If udp-receiver is writing to a pipe and the pipe fails, udp-receiver
will incorrectly exit with a returncode of zero. This is easily tested
with a trivial pipe program that copies stdin to stdout, but exits with
a nonzero status upon encountering eof.
Adding the following to startReceiver() in udpr-negotiate.c is
sufficient to fix this behavior:

I was just looking out for drivers for NIC and Hard Disk. Their model
numbers are as follows,
1) Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC(NDIS
1) WDC WD2500 AAJS-60M0a0 ATA DEVICE
2) Hitachi HDP725016GLA380 ATA DEVICE
Can you suggest me any other driver which can be compatible with this model
of the hardware.
--nosync do the trick
But still a lot of re-xmits, ie

Sorry for my English.
I have been using udpcast (PXE or a custom Debian Live) over the past two
years (version 20100130) and I recently upgraded to the latest version (
20110710), the old version got a transfer rate of about 480Mbps, with feww
reemissions (approximately 10 re-xmits) with the new and the same teams
involved does not exceed 43 Mbps. I tried to disable ipv6
(ipv6.disable = 1) but
there was no difference.
If I use the udp-sender (20110710) with the udp-receiver (20100130)
recovered the rate of 480 Mbps.
How do I find out why the number of re-xmits increases significantly?
Thanks in advance
I am using Udp-cast and I am happy, but some of the new mashines I have
bourght dont work with it. The kernel dont know my harddisk-controler (I
think) så it cant find my disks.
Are you planning to make a new version soon, with kernel 3?
