I'm sure I did this several months ago but can not get to work now. Have 2 Nics in PC: 192.168.61.201 and 202. NICs are connected thru switch. Normally if I ping 202 no packets would go out PC but 201 would ping 202 thru backplane.
If I use WinPcap.SendQue and XP SP2, it appeared (based on switch stats) that ICMP request packet from 201 went to switch and response packet from 202 went to switch and then to 201 NIC. Trafffic appeared in Wireshark. My belief was that WinPcap.SendQue forced packet out.
Does this seem correct analysis ?
Now using XP Pro SP3, previously used SP2 when it worked for capturing both ICMP requests / replies. Same symptoms with wireshark.
As to example code, it is essentially same as example here:http://www.codeproject.com/Articles/12458/SharpPcap-A-Packet-Capture-Framework-for-NET
with send que in section:Send queues - WinPcap specific extension (Example 10 in the source package).
Thanks to all
