Installing SFTPGo on Kali Linux

In this tutorial, we will guide you through the process of installing SFTPGo on Kali Linux.

Prerequisites

Before we begin, ensure that you have the following:

Kali Linux installed
Root access to the system
A web browser and an internet connection

Step 1 - Downloading SFTPGo

To download SFTPGo, we need to clone the repository from Github.

Open the terminal.
Run the following command to install Git, if it is not already installed:
```
sudo apt-get install git
```

Clone the SFTPGo repository:

git clone https://github.com/drakkan/sftpgo.git

Step 2 - Installing Dependencies

SFTPGo requires some dependencies to be installed before we can run it. To install these dependencies, run the following commands:

sudo apt-get update
sudo apt-get install -y build-essential
sudo apt-get install -y libssl-dev
sudo apt-get install -y libffi-dev
sudo apt-get install -y python3-dev
sudo apt-get install -y python3-pip

Step 3 - Setting Up a Virtual Environment

We will create a virtual environment to run SFTPGo in. This will help to ensure that all dependencies are isolated from the system and make it easier to manage.

Install the virtualenv package by running the following command:
```
sudo apt-get install python3-virtualenv
```

Create a new virtual environment:

virtualenv --python=python3 /opt/sftpgo_env

Activate the virtual environment:
```
source /opt/sftpgo_env/bin/activate
```

Step 4 - Installing SFTPGo

Change to the directory where SFTPGo was cloned:
```
cd sftpgo
```
Run the following command to install SFTPGo:
```
pip3 install -r requirements.txt
```
This will install all the required dependencies for SFTPGo.

Step 5 - Configuring SFTPGo

Copy the config.json.sample file to config.json:
```
cp config.json.sample config.json
```
Edit the config.json file to suit your needs. You can specify the listening address and port, create users, and define global and per-user settings.

Step 6 - Running SFTPGo

Activate the virtual environment:
```
source /opt/sftpgo_env/bin/activate
```
Change to the sftpgo directory:
```
cd sftpgo
```
Run the following command to start SFTPGo:
```
python3 -m sftpgo --config=config.json
```
This will start the SFTP server and listen for incoming connections.

Conclusion

In this tutorial, we have shown you how to install SFTPGo on Kali Linux. With SFTPGo installed and configured, you can now securely transfer files between your system and remote clients.
