#Shuriken

A little Python script that allows the capture & combination of upstream and downstream traffic from Great Scott's Throwing Star LAN Tap.

As the LAN tap captures the upstream and downstream traffic seperately this is just a convience script that capture data from two network interafces simultaneously and then combines all the captured data into a single PCAP for subsequent analysis.

##Usage

From the command line just call:

python shuriken.py <iface_up> <iface_down> <pcap_name>

Where iface_up is the local NIC that is connected to the LAN taps upstream interface, iface_down is the local NIC that is connected to the LAN tap's downstream interface, and pcap_name is the name of the combined PCAP file to write out.

To stop an ongoing capture and dump the data to PCAP just press Ctrl-C.

NOTE: To successfully run tcpdump you will likely need to be root.

##Requirements

Shuriken relies on tcpdump and the associated mergecap utility to do it's thing, without them it is useless.

##License Shuriken is released under the LGPL.
