change Webmin Port – Webmin is a powerful web-based interface for managing Unix-like systems, offering administrators an easy way to control their server settings. By default, Webmin runs on port 10101, but for security reasons or to avoid conflicts with other services, you might want to change this port. In this tutorial, we’ll guide you step by step on how to change the default Webmin port number using Terminal or SSH.

Why Change the Webmin Port?
Changing the default port for Webmin is recommended for several reasons:
- Enhanced security: Using a non-standard port helps reduce the chances of automated attacks on your server.
- Port conflict avoidance: If another service on your server is using port 10101, switching Webmin to a different port can prevent potential conflicts.
- Customization: Personalizing your Webmin setup can streamline your workflow and network configurations.
Prerequisites
- SSH access to your server (using a terminal or an SSH client like PuTTY).
- Root or sudo privileges.
- Webmin installed and running.
Step-by-Step Guide to Change Webmin Port
Follow these steps to change the default Webmin port:
1. Connect to Your Server via SSH
You’ll need to log into your server (purchased from vpswebhostingindia) using SSH. For Windows users, use an SSH client like PuTTY.
2. Navigate to Webmin Configuration File
Webmin’s configuration file is typically located at /etc/webmin/miniserv.conf. You can open and edit this file using a text editor like nano or vi. Let’s use nano for this example:
vi /etc/webmin/miniserv.conf
3. Modify the Port Number
Once you have the configuration file open, look for the line that starts with port=10101. This specifies the port number Webmin is currently using. Change the port number to the desired value (e.g., port=30555).

After Changing:
4. Save the Changes
If you’re using vi, save the file by pressing esc :wq and hit Enter
or
nano, save the file by pressing CTRL + O and hit Enter, then exit the editor by pressing CTRL + X.
5. Restart Webmin Service
To apply the changes, you’ll need to restart the Webmin service. Use the following command to restart it:
sudo systemctl restart webmin
Alternatively, on older systems or if systemctl doesn’t work, you can use:
/etc/init.d/webmin restart
6. Access Webmin on the New Port
Now, Webmin should be accessible on the new port. Open your browser and go to:
http://your-server-ip:new-port
For example, if you changed the port to 30555:
http://your-server-ip:30555
Make sure to replace your-server-ip with your actual server’s IP address and new-port with the port you configured.
7. Verify the Change
After accessing Webmin on the new port, verify that everything is functioning correctly by logging into the Webmin interface. If the connection fails, check your firewall rules and make sure the Webmin service restarted successfully.
Conclusion
Changing the default Webmin port (change webmin port) is a simple yet effective way to enhance your server’s security and prevent potential port conflicts. By following the steps above, you can quickly modify the Webmin port using SSH and adjust your server’s settings accordingly. Remember to always document the changes you make to avoid confusion down the road and ensure your firewall rules are properly configured to allow access on the new port.
Now that you’ve secured Webmin by changing its port, you can enjoy safer server management!
