Well I saw that the export section, which
interests me the most, of the 2.3 version differes from that of the 3.0a -
obviously it has some more functions exported, but to my surprise some
functions are also missing !!! Namely PacketResetAdapter and PacketWaitPacket
which kinda renders the backward compatibility null. But still, this doesn't
bother me cause I don't use the missing functions, what bothers me is that now
the PacketGetAdapterNames is different, I mean I get different info from
the driver when calling for the adapter names which doesn't scale well in my
app and I don't quite "get it" why. After all the adapter name doesn't change,
right? I'll take a closer look at the examples.
My card is a plain ethernet (Accton EN2242
100Mbps) which works flawlessly with ver 2.3 on capture, but if I try to send
packets I get the BSD.
I'm using the packet API cause the pcap API is
"too simple" and too high up in the stack and from the pcap source I saw that
what I do in my app is the same as pcap does, of course not as efficient but
performance is not a big concern now, I need functionality first and then
speed. One other reason I use the packet API is that in order for me to use
the pcap API I'd have to port a lot of data structures and types. I know
there's Lars's translation to Delphi for the pcap headers and types but I
started using WinPcap before I knew about Lars's work and is too much hassle
to switch to pcap now, especially since I get what I need from packet
API.

Well, WinPcap 3.0 is backward compatible with 2.3.
I suggested you to wpdpack 3.0a since we have corrected
some bugs in the examples, and we have added a brand new HTML documentation
and tutorial.
Regarding the crashes, on which network adapter are you
using winpcap to send packets? Is it ethernet or PPP? Or anything
else?
GV
PS. Why are you using the packet API?
We usually suggest users to use the pcap API, which we think is much more
simple, and yet powerful.

well, I don't use the wpcap library (u
know... pcap_open_live and stuff), I use only the functions exported by
the packet.dll
I have both 2.3 and 3.0a but the packet.dll
doesn't seem to know about all the functions from ver. 2.3...how come?
isn't there a backward compatibility?
what do you mean by upgrading the wdpack?
I've donwloaded both versions couple of weeks ago...

Try winpcap 3.0alpha (remember to upgrade the
developers' pack, too).
GV
PS. What do you mean by "I use Packet.dll and
packet.sys and do not go through the API"?

Hi,
I wrote an app that uses WinPacap ver.
2.3 (I use Packet.dll and Packet.sys and do not go through the API) to
capture packets and if the TCP port matches a certain value than it
writes a new packet that closes the connection (it's not a DoS tool,
it's ment to be a intrusion prevention and access control tool so
don't bite my head off yet). Form time to time I get a STOP fatal
error on my W2K Server, the message error was that the irq was less or
not equal to...or something like that, it was acompanied by a blue
screen and a memory dump). I read in a previous post that this problem
is not a singularity and that it has been fixed. Could it be that I am
doing something worng (i.e try to write while reading or something
like that?)
I did take some precautions in my
app so I don't step over my own toes (a flag that is set when I read
and prevents my write to occur) but this thing still
occured.
