Q 5.12: I'm running Ethereal on Windows NT/2000/XP/Server; my machine
has a PPP (dial-up POTS, ISDN, etc.) interface, and it shows up in the
"Interface" item in the "Capture Options" dialog box. Why can no packets
be sent on or received from that network while I'm trying to capture
traffic on that interface?
A: WinPcap doesn't support PPP WAN interfaces on Windows
NT/2000/XP/Server; one symptom that may be seen is that attempts to
capture in promiscuous mode on the interface cause the interface to be
incapable of sending or receiving packets. You can disable promiscuous
mode using the -p command-line flag or the item in the "Capture
Preferences" dialog box, but this may mean that outgoing packets, or
incoming packets, won't be seen in the capture
Your options are:
Capture the data elsewhere. On the server for example (assuming that
that is not also a WAN interface)
Insert a router (eg another W2K machine) between the VAIO and the WAN
link so your laptop uses an LAN interface.

Hi all,
I installed Ethereal 0.9.8.c (and winpcap 2.3) to capture HTTP traffic
from my win2k laptop to a development server. However, when I started to
capture from the interface (e.g., \Device\Packet_NdisWanlp), nothing is
captured at all. All the statistics showed 0%.
I've tried to turn off all name resolution, promiscuous mode, different
interfaces (\Device\Packet_NdisWanIpMbfOut...), rebooting, ... to no
avail. I have also downloaded windump which gives the same problem. It
seems that my winpcap is not working but there's no admin program for me
to tweak. What gives ?
Thanks in advance for any help.
Regards,
Jin-Ho
P.S. I'm using Sony VAIO laptop if it makes any difference
