It
will affect all sniffer apps, regardless of whose driver is
used.
Hope
it helps.
Thank you,

[WinPcap-users] Logging problem with Server 2003
Hi
Gianluca,
I am
using a Dell desktop with an Intil PRO/1000 MT Network connection
card.
The
interesting point is that this machine was working on windows XP professional
and it had no problems but the moment I installed windows 2003 then I have
been having this logging problem.
I
have used several different tools than Ethereal (all of which rely on winpcap)
and I have the same problem with all of them. For your information, I tried
winpcap 3.0 and 3.1b4 but with the same results. Any
ideas?
Many
thanks in advance
Stamatis
Hi.
It's rather strange. WinPcap does not
interact with the TCP/IP stack in any way (apart from retrieving the IP
addresses of each newtork adapter).
Do you have any VPN/Personal firewall
software installed on your machine? Can you provide me more details on the
hardware (network cards) you are using? Your network card seems to
perform IP and TCP checksum offloading (i.e. the IP and TCP checksums are
computed by the board, instead of the tcp/ip stack).
Have a nice day
GV

problem with Server 2003
Hi,
I have recently installed ethereal with WinPcap 3.1b4 on a windows
2003 server but it appears that I cannot get logged any traffic
originating from the server unless a TCP flag has been set.
For example, the attachement has a log of a file transfer but no
packets appear to transmitted from the server although acknoledgements
arrive regularly. A close examination of all server originated traffic
shows that all logged packets have at least one TCP flag set.
I tried other logging
applications as well and all of them had the same problem with Ethereal
and I was wondering if there is a particular issue with WinPcap. For your
information, the same problem appears with WinPcap 3.0.
I'd really appreciate
if you could point out what might be the problem in this case.
Many thanks in advance,
Stamatis
