Hi. The problem is that PPP under NT/2k/XP doesn't follow the NDIS standard. PPP in Microsoft OSes has several non-standard behaviors that make it very difficult to support it properly.

Hi, There is a problem when making a dial-up connection (noticed both with WindowsNT and Windows2000) and then starting Ethereal; Ethereal doesn't show/record (it gets stuck) the data and the dial-up connection is interrupted. As soon as Ethereal is stopped, the dial-up connection is going on normally. When I asked to Ethereal some support I got the following answer (coming from WinPCap FAQ): " We have tested WinPcap on PPP connections under Windows 95, Windows 98 and Windows ME. In Windows 95, due to a bug in NDIS, WinPcap sometimes resets the PPP connection. In Windows 98/ME this bug appears to be corrected, and WinPcap seems to work properly. Under Windows NT and Windows 2000 there are problems with the binding process, that prevents a protocol driver from working properly on the WAN adapter. The only way to solve this problem is either to 1) not use any application, such as Ethereal or WinDump or Analyzer, that uses WinPcap; 2) don't use Windows NT (4.0, or 5.0 a/k/a "Windows 2000", or, probably, 5.1 a/k/a "Windows XP" or "Windows .NET Server"); 3) get the source code to WinPcap, and get the Windows DDK from Microsoft, and attempt to figure out how to make WinPcap's driver work with WAN interfaces. " Could you explain me why and how to solve this problem? Thanks a lot for your support. Christophe Landemaine Network Planning Engineer - 3G&IP Phone: +358 7180 66861 mailto:[EMAIL PROTECTED]
