To enable OpenWrt to automatically restore a previous backup during the first reboot after flashing, you can integrate the backup file and the restore script into the firmware during the build process. Here’s how to do it: 1. Create the files Directory In the root directory of your OpenWrt source tree, create a directory named files. Any files placed in this directory will be directly copied into the final firmware with the same directory structure. mkdir -p ~/openwrt/files 2. Add the Backup File and Script 2.1 Place the Backup File Copy the backup file you’ve prepared (e.g., backup.tar.gz) into the files/etc/backup/ directory: mkdir -p ~/openwrt/files/etc/backup cp /path/to/your/backup.tar.gz ~/openwrt/files/etc/backup/ Replace /path/to/your/backup.tar.gz with the actual path to your backup file. 2.2 Add the Auto-Restore Script Create an auto-restore script and place it in the files/etc/init.d/ directory, for example, named restore_backup: mkdir -p ~/openwrt/files/etc/init.d nano ~/openwrt/files/etc/init.d/restore_backup In the editor, add the following script content: #!/bin/sh # Define the backup file path BACKUP_FILE="/etc/backup/backup.tar.gz" # Check if the backup file exists if [ -f "$BACKUP_FILE" ]; then # Restore the…

the Nginx configuration and explanation for allowing external access only to the /report directory on an internal server, while blocking access to other directories: Configuration Example server { listen 80; server_name your-domain.com; # Allow access only to the /report directory location /report { proxy_pass http://192.168.1.1; # Replace with the actual internal server address proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; # Optional: Handle path rewriting if needed rewrite ^/report(/.*)?$ $1 break; } # Deny access to other paths location / { deny all; } # Handle other path requests if necessary # You can add additional location blocks for specific path requests } Explanation Allowing Access to /report: The location /report block forwards requests to the internal server http://192.168.1.1. The rewrite directive (optional) handles path rewriting to ensure that the /report prefix is not added to the internal server's request path. Denying Access to Other Paths: The location / block with the deny all; directive blocks access to all other paths. This means that external users will receive a 403…
