Hi All,
Multicast is working fine for me with the latest patches in 9front hg on my
raspberry Pi.
Thanks Cinap, Alex et al for pointing me in the right direction.
Current status is that I can use multicast dns to discover nodes on my local
network using a Go library and some patches to the Go
I recompiled with the latest in hg. I'm still not having success with the
multicast. I'm going to start adding debugging to figure out what's going on.

You don't have to do full filtering - it's enough to enable the adapter
to receive all multicast messages and the kernel driver will filter out
the uninteresting on
Thanks Alex, Cinap,
Right, the Pi uses USB for its built in nic.
I wanted to make sure that I have narrowed down where the missing functionality
is. It sounds like I need to have a look at how multicast filtering works with
supported PCI nic cards and apply that to nusb/ether.

Chris,
As cinap says:
nusb/ether doesnt implement multicast filter.

This is your problem. I believe the Raspberry Pi has its NIC attached
via USB internally. Therefore, multicast won't (currently) work on the
Raspberry Pi.

Yes, same here. Both are wired directly to a dumb switch using link local
addresses. No router.
I tried 225.0.0.1 port 1234 on both ends.
I can't figure out what the contents of the buffer is. Just random bytes?
It is weird that the ifc number gets filled in after pinging the multicast
addres

How are you connecting these devices to the network? I use wired
connections to a single (dumb) switch.

These programs work without any setup on 9front. Once the programs are
running I can ping the multicast address from either host and a new route
appears in /net/iprou
Hi Alex,
I tried the mcastsend and mcastrecv on my two raspberry Pi's running 9front.
I'm seeing similar routes as in my own experiment without the interface
number, tagged as 4m for IPv4 multicast. I can ping each device from the other
using their unicast addresses.
Unfortunately, it doesn't
Thank you Alex,
I will give these a try tonight. I'm happy to hear that multicast can work and
it's likely just some silly mistake on my end.

Years ago I've successfully used multicast for a project.
The project has been aborted just after the test of the multicast.
Probably I've that (sparse pieces of) sw ... somewhere.
I remember that I wrote them with no problems following the Plan9 man.
I also remember successfully tests of one2ma

After some investigation and trial and error I'm left with the sense that
multicast is not entirely implemented on plan9. Here's what I tried.
I tried setting up a udp announce directly against /net/udp for port 564.
Before listening I sent an addmulti message as described in the ip manual page.
