Question 1

How to Connect to Your Windows Server (RDP)

Accepted Answer

You can connect to your Windows Server using Remote Desktop Protocol (RDP) from a Windows PC, macOS, or even a mobile device.

💻 Method 1 — From a Windows Computer

Step 1 — Open Remote Desktop Connection

Click the Start menu (Windows icon in the bottom-left corner).
Type Remote Desktop Connection and press Enter.

Step 2 — Configure the Connection

In the window that appears, enter your server's IP address in the "Computer" field.
Click Connect.
Enter your login credentials (they were sent to you by email).
If you see a certificate warning, click Yes — this is normal for new servers.

Step 3 — You’re Connected

🎉 That’s it! You’re now connected to your server. You can use it just like a regular Windows desktop.

🍎 Method 2 — From macOS

macOS doesn't include a native RDP client, but Microsoft offers an official app.

Download Microsoft Remote Desktop from the Mac App Store.
Open the app and click + Add PC.
In the PC Name, enter your server’s IP address.
Under User Account, click "Add User Account" and fill in your username and password.
Double-click the saved PC to connect.
Accept the certificate warning if prompted.

✅ You're now connected to your server via macOS.

📱 Method 3 — From a Mobile Device (iOS or Android)

You can also connect from your phone or tablet using the official *

Question 2

How to Verify Your Location with Traceroute?

Accepted Answer

Have you noticed that GeoIP websites sometimes show the wrong location for your server or IP address? That’s completely normal — and here’s why.

GeoIP is a technology that estimates your location based on your IP address. It’s useful, but not always reliable. In this guide, we’ll explain how GeoIP works, why the results may vary, and how to trace your actual network path using the `traceroute` tool.

🧠 How Does GeoIP Work?

GeoIP services rely on multiple data sources to associate IP addresses with locations. These include:

1️⃣ WHOIS Data

WHOIS is a public database with details about IP address ownership.
GeoIP providers often extract location info from it.
⚠️ However, the address shown might be that of the ISP or company, not the actual device location.

2️⃣ Regional Internet Registries (RIRs)

There are 5 global registries: ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC.
They assign IP blocks based on region — which helps indicate general location.
This doesn't always reflect where the IP is currently being used.

3️⃣ User-Contributed Data

Some providers accept feedback from users about incorrect locations.
This crowdsourced info improves accuracy over time — but it’s not always consistent.

4️⃣ Third-Party APIs & Data Aggregators

Many services pull from GPS data, mobile apps, ISPs, and commercial sources.

- Still, no method guarantees 100% accuracy.

❗ Can You Trust GeoIP Results?

Not entirely. These t

Question 3

How to Connect to Your Linux Server (SSH)

Accepted Answer

You can access your Linux server from Windows using two simple methods: either with the built-in Command Prompt or using the PuTTY SSH client.

⚡ Method 1 — Using Windows Command Prompt (CMD)

Windows has a built-in SSH client you can use directly from the terminal — no extra software needed.

Press Windows + R, type cmd, then hit Enter.
In the terminal window, type the following command:

ssh root@your.server.ip -p your_port

📝 Replace:

your.server.ip with the IP address of your server
your_port with the correct SSH port (default is usually 22)

Press Enter.
You’ll be asked to enter your SSH password — paste it and press Enter (nothing will show while typing, it's normal).

✅ Done! You’re now connected to your server via CMD.

🪟 Method 2 — Using PuTTY

PuTTY is a lightweight and trusted SSH tool.

Download PuTTY here
Open PuTTY.
In the Host Name (or IP address) field, enter your server IP.
Set the Port to your server’s SSH port (default: 22).
Click Open. You’ll see a terminal window asking for your login: login as:
Enter your username ( root by default) and press Enter.
Right-click to paste your SSH password (copied from your email), then press Enter again.

🎉 You’re connected!

|| If you're having trouble with either method, make sure your login details are correct and that your server is online. S

Question 4

How to Configure DNS on Windows Server

Accepted Answer

If your browser says “No network” or “No internet”, but your server is connected, the issue might be simple: no DNS is configured.

