No, it can't do so, for the same reason that the Delphi component can't
do so - WinPcap 3.0 *itself* can't do so (they removed the ability to
handle PPP devices in 3.0, as there are *many* problems with it, some
of which can cause system crashes), and WinPcap 2.3 can *sometimes* do
so if you have the Network Monitor driver installed (as long as you try
to access the correct device, which is the one that has "bh" or "Bh" or
something like that in the name; "bh" stands for "Bloodhound", which
is, I think, Microsoft's internal name for Network Monitor, it being
like a bloodhound dog, sniffing the network) but can't always do so.
or can you give me the suggestion to capture tcp package from dial-up
and adsl connection?
Un-install Windows, and install BSD or Linux instead. (I'd suggest
BSD, as Linux's PPP-sniffing support, while it's not as bad as
Windows+WinPcap, isn't as good as BSD's.) There's even apparently a
Delphi for Linux:
http://www.borland.com/kylix/
as Kylix supports Linux. (Whether the Delphi Pcap component works is
another matter. I don't use Delphi, so I can't help you with it.)
This isn't really an Ethereal issue; you should probably ask further
questions on the winpcap-users mailing list:
http://winpcap.polito.it/contact.htm
You have to subscribe to the list in order to post to it.
