How do I install Tcpreplay on Linux?
In order to use tcpreplay , you first need to capture live network traffic using packet capture tools such as tcpdump, rewrite TCP/IP packet headers of the captured packets appropriately (usually MAC and IP addresses), and then re-inject the packets on to any arbitrary network under consideration.
How do I run Tcpreplay on Linux?
First, install tcpreplay and tcpdump on your Linux system. To install tcpreplay , follow the instructions in this tutorial. The next step is to capture live network traffic, and dump it to a pcap file. To do so, run tcpdump command as follows.
Does Tcpreplay allow packet injection?
When tcpreplay sends packets, it injects them between the TCP/IP stack of the system and the device driver of the network card. The result is the TCP/IP stack system running tcpreplay never sees the packets.
How do I play a pcap file?
To replay your own packet capture data, simply add any number of files containing libpcap formatted packet capture data to /opt/pcap-replay. The files must end with the . pcap extension. To pick up newly installed files, simply restart the service.
What is Tcpreplay used for?
Tcpreplay is a suite of free Open Source utilities for editing and replaying previously captured network traffic. Originally designed to replay malicious traffic patterns to Intrusion Detection/Prevention Systems, it has seen many evolutions including capabilities to replay to web servers.

| # tcpreplay -i eth0 sample.pcap | replay a given pcap as it was captured |
|---|---|
| #tcpreplay –loop=0 -i eth0 sample.pcap | To replay the sample.pcap forever or until CTRL-C is pressed |
What are pcap files?
What is a PCAP file? PCAP files are data files created using a program. These files contain packet data of a network and are used to analyze the network characteristics. They also contribute to controlling the network traffic and determining network status.

How do I replay TCP Traffic?
How to record and replay TCP traffic
- Record TCP traffic with tcpdump to pcap file.
- View captured traffic tcpdump -qns 0 -X -r app-traffic.pcap.
- Edit source IP so that it’s on your own network.
- Replay traffic with tcplivereplay from recorded pcap file (note step #3)
How do I replay PCAP with Tcpreplay?
What is PCAP playback?
This project enables packet capture data to be replayed through a network interface to simulate live network traffic. This can be used to support functional, performance, and load testing of Apache Metron.
How do I view pcap files in Wireshark?
Wireshark can read in previously saved capture files. To read them, simply select the File → Open menu or toolbar item. Wireshark will then pop up the “File Open” dialog box, which is discussed in more detail in Section 5.2.
Can Wireshark replay pcap?
q=replay+pcap Note wireshark provides several commandline programs that can select, split, combine, and alter the contents of pcap files so you could replay data partly the same as but partly different from what was captured.
What is the Tcpreplay command?
Description. This manual page briefly documents the tcpreplay command. The basic operation of tcpreplay is to resend all packets from the input file(s) at the speed at which they were recorded, or a specified data rate, up to as fast as the hardware is capable.
