If you’re running OpenWRT on a router with limited internal storage, using a USB external drive (like an SSD or flash drive) as the main software installation path can be a lifesaver. This guide walks you through using Extroot to mount external storage for installing packages and storing data — even after a reboot.
✅ Step-by-Step: Setting Up USB Drive as Software Storage on OpenWRT
🔄 1. Update the Package List
Before doing anything, log in to your router via SSH (using tools like PuTTY or Terminal), and update the available package list:
📦 2. Install Required USB and Filesystem Support Packages
Since OpenWRT often resets packages on reboot, make sure to (re)install all required packages:
🔍 3. Check If Your USB Drive Is Detected
Run the following commands:
You should see something like
/dev/sda1
(for swap) and/dev/sda2
(main storage). If you don’t, try unplugging and replugging the drive.💽 4. Format the Drive (If Needed)
If
/dev/sda2
isn’t formatted properly, format it with ext4:⚠️ Warning: This will erase all existing data on
/dev/sda2
.📁 5. Mount the USB Drive Manually
Create a directory and mount the drive:
Now verify it:
You should see
/dev/sda2
mounted on/mnt/sda2
.📤 6. Copy Existing System Data to the SSD
Copy the overlay data to your SSD:
This step ensures that your system data moves to the SSD.
⚙️ 7. Configure Extroot in
/etc/config/fstab
Tell OpenWRT to use the USB SSD as the overlay (installation path) on boot:
🔁 8. Reboot and Verify
Now, reboot your router:
After the reboot, run:
You should now see
/overlay
mounted on/dev/sda2
— congratulations, your OpenWRT router is now using the USB drive as the main storage!👨🔧 Final Tips

It seems like the EHCP (Easy Hosting Control Panel) service is not installed properly or there might be an issue with its systemd service unit. Let’s troubleshoot the problem step by step:
1. Check EHCP Installation:
Make sure EHCP is installed correctly on your system. Check the installation logs or any error messages during the installation process.
2. Check EHCP Service Unit:
Verify if the EHCP service unit file exists in the systemd directory. It seems that the service unit file is missing, which is causing the “Unit ehcp.service not found” error.
ls /etc/systemd/system/ehcp.service
If the file is missing, you may need to reinstall EHCP or manually create the service unit file.
3. Reinstall EHCP:
If EHCP is not installed correctly, you may want to reinstall it. Follow the installation instructions provided by the EHCP documentation or the source from which you downloaded it.
4. Create EHCP Service Unit File:
If the service unit file is missing, you can create it manually. Create a file named `ehcp.service` in the `/etc/systemd/system/` directory. Here’s an example:
plaintext
[Unit]
Description=EHCP Service
[Service]
ExecStart=/path/to/ehcp/startup/script
[Install]
WantedBy=default.target
Replace `/path/to/ehcp/startup/script` with the actual path to the EHCP startup script.
5. Reload systemd and Start EHCP:
After creating or verifying the service unit file, reload systemd and try starting the EHCP service again.
sudo systemctl daemon-reload
sudo systemctl start ehcp
Check the status:
sudo systemctl status ehcp
If there are any errors, they should be displayed in the status output, helping you diagnose the issue.
Remember to replace placeholder paths and commands with the actual ones used in your EHCP installation. If you encounter specific error messages during these steps, please provide them, so I can offer more targeted assistance.

When turning your PC into a server using EHCP (Easy Hosting Control Panel), you have two options for hosting your website:
1. **Using a Domain You Already Own:**
– If you already own a domain, you can configure the DNS settings of your domain to point to your server’s IP address. This way, visitors can access your website using your existing domain.
2. **Using a Subdomain Provided by EHCP:**
– EHCP typically allows you to create subdomains based on the domain associated with your server’s IP address. For example, if your server’s IP is 1.2.3.4, EHCP might offer subdomains like `subdomain1.1.2.3.4` or similar.
– You can use these subdomains to host your websites without purchasing a separate domain.
**Important Considerations:**
– Using a custom domain looks more professional and is easier for visitors to remember.
– Purchasing a domain is relatively inexpensive and provides you with more control over your online identity.
– If you choose the subdomain option, the URL might be longer and less memorable.
In summary, while you can host a website using EHCP without purchasing a domain, it’s often recommended to use a custom domain for a more professional and user-friendly experience. If you don’t already own a domain, consider registering one to enhance your online presence.
