This is an example how to simple analyze LAN packets using Node.js

Description

I'm using node_pcap library with Node.js and NowJS for data syncing. It's just yet another project just fun and to test interesting technologies.

Installation

You need node, ofc. For OSX users:

brew install node

If you don't have node packet manager:

curl http://npmjs.org/install.sh | sh

Install NowJS (global recommended):

npm install -g nowjs

Install node_pcap (global recommended):

npm install -g node_pcap

Run webserver:

sudo node webserver.js (yes, it requires root privileges)

You may have troubles with env variables because of sudoing, try this:

sudo env NODE_PATH=$NODE_PATH && node webserver.js

Breaks still? Make sure that your NODE_PATH is correct, it should be something like that (with default node installation):

export NODE_PATH=/usr/local/lib/node_modules

node_pcap troubles

Right now, node_pcap library is not compatible with node 0.6.x But I found a minimum workaround (full compatibility pull request going to be merged soon) Go to your node modules:

cd $NODE_PATH // for me
git clone https://github.com/mranney/node_pcap.git

Remove 2 lines from pcap_binding.cc

#include <node_events.h>
#include <ev.h>

Then:

node-wf configure build // build a module

Everything should go fine:

cd build
mkdir default
cp ./Release/* ./default/*
cd ..
mv node_pcap pcap

That's all.

Edit team.js - it contains mac addresses and photos of users that you want to detect.
