C++ Packet Injector

I couldn’t find any other C++ Packet Injector anywhere on the net. So I decided to code one myself. This was modified from the previous C Injector. I like this because of NO PROMISCUOUS MODE NEEDED!! Also, the htons was a tricky mofo to beat in g++ but, ALAS! It was done. Copy and paste with your favorite editor into a file called start.cpp from the command line compile with:

bt#: g++ -o start start.cpp

then run the injector with:

bt#:./start "Interface ID" "# of packets"

exit the program with CTRL-C
