I have tried using UDP sockets, but this has resulted in high CPU load and
lots of lost packets. Ideally I would use a zero-copy UDP socket, but this
is not available yet. Even receiving UDP packets to the windows "discard"
port (9) installed by the "Simple TCP/IP Services", results in a quite

Hello,
For some reason "windump -D" is not working on my computer.
I am getting:
"windump: PacketGetAdapterNames: Cannot create a file when that file
already exists."
What can be the reason?
Thanks

The WindowsCE porting of winpcap supports only the low-level packet.dll
library (PacketXXX functions). Moreover, as the download page states, we are
not able to give support for that version, and we currently don't have a
maintainer for it.

Paal,
no, it's not possible to increase the priority of the WinPcap driver.
Actually, changing the priority is a concept that doesn't make a lot of
sense when talking about drivrs (the packet-capture part of the winpcap
driver runs at DPC level, and therefore has higher priority than any other

Hi,
I'm not familiar with vnc, but wrote a checksum routine at one point. Double
check that the checksum is correct,
easy way is to use etherreal which will show you if checksum is invalid.
It's possible that the checksum was inalid and passed through anyway.
If it's not checksum, if vnc is a tu
