By default, no DLT data link type conversion will be made. Provide a series of comma deliminated hex values which will beused to rewrite or create the Layer 2 header of the packets.
Takes a pair of comma deliminated ethernet MAC addresses which will replace the source MAC address of outbound packets.
By default, no DLT data link type conversion will be made. This option allows you to send multiple packets at a time, thus allowing for longer sleep times which can be more accurately implemented.
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.
By default, editing Layer 2 addresses will rewrite broadcast and multicast MAC addresses. Higher numbers increase verbosity. This option may appear up to 2 times. 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.
This option may appear up to 1 times. 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. Packets may be truncated during capture if the snaplen is smaller then thepacket. This is how it looks.
This option must appear in combination with the following options: It supports audio playback and record operations. It does the following: Please see the tcpdump 1 man page for a complete list of options. Please see the readme.
Be sure to quote the arguments so that they are not interpreted by tcprewrite. Hence, you should only use this if you know know that your OS provides the FCS when reading raw packets. This feature will detect netmap capable network drivers on Linux and BSD systems. Higher numbers increase verbosity.
These two functions will block the caller until they finish their operation. The first MAC address will be used for the server traffic and the optional second MAC address will be used for the client traffic.
Note that bypassing the network driver will disrupt other applications connected through the test interface.
tcpreplay-edit - Replay network traffic is a tool for replaying network traffic from files saved with tcpdump or other tools which write pcap(3) files.

#Version: 增加了修改VLAN tag内容. * tcprewrite - 简单的说就是修改2层, 3层, 4层报文头部. * tcpreplay - 真正发包, 可以选择主、从网卡, 发包速度等. * tcpbridge - bridge two network segments with the power of tcprewrite 2. 安装指南. You should be able to use tcprewrite to add the VLAN tag (sounds like you already did that) and then send it out the untagged physical interface.
Anyways, I'm not that familiar with the virbr0 interface type, but if it doesn't show up under --listnics then libpcap can't open it for writing packets.
tcprewrite [-flag [value]] [--opt-name Allows you to rewrite ethernet frames to add a q header to standard ethernet headers or remove the q VLAN tag information.
add Rewrites the existing ethernet header as an q VLAN --vlan-tag=number Specify the new q VLAN tag value. This option may appear up to 1. Jun 19, · I tried it and addded VLAN id with tcprewrite (ok), set up a vlan-tagged interface virbr tagged with VLAN id (also ok), then tried tcpreplay to virbr - but no luck.
It says Fatal Error: Invalid interface name/alias: virbr In fact it won't even let me use the buddy virbr0 interface either - it has disappeared from the.Tcprewrite add vlan tag description
