DOWNLOAD TCPREPLAY TOOL

Each netblock pair is evaluated in order against the IP addresses. By default, -n and -l are used. Automatically enabled for packets modified with --seed , --pnat , --endpoints or --fixlen. Enable caching of packets to internal memory. However, occasionally, tools will store more bytes then told to. Override source ethernet MAC addresses.

tcpreplay(1) - Linux man page

Allows you to rewrite ethernet frames to add a The value of number is constrained to being:. Loop through the capture file X times. Print nothing except the statistics at the end of the run. Bad things may happen if you specify this option.

Save the option state to rcfile. Takes a pair of comma deliminated ethernet MAC addresses which will replace the source MAC address of outbound packets. In that case, the file ". This option must appear in combination with the following options: Any tcprepplay that is not marked as not presettable may be preset by loading values from configuration "RC" or ".

Packets may be truncated tcprepplay capture if the snaplen is smaller then the packet. 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.

Since the randomization is deterministic based on the seed, you can reuse the same tdpreplay value to recreate the traffic. Specify a floating point value for the Mbps rate that tcpreplay should send packets at. Preloading can be used with or without --loop and implies --enable-file-cache. Some operating systems by default do not allow for forging source MAC addresses. This option must not appear in combination with any of the following options: This option may appear up to 1 times.

This option may tcprepkay up to 2 times. If tcprepkay IP address in the packet matches the first netblock, it is rewriten using the second netblock as a mask against the high order bits.

Please see the tcpdump 1 man page for a complete list of options. Reduce the amount of time to sleep by specified usec.

For support please use the tcpreplay-users lists. Automatically enabled for packets modified with --seed--pnat tcpreplat, --endpoints or --fixlen. Description This manual page briefly documents the tcpreplay command. Override output DLT encapsulation. For more details, please see the Tcpreplay Manual at: When enabling verbose mode -v you may also specify one or more additional arguments to pass to tcpdump to modify the way packets are decoded.

Takes a comma delimited series of colon delimited CIDR netblock pairs. By default, tcpreplay will send packets based on the size of the "snaplen" stored in the pcap file which is usually the correct thing to do. By specifying this option, tcpreplay will ignore the snaplen field and instead try to send packets based on the original packet length.

This option allows you to send multiple packets at a time, thus allowing for longer sleep times which can be more accurately implemented.

Limit the number of packets to send. Specify a list of comma delimited port mappingings consisting of colon hcpreplay port number pairs.

Pad or truncate packet data to match header length.
