Hello Leif,
Check with
$ ifconfig -a
On my stock debian, ifconfig -a shows:
eth0 Link encap:Ethernet HWaddr 00:06:5B:87:ED:7D
inet addr:192.168.129.2 Bcast:192.168.129.255

In fact I logged into all the systems I have access to and they
all show multicast enabled on the network interface. I think that
shows that we are good to go? Also many more recent discovery services
require multicast to be operational.
So it must be a pretty widespread practice.
Maybe users on this list can report different or similar?
On the kernel, I generally agree, but debian variants again provide
good support for building new kernel/modules. But it remains a step
that is best avoided in the Linrad user base, the learning curve is
already pretty steep.

Thanks. The immediate problem that pops up is here:
In order to play with multicast,
your GNU/Linux box needs special configuration.
Recompiling the kernel is no longer an easy thing.
Nowadays it is even difficult to compile kernel modules
since modern distributions do not contain the necessary files.
One can sometimes download the source code from the Internet,
but then it will be the latest kernel with a possibillity
to choose from a couple of older ones, but it will not
be possible to download the really old one from which
the kernel of the distribution was built.
It seems that before considering multicasting I need to
verify that modern Linux distributions are compiled
with the necessary options enabled. How do I find out?
The way I was used to "make config" does not work, presumably
because of missing files.....
Anyone knows?
