If you manage multiple VPS nodes and offer SMTP services selectively to clients, automating the management of IP sets can save significant effort. In this guide, we’ll walk through how we automated the synchronization of SMTP-enabled IPs across over 100 VPS nodes.
This tutorial has been tested and is fully operational on Virtualizor-based KVM VPS nodes. The script is configured to run at 1-hour intervals by default, but you can adjust the interval depending on your requirements and available resources. It can be set up on a separate server, on the same server as WHMCS, or another VPS. If using the WHMCS server, ensure it is properly secured, as this script has access to all your servers.
Prerequisites
Python 3.x installed on your system.
Required Python libraries:
pip install paramiko pandas
WHMCS with VPS product configurations.
SSH access to all VPS nodes and the WHMCS server.
ipset installed and configured on each VPS node.
Proper iptables rules set up on all VPS nodes (detailed below).
Required iptables and ipset Configuration on VPS Nodes
To manage SMTP access effectively, you need the following iptables and ipset rules configured on all VPS nodes. These rules must also persist across reboots:
modprobe br_netfilter
ipset create allowed_ips hash:ip
iptables -F
iptables -P FORWARD DROP
iptables -I FORWARD -m set --match-set allowed_ips src -o viifbr0 -p tcp --dport 25 -j ACCEPT
iptables -I FORWARD -m set --match-set allowed_ips dst -o viifbr0 -p tcp --dport 25 -j ACCEPT
iptables -A FORWARD -o viifbr0 -p tcp --dport 25 -j REJECT
iptables -A FORWARD -o viifbr0 -j ACCEPT
service iptables save
These rules ensure that SMTP traffic is blocked by default unless explicitly allowed via ipset. Ensure the rules are applied on every reboot of the VPS nodes.
Overview of the Solution
Fetch VPS Configuration from WHMCS: Retrieve a JSON file listing VPS configurations, including SMTP-enabled status and associated IPs.
Process Data: Parse the JSON file to extract primary and additional IPs for SMTP-enabled VPSs.
Sync IP Sets Across Nodes: Use ipset to update allowed IPs for SMTP on each node. This includes adding or removing IPs as needed.
Parallel Execution: Speed up the process by handling multiple nodes concurrently with Python threading.
Implementation
1. Create the Excel File for Node Information
The Python script uses an Excel file to identify the SSH IPs and ports of all VPS nodes. Create an Excel file in the following format:
IP Address
SSH Port
192.168.1.100
22
192.168.1.101
2222
Save this file as securecrt_servers.xlsx and ensure it is accessible to the script.

Docker is a game-changing tool for developers and system administrators. It allows you to package and run applications in isolated containers, making deployment and management seamless. Pairing Docker with a Virtual Private Server (VPS) creates a powerful environment for hosting scalable and efficient applications. This guide will help beginners get started with Docker on a VPS.
What is Docker?
Docker is a platform that uses containerization to run applications and their dependencies in a lightweight, portable environment. Containers are isolated from one another, ensuring that software runs consistently regardless of the hosting infrastructure.
Why Use Docker on a VPS?
Efficient Resource Usage: Containers use less system resources than virtual machines.
Consistency: Ensures your application works the same way across different environments.
Scalability: Easy to scale applications by running multiple containers.
Portability: Move containers between development, staging, and production with ease.
Step-by-Step Guide to Using Docker on a VPS
Step 1: Set Up Your VPS
Before installing Docker, ensure your VPS is ready.
Log in to Your VPS:
ssh username@your_server_ip
Update Your VPS: Keep your system packages updated.
sudo apt update && sudo apt upgrade -y
Step 2: Install Docker
Docker provides installation scripts for Linux distributions like Ubuntu, CentOS, and Debian.
Install Docker on Ubuntu/Debian: Run the following commands:
Pull a Docker Image: Docker uses images to create containers. Pull the official NGINX image:
docker pull nginx
Run the Container: Start a container using the NGINX image:
docker run -d -p 80:80 nginx
This maps your VPS’s port 80 to the container’s port 80, making the NGINX web server accessible in your browser.
Verify It’s Running: Visit http://your_server_ip in your browser. You should see the NGINX welcome page.
Step 4: Manage Docker Containers
Get comfortable managing containers using Docker commands:
List Running Containers:
docker ps
Stop a Container:
docker stop container_id
Remove a Container:
docker rm container_id
List All Containers (Running and Stopped):
docker ps -a
Step 5: Deploy Applications with Docker
Docker makes deploying complex applications easy.
