How to send pcap file packets on NIC?

Question

I have some network traffic captured pcap file and want to send its packets on NIC; is it possible? Is there any application to do this?

Probably highly dependant on the OS. You should indicate which one. — bortzmeyer, Dec 23 '09 at 20:43

You should be able to use some kind of replay application like tcpreplay.

bit-twist can do this.

just install it and inject your packet like this :

I use tcpreplay on Linux/Freebsd eg:

#tcpreplay -l 0 -i eth1 path-to-your-captured-file.pcap

-l loop how many times, 0 for infinite
-i interface where you want to send out

Yes there is a way - sending a packet to NIC means injecting it to an interface.

You can do this with the help of libnet packege in linux. I myself am working on the same these days. Try Googling with this term, you'll surely get some good stuff to share.
