Fragroute Overview As of Tcpreplay 3. Since the randomization is deterministic based on the seed, you can reuse the same seed value to recreate the traffic. Pad the packets with 0x AC and the server is This can obviously cause problems later on when you try replaying the traffic.

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.

Allows you to step through one or more packets at a time. 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.

Hence, you should only use this if you know know that your OS provides the FCS when reading raw packets. Preloading can be used with or without --loop and implies --enable-file-cache. 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.

Enable advanced evasion techniques using the built-in fragroute 8 engine.

The value of number is constrained to being: Automatically enabled for packets modified with --seed, --pnat, --endpoints or --fixlen. Please see the tcpdump 1 man page for a complete list of options.

When IP addresses are randomized, it is done in a deterministic manner, based on the seed value you provide, so that sessions between two hosts are maintained.

Optionally, the traffic can be split between two interfaces, written to files, filtered and edited in various ways, providing the means to test firewalls, NIDS and other network devices. The value of number is constrained to being: Depending on the device type that will be processing the traffic, the application data may or may not be important, but having a full packet may be.

It allows you to map IP addresses in one subnet to IP addresses in another subnet.

However, occasionally, tools will store more bytes then told to. Packets may be truncated during capture if the snaplen is smaller then the packet.

Using different seed values results in different values for the IP addresses for the same input pcap.The Ethernet plugin allows you to control the source and destination MAC addresses. Additionaly, you can add, remove and edit q VLAN tag headers.

tcprewrite also allows you to add or remove q VLAN tag information from ethernet frames. currently it only supports non-VLAN tagged ethernet frames (DLT_EN10MB). tcprewrite from tcpreplay can do this. You need to overwride the output format to Ethernet II, and supply the source MAC and dest MAC which the.

This option may appear up to 1 times. Allows you to rewrite ethernet frames to add a q header to standard ethernet. -Font]tcprewrite [-Font]-flags]] Override destination ethernet MAC addresses.

This option may appear up to 1 times. Allows you to rewrite ethernet frames to add a q header to standard ethernet headers or remove the q VLAN tag information. I need to read a PCAP file, modify some fields (actually IPv4 source and destination and Ethernet source and destination). The PCAP is pre-filtered to only include IPv4 over Ethernet packets.
