This shell script has number of uses related to SRB2/SRB2Kart/Ring Racers server.

Mainly, the script obtains information about IP, number of players, gametype, etc. from https://ms.srb2.org and https://ms.kartkrew.org, which allows user to connect directly to selected server from SRB2/SRB2Kart/Ring Racers Master Server list.

Features

• Connecting directly to selected server's IP from SRB2/SRB2Kart/Ring Racers Master Server,
• Starting server and playing, or just creating dedicated one,
• Checking if server is reachable (using jameds.org's Port Checker),
• Runs on Linux, macOS and Windows (Git Bash).

Dependencies

• Basic system utilities like GNU Coreutils, BusyBox or macOS out-of-the-box system utilities,
• Bash or any POSIX compliant shell,
• Findutils,
• Which,
• Curl,
• Gawk,
• Ncurses.

Additionally, Windows users need to have installed Git Bash to run this script.

Dependencies Installation

1. In terminal enter this following command:

• Debian/Ubuntu/Debian based/Ubuntu based: sudo apt install make git debianutils coreutils findutils ncurses-bin curl gawk,

• Arch/Arch based: sudo pacman -S --needed make git which coreutils findutils ncurses curl gawk,

• Gentoo/Gentoo based: sudo emerge -av dev-vcs/git sys-apps/which sys-apps/coreutils sys-apps/findutils sys-libs/ncurses net-misc/curl sys-apps/gawk,

• Fedora/Fedora based: sudo dnf install make git which coreutils findutils ncurses curl gawk,

• Fedora Silverblue/Fedora Kinoite/Universal Blue (Bazzite, Aurora): rpm-ostree install -A --allow-inactive make git which coreutils findutils ncurses curl gawk,

• Immutable systems like Steam Deck's SteamOS need rootless method of getting dependencies to avoid issues with wiping out installed packages after system's update or not to be able to write to certain path, like "/usr/local":

  • Install dependencies with package manager Homebrew: brew install make git coreutils findutils ncurses curl gawk.

Windows:

1. Installing Git Bash:

• Watch this video from 7:19 to 9:33 in HERE,

2. Git Bash can be found on start menu,

3. The rest of dependencies are installed, if you followed video.

macOS:

1. In terminal enter this following command:

• Homebrew: brew install gawk curl,

     - This script does not set port forwarding and open port in system's firewall for you. You need to do this manually on your router and system. For more information read the guide in: https://www.jameds.org/portforward.

     - To automate inputting in script for hosting server, do for example 'echo "1\n3" | srb2srv -d [path to directory of addons for dedicated server]', which means it will make input to list dedicated server in Custom room on Master Server.

     - Full path to game's main configuration file can be set with SRB2MAINCFG, SRB2KARTMAINCFG or RINGRACERSMAINCFG variable to shell configuration file, otherwise script assumes default file, if SRB2MAINCFG, SRB2KARTMAINCFG or RINGRACERSMAINCFG is not set.

     - There is also additional SRB2CFG, SRB2KARTCFG and RINGRACERSCFG variables of other configuration files, which can temporary override settings of set SRB2MAINCFG, SRB2KARTMAINCFG and RINGRACERSCFG.

     - To turn off automatic restart of server after error, set environment variable "export NOSRB2SRVLOOP=1".

     - Other environment variables to use. To activate them with value "1", do for example "export SRB2SRVDEBUG=1":
