RE: FlexResp Running (I THINK!)

["Burleson, Lee (IA)" <Lee.Burleson () ia ngb army mil>]

In Snort 1.7 under Win32, no function that sent packets worked.  The error
for me and others was
"packet: send_packet failed"
Supposedly the cause was WinPCap; the issue was never fully resolved in my
mind.
I'm wondering if this problem's roots are the same.
