Hi
First of of thanks to developers for this great tool.
I am trying to use it over vpn connection but I cannot get the server and the client to see eachother. I define the interface in the commandline as tun0 but that is not doing the job. My Vpn has 10.30.0. range.
thanks
Just setup some new machines with Fedora 20, and was going thru the
process of building the udpcast, and got an error message that fd_set was
not defined in console.h. Did a check and this is defined in sys/select.h and
that is listed in the socklib.h, so not sure what the issue is?? I added the
include of sys/select.h in console.h, and then the make went thru with no
problem.

Alain,
I'm trying to perform a packet capture of the data transmitted by
udp-sender using Wireshark and am running into the exact same problem
encountered by Lance 8 years ago. (posting listed below.)
What information can I provide to help debug this issue?
Also, can you tell me if the multicast data sent includes a sequence
number and does the receiver have the ability to filter out duplicate
multicast frames?
Regards,
Chris

I have used the lattest version of udpcast (udpcast-20050226.tar.gz)
as well as used ethereal version 0.10.12 and
I still get the "Bogus IP header length (0, must be at least 20)" I
will continue to try this on different Platforms with different
network switches and see what I get.

Hi all,
The attached trivial patch fixes a build failure on the AArch64
architecture. The sys/select.h header is required by POSIX to get the
definitions for fd_set and struct timeval.
Thanks,
Hi,
I am working on Multicast Download using *Windows Version* of UDPcast
application. I want couple of information on UDPCast tool.
1. Can we transfer multiple files using single command line from sender?
2. Is it possible to identify the Name of the file being transferred at the
reciever end?
Thanks for the help in advance.
Thanks and Regards,
Prasad
I'm using udpcast everyday on a large scale setup (between 100 and 500 per install) while counting more than 3000 devices using it at the total.
Udpcast runs on an Intel ATOM E600 that features a very weak pch_gbe network driver (linux 3.2 series + Preempt-RT).
I'm trying to be as fast and as reliable as possible in a one-way setup.
We do have some post-processing on the output stream also to insure coherency & performance (required by our use case).
Streaming at 220Mbps with an 8X8 FEC leads to a very high cpu usage & system load.
The only way to get it stable is at least to change it priority by using "schedtool -R -p 10 udcpast".
Since I'm running this setup I'm loosing very few packet.
Maybe this approach could help some while debugging udpcast on low-end cpus.
Cheers,
Erwan
Hi Alain,
I've been sending an email in november about I bug I had on my setup.
http://www.udpcast.linux.lu/pipermail/udpcast/2012-November/001194.html
Since I'm running this commit I never had the problem again (while it was present at every run before).
I never got any formal feedback about it to see if it's the proper way to solve it.
I really would like some comments on it.
Cheers,
Erwan
Hi All,
Our application provides download solution to devices connected to network.
Currently its point to point download, so when the download is scheduled
concurrently for more devices IIS gets blocked and file download gets failed
due to which hardware requirement of our product increases.
When we started looking for multicast solution we found that UDP cast tool
providing faster download of 1GB file.
But we couldn't find windows version source code.
May I know the process to get source code of UDP cast for windows version?
Much appreciated your help.
Thanks and Regards,
Aruna Veluru
Hello all,
I can't see any contacts info on the site.
I just want to say thank you so much for a great piece of code!
I was looking for something to use in my data diode project that
supports unidirectional UDP and FEC.
I stumbled across UDPcast and was overjoyed!
Thank you.
Hello everybody,
udpcast is missing an include for sys/select.h. The attached patch fixes the
issue.
