Usage

Configuration

All configuration options are accepted either as arguments or can be placed in an ini-style file as such:

maxsize = 4294967296
allowhotlink = true
# etc

...and then invoke linx-server -config path/to/config.ini

Options

• -bind 127.0.0.1:8080 -- what to bind to (default is 127.0.0.1:8080)
• -sitename myLinx -- the site name displayed on top (default is inferred from Host header)
• -siteurl "http://mylinx.example.org/" -- the site url (default is inferred from execution context)
• -filespath files/" -- Path to store uploads (default is files/)
• -metapath meta/ -- Path to store information about uploads (default is meta/)
• -maxsize 4294967296 -- maximum upload file size in bytes (default 4GB)
• -maxexpiry 86400 -- maximum expiration time in seconds (default is 0, which is no expiry)
• -allowhotlink -- Allow file hotlinking
• -contentsecuritypolicy "..." -- Content-Security-Policy header for pages (default is "default-src 'self'; img-src 'self' data:; style-src 'self' 'unsafe-inline'; frame-ancestors 'self'; referrer origin;")
• -filecontentsecuritypolicy "..." -- Content-Security-Policy header for files (default is "default-src 'none'; img-src 'self'; object-src 'self'; media-src 'self'; style-src 'self' 'unsafe-inline'; frame-ancestors 'self'; referrer origin;")
• -xframeoptions "..." -- X-Frame-Options header (default is "SAMEORIGIN")
• -remoteuploads -- (optionally) enable remote uploads (/upload?url=https://...)
• -nologs -- (optionally) disable request logs in stdout
• -googleapikey -- (optionally) API Key for Google's URL Shortener. (How to create one)

SSL with built-in server

• -certfile path/to/your.crt -- Path to the ssl certificate (required if you want to use the https server)
• -keyfile path/to/your.key -- Path to the ssl key (required if you want to use the https server)

Use with http proxy

• -realip -- let linx-server know you (nginx, etc) are providing the X-Real-IP and/or X-Forwarded-For headers.

Use with fastcgi

• -fastcgi -- serve through fastcgi

Require API Keys for uploads

• -authfile path/to/authfile -- (optionally) require authorization for upload/delete by providing a newline-separated file of scrypted auth keys
• -remoteauthfile path/to/remoteauthfile -- (optionally) require authorization for remote uploads by providing a newline-separated file of scrypted auth keys

A helper utility linx-genkey is provided which hashes keys to the format required in the auth files.

Deployment

Linx-server supports being deployed in a subdirectory (ie. example.com/mylinx/) as well as on its own (example.com/).

1. Using fastcgi

A suggested deployment is running nginx in front of linx-server serving through fastcgi. This allows you to have nginx handle the TLS termination for example.
An example configuration:

server {
    ...
    server_name yourlinx.example.org;
    ...
    
    client_max_body_size 4096M;
    location / {
        fastcgi_pass 127.0.0.1:8080;
        include fastcgi_params;
    }
}

And run linx-server with the -fastcgi option.

2. Using the built-in https server

Run linx-server with the -certfile path/to/cert.file and -keyfile path/to/key.file options.

3. Using the built-in http server

Run linx-server normally.

4. Using Docker with the built-in http server

First, build the image: docker build -t linx-server .

You'll need some directories for the persistent storage. For the purposes of this example, we will use /media/meta and /media/files.

Then, run it: docker run -p 8080:8080 -v /media/meta:/data/meta -v /media/files:/data/files linx-server
