Network card Error
by Darin MacLachlan 30 Dec '09

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

UDP Cast ready-made boot images and i686 issues
by Henrique Rodrigues 03 Nov '09

03 Nov '09

Hello, I've been using UDP Cast extensively for a while now and I love it, but I had an issue last week and I want to share it witou you. The UDP Cast website provides handy ready-made boot images. Apparently, those images are compiled for i686 and I couldn't make them work on an older machine because the processor doesn't implement the CMOV operation. The problem seem to belong to GCC, because it thinks that every i686 processor implements the optional CMOV operation, which is not true. I solved the problem by compiling my own UDP Cast kernel, but I suggest that the next UDP Cast ready-made boot images drop the i686 requirement and stick to i386, for compatibility reasons. Is this a reasonable request? Thank you and best regards, Henrique Rodrigues -- Henrique Rodrigues http://sodki.org Engenharia Informatica e de Computadores - Instituto Superior Tecnico

As PXE booting is a somewhat more complex setup, you would need a separate PC (besides your udpsender and udpreceiver) which should run a (configured) tftpd and a (configured) dhcpd. Maybe you would be able to use Udpcast Image Generator to embed tftpd and dhcpd into udpcast. However, I would consider this a a pretty much time consuming task. So you really should try to get a third machine as a real server.