Create a Dockerfile: A Dockerfile specifies how a container is built. Example for a Python app:
FROM python:3.8-slim
WORKDIR /app
COPY . /app
RUN pip install -r requirements.txt
CMD ["python", "app.py"]
Build the Docker Image:
docker build -t my-python-app .
Run the Application:
docker run -d -p 5000:5000 my-python-app
This makes your application accessible at http://your_server_ip:5000.
Best Practices for Using Docker on VPS
Use Docker Compose for Multi-Container Applications: Define your services in a docker-compose.yml file and bring them up with:
docker-compose up -d
Monitor and Clean Up Resources: Docker can consume disk space quickly. Periodically clean up unused images and containers:
docker system prune -a
Use Private Repositories for Sensitive Images: Store proprietary Docker images securely on private registries like Docker Hub or GitHub Packages.
Backup Data: Use Docker volumes to persist data and regularly back up critical information.
Conclusion
Docker on a VPS unlocks powerful hosting capabilities, making it easier to deploy, manage, and scale applications. With the steps outlined in this guide, you can get started with Docker and take full advantage of its features.
At Hosteons, we offer robust VPS hosting optimized for Docker, ensuring smooth performance and scalability. Explore our plans and launch your Docker-powered applications today.

In an era where digital communication is a lifeline, securing your WhatsApp account is more important than ever. With over 2 billion users globally, WhatsApp is a popular target for hackers and cybercriminals. Protecting your account ensures your personal chats, media, and private information remain safe from prying eyes. At Hosteons, we understand the importance of security in the digital age. Here’s a guide to help you secure your WhatsApp account effectively.
1. Enable Two-Step Verification
Two-step verification adds an extra layer of security to your WhatsApp account by requiring a PIN in addition to your phone number.
How to enable:
Open WhatsApp and go to Settings.
Navigate to Account > Two-Step Verification.
Tap Enable, set a six-digit PIN, and add a recovery email address.
This ensures that even if someone gets access to your SIM card, they cannot access your WhatsApp account without the PIN.
2. Protect Your SIM Card
Your WhatsApp account is tied to your phone number, so securing your SIM card is crucial.
Use a SIM lock to prevent unauthorized access.
Avoid sharing your mobile number publicly or on untrusted platforms.
Consider enabling a SIM PIN from your phone’s settings to add another layer of protection.
3. Avoid Clicking on Suspicious Links
Phishing scams are a common tactic used by hackers to steal WhatsApp accounts.
Never click on links from unknown sources, especially if they promise rewards, gifts, or lottery winnings.
Verify the sender’s identity before engaging with any link.
4. Regularly Check Active Sessions
WhatsApp Web is a convenient feature, but it can also be a security risk if left open on shared devices.
How to check:
Go to Settings > Linked Devices.
Review all active sessions and log out of any device you don’t recognize.
This ensures no one is secretly accessing your account from another device.
5. Be Cautious with Verification Codes
Verification codes are key to accessing your WhatsApp account.
Never share your verification code with anyone, even if they claim to be from WhatsApp support.
WhatsApp will never ask for your verification code via messages or calls.
6. Keep Your App Updated
Regular updates ensure your app is protected from the latest vulnerabilities and threats.
Enable automatic updates on your device to ensure you’re always running the latest version of WhatsApp.
7. Use End-to-End Encryption
WhatsApp provides end-to-end encryption by default, ensuring that your messages and calls remain private.
To verify encryption for specific chats, open the chat, tap the contact’s name, and check the Encryption section.
Avoid third-party apps that claim to enhance WhatsApp functionality, as they can compromise your data.
8. Educate Yourself About Common Scams
Be aware of common WhatsApp scams, such as:
Impersonation scams where hackers pretend to be someone you know.
“Friend in distress” scams, where hackers claim your friend is in trouble and ask for money.
Fake technical support calls claiming to be from WhatsApp.
Always verify any unusual request or message before responding.
9. Backup Wisely
While backups are essential, they can also be a vulnerability if not secured.
Use encrypted backups when storing your chats on Google Drive or iCloud.
Avoid storing backups on shared or untrusted devices.
10. Monitor for Suspicious Activity
If you notice any unusual activity on your WhatsApp account, such as missing chats or unfamiliar messages, act immediately:
Log out of all devices from Linked Devices.
Re-enable two-step verification and update your PIN.
Contact WhatsApp support if you suspect your account has been compromised.
Conclusion
Securing your WhatsApp account is not just about protecting your conversations; it’s about safeguarding your privacy and digital identity. By implementing these measures, you can enjoy the convenience of WhatsApp without compromising your security.
At Hosteons, we prioritize your digital safety, whether you’re managing your hosting account or your personal apps. For more tips on staying secure in the digital world, stay tuned to our blog.
