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.

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:

[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.

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).

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?
