How to Monitor VPS Resource Usage Like a Pro

hosteons July 20, 2025 July 20, 2025 Leave a Comment

Whether you’re running a website, application, or a private service, keeping an eye on your VPS (Virtual Private Server) is crucial. Poor resource monitoring can lead to downtime, sluggish performance, or even security issues. In this guide, we’ll walk you through the best tools and techniques to monitor your VPS resource usage like a seasoned sysadmin.

Why VPS Monitoring Matters

When you rent a VPS, you’re allocated limited resources like:

CPU
RAM
Disk space
Network bandwidth

If any of these are overused or misconfigured, your entire server performance can degrade — affecting uptime and user experience. Real-time monitoring helps prevent:

Unexpected crashes
Performance bottlenecks
Security breaches (like DDoS or crypto mining)
Exceeding bandwidth quotas

Key VPS Metrics to Monitor

CPU UsageHigh CPU usage over time may signal bad code, a process gone rogue, or even a hacked server.
Memory (RAM) UsageRunning out of RAM can cause your apps to crash or your OS to start swapping.
Disk I/O and SpaceIf disk space fills up, backups fail, logs get lost, and the server might even crash. Also watch for high I/O which can slow everything down.
Network TrafficMonitor both inbound and outbound traffic. Spikes could mean viral traffic — or an attack.
Load AverageGives you a quick look at how stressed your system is overall, especially on Linux.

Tools to Monitor VPS Resources

Here are some tools — from basic to advanced — to help you monitor effectively:

🛠️ Basic Linux Commands (Good for SSH Users)

top or htop – Real-time CPU, memory, and process monitoring
free -m – RAM usage
df -h – Disk usage
iotop – Disk I/O monitoring
nload, vnstat – Network bandwidth tracking
uptime – Load average

📊 Web-Based Monitoring Tools

Netdata – Beautiful, real-time dashboards for CPU, RAM, Disk, Network, and more.
Glances (with Web UI) – A terminal-based tool with optional web dashboard.
Cockpit – Lightweight admin panel for basic server monitoring and control.
Grafana + Prometheus – Powerful combo for enterprise-grade, customizable monitoring.

🔔 Alerts and Uptime Monitoring

UptimeRobot / BetterUptime – Alert you when your server goes down.
Monit – Local monitoring tool that can also auto-restart services if they crash.
Zabbix / Nagios – Enterprise-level solutions with alerting and distributed monitoring.

Automate and Optimize Monitoring

Set Threshold Alerts – Get notified when CPU hits 90% or disk drops below 10% space.
Use Crontabs for Logs – Automate scripts to log and analyze stats daily.
Centralize Logs – Use tools like Logwatch or Logrotate to keep logs manageable and secure.

Security Tip

If you notice sudden CPU or network spikes, investigate immediately. Could be malware, brute-force attacks, or unauthorized scripts.

Final Thoughts

You don’t need to be a DevOps engineer to monitor your VPS like a pro. Start with basic Linux commands, move to visual dashboards like Netdata, and eventually automate your monitoring with alerting systems.

Regular monitoring saves time, money, and the reputation of your services. Don’t wait for an outage to start caring — make it part of your server maintenance habit today.

Top 5 Tips to Harden Your Linux VPS Against Attacks in 2025

hosteons June 24, 2025 Leave a Comment

In 2025, cyberattacks are more sophisticated than ever. Whether you’re hosting a personal project or critical business application, securing your Linux VPS is no longer optional—it’s essential. Thankfully, with just a few steps, you can drastically reduce your risk and keep your VPS locked down against the most common threats.

At Hosteons, we provide high-performance KVM VPS with root access, but security is a shared responsibility. Here’s how you can harden your VPS in minutes:

1. Use SSH Keys Instead of Passwords

Disable password login and use SSH key authentication for more secure, automated, and brute-force-resistant logins.

Steps:

Generate a key pair using ssh-keygen
Upload your public key to your VPS: ~/.ssh/authorized_keys
Disable password auth in /etc/ssh/sshd_config

👉 Read: Why You Should Use SSH Keys Instead of Passwords

2. Set Up a Firewall (UFW/iptables)

Block unnecessary ports to reduce your attack surface. Only open what’s required (e.g., 22 for SSH, 80/443 for web).

