#multicast — Public Fediverse posts

It's interesting how ass Windows is to use when it comes to low level networking. Nothing works as expected or how it works elsewhere.

In this case I'm trying to stream audio to a multicast address. Sure, the audio arrives, but it arrives in clumps every 300-1000 ms, not as a, well, smooth stream. Cue and endless search to try to find some option that would work around the idiotic Windows kernel's ideas. Still searching and hating this utter shit.

they think they found the issue.

here is their reply:

"The Problem: In many Qualcomm-based (QCA) drivers, the Multicast Snooping (MCS) module is programmed to ignore "well-known" or "permanent" multicast addresses (reserved by IANA) for snooping purposes. It floods them to all ports to ensure compatibility with network protocols that rely on these addresses. Like the one that you are choosing here is just the permanent multicast address "ff05::1234".

The Consequence: Because the system doesn't "snoop" these addresses, it never learns which specific client wants the traffic. Without this "MDB" entry, the Access Point cannot perform Multicast-to-Unicast (M2U) conversion, which is essential for stable video/data streaming over Wi-Fi.

The Solution: Moving to the ff3x::/16 range (often used for SSM - Source-Specific Multicast) or other non-permanent ranges allows the MCS to intercept the join requests and create the necessary entries for optimization."

I then tried ff35::1234 and it did not work #IPv6 #multicast #cursed

I have developed mping-sender over the last few days. It is a simple program that sends a UDP packet to a (freely selectable) multicast address every second. It is therefore well suited for testing multicast. It is partially compatible with the mping client.

Furthermore, it is protected by landlock, seccomp, libcap-ng, AppArmor, and systemd.

Anyone know why #UPnP appears to be broken on #NixOS?

So far I only found one forum post attributing it to a "beyond repair" broken Multicast in #NixOS

#Multicast

After two weeks of off-and-on banging my head against this multicast routing lab, I finally found the problem. The default TTL for •all• multicast packets on Linux is… 1. Of course, I overlooked all of the simple stuff in my troubleshooting, as one does. #NetEng #Multicast #Troubleshooting #LessonLearned #ThereAreDays #Sigh

I haven’t played extensively with multicast routing for a little over a decade, but here I am grinding the rust off of the metal. Gotta stay fresh if I want to engage in silly proof-of-concept labs. #NetEng #Multicast #Labbing #WorthIt

aReal Intelligence: emergent creative dynamics in an AI network

Olivier Auber
Center Leo Apostel for Interdisciplinary Studies (VUB)
Presentation at the Art and Creation seminar, Institut ACTE, Paris 1 Panthéon Sorbonne, February 6, 2025.

During this session, we presented and discussed the foundations of interdisciplinary research examining the emergence of autonomous realities within a network of LLM-type artificial agents deployed in a collective gaming environment. The chosen test environment is the Poietic Generator (PG), a real-time collective graphic game conceived in 1986, known as an emblematic net art work and precursor to current "social networks". The PG exists in both distributed (#Multicast protocol) and centralized (#Unicast protocol) versions. The Unicast version is open free of charge 24/7 to all human internet users, excluding robots. It is regularly used by individuals and professional, associative, school, or university groups interested in collective phenomena from all continents.

Anyone else having trouble with Nanoleafs in Home Assistant?

Having two Nanoleafs: 1 Hexagon Shapes and 1 Lines. Since a couple of weeks (obviously I dont know what (I) changed... I would say: nothing 🤣), they dont work anymore via Home Assistant (and their own App).

My Access Point still says, they are connected via wifi without any trouble. ICMP Echo Requesting them, works fine (dont know which service I could check).

Thing is, out of the sudden, Home Assistant thinks, they are reachable via IPv6 (some ULA Address, not my IPv6 and that Subnet even doesnt have IPv6).

That Home Assistant Issue pointed me to mDNS: https://github.com/home-assistant/core/issues/131643

Home Assistant seems to use https://github.com/milanmeu/aionanoleaf library which doesnt correctly parse IPv6/Port things.

Im wondering, if anyone else having some strange behavior with Nanoleaf and mDNS in their network?

Just trying to figure out whats going on and it doesnt look like its only a bad library in Home Assistant (there is definitely a Bug in parsing IPv6 addresses) but some Nanoleaf Network Issues. As I mentioned: Nanoleafs sometimes doesnt report their IPv4 Address via mDNS - but still are reachble via ICMP.

