      • filter hidden context (started with dot)
      • sort order settings (currently dir first, asc)
    • custom index file name
    • custom failure template
    • custom data directory location
  • KevaCoin storage browser
  • Dynamic application
  • Reverse proxy
  • Stream server

Install

Environment

apt install git composer php-fpm php-mbstring

Stable

Project under development, use repository version!

Repository

• git clone https://github.com/YGGverse/next.git
• cd next - navigate into the project directory
• composer update - grab latest dependencies

Launch

Start

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

• for security reasons, file 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 host=127.0.0.1 port=1900 type=nex mode=fs root=/target/dir

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

Arguments

Optional arguments auto-defined by server protocol type selected

Some arguments also defined in default.json - do not change it without understanding, use CLI instead!

CLI

Provide arguments in key=value format, separated by space

Children nodes dependent of parent arguments defined and would be skipped in other combinations!

Following list explains key dependencies and it value options (started with =)

• type - required, server protocol, also auto-defines default port, supported options:
  • = nex - NEX Protocol
    • mode - optional, server implementation variant, fs (filesystem) by default
      • = fs - static files hosting for the root location
        • root - absolute path to the public directory, where browser navigation starting from
        • file - file name that server try to open on directory path requested, disabled by default
        • list - show listing in directory requested (on index file not found), enabled by default
        • date - show file modification date (as gemfeed) in directory listing, disabled by default
      • = kevacoin - KevaCoin storage browser by RPC connection to the wallet (see kevacoin.conf)
        • rpcscheme - required, for example http
        • rpcport - required, default is 9992
        • rpchost - required, remote or localhost
        • rpcuser - required
        • rpcpassword - required
        • namespace - required, remote or local namespace for data listing (started with N)
• host - optional, default is 127.0.0.1 e.g. localhost connections only
• port - optional, default value depends of server type selected e.g. 1900 for nex or 1965 for gemini
• fail - optional, absolute path to the failure template (e.g. /path/to/error.gmi), disabled by default
• dump - optional, enable or disable server debug feature, enabled by default

Autostart

systemd

Following example mean you have next server installed into home directory of next user (useradd -m next)

# /etc/systemd/system/next.service

[Unit]
After=network.target

[Service]
Type=simple
User=next
Group=next
ExecStart=/usr/bin/php /home/next/next/src/server.php type=nex mode=fs root=/home/next/public
StandardOutput=file:/home/next/debug.log
StandardError=file:/home/next/error.log
Restart=on-failure

[Install]
WantedBy=multi-user.target

• systemctl daemon-reload - reload systemd configuration
• systemctl enable next - enable service on system startup
• systemctl start next - start server
