MulticastSocket in Ruby

Ruby
1

Hi Folks,

I need some halp with Multicast Sockets. Is it possible to establish a
multicst socket in Ruby? I believe it ist, but have no idea how it could
work. I asked Google already for help, but with no success. So I ask
here. I already tried to solve this with using UDPSocket, but that
failed, too.

Is there any class, package or extension for this task or could you give
me a hint for doing this with the existing sockets?

Thanks a lot in advance.

Use the low level apis of class Socket. They behave almost the same as
the BSD socket apis.

If you want an example, multicast DNS uses multicast UDP, both send and
receive, look at http://dnssd.rubyforge.org, check out the source in
net-mdns.

Wow! That link is great! This will go quite well with
Net::DAAP::Client ( http://rubyforge.org/projects/daapclient/ ). Yay!

That looks pretty interesting, too, I’ll keep an eye on it.

You might want to use the cvs version, there are some new easier-to-use
apis in the C bindings, and at least one bug fix. Charles and I probably
should re-sync the APIs and re-release but we don’t hear much feedback
about DNS-SD, so its not very motivating.

Cheers,

Thanks a lot for your help.

Sorry that I response that late, but I had a little trouble with
finishing of my Bachelorthesis.

This here is for another project.

So thanks again for your help.
