Finally getting around to trying to learn #Wireshark and understand some of the network stuff a little more.
One of the first things I noticed which seems kind if odd to me is that periodically I see a slew of #ICMP ping requests to my laptop IP from source addresses that are external to my network.
Is this normal? What external IPs should I be expecting to send ping requests to my laptop on my home network?

Wozu an Protokoll-Standards halten, wenn man auch sein eigenes Süppchen kochen kann?
DSCP? Unwichtig! ECN? Zurücksetzen auf 0! Don't Fragment gesetzt? Jetzt nicht mehr! ICMP ID und Payload? Zufall!
Und dann tagelang debuggen, warum Traffic links und rechts vom Gateway unterschiedlich aussieht :')

I'm trying to setup wireguard, but as a first step, I can't seem to get a simple ping to work, not even to the normal ip address. I'm guessing it's a firewall thing, I've already set `pass inet proto icmp all icmp-type $icmp_types keep state` but no luck.. (pf on FreeBSD)
Giving up for today 😅

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.

Немного извращений из мира прокси и VPN
XTLS-Reality, XHTTP, Naiveproxy и всякие там AnyTLS - это не интересно. Давайте копнем чуть глубже и посмотрим, где прячется настоящее безумие. Особенно учитывая, что мы живем во времена, когда даже самые, казалось бы, безумные вещи, могут оказаться весьма полезными чтобы не сойти с ума.

Sending ICMP Packets with Python Socket: Adventure in Signaling
In this article, I demonstrate how to craft and send ICMP packets using Python raw sockets, covering packet structure, checksum calculation, and low-level network communication.

Who do you usually ping?
…when you need to spontaneously check if you can see the WAN from the #cmdLine of a system.
For me it's usually ping cnn.com.
I guess it was cuz it is short and quick. I've been using that for at least 28yrs. Just tradition now. I hope they don't stop responding to ICMP requests. lol

Omar Ashour and I are now live-streaming Monday morning around 10:00am-ish MDT. Will we always be live? Not sure, but for now we are having a good time. Come join us if you can.
Our last live-stream we started writing a C program to send a ping. Why? Because Omar Ashour wanted to learn more about low-level networking. Spoiler: we didn't complete the app but we do have a good discussion of hex, binary math, and bit shifting in-between the over two hours of fumble around C.

Have a question you want answered in a future video? A challenging or interesting problem you want to see solved? Constructive feedback? Then comment, DM, or send an email to [email protected].
Thanks for watching!
