Hi all,

Just started playing with winpcap, and first of all thanks for all the good 
work!

Now, even though I can capture data OK, I also need to send some raw 
ethernet frames. I use pcap_send_packet, but other than having my packet 
appear in my filter and WinDump (sometimes multiple times!), I don't 
believe it's ever sent on the wire.

I also tried the sample TG.exe (which uses packet.dll directly), but it 
doesn't seem to be more successful.

I'm running W2K SP2, and tried the operation both on a WLAN card (True 
Mobile 1150/Orinocco) and wired Ethernet card (Xircom RealPort 10/100). I'm 
compiling my bit of software under Cygwin in no-cygwin (mingw) mode, and 
use the TG.exe binary in the developer's package.

When I say I don't think anything is sent, that means there are no LEDs 
blinking, no logs of traffic (on AP using the WLAN card)...

Note also that I have a couple of VPN clients installed (Nokia VPN client 
and Cisco VPN 5000 client), but until now I've never seen any side effect 
of those, so I don't know if they might be to blame or not.

So, questions:
1. is sending packets really supposed to work? I guess it should.
2. are there any known limitations (doesn't work on some OSes, some types 
of cards...)?
3. should I be able to send any Ethertype I want?
4. any hints as to why this doesn't work?

Any information welcome!

Thanks,

Jacques.
