#traceroute — Public Fediverse posts

Deep-dive into firewall behavior with a UDP scan combining service detection and traceroute. Using #nmap -sU -sV --traceroute --version-intensity 7 on ports 53, 123, 161, 500, it maps network paths and probes ICMP unreachable responses. Requires root/sudo on Linux/macOS. #snippet #udp #traceroute #ValtersIT

Boss: Bro, so have you traced where the problem at the network from?
Bro: Not yet sir.
Boss: Have you tried using traceroute?
Bro: I did, but...
Boss: 😭

🚀🎨 So, you decided to play Picasso with #traceroute, turning network diagnostics into avant-garde art? 🤔 Because who wouldn't want to express themselves through ICMP packets? 🙄 Next up: Mona Lisa in binary, because why not? 😂

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.

[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.

🎉 Behold, the groundbreaking revelation: Traceroute's "mysteries" #unveiled by a Rust evangelist who never bothered to Google! 🚀 Brace yourselves, folks, for the earth-shattering news that 80 lines of code can decipher the magical #TTL sorcery—truly deserving of a #LinkedIn mention. 📚✨

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. 🚀

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).

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.

🐢💻 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? 🙄🔧

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.

Our Neo Network Utility gives you a full range of network tools, all from a nice, native Mac app. Version 1.1.2 adds autoscrolling for the Ping and Traceroute tools, improves model and vendor detection, and enhances the handling of the network adapter selection. All for free. #neonetworkutility #networkutility #network #ping #traceroute #pressrelease

This amazing, cursed, fun, terrifying, makes you sick if you've ever worked in #networking and incredibly entertaining all at the same time:

#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

New blog post: How are the metrics (average, jitter, standard deviation, ...) calculated in mtr?

Backwards compatibility is (useful and) annoying ... lower-case XML tags look nice.
