Hi everybody,
I have problem with udp-receiver, it is unable to store files
larger than 2GB.
I have read older post and found some work around (udp-receiver > image.gz)
but this did not work either.
my config is:
CPU P4 2,4GHz, RAM 512 DDR, HDD WD 120GB, NIC RTL8139 (8139too driver),
i run debian woody orignaly (2.2) kernel but i upgraded to 2.4.18-686,
i use udpcast 20030831,
partition where i store image i big enough and has reiserfs
i administer small lan, about 15 winxp boxes
any hints?
thanx,
der3k

I used a similar set at the sender-side ( $ udp-sender --pipe "dd
if=/dev/hda1/" ),
but I don't see why the way how you send stuff affects the maximum storage
size on the receivers end. Can anyone think of something?

A Help, Please!
I need to distribute an Image to 40 clients. The resolution of this
image is 1560x1024, and the Max refresh is 1 frame per second. This
Image is in my pc screen, so if I distribute my screen to the clients,
I´ll distribute this Image. This is possible with the software Udpcast??
The clients can be Win2000?? How can I see this image in the clients??

First let me say that udpcast is a great tool. I use it in SystemImager
as a multicast transport option, and it works quite well.
I do have one conundrum, however, in that I'm trying to do a
--pipe 'tar -x' on a busybox system, and regardless of the exit status
of the --pipe program (tar in this case), I get an exit status of 141
from udp-receiver. The files, however, are untarred successfully.
If I issue the same commands on a non-busy box system, things work fine.
If I receive the stream to a file, --file /tmp/out, udp-receiver exits
with a zero.
A statically compiled udp-receiver exhibits the same behavior.
This is with udpcast-20011231.
I have even applied the patch below, which produces appropriate exit
codes when run on a non-busybox system.
Help!
Thanks, -Brian
