Udpcast for streaming data.
by Jorge Muñoz Castañer 31 Dec '09

Hi list, I was looking for a tool to send a stream of data with FEC where the client/receiver can connect even if the stream has yet begun. I haven't found anything but Udpcast that can do anything similar. I think that maybe an "streaming" option can be added so the sender sends Hello packets at the end of a block of slices+FEC so a receiver can hook to the UDP stream. What do you think about this? Can this be made modifying Udpcast without broken it all? Is there another software that I can use?

Missing Kernel Config & USB Memory Stick Probs
by Jens Breuer 30 Dec '09

30 Dec '09

Hello List, hello Alain, I recently wanted to download the current udpcast-kernel .config but the link on the Homepage returns 404 for me: http://udpcast.linux.lu/download/udpc-config-2.6.32-rc5.txt Additionally, I wanted to test some stuff with a USB-Memory-Stick but I could not manage to mount the filesystem (fat32) on the stick. I did not even see messages in dmesg regarding the stick being connected. I tried to test with a nonmodified udpcast-cd-image. I fear that this problem is not related to udpcast-framework but rather related to missing kernel or other framework features. However, after googling I am still none the wiser. I hope that someone can show me the right direction on where to investigate, so I can have full USB-Memory-Stick support. Thanks & Regards Jens

Network card Error
by Darin MacLachlan 30 Dec '09

This was working and now it has stopped. Have a UDPcast server running on a HP DL360G5 with 4 NICS. One connected to an internal infrastructure (eth2) and another connected to a dedicated switch with the client systems on the same switch (eth3). When i run the UDPcast send or receive, using the following command: udp-sender -f /home/base.udpc --interface eth3 --point-to-point --full- duplex --max-bitrate 600m --nokbd --portbase=9922 --min-receivers 1 -- rexmit-hello-interval 5000 --max-wait 300 I get the following error message: Udp-sender 2007-03-23 No suitable network interface found The following interfaces are available: lo 127.0.0.1 eth2 10.46.0.251 eth2:1 10.46.0.1 Interestingly, an ifconfig show eth3 as a valid network adapter, but the udp-sender does not see the device. This was working last week, and nothing has changed on the server I have tried everything, restarting DHCP, removing the interface and adding again. Rebooted the server, restarted the network stack manually. nothing seems to help. Using SUSE linux 10 as the base server OS.

unicast with async
by Justin Lipman 29 Dec '09

29 Dec '09

Hi folks, I'd like to use udp-sender with async and a unicast address instead of multicast so that unicast at the MAC layer is actually used. Ive tried using the pointopoint switch, but I get the message "pointopoint mode set, and 0 participants instead of 1". Is there a way to do this with udpcast? Thanks kindly. J
