    Nephele - Local File Server

    Run Nephele WebDAV server to serve local files.


    Follow the steps here to install PAM development libraries for your OS:


    sudo npm install -g nephele-serve


    To serve the current directory.

    sudo nephele-serve .

    To serve users' home directories.

    sudo nephele-serve --home-directories

    To serve user directories under the current directory. This creates directories within the server root with the users' usernames, and serves their own directory to them.

    sudo nephele-serve --user-directories .

    If you want to run it without installing it, you can do that too.

    sudo npx nephele-serve .

    If you want to run it without root, you can do that too, but you must set the port to something higher than 1000, and you'll likely only be able to log in with the user who runs the script.

    nephele-serve -p 8080 .

    Only regular users (UIDs 1000-59999) are allowed to log in.

    Cluster with PM2

    You can load Nephele as a cluster of worker processes using PM2. The following will start a cluster of 8 instances serving users' home directories.

    sudo npm install -g pm2
    sudo pm2 start -i 8 -u root --uid 0 nephele-serve --node-args "--experimental-specifier-resolution=node" -- --home-directories

    Then you can save it and have it load at system startup.

    sudo pm2 save
    sudo pm2 startup systemd

    So, putting it all together, if you:

    • use Ubuntu Server
    • use a Let's Encrypt certificate for TLS
    • want to serve user directories out of a custom folder
    • want to use a cluster of 8 worker processes
    • want to have the server load on startup

    You'd do this (replacing with your domain, and the path at the end with your server root path).

    sudo apt install libpam0g-dev nodejs npm
    sudo npm i -g npm n
    sudo n 16
    sudo npm i -g nephele-serve pm2
    sudo pm2 start -i 8 -u root --uid 0 nephele-serve --node-args "--experimental-specifier-resolution=node" -- --user-directories --cert /etc/letsencrypt/live/ --key /etc/letsencrypt/live/ /path/to/your/data/directory/
    sudo pm2 save
    sudo pm2 startup systemd

    Node Warning

    If you see this warning:

    (node:319632) ExperimentalWarning: The Node.js specifier resolution flag is experimental. It could change or be removed at any time.
    (Use `node --trace-warnings ...` to show where the warning was created)

    Don't worry, it's because the script is using --experimental-specifier-resolution=node to be able to load the PAM authentication module from an ES module.
