How to Monitor All SSH Connections Through Discord? 🚀🌟

Imagine having a digital watchdog that keeps an eye on SSH connections to your server, alerting you on Discord every time someone logs in. Sounds cool, right? Let’s set this up and add an extra layer of awareness to your server's security !

🕵️ Step 1: Summon Your Discord Webhook

Before we unleash the magic, we need to create a Discord webhook. Think of it as recruiting a digital messenger.

Enlist Your Messenger

1. Dive into Discord: Choose your preferred updates channel, and hit Edit channel > Integrations.
2. Webhook Initiation: New to webhooks? Click Create Webhook. If you're a veteran, select View Webhooks then New Webhook.
3. Craft an Identity: Give your webhook a catchy name and an avatar.
4. Secure the Communications: Copy the WEBHOOK URL; it’s the key to your direct line.
5. Save the Day: Make sure to hit Save.

🚀 Step 2: Dive into Your Server

Gear up for some command-line action. SSH into your server to start setting up our digital watchdog.

🌟 Step 3: The Spellbook - Create a Script

Now, we're crafting a spell in the form of a script named ssh-check.sh.

The Incantation

#!/bin/bash

# Your secret communication line
DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/XXXXXXXXXX/XXXXXXXXXXXXXXXX"

# Detect the intruder... I mean, the guest
IP=$(echo $SSH_CLIENT | awk '{print $1}')
curl -H "Content-Type: application/json" -X POST -d "{\"content\": \"SSH connection from IP: $IP\"}" "$DISCORD_WEBHOOK_URL"

Unlock the Code: Swap in your unique webhook URL here.

This enchantment alerts you with the IP address of every connecting soul.

⭐ Step 4: Awaken the Spell

Give life to your script, making it a vigilant guardian:

sudo chmod +x ./ssh-check.sh

🎥 Step 5: The Guardian's Post - Modify SSH Config

Let’s ensure our guardian watches over every entrance:

vim /etc/ssh/sshd_config

📝 Feel free to use your favorite text editor. If vim feels like ancient runes, try nano.

Whisper this at the file’s end:

ForceCommand /path/to/ssh-check.sh && /bin/bash

⚠️ WARINING ! If you dont have bash, setup correctly the path to your shell, otherwise you will not be able to connect to your shell with ssh

❤️ Step 6: Awaken the Guardian

Revive the SSH service to embrace the new guardian:

systemctl restart sshd

🚪 I advise you to NOT close your current connection right now ! Try to connect to your server with another terminal first to ensure everything work.

🌍 Step 7: Revel in Your Fortress

Congratulations! You’ve transformed your server into a digital fortress, with alerts for every SSH connection sent straight to your Discord. Your server is not just secured; it’s connected.
