Simple Guard Server

Simple Guard Server is a security script designed to monitor SSH connections to a VPS and send notifications to a Discord channel when a new connection is established. The script also restricts SSH access during specific hours.

Features

• Discord Notifications: Sends a message to a specified Discord channel when a new SSH connection is made.
• IP Logging: Logs the IP address of the user and the VPS.
• Time-based SSH Access: Automatically restricts SSH access during non-working hours (00:00 - 08:00 according to the Europe/Moscow time zone).

Installation Guide

Prerequisites

1. VPS: You need a VPS with SSH access.
2. Discord Webhook: Create a webhook in your Discord server and note the URL.
3. Role ID: Note the role ID of the role you want to mention.

1. Clone the Repository

   git clone https://github.com/yume-real/simple-guard-server/
   cd Simple-Guard-Server

2. Configure the Script

   Edit the script simple-guard-server.sh and replace YOUR_WEBHOOK_URL and YOUR_ROLE_ID with your actual Discord webhook URL and role ID:

   discord_webhook_url="YOUR_WEBHOOK_URL"
   role_id="YOUR_ROLE_ID"

3. Ensure Required Tools are Installed

   ./connects_monitor.sh

Running as a Service (Optional)

To run the script as a service and ensure it starts on boot, you can create a systemd service unit:

1. Create Service Unit File

   sudo nano /etc/systemd/system/connects_monitor.service

2. Add the Following Content

   [Unit]
   Description=Simple Guard Server
   
   [Service]
   ExecStart=/path/to/your/connects_monitor.sh
   Restart=always
   User=root
   
   [Install]
   WantedBy=multi-user.target

   Make sure to replace /path/to/your/connects_monitor.sh with the actual path to your script.

3. Enable and Start the Service

   sudo systemctl daemon-reload
   sudo systemctl enable connects_monitor
   sudo systemctl start connects_monitor

4. Check Service Status

   Verify that the service is running with:

   sudo systemctl status connects_monitor

Usage

The script continuously monitors SSH connections. When a new connection is detected, it sends a message to the specified Discord channel with the connection details, including the time, username, user's IP address, and the VPS IP address. The script also adjusts SSH access permissions according to the specified time rules.