Обнаружение устройств через UPnP / SSDP

Что больше всего бесит при первом запуске устройств с управлением по Ethernet? Необходимость его искать в сети с использованием зоопарка из подходов. Тут используются программы автопоиска (например Winbox для MikroTik), дефолтные IP адреса (все эти 192.168.1.1, 192.168.100.1, 192.168.2.1 - кто во что горазд). Иногда надо со смартфона показывать QR коды в камеру устройства или передавать настройки тональными сигналами в микрофон. Мы задались целью найти стандарт для поиска устройств в сети и внедрить его в свои устройства на основе микроконтроллеров и/или одноплатных компьютеров. Это статья о стандартах, их особенностях, преодолённых трудностях и об открытом коде, который мы написали для себя и считаем лучшей в мире открытой реализацией SSDP сервера и клиента.

Added basic #multicast functionality to #sysklogd today. And then my regression tests suddenly started failing … on CI. Obviously work fine when run locally, and tests failing that are not related to the latest changes and worked fine the last weeks *sigh*

At least I know what I’ll be doing tomorrow.

Amazon VPC 的 Multicast 支援

看到「AWS Elemental MediaConnect Gateway now supports source-specific multicast」這篇的時候在想什麼時候 AWS 有支援 Multicast 了，翻了一下是 2020 年的事情：「Integrating external multicast services with AWS」，而且看起來當年推出的時候還沒把 IGMPv2 放進去，過了幾個月才更新：

@T_X @troglobit I did find that link, but I don't think I understand #multicast or the #socat syntax enough to follow it.

It would probably help a lot if I read more than the green parts (see otherwise-unrelated #ADHD toots)

If you would be so helpful as to even just assure me my solution is on that page it would be very helpful. I could stop bouncing around google and just focus on pulling the solution out of the wall of text

#it #networking gurus!

I have a number of real-time systems that #multicast data. I want to forward that mcast data from one machine to another on the same physical network but a different mcast address (I guess...?)

It looks like #ncat, #socat and maybe even #ssh could do this but I can't figure out how to do it with multicast specifically

Fact checking IPv6: on a switch without MLD snooping, all ICMPv6 multicast packets (neighbor discovery, router discovery/advertisements and so on) are sent to all ports of the switch; they are thus visible in promiscuous mode by all nodes connected to the switch. And that means that multicast in this case is not more efficient than broadcasts from the network load point of view. Or am I missing something ?

Hallo #fediverse (for english text pls read answer)!

In einem anderen toot (oder trööt?) heute hatte ich es bereits thematisiert: #Zeit🕛! Oder besser gesagt, die fehlende Zeit⏳. Vielen der mir Folgenden oder denen ich folge würde ich gerne persönlich einen guten Morgen, einen guten Tag und auch eine gute Nacht wünschen. Oder auch einfach eine gute Zeit. Sozusagen per #Unicast🤝 oder #Multicast👥👥.

Und dann gibt es doch so viel zu lesen, sich einzubringen, seinen 'Senf' dazu zu geben. Manchmal lässt sich das ja sogar mit einem freundlichen Gruß 💚 verbinden. Wenn man dann auch noch eigenen '#Content' produziert, schmilzt die verfügbare Zeit noch weiter zusammen.

So bleibt mir oft nur noch der #Broadcast🌐, der nicht näher adressierte oder personifizierte #Rundspruch an alle , die mir zuhören, lesen und zuschauen, wie ich die Welt in meinen #Fotos sehe.

Der ist aber deshalb nicht weniger herzlich❤️! Und nur der Zeit geschuldet. Oder besser gesagt, der fehlenden⌛ Zeit.

Daher wünsche ich jetzt ALLEN einen schönen Tag, eine gute, eine friedliche Zeit. Und schöne #Weihnachten🎄, wer es feiert, wo auch immer auf der #Welt 🌐!

PS: Das Foto im trööt darf gerne genutzt werden, um liebe Wünsche oder Lebensweisheiten zu versenden 🎁 Sundown © 2023 by B59R is marked with CC0 1.0

But at least the new job is still great! Get to talk about #NETCONF #ospf #multicast #linux and #embedded all day long, so I'm a happy camper!! 🙂
