[coLinux-users] colinux 0.6.1 network patcket loss

[sophana <sop...@ya...>]

Hi

I installed a redhat 7.3 image with colinux 0.6.1 with XP sp1, with tap 
network (winpcap 3.1 beta)

I use XP native ethernet bridging.

First question: does the tap network driver uses winpcap?
which version of winpcap is the best? (3.0 or 3.1beta?)

There are some strange network problems: when I ping from colinux to 
another machine, I have 0% packet loss.
When I ping the other machine to colinux, I have about 20 to 30% packet 
loss.
when I do bidirectionnal iperf  I obtain about 20mbit from colinux and 
30mbit to colinux (100mbit fast ethernet switch with broadcom bcm5700 
gigabit controller)
With bidir iperf under windows, I have 20mbit upload and 90 mbit 
download. (90mbit both ways when half duplex)

Does any have have the problem of packet loss?
Is it a known problem? there is a post on the list indicating problems 
with nfs because of packet loss also?
Is there a solution?

I suspect macAfee antivirus... (I cannot remove it because of the IT guy 
here...)

One more strange problem: top indicates all process usage under system 
usage. the user cpu usage is always 0...

Thanks
