Launch

Start

Create as many servers as wanted by providing different type, host, port and other arguments!

• for security reasons, next server prevents any access to the hidden files (started with dot)
• also, clients can't access any data out the root path, that defined on server startup

Startup example:

php src/server.php type=nex host=127.0.0.1 port=1900 root=/target/dir

• host and port - optional arguments, read Arguments documentation for details!

Arguments

Default argument values depending of server protocol selected.

Some arguments also defined in default.json file. Do not change this file without understanding, use CLI instead!

CLI

Provide wanted arguments separated by space, in key=value format

Required

• type - server protocol, also auto-defines default port, supported options:
  • nex - NEX Protocol
• root - absolute path to the public directory, where browser navigation starting from

Optional

• host - default is 127.0.0.1 e.g. localhost connections only
• port - default value depends of server type selected, for example 1900 for nex or 1965 for gemini
• file - index file name that server try to open on directory path requested, disabled by default
• list - show content listing in the requested directory (when index file not found), enabled by default
• time - show file modification time as the alt text in directory listing (useful for gemfeed), disabled by default
• fail - absolute path to the failure template (e.g. /path/to/error.gmi), disabled by default
• dump - enable or disable server debug feature, enabled by default
