<DIV><FONT face="Courier New" size=2>Just a quick question: why are you using
the Packet API instead of the pcap one?</FONT></DIV>
<DIV><FONT face="Courier New" size=2></FONT> </DIV>
<DIV><FONT face="Courier New" size=2>I hope you have read the big notice in the
documentation:</FONT></DIV>
<DIV><FONT face="Courier New" size=2></FONT> </DIV>
<DIV>
<H2>Important note, read carefully!</H2>
<P>The source code of Packet.dll is freely available and completely documented.
However, packet.dll should be considered an internal API, because its purpose
inside WinPcap is to be a building block for the real public API: wpcap.dll.</P>
<P>As a consequence, since the <B>normal</B> and <B>suggested</B> way for an
application to use WinPcap is through wpcap.dll, <B>we don't guarantee that the
packet.dll API will not be changed in future releases of winpcap, and we don't
provide support for this API</B>. For the same reason, <B>this manual doesn't
contain any more the Doxygen-generated documentation of Packet.dll</B>: the user
will have to run Doxygen on his own to create it, or read the comments in the
source code.\\\</P></DIV>

<DIV><FONT face=Verdana><TT><FONT size=2>I made a deeper look. The problem I
mention is the reason of your problem.<BR><BR>The size of ethernet header for
IPv4 is always 14 bytes (6 bytes + 6 bytes + 2 bytes).<BR>Your definition is
16+16+2=34 bytes long. And further in the code you're using <FONT
color=#666666>sizeof </FONT>keyword:<BR></FONT><FONT
color=#666666><BR></FONT></TT><FONT size=2><FONT color=#666666>//get ip
header<BR>ipr = (IP_HDR
*)(pchar+sizeof(ETH_HDR));</FONT><BR></FONT><TT><BR><FONT size=2>So <FONT
color=#666666>ipr</FONT> poiter points somewhere to the IP packet data but not
to the header of it.<BR>So simply change [16] to the
[6].<BR></FONT></TT><TT><FONT size=2>I'm sure it will
help.<BR><BR></FONT></TT><TT><BR></TT><TT>I think the code you send us is not
yours so you can't find the problem yourself. :)</TT><BR><FONT
