Hello,
I have a Windows XP PC running Ethereal 0.10.3 and WinPcap 3.0.
Over PPPoE, the PC has been assigned the private IP address 1.1.1.4 which is
later NATed on the DSL modem to a public address. The connection is working
properly and the PC has access to the Internet.
If I run Ethereal on this PC without any filter on the Ethernet interface I
can see the packets coming in and out. But if I configure any kind of filter
on Ethereal, it does not capture any packets that are destined to or come
from the PPPoE IP address.
I have tried very simple filters like the following with these results:
Filter: tcp
Result: Ethereal sees packets from or to other hosts that are connected to
the same hub, but none from or to the PPPoE IP 1.1.1.4.
Filter: host 1.1.1.4
Result: Ethereal captures no packets at all.
Filter: "none"
Result: Ethereal captures packets from or to all IP addresses connected to
the hub, including the PPPoE address of the PC (1.1.1.4)
Of course, I am sure that the PC is generating traffic when I run Ethereal,
the problem being that Ethereal does not see it when a filter is applied.
From time to time I get the following message in a command window, and I do
not know if it has anything to do with the problem:
(ethereal.exe:1472): Gdk-WARNING **: [Invalid UTF-8]
gdkdrawable-win32.c:blit_from_pixmap:798: BitBlt failed: Controlador no
v�lido.
Any idea?
Fran
