How Do I Find the OS of My Web Server?


Angela Bailey

Are you curious about the operating system (OS) running on your web server? Finding out the OS of your web server is a straightforward process that can be done using a variety of methods. In this article, we will explore different techniques to help you discover the OS powering your web server.

Using Ping

If you have access to the command line, one way to determine the OS is by using the ping command. Open your command prompt or terminal and type:


Replace “” with your actual website domain. After hitting enter, you will see a response from the server.

Look for a line that mentions “TTL” (Time-To-Live). The TTL value’s interpretation varies based on the OS:

  • Windows: If the TTL value is around 32, 64, or 128, it indicates that the server is running a Windows operating system.
  • Linux/Unix: If the TTL value is around 255, it suggests that the server is likely running a Linux or Unix-based operating system.

Note that this method provides an indication rather than definitive proof of the web server’s OS.

Banner Grabbing

Banner grabbing involves examining specific information sent by a web server when establishing a connection. This technique can provide insights into both the web server software and sometimes even its underlying operating system.

You can perform banner grabbing using various tools like Telnet or specialized security scanners. Here’s an example using Telnet:

  1. Open your command prompt or terminal.
  2. Type: telnet 80 and hit enter.
  3. If the connection is successful, you will see a blank screen.
  4. Type: HEAD / HTTP/1.0 and press enter twice.
  5. The server’s response will appear on the screen. Look for lines starting with “Server:” or “X-Powered-By:” to identify the web server software.

While the web server software can give hints about the underlying OS, it’s important to note that this method is not always accurate.

Using Online Services

If you prefer a more user-friendly approach, several online services can help you identify the OS of your web server. These services typically perform various checks and analysis of your website’s server response headers to provide accurate results.

Some popular online services include:

Using these services is as simple as entering your website’s domain name and letting them do the rest. They will present you with detailed information about your web server, including its operating system.

In Conclusion

Finding out the operating system of your web server can be done using various methods such as ping, banner grabbing, or relying on online services. Each technique has its own advantages and limitations, and it’s recommended to use multiple approaches for a more accurate analysis.

Remember, identifying the web server’s operating system can be helpful for troubleshooting, security assessments, or simply satisfying your curiosity about the technology powering your website.
