Tips to packet different network frame

Some usefull tools for playing network frame

Some tools can send pcap file packets on NIC

tcpreplay

# 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

bittwist

# bittwist -i eth0 pcap-file.pcap 

playcap

The tool can play back Wireshark, tcpdump, and libpcap captures.
Maybe too old.
