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
Using UPDCast (CD Version) in a lab of 48 IBMs with SATA drives and
broadcom (5787) gigabit NICs. I'm not sure why, but when I start a
group of machines the transfer process goes along at a slow pace of
54Mb.
The network is all Linksys 1GB switches. Why is the xfer rate so low?
I've used UDPcast with the tg3 driver in the same setup with xfer rate
upwards of 500Mb. This machine has USB only (keyboard and mouse). I
finally got the keybaord to work but the xfer
I've downloaded Cast-0-matic hoping that would resolve the xfer rate
issue but to no avail. Please advise. I'm new to Linux/Unix and dont
know how to compile an image with the new driver from Broadcom.com.
Thanks
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.

Hi friends
I am a Danish teacher using UDPcast to clone the workstations on the school. I
have used UDP-cast for several years and have been very happy about it.
Now we have upgraded our computer system with 22 new workstations - and then I
got my problem:
The machines network card is omboard end uses the linux module r1000. It is a
Realtek RTL8168/RTL8111.
Realtek have made a GPL driver:
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFi…
And I found a RPM for my Fedora core 6 that works perfectly at
http://rpm.pbone.net/index.php3/stat/4/idpl/3743377/com/dkms-r1000-1.05-1.n…
But I can't use UDP-cast to clone the mashine. Now I have 2 questions:
1) Is there a way I can put the driver into UDPcast?
2) Are you planning to include a driver for my networkcard soon?
I hope you keep developing UDP-cast :-)
Good night

You're soaking in it.

Nothing wrong with a mailing list, especially one that has the
archives available online for searching.

Hello everybody,
cloning ata-disks worked beautifully with udp-cast --- thank you
very much!
My problems started when I tried to clone machines using sata-disks.
According to the mainboard documentation a VIA-controller is used for
sata-disks on the third and fourth ide-device. But no matter which
optional sata-drivers I tried to include in udpast - I tried the
VIA-, Intel, and Marvell-drivers - udpcast can't autodetect my disk
and I can't figure out what to input as a device in the 'other'
section. Whatever I enter (I tried hda and sda) is followed by a
message that 'no such device' is present.
I'm stuck!
I hope I've provide enough information to be useful.
Many thanks in advance!

I decided to try this program on a lab of 25 GX620s with SATA drives and
broadcom 57xx gigabit NICs. I'm not sure why, but when I start a group of
machines the transfer process goes along at a fast pace (~75Mb). However,
the process always seems to fail at different places during the transfer,
usually at about 800MB to 1.3GB of data. Sometimes it will recover and
start going again, but usually it just stops and all the clients are
dropped. I used udp-sender.exe on a Windows machine to transfer a GZIP'd
image created with G4U. I know the image is good, because I routinely use
it to unicast single PCs. On the target machines, I used the cast-o-matic
tool and selected all the SATA and NIC modules with Automatic detection.
The machines get an IP address and /dev/sda is detected Also, I verified
IGMP snooping is enabled on the switch.
I have tried limiting the --max-bitrate to 40M. I'm running in 100Mbit mode
--half-duplex (that's how the Summit 400 switch is setup). I've tried using
the option on cast-o-matic to force IGMPv2 mode, because I'm not sure if our
switch could be the issue. I also tried the udp-sender program from Ubuntu
(was the version from the default repositories.. might be old). It had the
same problem as the Win32 version. Although, the console had a lot more
errors than the windows version... I would get streams of Timeout
notAnswered notReady, etc messages in the console when the process would
halt. I've also tried setting the SATA mode in the BIOS to Combination.
Anyone encountered this problem before or have a suggestion? I'd really
like to use this program, because it seems perfect for my purposes (imaging
labs).
Thanks for any help or advise,
Jonathan Miller
