Nginx

Used for transferring files to Apache.

Create Directory to Handle Uploaded Files §

sudo mkdir -p /var/www/uploads/SecretUploadDirectory

Change the Owner to www-data §

sudo chown -R www-data:www-data /var/www/uploads/SecretUploadDirectory

Create Nginx Configuration File §

In /etc/nginx/sites-available/upload.conf:

server {
    listen 9001;
 
    location /SecretUploadDirectory/ {
        root /var/www/uploads;
        dav_methods PUT;
    }
}

Symlink our Site to the sites-enabled Directory §

sudo ln -s /etc/nginx/sites-available/upload.conf /etc/nginx//sites-enabled/

Start Nginx §

sudo systemctl restart nginx.service

Error messages can be found in: /var/log/nginx/error.log.

For example:

ss -lnpt | grep '80'

ps -ef | grep '2811'

Could output something like python -m websockify 80 localhost:5901 -D which means there is a module already listening to port 80. To get around we can get rid of the default Nginx configuration:

sudo rm /etc/nginx/sites-enabled/default

And now we test:

curl -T /etc/passwd

tail -1 /var/www/upload/SecretUploadDirectory/users.txt

Then we can navigate to http://localhost/SecretUploadDirectory.
