Hello. Thanks for developing udpcast. It almost compiles on my
mac. But I have to make a few small changes.
1.) the linker doesn't support the -Wl,-warn-common option
2.) what is malloc.h? It isn't needed.
3.) struct ifreq is variable size, so we must use _SIZEOF_ADDR_IFREQ
(), not pointer arithemetic
4.) some endian issues
I am curious whether there is an commandline option which could
instruct udp-receiver to exit after a certain amount of time without
any udp-sender activity or generally when the transfer process doesn't
At least I could not find anything in the documents.
We use udpcast together with PXE-boot and sometimes some machines are
simply not responding to the sender (why is yet unclear). After
manually restarting the machines it is usually the case that the
machines to be imaged are responding again and everything is well.
Unfortunately it could be the case that there are machines to be
imaged which are placed in locked rooms and so it is impossible to
restart them manually.
I've done some googling and found a few posts which seemed to indicate that
udpcast shouldn't have problems working with a usb keyboard. Nonetheless,
when I boot a pc from the cd or pxe, the keyboard does not work. Where
should I start in troubleshooting this problem? I am very much a linux
noob, but if someone can get me started, I believe I can stumble my way
through it. Thanks.

Current kernel doesn't support new version of intel network card.
I build an iso image with my 2.6.18 kernel (not optimized for udpcast: it is
the one I use on my computer running debian etch) and it works.
Network card is recognized as e1000.
2.6.17-5 Mandriva 2007 kernel recognize it as well.
Do you plan building a new udpcast-optimized-kernel?
Last stable version is 2.6.19...
Thank you very much!
I hope you'll understand the froggy way I write english.

I had the same problem with usb keyboards. The following solution worked
1. Create an image with the cast-o-matic wizard (
2. On the second page of the wizard, there is a field called " Commands to
be executed before udpcast menu:"
3. Add the following lines of code into that field:
4. Finish creating the boot image and see if it works for you.
