drateR-go

drateR is a simple SFTP (Secure File Transfer Protocol) server implemented in Go. It provides a secure way to upload and download files using the SFTP protocol over SSH.

Features

• Secure File Transfers: Utilizes SSH for encrypted file transfers.
• Basic Authentication: Uses a plain text password stored in an environment variable for authentication.
• Customizable Directory: Configurable directory for storing uploaded files.

Prerequisites

• Go 1.16 or higher
• SSH private key for authentication
• Environment variables for configuration

Directory Structure

src/
│
├── drateR.go
└── files/

• drateR.go: The main Go script for running the SFTP server.
• files/: Directory where uploaded files will be stored.

Download

First, clone the repository to your local machine:

git clone https://github.com/zeusssz/drateR.git
cd drateR/src

Setup

1. Install Go Packages

Make sure you have the required Go packages installed:

go get github.com/pkg/sftp
go get golang.org/x/crypto/ssh

2. Generate SSH Key Pair

Generate an SSH key pair if you don't already have one:

ssh-keygen -t rsa -b 2048 -f id_rsa -N ""

• id_rsa: Your private key.
• id_rsa.pub: Your public key (not needed in this script but required for SSH setup).

3. Set Up Environment Variables

Set the SFTP_PASSWORD environment variable with your chosen password:

export SFTP_PASSWORD="your_password"

4. Configure Private Key Path

Ensure the privateKeyPath constant in drateR.go is set to the path of your private key:

privateKeyPath = "id_rsa" // Path to the private key for authentication

5. Run the Server

Navigate to the src directory and run the server:

cd src
go run drateR.go

The server will start listening on port 2022 by default.

Usage

Connecting to the Server

You can connect to the SFTP server using any SFTP client. Here are a few examples:

Using Command Line

sftp -P 2022 user@<IP_ADDRESS_OF_SERVER>

Replace <IP_ADDRESS_OF_SERVER> with the IP address of the machine running the SFTP server. Use the password you set in the SFTP_PASSWORD environment variable when prompted.

Using PuTTY’s psftp (Windows)

1. Download PuTTY from PuTTY Download Page.

2. Open psftp and connect:

   psftp -P 2022 user@<IP_ADDRESS_OF_SERVER>

3. Enter the password when prompted.

Configuration

• Port: The server listens on port 2022 by default. Modify the port constant in drateR.go to change this.
• Root Directory: The directory where files are stored is specified by rootDir. Change it if needed.

Troubleshooting

• Failed to Connect: Ensure that the server is running and the port is open. Verify the private key path and permissions.
• Authentication Issues: Double-check the environment variable SFTP_PASSWORD for correct password value and spelling.
