That was surely the intention of the WinPcap developers, but practice and "implicit" rules like ASCII naming are used only on Win-9x and Unicode on Win-NT was broken in the 3.1 update. Many programs (including nmap) makes this assumption. Not really surprising since many of the WinPcap examples does the same thing So instead of breaking this rule, our Italian friends should IMHO have created a new function that returns ASCII on Win-NT+ and a backward compatible function that returns Unicode on Win-NT+.

Or compile it yourself? BTW. There are other problems with pcap_open_live() in 3.1; If you pass a device on a machine with >= 2 devices (in my case the RealTek eth adapter and the IPv6 pseudo tunnelling device), the PacketOpenAdapter() will fail since (OTOH) the list of *all* devices hasn't been found at that point (since PacketGetAdapterNames() and PacketPopulateAdaptersInfoList() hasn't been called). An easy fix is to do "(void) pcap_lookupdev(errbuf)" (or pcap_findalldevs*()) before pcap_open_live() on the device you want to use. --gv GNU GPL: Free as in herpes. ================================================================== This is the WinPcap users list.
