Hello all,
I've been trying to get dvbnet to pass multicast packets from a
datapid for the past week without much luck. I am using FC3, Kernel
2.6.10 and a cvs pull from 29APR05. I have an app that sends out UDP
packets on 225.0.0.1 in a data pid (0x2a). We'd like to be able to
receive them with a java app that reads from a nic in linux (this all
works in windows right now, and with BBTIs linux drivers in kernel
2.4). Currently I do:
./szap -l standard mychannel (leave this running, status 1f and signal
ffff etc)
dvbnet -p 42
ifconfig dvb0_0 promisc up (or allmulti)
echo 0 > /proc/sys/net/ipv4/conf/dvb0_0/rp_filter
route add -net 224.0.0.0 netmask 240.0.0.0 dev dvb0_0
As long as I use the promisc or allmulti options I get a packet count
under Rx dropped, otherwise I get no statistics on dvb0_0. Assigning an
IP does not seem to effect anything either.
dvb0_0 Link encap:Ethernet HWaddr 00:D0:D7:0B:32:DC inet
addr:192.168.238.238 Bcast:192.168.238.255 Mask:255.255.255.0
inet6 addr: fe80::2d0:d7ff:fe0b:32dc/64 Scope:Link
UP BROADCAST RUNNING NOARP PROMISC ALLMULTI MULTICAST MTU:4096
Metric:1
RX packets:0 errors:0 dropped:69399439 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
A couple of quick notes:
- dvbsnoop on the data pid shows the data no problem.
- tcpdump -i dvb0_0 does not output anything other than our
application sending IGMP joins, so naturally our java app doesn't
receive any packets.
I am not too confident that my configuration is correct, so any help
would be appreciated.
Thank you for your time,
Sean
