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. -- Richard Urwin, Software Design Engineer Schenck Test Automation Braemar Court, 1311b Melton Road, Syston, UK.

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 Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