Example with UFW:

sudo ufw default deny incoming
sudo ufw allow 22
sudo ufw allow 80
sudo ufw allow 443
sudo ufw enable

3. Install and Configure Fail2Ban

Prevent brute-force attacks by banning IPs with too many failed login attempts.

Install Fail2Ban:

sudo apt install fail2ban

Create a jail for SSH and monitor logs like /var/log/auth.log or /var/log/secure.

👉 Full Fail2Ban Guide

4. Keep the System and Software Updated

Always run the latest security patches. Use tools like unattended-upgrades for automated updates.

How to Set Up a Private Proxy Server on Your KVM VPS

hosteons June 21, 2025 Leave a Comment

Setting up a private proxy server on your KVM VPS is a great way to enhance privacy, control internet access, or bypass geo-restrictions. In this tutorial, we’ll guide you through the process of installing and configuring a private HTTP/HTTPS proxy server using Squid — a powerful, flexible, and widely-used caching proxy.

✅

Prerequisites

A KVM VPS from Hosteons
Root access to your VPS
Ubuntu 20.04/22.04 or CentOS/AlmaLinux 8/9 installed

🔧

Step-by-Step Setup Using Squid Proxy

Step 1: Update System Packages

# For Ubuntu/Debian
sudo apt update && sudo apt upgrade -y

# For CentOS/AlmaLinux
sudo dnf update -y

Step 2: Install Squid

# Ubuntu/Debian
sudo apt install squid -y

# CentOS/AlmaLinux
sudo dnf install squid -y

Step 3: Backup Default Config

sudo cp /etc/squid/squid.conf /etc/squid/squid.conf.backup

Step 4: Configure Squid

Edit the config:

sudo nano /etc/squid/squid.conf

Look for and modify these lines:

http_port 3128

Add this at the top or near ACL section to allow only your IP:

acl allowed_ips src YOUR_IP_HERE
http_access allow allowed_ips
http_access deny all

Replace YOUR_IP_HERE with your real IP. You can get it from https://ipinfo.io

Step 5: Restart Squid

# Ubuntu/Debian
sudo systemctl restart squid

# CentOS/AlmaLinux
sudo systemctl restart squid

Step 6: Enable on Boot

sudo systemctl enable squid

🔍

Step 7: Test Your Proxy

Configure your browser or tool to use your VPS IP and port 3128 as the HTTP/HTTPS proxy. You can use websites like https://whatismyipaddress.com to verify your outgoing IP.

🔐

(Optional) Add Authentication to Your Proxy

To prevent misuse, you can add basic authentication.

Install Apache utils:

sudo apt install apache2-utils -y  # Ubuntu/Debian
sudo dnf install httpd-tools -y   # CentOS/AlmaLinux

Create password file and user:

sudo htpasswd -c /etc/squid/passwd proxyuser

Edit squid.conf and add:

auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/passwd
auth_param basic realm Proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Restart Squid again.

✅

Done!

How to Monitor Login Attempts and File Changes on Your VPS

hosteons June 11, 2025 Leave a Comment

When you manage your own VPS, keeping it secure goes far beyond setting up a strong password or using SSH keys. One of the most important — and often overlooked — tasks is monitoring login attempts and file changes.

If someone tries to brute-force their way into your server or modifies system files without authorization, you need to know immediately. In this post, we’ll walk you through simple tools and methods to keep an eye on your VPS security 24/7.

🔍 Why Monitoring Matters

Cyberattacks aren’t always obvious. Hackers often:

Try to gain access via repeated failed logins
Modify configuration files to install backdoors
Inject malicious code into websites or scripts
Use rootkits to hide their presence

By monitoring login attempts and file changes, you can detect suspicious activity early and prevent damage before it escalates.

🛡️ Monitor Login Attempts with

Fail2Ban

✅ What It Does:

Fail2Ban scans your log files (like /var/log/auth.log) and bans IPs that show signs of malicious behavior, such as too many failed login attempts.

🔧 How to Install:

sudo apt update && sudo apt install fail2ban -y

📂 Basic Configuration:

The main config file is located at:

/etc/fail2ban/jail.local

A sample rule to monitor SSH:

[sshd]
enabled = true
port = ssh
filter = sshd
logpath = /var/log/auth.log
maxretry = 3

Fail2Ban automatically updates your firewall to block suspicious IPs.

