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
Thanks,
Devin Bayer
Hello,
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
start.
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.
Regards
Jens
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.

Salut,
nous somme en train de réaliser un PFE en réseau informatique concernant le clonage massif a partir d'une interface web personnel, pour cela nous avons besoin de votre aide et de vos connaissances a propos des notions de partimage et UDPcast et drbl...
Merci d'avance Mr.

Hello
I want to load some kernel modules per default.
I have add lines to "/init" in the /usr/lib/udpcast/tmpl-tree.
----- Ex.:
!/bin/sh
#mount -t devfs none /dev
modprobe sata_sis <--- This is my new line
modprobe floppy
modprobe uhci-hcd
modprobe ohci-hcd
modprobe usbkbd
mount -t sysfs none /sys
/bin/udpc_dialog init
exec /bin/init
-----------
After making the initrd-image, and booting per PXE this image,
- i have include a prescript to make a pause before the menue appaers
(prescript: read dummy (for continue after keystroke)
At this time i activate a virtual console on ALT-2
and with lsmod my module isn't in memory.
How/where can/must i include my modprobe line to load it as soon as
possible?
greeting
Uwe
I'm C a programmer, looking for Linux UDP multicast programming
documentation.
Early I'm write some UDP multicast program for WIN32, using API, it is
working on NT4.0 (loop back does not work, you can not switch off own
packets), W2K and WINXP - where I/O completion port is exist.
In WIn32 API you can simply setup an UDP socket, bind on apropriate
interface address and after using IOCTL set ADD_MEMBERSHIP/DROP_MEMBERSHIP
you can "join" to many groups _ at most I have tested is 4 groups like
224.0.0.xxx on the same port number (for example 6000).
In Linux I had managed to use multicast UDP port but, it seem to be that
it could not "join" to many groups, to receive packets, only one and you
should bind on it (for example on 224.0.0.10:6000)!
Is this right? One UDP socket could receive UDP packets only from one
multicast group in Linux?
