I'm looking at set up proper filter rules for an
adapter with two IP addresses. My question is: Does
winpcap work with adapter with multiple IP addresses?
I looked at the code, seems to me pcap_lookupnet() and
pcap_compile() both assume one IP address per adapter.
In the windump code(tcpdump.c)

Before, since segmentation is done on the NIC itself.

Hi.
We experienced a similar "problem" with one of our lab machines (using an
intel server Fast Ethernet card). In practice some network cards (server
nics, usually), are able to fragment outbound packets in smaller chunks (I
don't know how, exactly), so they announce to protocol drivers (TCP-IP a
Hi.
I'm not completely sure, because I don't know how the C_Paquet
constructor works, but I think that the problem is that you are storing the
pointer returned in pkt_data into your C_Paquet class. Unfortunately, this
pointer is valid only up to the next call to pcap_next_ex (or pcap_close)

Hi Robert.
You're right.
You have to build WinPcap woth this option turned on (which is one of the
variants of the project you can use to build the library).
This is to keep the stricter compatibility with libpcap, which is causing us
a lot of headache (libpcap does not have pcap_findalldevs_ex() a
Hi,
I am using pcap/WinPcap to capture traffic on linux and windows
operating systems. I need to work on several interfaces in parallel and
expect high load, however, as the filter function should drop more than
99 percent of the traffic, receiving packets from pcap should not be the
problem.

Hello all,
First time I used this mailing list so hello all

I program a c++ software to capture network traffic
and analyze it so Winpcap is very useful :)
But i got an issue with the pcap_next_ex function.

Hi,
I am using winpcap 3.1 beta. I am seeing IP packets on an 100 Mbit Ethernet
segment which have IP header total length > 2000. This causes Winpcap
library to return packet length and captured length to be greater equal to
IP total length + Ethernet header length.
Is this a bug in winpcap becau
