How to Install JSXC on Kali Linux Latest

JSXC is a popular open-source web-based messenger that can be used to chat securely on web applications. In this tutorial, we will be learning how to install JSXC on Kali Linux, the popular security-focused Linux distribution.

Prerequisites

Before we get started, let's make sure that you have the following:

• Kali Linux version up-to-date
• Root access or user account with sudo privileges
• A modern web browser such as Google Chrome or Mozilla Firefox

Step 1: Install Apache server and PHP

First, we need to install Apache web server and PHP dependencies. These two are necessary to run the JSXC web application.

To install, run the following command in the terminal:

sudo apt-get update
sudo apt-get install apache2 php7.4 php7.4-curl php7.4-xml

Step 2: Enable Apache server on startup

After the installation of Apache, we need to enable it to start automatically whenever the system boots up. Type the following command to enable it:

sudo systemctl enable apache2

Step 3: Download JSXC

Navigate to the official JSXC website and download the latest version of JSXC in your home directory by using wget command:

cd ~
wget https://github.com/jsxc/jsxc/archive/master.zip

Step 4: Unzip the downloaded file

Unzip the downloaded JSXC package by using the unzip command:

sudo apt-get install unzip
unzip master.zip

Step 5: Move JSXC files to Apache web directory

Move the JSXC files under the web server directory /var/www/html/. If the directory does not exist, you can create by typing the command:

sudo mkdir /var/www/html/

Then, move the JSXC files to the directory using this command:

sudo mv jsxc-master/* /var/www/html/

Step 6: Set file permission

Apache needs permission to use the files. Type the following command to change it:

sudo chown -R www-data: /var/www/html/
sudo chmod -R 755 /var/www/html/

Step 7: Install and Configure Prosody XMPP Server

JSXC requires an XMPP server to run, and for this tutorial, we will be using Prosody. To install and configure Prosody, follow the instructions from the following tutorial:

Step 8: Configure Prosody for JSXC

Now, it's time to configure Prosody for JSXC. Open the file "/etc/prosody/conf.avail/[YOUR_HOSTNAME].cfg.lua" using a text editor such as nano:

sudo nano /etc/prosody/conf.avail/[YOUR_HOSTNAME].cfg.lua

Add the following configuration at the end of the file:

component "jsxc.[YOUR_HOSTNAME]"
  component_secret = "JSXC_COMPONENT_SECRET"

Remember to replace [YOUR_HOSTNAME] with your hostname and JSXC_COMPONENT_SECRET with a secret passphrase of your choice.

Afterward, save and close the file.

Step 9: Restart Prosody and Apache services

Now that we made the configuration changes to Prosody and Apache web servers, we need to restart the services to apply the changes. To do so, type the following command:

sudo systemctl restart prosody.service apache2.service

Step 10: Open JSXC in your web browser

Finally, it's time to launch JSXC on your web browser by accessing the following URL:

http://[YOUR_HOSTNAME]

Note that replacing [YOUR_HOSTNAME] with your hostname specified in the Prosody configuration file. To use JSXC, you need to create an XMPP account on the server and then log in to the web application.

Congratulations! You have successfully installed and configured JSXC on your Kali Linux machine.
