# Quick Start

## Starting the server

On the server, run the following

```bash
$ python3 -m venv .example 
$ activate .example/bin/activate

$ python3 NetGenieSrv.py
```

This opens three sockets:

1. The bridge socket that listens for the phone to connect to.
2. An ``incoming'' socket to read packets sent from the device to the server
3. An ``outgoing'' socket to write packets from the server to the device.

On the phone, connect to the server and port specified by the `-B` and `-b` arguments.

This can be specified by changing the source code or using the following command-line
arguments:

```bash
$ python3 NetGenieSrv.py  -h
usage: NetGenieSrv.py [-h] [-B BRIDGE_IP] [-b BRIDGE_PORT] [-I IOIP] [-i INCOMING_PORT] [-o OUTGOING_PORT]

options:
  -h, --help            show this help message and exit
  -B BRIDGE_IP, --bridge_ip BRIDGE_IP
                        The IP that listens for NetGenie mobile app client connections.
  -b BRIDGE_PORT, --bridge_port BRIDGE_PORT
                        The port that listens for NetGenie mobile app client connections.
  -I IOIP, --ioip IOIP  The IP that listens on the server for connections from whoever is debugging the phone.
  -i INCOMING_PORT, --incoming_port INCOMING_PORT
                        The port that the person debugging will read packets from the device.
  -o OUTGOING_PORT, --outgoing_port OUTGOING_PORT
                        The port that the person debugging will write packets to the device.
```

## Using the server

```bash
$ ipython3

import NetGenieSrv as ngs
from scapy.all import *
ip = IP(src='10.10.20.1', dst='255.255.4.20')
tcp = TCP(sport=8080, dport=8443)
pkt = ip/tcp
a = pkt.build()

insock, outsock = ngs.connectIO()
pktIn = insock.read(40) # Read a packet send from the phone
outsock.send(a) # Send a packet to the NetGenie client.

```
