## Prompt
|
|
Packet sniffers are programs that intercept the network traffic flowing in and out of a system through network interfaces. Packet sniffers can be coded by either using sockets API provided by the kernel, or by using some packet capture libraries. Write a program and implement your own packet sniffer in your programming language of choice.
|
|
|
|
## Installation
|
|
This script is made with Python 3.8 and uses the `argparse` library, and [scapy](https://scapy.net/), a program for packet manipulation. Ensure that you have [Python 3.8+](https://www.python.org/downloads/) and these dependencies installed in order to run this script correctly.
|
|
|
|
## Usage
|
|
First, clone this repository to your machine. Open the command line on your machine and navigate to where you cloned this repository. To get help using `cd`, use [this tutorial](https://swcarpentry.github.io/shell-novice/02-filedir/index.html).
|
|
|
|
This script needs sudo or administrative privileges to run. The script will run explicitly until you kill it using either `CTRL+C` or closing the terminal window.
|
|
|
|
Run the script with the following (on UNIX-based systems):
|
|
|
|
~~~
|
|
$ sudo -E env PATH="$PATH" python index.py
|
|
