I trying to add #mldv2 ( #ipv6 #multicast ) support into #lwip
According RFC It looks that subscribers should always send report to query from router but I tried this with both Win and Linux an no OS is doing it.

Did I get it wrong?
current lwip with mldv1 seems to be ignoring any queries as well.

Little bit too much work right now, very little focus on my own projects.

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!! 🙂

Btw, we just released v23.08 of our #opensource network OS, Infix, out the door!

@librecast

Uploaded lcrq 0.1.0 to #Debian and patch submitted for #Guix ... in preparation for more #MultiCast awesomeness!

Another great #podcast by Packet Pushers covering #multicast #DNS ( #mDNS ) in #wifi networks - btw don’t use .local for your corporate name space 😏

@timid_fawn @nikita und das ist technisch falsch. Bei cell broadcast wird nur eine Message versendet, und alle Handys nehmen diese an. Andere Übertragungstechnik. Ich habe meine Diplomarbeit über #Multicast geschrieben und über die dadurch möglichen Einsparungen an Bandbreite. Einzel-SMS verursachen viel mehr Traffic als eine Broadcast SMS. Ich glaube nicht, dass die Netze das gebacken kriegen.

If you design an application that relies on network connectivity. Don't just exclusively rely on #NetworkDiscovery #Autoconf / #Broadcast #multicast
Some of the saner people use #NetworkSegmentation #VLAN #Firewall

Dying knowledge Sunday...

If you sent a TCP SYN to an IP #multicast address that a Solaris system happened to be listening on, it would return a SYN/ACK. I never tried to complete the 3-way handshake, but this was just one small example of a real potential problem with interdomain IP multicast deployment. Think #DDoS.

Cisco IOS for it's part in anomalous behavior would respond to a multicast TCP ACK with a RST, but most curiously in it's response would set the source address to group address the ACK was sent to.

I also merged the `join-group GROUP` PR for #mrouted today. Great little feature, and time to for another release of that #multicast #router project as well 😃

Hopefully the end of my #FritzBox #multicast story. #AVM suggested to try the beta firmware, and that seems to have, indeed, fixed the issue.

🥳

Now I just need to reflash all my ESP8266 to use the old multicast address again 😅 (instead of 224.0.0.9 which I used as interim solution).

This Thursday the 19th at 4pm eastern/1pm pacific I will be the guest on Speedify LIVE, the #livestream about #livestreaming!

The stream will be #multicast on all the major platforms, this is the YouTube link: https://lnkd.in/gnnAzHeG

We'll probably chat about being non-traditional streamer: instead of #gaming for me its all #datascience #machinelearning #python and #sql! Maybe we'll talk a bit of #churn #dataanalytics too...

More #FritzBox #multicast . #AVM replied to my support request, asking me kindly to try a factory reset to rule out any issue with the configuration import from the old box.

To my surprise, that helped. To my bigger surprise, it only helped until the moment I set up the #Telekom #VDSL . Once that is connected, new multicast traffic won't work and after a box reboot, no local multicast (except for 224.0.0.0/24 and 239.255.255.250) works.

I hope they won't just dismiss this obscure thing 😬.

The #multicast on #FritzBox saga continues!

Multicast to 224.0.0.0/24 effectively behaves like broadcast. Switches don't IGMP-snoop that one and the FritzBox brutally sends that into all networks irrespective of multicast memberships, and now that I moved all my sensor devices to use 224.0.0.9, I'm constantly flooding all devices with sensor data 😱

Filed a support request with #AVM for the original issue of 239.23.42.1 not working anymore, let's see where that goes.

I'd also like to wish a (also belated) Happy #Audiobook Release Day to OUT THERE: INTO THE QUEER NEW YONDER!!

This is a delightful, #multicast anthology with stories by a group of AMAZING YA authors, teamed up with some spectacular #narrators! It was an utter joy to narrate two of the short stories in the collection. 🙂

Thank you so much to Jesse Bickford and #Blackstone #Audio for thinking of me for this! You are an amazing human.

APNIC invited us to a blog post, following the short paper that Jon Crowcroft and myself had put together on reconsidering multicast in the light of new network technology innovations. You can find a link to the paper in the blog post.

J'ai une question : combien existe-t-il d'adresses IP de groupe #Multicast potentielles dans IP v.6 ?
@onepict

@Ronkjeffries Thank you for the kind words and encouragement. I do think I could get some other network protocols involved in the operation of my doorbell, like maybe #ZWave and/or #bluetooth.

I think, however, that my next project might be to make the temperature in my home dependent on the correct operation of #BGP, #DNS, and IP #multicast.

@atomicpoet I've been wondering for a while now if #ActivityPub could benefit from some kind of #multicast / #broadcast capabiity to reduce the number of connections to make when sending contents around the #Fediverse.

#init7 Der Nerd ISP aus #Winterthur hat einen neuen Blog Artikel online.
In diesem Beitrag werden die Unterschiede zwischgen #broadcast #unicast #multicast #anycast in der #IPTV Welt erläutert.
