Deat simha,
based on what you are reporting, I propose the following suggestions:
1) check the routing tables of the virtual machines (routes for multicast
datagrams should be set);
2) download the new filesystem release from
http://www.netkit.org/download/netkit-filesystem/netkit-filesystem-F3.0a.tar
.bz2, which includes tools that enable support for multicast routing (e.g.,
mrouted).
Hope this helps,
Massimo.

Subject: [Netkit.users] Setting Multicast address on eth0
Hi,
I need a UML m/c configuration as follows:-
m/c1 - eth0: 10.1.1.2
m/c2 - eth0:10.1.1.3
They are in the same collision domain so I can set the eth0
interface collision domain to "A" in the lab.conf file.
An application in both the UML instances need to do a MULTI CAST
join on the multi-cast address 225.0.0.37.
The application does a setsockopt(.., IP_ADD_MEMBERSHIP..)
subseqently the app does a sendto on the multicast address.
Currently when I run the app I get a "Network un-reachable error"
How do I configure the lab.conf so that the multicast is enabled in
the UML instances?
I have enabled the MULTICAST and MULTICAST ROUTING support in the
UML kernel build.
Thanks,
simha.
