Multicast being sent over hardware address of default gateway address instead of ethernet multicast address

Asked 2022-Mar-10 at 14:07

I have this code to send multicast messages to a group. There are no errors while running the program but when I monitor packets in Wireshark the ethernet destination of my packets are of my default gateway instead of something like 01-00-5e-xx-xx-xx

The code:

244.244.244.1 is not a valid multicast address.

Multicast address are in the range of 224.0.0.1 - 239.255.255.255. The address you're sending to is not in that range. So the outgoing MAC address is not a multicast MAC.

Change the destination IP to be in the range of multicast IP addresses and you'll see a proper multicast MAC address.

I have an app (sveltekit) running inside and would like to access it from other devices on my local network.

I can access it normally from the host machine on localhost:3000.

I want to access it somehow from another machine on the local network. Is this possible? Sveltekit cli has --host flag, which outputs the following:

QUESTION

Floating IPs usage on Digital Ocean

Asked 2021-Nov-27 at 00:12

I am looking for a basic thing yet I have not found not even a single good documentation on getting it done.

I want to allocate a floating IP, then associate it to a network interface of a droplet other than eth0. The reason is I want to have the ability to very easily switch from one IP to the other with a programming language.

In a few words, I want to be able to do these two commands and both should provide a different response.

In the cloud (AWS. GCP etc.) ARP is emulated by the virtual network layer, meaning that only IPs assigned to VMs by the cloud platform can be resolved. Most of the L2 failover protocols do break for that reason. Even if ARP worked,the IP allocation process for these IPs (often called “floating IPs”) would not integrate with the virtual network in a standard way, so your OS can't just "grab" the IP using ARP and route the packets to itself.

I have not personally done this on Digital Ocean, but I assume that you can call the cloud's proprietary API to do this functionality if you would like to go this route.

See this link on GCP about floating IPs and their implementation. Hope this is helpful.

Here's an idea that needs to be tested:

Let's say you have Node1(10.1.1.1/24) and Node2(10.1.1.2/24)
Create a loopback interface on both VMs and set the same IP address for both like (10.2.1.1/32)
Start a heartbeat send/receive between them
When NodeA starts it automatically makes an API call to create a route for 10.2.1.1/32 and points to itself with preference 2
When NodeB starts it automatically makes an API call to create a route for 10.2.1.1/32 and points to itself with preference 1
The nodes could monitor each other to withdraw the static routes if the other fails. Ideally you would need a 3rd node to reach quorum and prevent split brain scenarios, but you get the idea right?

Updated windows docker and now it doesn't work outside localhost

Asked 2021-Sep-23 at 10:38

I have been running a media cluster for sometime without any issues. I have everything networked into two different docker networks... the first network just bridges the docker instance to the local machine, the second network is a docker VPN container that I use for the other media services (an earlier version of what I am working on can be found here: https://github.com/Xander-Rudolph/MediaDocker)

The strangest thing happened today though. I ran the docker update for windows and now docker spools up without any errors or issues, however none of the services work outside of the machine running docker. Usually I have a poke through for a couple of the services in my router (namely wordpress/joomla which is on the bridge) and they work outside of my local network, but none of them are working anymore. I was able to confirm its not the DNS A record because I'm able to use the RDP ports I have mapped for my router, and when I test on another machine in the same network, it can't access the services via the internal IP (but it can RDP).

Anyone have any idea what could have changed to break this? I've already updated all my docker images and even rebuilt my VPN container (before I realized its a networking issue). What are some steps I can do to try to troubleshoot what is going wrong in docker to prevent access outside of localhost?

Update

I've been able to rule out the docker update as the root cause... I upgraded docker on my laptop (which was previously running the same version as my desktop) and its not having the same issue... this configuration must be localized to this desktop... No idea what the issue is... Will try a linux VM on the desktop instead of docker for windows...

Update 2

After a lot of screwing around in both a VM and in WSL, I'm still only able to access the docker services from localhost but not a different machine on my network or via the IP on the host machine (perhaps something similar to this: Can't access localhost via IP address). RDP does work so the computer is accessible but the services are not.

I'm not sure if this is a result of a docker networking config or a windows network config (I'm using WSL with docker installed on ubuntu 20.08) but I'm not seeing anything stick out. I'm going to remove the tag for docker windows but this is definitely an issue with networking and I suspect it has something to do with the fact that the containers are running behind a VPN... although I don't know why I would be able to access them on localhost but not the IP on another VM...

Your question: "...What are some steps I can do to try to troubleshoot what is going wrong in docker to prevent access outside of localhost?..."

Troubleshooting help for you, first do you have multiple networking adapters (Ethernet, Wi-Fi, etc.) present on the host. First ensure, the priority of these adapters needs to be configured in correct order so the Windows networking stack can correctly choose gateway routes.

Now, to fix this set your primary internet-connected networking adapter to have the lowest InterfaceMetric value, use can use these Powershell commands from an elevated console:

afaik the dynamic-room component is designed to attach the networked-scene, not update it (since it doesn't handle updates). That's why the dynamic-room example scene does only have a dynamic-room component, and also why the dynamic-room is not working with networked-scene.

I'd throw all the networked-scene attributes to the dynamic-room setup, but it's also possible to make the two work together pretty much like you want it:
