-фона, и где грабли лежат не там, где кажется. Сразу спойлер по выводам: самым болезненным оказалось не сетевое программирование, а интеграция UMP-консента для AdMob.

  2. I had the opportunity to talk with Xfinity (Comcast) support this morning.

    I was treated to an upsell. Sure, it costs nothing for the first year, but then what does it cost? It is an upsell pure and simple. She said "you can cancel any time." I replied "You can cancel it now." :derpface:

    I was also treated to technical nonsense. The problem (which I still cannot say has been fixed) has to do with bridging and port forwarding. She asked for the name of my Wi-Fi network, which has nothing to do with these issues.

    She should have realized she was talking to someone who knows something about networking when I sent her a traceroute output.

    Screenshot of the upsell below.

    And they wonder why they are so hated... :holdthepain:

  3. [Перевод] Как написать собственную версию Traceroute

    Я никогда не понимал, как именно traceroute обнаруживает каждый сетевой переход. Оказывается, всё дело в хитром трюке с TTL и примерно в 80 строках на Rust.

  6. Ah yes, another *riveting* 3524-word #manifesto on the *thrilling* world of #Tailscale #exit #nodes, because we all needed a 17-minute dissertation on #traceroute evidence. 🙄 Next time, maybe just say "I fiddled with my internet" and call it a day. 🚀

  8. crazytrace, my network simulation program that generates a crazy topology behind a TAP device to test traceroute implementations, now has an apparmor profile.

    Furthermore, I have now implemented capability dropping with libcap-ng, landlock sandboxing (via a blacklist), and seccomp sandboxing (via a blacklist).

  9. Реальность в белоснежных списках

    В условиях изменяющейся сетевой инфраструктуры пользователи мобильного интернета сталкиваются с вопросами: какие ресурсы остаются доступными, и как это выглядит на техническом уровне? Этот материал — результат практического исследования с использованием стандартных инструментов сетевого анализа. Никаких домыслов — только измерения, цифры и технические факты.

  10. 🐢💻 Ah, behold the pure C traceroute! A blazing #fast, dependency-free marvel that’s such a game-changer, it will make your grandma's dial-up look like fiber optics. 🚀✨ Who knew the world was clamoring for yet another #traceroute implementation when we already had approximately 5,287 of them? 🙄🔧

  12. Something strange is happenin, when I try to connect to my #VPS. First of all, I can't connect at all, but the provider tells me, it's working fine.

    I can't #ping it, can't #ssh to it. When I run #traceroute, I get a few hops through my belgian ISP Proximus, then a few on a french hosting company called Colt and after that a seemingly endless line of hops that return no information, that is traceroute displays "* * *"

    Any ideas? Is my ISP preventing me from reaching my VPS?

    🔴 El comando dig permite realizar consultas DNS, no ICMP.

    🔴 El comando tracert es la implementación de Windows de #traceroute, y hace uso de ICMP (entre otros) para encontrar la ruta que toma un paquete hasta llegar a destino en la red.

    🔴 El comando netstat (obsoleto [1]) permite analizar sockets y conexiones.

    Cualquier duda me comentan! Espero que hayamos aprendido un poquito más de #GNU #Linux hoy! ✨ 😃

  15. Hey #OpenWRT, I can't access sysupgrade.openwrt.org.
    Ping, and ICMP #Traceroute return within 100ms, but HTTP traffic isn't getting through: gist.github.com/AliveDevil/6a6

    Anyone got insights here? ISP is #Telekom.

  18. #TIL about the `namei` tool which is sort of like #traceroute but for filesystem traversal.

    This is especially useful on #nixos where you're frequently dealing with stuff that is multiple levels of symlinks deep.

    It's probably already on your system because it's part of #utillinux; go try it out:

    namei `which ls`

    #namei #symlink #linux

  20. CW: pondering about strange routing of internet traffic
    Edit for folks not reading the thread. Looks like badly configured reverse dns; that IP actually has multiple domains associated with it, all of them wrong.
    So you know somethings badly messed up when #traceroute shows lots of my traffic going through ftp.clarins.ca. Why does #Clarins, the makeup and skincare brand, have an FTP server? What do they do with it? Why is it routing traffic for The National Research Council (nrc.ca) and other #Canadian government websites? I have many questions. #networking #canada

  29. I've been using #Pingplotter for a while on #macos, and am on my way to #Linux . Are there #foss alternatives that would allow me to #ping or #traceroute some hosts, and log an alert when destination can't be reached or when TTL gets too long?

  30. Some time ago I asked myself what happens if I have a case with traceroute where a response comes from two different addresses. I then develop crazytrace. The project is available on CodeBerg under the GPL3: codeberg.org/mark22k/crazytrac Today I also tried to roll out the project on reseau.mk16.de (CRXN) and it worked!