🗂️ Monitor File Changes with

AIDE

(Advanced Intrusion Detection Environment)

✅ What It Does:

AIDE scans the file system and creates a baseline. It then alerts you when files are modified, added, or deleted.

🔧 How to Install:

sudo apt install aide -y

🛠️ Initialize the Database:

sudo aideinit
sudo cp /var/lib/aide/aide.db.new /var/lib/aide/aide.db

📊 Run Regular Checks:

sudo aide --check

For automation, schedule this via cron and configure it to email alerts.

🔁 Real-Time File Monitoring with

inotify-tools

For lightweight, real-time file monitoring (e.g., for specific web directories), use inotify-tools.

🔧 Install:

sudo apt install inotify-tools -y

Example: Watch for changes in

/var/www/html

:

inotifywait -m -r /var/www/html

This tool is great for developers and sysadmins wanting immediate feedback on file activity.

✉️ Optional: Email Alerts for Login & File Events

Combine these tools with email notifications or integrate them with your external monitoring system (Zabbix, Prometheus, or even a simple bash + mail setup) for real-time alerting.

🧠 Best Practices

🔐 Use SSH keys instead of passwords
🔒 Disable root login via SSH
🚫 Change default SSH port
📉 Monitor logs daily or automate alerting
🧾 Keep audit trails and backups

💡 All Hosteons VPS & VDS Plans Support These Tools

Whether you’re using a Budget KVM VPS, Ryzen KVM VPS, or Ryzen 7950X VDS, all of these monitoring tools can be installed and configured quickly.

We offer full root access and support popular Linux distributions like Ubuntu, Debian, AlmaLinux, and CentOS — perfect for custom security setups.

🔒 Secure Your VPS Before It’s Too Late

Don’t wait until something goes wrong. Set up login and file monitoring today — and stay in control of your VPS.

Why You Should Use SSH Keys Instead of Passwords on Your VPS

hosteons June 7, 2025 Leave a Comment

When managing your VPS or Virtual Dedicated Server (VDS), security should always come first. While many users rely on traditional passwords for remote access, SSH keys offer a far more secure and convenient alternative.

At Hosteons, we strongly recommend using SSH key authentication to secure your VPS access — and here’s why.

🔐 What Are SSH Keys?

SSH (Secure Shell) keys are a pair of cryptographic keys used to authenticate with a remote server:

Public Key: Stored on your VPS (e.g., in ~/.ssh/authorized_keys)
Private Key: Stored securely on your local device (e.g., ~/.ssh/id_rsa)

When you try to connect, your device proves ownership of the private key — no need to transmit a password.

🚫 The Problem with Passwords

Easily guessed or brute-forced
Often reused across multiple accounts
Susceptible to phishing or keylogging
Require manual entry each time

If your password is weak or exposed, your server is vulnerable.

✅ Benefits of Using SSH Keys

1. Stronger Security

SSH keys are typically 2048-bit or 4096-bit, which are practically uncrackable by brute force.

2. No Password Transmission

No password is sent over the network, making it immune to interception.

3. Convenience

You can set up password-less login using your key, often combined with an SSH agent or passphrase.

4. Script-Friendly

Automated deployments and Git-based workflows rely on SSH keys for secure, non-interactive authentication.

5. Block Brute-Force Attacks

Once password authentication is disabled, bots and attackers can no longer guess credentials.

🛠️ How to Set Up SSH Key Authentication

Generate a Key Pair (on your local machine):

ssh-keygen -t rsa -b 4096

Upload the Public Key to Your VPS:

ssh-copy-id user@your-vps-ip

Or manually place the public key into ~/.ssh/authorized_keys
Disable Password Authentication:Edit /etc/ssh/sshd_config on your VPS:

PasswordAuthentication no

Then restart the SSH service:

systemctl restart sshd

🔒 Combine with Fail2Ban and Firewall

For maximum protection:

Use Fail2Ban to block repeated failed login attempts
Limit access to port 22 using UFW or CSF firewall
Change the default SSH port (optional)

🧠 Summary

Using SSH keys instead of passwords is one of the simplest yet most powerful steps you can take to secure your VPS or VDS.

At Hosteons, all our KVM VPS, Ryzen VPS, and Ryzen 7950X VDS plans support full SSH key authentication out of the box.

Take 2 minutes to set it up — and save yourself from countless security headaches.
