card directly in wpcap.dll. If so, the p->adapter field is a NULL/bogus
pointer, so there Packet API will receive a NULL/bogus pointer!</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [Winpcap-users] Problems with
the modified wpcap.dll in Wireshark</DIV>
<DIV><BR></DIV>Hello,<BR><BR>We have developed our device to capture ss7
traffic on a TDM link.<BR><BR>Once we start our device, we get this message.
<BR><BR>" Couldnt set capture buffer size Size 1MB seems to be too high
for your machine <BR> default is 1MB Any way capture started.
"<BR><BR>and it takes some time before the packets are being displayed on the
GUI. <BR><BR>As I heard it comes with the Win32-only pcap_setbuff() routine
not being set<BR>up to handle add-on capture interfaces such as ours. As I saw
this is done by <BR>the function PacketSetBuff(p->adapter,dim), which I
suspect a function to <BR>change the driver behaviour, for which I do not have
access. <BR><BR>Where is this PacketSetBuff() written?<BR><BR>If its on user
mode and doesnt need the ddk, can I change it so that I can <BR>overcome this
problem. Or any way I can overcome this! :-)<BR><BR>My next question is our
GUI freezes when a live capture is going, and we are <BR>not able to stop the
live capture when we need. What could be the problem <BR>for this? It keeps on
capturing data at some speed around 128kbps. <BR><BR>Kind regards
<BR><BR>Varuna De Silva<BR><BR><BR><BR><BR><BR>
