Bad things may happen if you specify this option. This option must appear in combination with the following options: Make sure you have enough free RAM to store the entire pcap file s in memory or the system will swap and performance will suffer.
Higher numbers increase verbosity. Takes a pair of comma deliminated ethernet MAC addresses which will replace the source MAC address of outbound packets.
The following arguments are valid: The default string for this option is: Specify a floating point value for the Mbps rate that tcpreplay should send packets at. The default number for this option is: These two functions will block the caller until they finish their operation.
Note that this ratio is based on the random number genereated by the supplied fuzz seed. To change the DLT type of the output pcap, select tcprewrite add vlan tag description of the following values: 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.
Allows you to rewrite ethernet MAC addresses of packets. Alternatively, you can specify a maximum number of packets to send.
By default, -n and -l are used. This option must not appear in combination with any of the following options: Specify a floating point value to modify the packet replay speed.
To change the DLT type of the output pcap, select one of the following values: Secondary traffic is usually server-to-client or outbound TX on khial virtual interfaces. Please see the tcpdump 1 man page for a complete list of options. This feature will detect netmap capable network drivers on Linux and BSD systems.
If you captured network traffic using a network tap, then you can end up with two pcap files- one for each direction. Automatically enabled for packets modified with --seed, --pnat, --endpoints or --fixlen.
Tcprewrite is a tool to rewrite packets stored in pcap 3 file format, such as crated by tools such as tcpdump 1 and ethereal 1. The flow feature will track and print statistics of the flows being sent.
Allows you to step through one or more packets at a time. Provide a series of comma deliminated hex values which will be used to rewrite or create the Layer 2 header of the packets.
Higher numbers increase verbosity. Replaying captured traffic may simulate odd or broken conditions on your network and cause all sorts of problems. This option must appear in combination with the following options: User can replace these functions with other functions that access other types of media or devices MMCSD for example.
The default string for this option is: 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. The first MAC address will be used for the server to client traffic and the optional second MAC address will be used for the client to server traffic.
The shell provides some basic commands to manipulate the content of the attached USB disk drive. Provide a series of comma deliminated hex values which will be used to rewrite or create the Layer 2 header of the packets. The first instance of this argument will rewrite both server and client traffic, but if this argument is specified a second time, it will be used for the client traffic.
For more details, please see the Tcpreplay Manual at: This option may appear up to 2 times. A flow is loosely defined as a unique combination of a 5-tuple, i. By default, no DLT data link type conversion will be made.
