Hi All,
Just to let you know that I found the cause of my problem described below.
My company runs F-Secure anti-virus software.
I uninstalled all components of F-Secure and suddenly I could see all
packets and my network communication was not disrupted any longer when I
started a capture.
It would seem that F-Secure and WinPCap do not work together.
I will inform the WinPCap developers as well.
Kind Regards
Andre

Subject: Ethereal disrupts my network communication - Please help?
Hi,
I'm new on the list and hoping for some help with a problem:
I experience the following:
I ping my gateway (or any other address) on my network continuously and get
replies to all my pings.
Then I start ethereal and start a new live capture (promiscuous mode or not
makes no difference).
As soon as the capture is started, the pings start timing out.
When I stop the capture, the pings start replying again.
When I examine the capture, I see ICMP reply from my gateway, but I don't
see the ICMP request being sent to the gateway.
I have read the FAQ's and just to save some time please note the following:
I don't run any VPN software that I am aware of. How can I confirm this?
What do I look for?
I have tried capturing with both promiscuous mode on and off, but with the
same result.
I have tried the on board Intel LAN interface and also a Xircom RBE-100
PCMCIA NIC and also a 3Com Megahertz Model 3CCFE575CT PCMCIA Adapter, but
all with the same results.
I have also tried turning "Offload TCP segmentation" on and off with the
same results.
Can anyone help me with some suggestions as to what to try next please?
Kind Regards
Andre