This is common on fresh Windows Server installs. Here’s how to fix it in just a few clicks.

🪟 Step-by-Step — Set DNS Manually

This method works on Windows Server 2012, 2016, 2019, and 2022.

Press Windows + R, type ncpa.cpl, then press Enter. → This opens the list of network adapters.
Right-click your network adapter (usually called Ethernet) and select Properties.
In the list, double-click on:

Internet Protocol Version 4 (TCP/IPv4)

In the new window:

Select Use the following DNS server addresses.
Enter the DNS servers of your choice:

Preferred DNS server:     1.1.1.1
Alternate DNS server:     8.8.8.8

👉 These are fast and reliable public DNS servers from Cloudflare and Google.

Click OK, then Close.

✅ DNS is now configured — your internet access should work in browsers and apps.

🧪 Optional — Check with Command Prompt

To test if DNS is working, open Command Prompt and type:

ping google.com

✅ If you see replies, DNS is working!

❌ If not, double-check the DNS entries above.

💡 Why This Happens

On some Windows Server versions or clean installs:

The system doesn't auto-assign DNS servers
This leads to internet errors in browsers like “no network” or “can’t find address”

Manually setting DNS usually solves the issu

Question 5

How to Check if a Port is Open (and How to Open It)

Accepted Answer

When a service isn’t reachable, checking if the correct port is open and listening is one of the first things to do. In this guide, we’ll show you how to:

Test if a port is open using telnet or other tools
Understand the role of listening services

- Open a port on Windows or Linux

🧠 Before You Start: What Does “Open Port” Really Mean?

A port is considered "open" if:

It's not blocked by a firewall
A program is actively listening on that port

If no software is bound to the port, or if a firewall blocks it, it will appear closed, even if technically available.

🧪 How to Test if a Port is Open

📟 Method 1 — Using Telnet

Telnet is a simple way to test if a port responds.

On Windows or Linux:

telnet your.server.ip port

✅ If the port is open and a service is listening, the screen will go blank or show a banner.
❌ If not, you’ll see a connection error like “Connection refused” or “Could not open connection”.

🧪 Example:

telnet 192.168.1.100 22

🛠 Method 2 — Using Netcat (Linux)

If telnet isn’t available, you can use nc (Netcat):

nc -vz your.server.ip port

✅ You’ll see a success message if the port is open.

❌ Otherwise, it will time out or be refused.

🌐 Method 3 — Online Port Check Tools

You can also use an online port checker like:

https://portchecker.co
https://yougetsignal.com/tools/open-ports

⚠ These tools only work if the port is ope

Question 6

Why don't I have all the bandwidth?

Accepted Answer

If you're wondering why your network isn’t delivering the full 10Gbps or 20Gbps you expected, you're not alone. There are many reasons a speed test might show lower results — and they’re not always related to your server or hosting provider.

In this guide, we’ll break down the most common reasons behind limited bandwidth results and how to test your connection the right way.

1️⃣ The Speed Test Tool Makes a Difference

Not all speed testing tools are built to handle high-speed connections.

Sites like speedtest.net were originally made for home internet testing — usually under 1Gbps.
Many test servers on these platforms can’t handle 10Gbps+ traffic, even if your server can.

🧠 Tip: Use dedicated tools or well-known test servers that support high throughput, such as `iperf3`.

2️⃣ Server Performance Can Be the Bottleneck

Your connection is only as fast as the server you're testing against.

CPU, disk I/O, or system overheads may limit actual transfer speeds.
Single-threaded downloads (e.g., from a browser or wget) rarely reach full bandwidth.

🧠 Tip: Use multi-threaded benchmarking tools like `iperf3` to better measure actual network capability.

3️⃣ How You Test = What You See

The method you use to test bandwidth can have a huge impact.

A single connection often fails to saturate a fast line.
Most browsers and simple tools don’t open enough parallel streams.

🧪 Try This: Use tools that allow multiple th
