/ Home server, remote access / By

Introduction:

Managing a server remotely is essential for flexibility and convenience. ZeroTier simplifies this by creating a secure virtual network that connects your devices as if they were on the same local network. In this guide, we’ll show you how to install and configure ZeroTier on a Debian Linux server, enabling remote access from your phone. With just a few steps, you’ll gain secure, on-the-go control over your server.

1. Update the Debian Server

  • Before starting, ensure your server is up-to-date:
sudo apt-get update
sudo apt-get upgrade

2. Install ZeroTier on Debian

  • This command installs ZeroTier directly from the official repository and starts the ZeroTier service.
curl -s https://install.zerotier.com | sudo bash

3. Join a ZeroTier Network

  • To join a ZeroTier network, use the following command:
sudo zerotier-cli join <Network-ID>
  • Replace <Network-ID> with the unique ID of your ZeroTier network, which you can create or obtain from my.zerotier.com.

4. Authorize the Server on the Network

  • Log in to your ZeroTier account and navigate to the “Networks” tab.
  • Under the Members section, find your Debian serverโ€™s ZeroTier address (displayed when you joined the network).
  • Click the “Auth?” checkbox next to your server’s address to authorize it on the network.

5. Configure Firewall (Optional)

  • If you have a firewall configured, ensure it allows traffic through the ZeroTier network interface:
sudo ufw allow in on zt0
sudo ufw allow out on zt0
  • Replace zt0 with your ZeroTier network interface name if different.

6. Install ZeroTier on Your Phone

  • For Android/iOS:
    • Download and install the ZeroTier app from the Google Play Store or App Store.
    • Open the app and join the same network using the Network ID.

7. Authorize Your Phone on the Network

  • Just like with the server, go to my.zerotier.com, find your phone in the Members section, and authorize it by checking the “Auth?” box.

8. Test the Connection

  • With both your Debian server and phone connected to the same ZeroTier network, test connectivity by pinging the server’s ZeroTier IP address from your phone:
ping <Server-ZeroTier-IP>

9.Conclusion

  • Setting up ZeroTier on a Debian Linux server is straightforward and provides a secure, private network that you can access from anywhere with your phone. This setup is perfect for remote management, file access, or any scenario where you need secure connectivity on the go.
