Hello.
I''m new to this list.
I''m trying to set up multicast routing between two networks:
Internet
^
|
Windows box
|
|
UserModeLinux A <-----> Colinux Router <-----> UserModeLinux B
running mrouter
I''m using a 2.6.8 kernel on Colinux with Multicast/Multicast routing
support activated.
The UMLs are supporting Multicast.
I''m trying to make A and B communicate over a Multicast address with
the
emcast utility.
Mrouter on Colinux is receiving the membership report from A end B.
Mrouter is also filling the tables:
colinux:~# cat /proc/net/ip_mr_cache
Group Origin Iif Pkts Bytes Wrong Oifs
080706E1 0114A8C0 2 3 117 0 1:1
080706E1 010AA8C0 1 4 123 0 2:1
^
|
Output Interfaces
But nothing is forwarded:
colinux:~# cat /proc/net/ip_mr_vif
Interface BytesIn PktsIn BytesOut PktsOut Flags Local Remote
1 tap0 123 4 0 0 00000 FE0AA8C0 00000000
2 tap1 117 3 0 0 00000 FE14A8C0 00000000
^

Nothing Out
I surely missed something but don''t know what.
I would be pleased if anybody could help...
Thanks in advance, Yoann

Emcast has the "good" idea to set the default ttl to 1. So be careful
!!!
Emcast -t 2 and it passes the router...
I hope nobody else will lose so much time !
Bye
