Which is best tool for network traffic dumping, reading the same and again sending it back to the network



I had an application (basically a server) that has to accept large amount of data filled in different2 structures from multiple clients for UDP packets.I want to dump this data in such a format that is easy to read back from that file and again send it back to the server, ( I MAY SAY A RECORD AND REPLAY TYPE MODULE).

Which tool is suitable for do the same and also that run in the backgound along in the application

thanks in advance, monz

One Answer:


You can capture the traffic with tcpdump, dumpcap or tshark/wireshark (which in fact also use dumpcap). As a replay tool you could use bittwist, tcpreplay, or maybe ostinato, see
