 Common Request Headers


=> Host: Some web servers host multiple websites so by providing the host headers you can tell it which one you require, otherwise you'll just receive the default website for the server.


* User-Agent: This is your browser software and version number, telling the web server your browser software helps it format the website properly for your browser and also some elements of HTML, JavaScript and CSS are only available in certain browsers.


* Content-Length: When sending data to a web server such as in a form, the content length tells the web server how much data to expect in the web request. This way the server can ensure it isn't missing any data.


* Accept-Encoding: Tells the web server what types of compression methods the browser supports so the data can be made smaller for transmitting over the internet.


* Cookie: Data sent to the server to help remember your information (see cookies task for more information).

Common Response Headers


Set-Cookie: Information to store which gets sent back to the web server on each request (see cookies task for more information).


Cache-Control: How long to store the content of the response in the browser's cache before it requests it again.


Content-Type: This tells the client what type of data is being returned, i.e., HTML, CSS, JavaScript, Images, PDF, Video, etc. Using the content-type header the browser then knows how to process the data.


Content-Encoding: What method has been used to compress the data to make it smaller when sending it over the internet.

Common Network Commands: Ping

-
Ping Command Overview The `ping` command is a fundamental utility used in network diagnostics. It checks the reachability of a host on an Internet Protocol (IP) network and measures the round-trip time for messages sent from the originating host to a destination computer. The command uses the Internet Control Message Protocol (ICMP) to send echo request packets and listens for echo replies. Origin and Development The `ping` command was developed in 1983 by Mike Muuss as a diagnostic tool for the ARPANET. Since then, it has become a standard utility available on most operating systems, including Linux, Windows, and macOS, making it an essential tool for network administrators and users. Basic Functionality The `ping` command serves several functions: - Tests connectivity to a specified host. - Measures the time taken for packets to travel to the destination and back. - Provides statistics about packet loss and round-trip time. Key Command Syntax 1. Basic Syntax:    ```    ping [options]

Common Network Commands: Route

-
Route Command Overview The route command is a part of the older net-tools package used in Linux systems for viewing and manipulating the IP routing table. It provides information about how packets are routed through the network and allows for the addition, deletion, and modification of routes. Origin and Development Historically, the route command has been a primary tool for managing network routing in Linux. However, it has largely been replaced by the ip command from the iproute2 package, which offers more advanced features and capabilities. Despite this, route is still commonly used in many Linux distributions for its simplicity and familiarity. Basic Functionality The route command serves several functions: - Displays the current routing table entries. - Shows destination networks, gateways, and associated interfaces. - Allows for the addition, deletion, and modification of routes. Key Command Syntax 1. Display Routing Table:    ```    route -n    ```    The -n option prevents DNS

John The Ripper

John the Ripper  Is one of the most well known, well-loved and versatile hash cracking tools out there. It combines a fast cracking speed, with an extraordinary range of compatible hash types. This room will assume no previous knowledge, so we must first cover some basic terms and concepts before we move into practical hash cracking. A hash is a way of taking a piece of data of any length and  representing it in another form that is a fixed length. This masks the original value of the data. This is done by running the original data through a hashing algorithm. There are many popular hashing algorithms, such as MD4,MD5, SHA1 and NTLM. Lets try and show this with an example: If we take "polo", a string of 4 characters- and run it through an MD5 hashing algorithm, we end up with an output of: b53759f3ce692de7aff1b5779d3964da a standard 32 character MD5 hash. Likewise, if we take "polomints", a string of 9 characters- and run it through the same MD5 hashing algorithm, w
