December 2008 - Udpcast

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.

Bandwidth issue with Net Express bonded nics in Windows
by [STD]Ein 24 Dec '08

24 Dec '08

Using the latest udpcast (udpwindows port, I cannot obtain more than 15.2mbit/s when using a net express bonded nic as the receiver. This virtual nic has no problems obtaining 90mbit/s with smb or ftp (the 'bonding' is mac based outbound only and works as passthrough for individual clients), so it's not expressly (pardon the pun) an issue with that. Testing with other machines with normal nics (on the same switch with no changes in topology) I'm getting 45+ The physical nics are d-link dfe530tx rev c cards. There's no error messages (no resends at all). Any ideas? (other than ditching the nic express of course :p )

Other Application of UDPcast Capability (200812161107.AYC)
by Abraham Y. Chen 16 Dec '08

16 Dec '08

Dear UDPcast Members: 0) I am new to this mailing list. I was recently made aware of the UDPcast facility. I am impressed by its simplicity and cross- platform interoperability. 1) What brought me to you is the search for a networking tool that I have identified for many years. It appears that if we can configure the front end of the UDPcast (just the initial phase of "broadcasting" and "listening" part) to provide a near-real time overview of all active devices on a network, we can empower mass consumers with a pieced of crucial baseline information., that is, the instant health status of their SOHO (Small Office Home Office) or Residential network, even without an IT manager nor any technical know-how. 2) I am a system engineer trained in hardware designs emphasizing traditional RF and telephony. I can identify potential new applications based on capable technical ingredients within an existing product. However, I am not good at the actual detail implementations, especially software. Since UDPcast is the result of an open source effort, I thought that it would be prudent for me to check with you to see if anyone would like to work with me on the idea that I have, so that the outcome can benefit the general public. 3) For those interested in what our team has accomplished up to now, please have a look at a set of overview slides: http://www.avinta.com/phoenix-1/home/ProjectPhoenixPrimer.pdf With basic network architecture and transmission capabilities identified for satisfying MaP (Mom and Pop) type of users, we have been looking for the next level intuitive building block. That is, with so many devices possible on a SOHO network, how could an owner get a concise visual summary of which ones are currently online? Once this is provided, MaP will have a clear reference line to deal with potential cause of network issues, either by doing their own "unplug and swap" substitutions or having enough confidence to deal with techsupport personnels. 4) I will be glad to write then submit a product specification type of document describing details of my thoughts as an outline to begin more specific discussions, if anyone would indicate the interest in working with us. As implied, the end product of this effort will be a utility distributed to mass consumers for them to enjoy network services because they will be able to "manage" the very basics of their own network. I look forward to any thoughts and comments. Regards, Abe (2008-12-16, 15:03) Skype: Abraham.Y.Chen

Transfer through wireless network.
by Marcelo Martini 16 Dec '08

16 Dec '08

Hello folks, I would like to use Udpcast to send files through the wireless network I have here, but software doesn't identify the wireless pci card of computers, only the ethernet card. Looking in the "other" drive options, I didn't find the correct driver for wireless pci card. What can I do to use udpcast with wireless network using RaLink RT2561/RT61 rev B 802.11g ?? Thank you !! Marcelo Martini.

Failed to compile udpcast 20081130 using gcc 3.2.2
by Steven Shiau 14 Dec '08

14 Dec '08

Hi, I am having a problem to compile udpcast 20081130 using gcc 3.2.2. I got the error messages like: ... udp-sender.c: At top level: udp-sender.c:425: parse error before '}' token udp-sender.c:453: parse error before string constant ... The details are attached. Does udpcast only support gcc 4 now ? Thanks.

Changing computer names after broadcasting
by Doug Dougherty 02 Dec '08

02 Dec '08

Hello all, I've never used UDPCast but I've been ask to come up with a solution to image 20 computers at once in a training room. I figured I could have one computer set as a server and all others set to boot off the server, this way they would boot and receive only when the server computer was powered on. My problem is that each computer will have to have a unique name. If I broadcast the same image over the network how can I change the computer names without sitting at each individual computer, I'm trying to make this completely automated. Doug Dougherty
