GoRcon-ArmA

The Go based Rcon solution for ArmA servers with server management features

Features

Implemented:

• Stable and Secure Rcon Connection
• Allow Management of Rcon Servers
  • Automated Server Restarts
  • Sending timed Messages/Commands to Servers
  • Server WatchDog

Usage

The Tool consists of several parts. Main Part is the RCon library which connects to a given server and sends commands/handles responses. The other parts yet integrated are the Watcher and Scheduler.

The Watcher

The Watcher is responsible for starting and watching your game process. When using the Watcher you always have to let the Tool start your ArmA server otherwise the process won't be detected. When using the watcher as process manager, ending or killing gorcon-arma will also terminate your server process. This is a wanted feature as an automated restart of gorcon-arma would start a new server anyways which would then concur with the old one. On Windows the server is not being killed when gorcon-arma ends unexpected so take care of this when restarting it.

The Scheduler

The Scheduler is able to either send a string over RCon (like: say -1 hello all) or send a restart command. If the Watcher is enabled, the restart will be done by sending a SIGTERM/SIGKILL to the process. If there is only RCon the restart will send a '#restartserver' command. Please note that without any kind of watcher your server might not come back up. When declaring a command in your config as restart event, the command string will be ignored.

Note that the Scheduler has it's own schedule.json file containing the timetable (see below).

Getting Started

Binary

If you get the latest binary version from our storage server you also get this README, the example config.json and an example schedule.json (HINT: You can select all the files you need and download them as a zip file).

Debian Package (WIP)

If you want to use the pre-built debian package which also contains a systemd script for managing gorcon-arma (still being tested), you can get it by adding our bintray repository to your sources:

echo "deb https://dl.bintray.com/playnet/debian /" | sudo tee -a /etc/apt/sources.list

Then install via it's package name:

apt install gorcon-arma

Configuration

Once you got all required files installed you are ready to change the config.json according to your needs. When entering the ArmA path make sure to use the right formating, even on Windows the path has to use forward slashes(/)! Do not escape spaces on Windows as Golang is handling all that for you. Also note that logToFile and logToConsole are not supported on Windows, so we recommend keeping them disabled. All further configuration options are described below. For both keepAliveTimer and keepAliveTolerance we recommend leaving them to the standards unless issues arise.

Starting

As gorcon-arma is a single binary starting it is fairly easy. If you used the binary files simply start the gorcon-arma binary of your choice ./gorcon-arma_linux-amd64 If you used the Debian Package it is as simple as systemctl start gorcon-arma

Debugging

If you encounter any issues with GoRcon-ArmA and need help, we recommend to first start with more output logging: ./gorcon-arma_linux-amd64 --logtostderr=true -v=2

The Verbosity Level is categorized in the following order:

• 1 Usual Output (can be always on)
• 2 More Info
• 3 Debug Communication
• 4 Debug Internals
• 5 Intense Debug
• 10 Loop Debugging

Explanation for arma section

• enabled Whether or not RCon is enabled
• ip IP of the RCon Server
• port RCon Port as set in beserver.cfg
• password RCon Password as set in beserver.cfg
• keepAliveTimer The amount of seconds to wait until a keepAlivePacket is send to RCon (BattlEye Specification is min. 45sec)
• keepAliveTolerance The maximum tolerance between the sent keepAlives and the server response (higher means slower detection of disconnect, lower might cause unrequired reconnects)
• showChat Whether or not the Server Chat should be streamed to the console/stdout
• showEventsWhether or not the Server Events should be streamed to the console/stdout

Explanation for scheduler section

• enabled Wheteher or not the scheduler is enabled
• path Path to schedule.json (keep local if not required otherwise)

Explanation for watcher section

• enabled Wheteher or not the watcher is enabled
• path Path to the ArmA executable (linux or windows)
• params Array of parameters for ArmA (watch formating for linux)
• logToFile Enable or Disable stderr/stdout logging of game server (linux systems only)
• logFolder Set the folder path in which logfiles are being created
• logToConsole Enables streaming of the server output(logs) to the console (linux systems only)

Schedule Manual

The Scheduler implements a system like cronjobs. To learn more about it check out this link

{
    "schedule": [
        {
            "command": "say -1 Message every 5 minutes",
            "restart": false,
            "day": "*",
            "hour": "*",
            "minute": "*/5"
        }
    ]
}

• command Command to be executed (if not restart)
• restart If the Server should be restarted (overrides command)
• day Day of the Week to run the Event (0-6, 0 = Sunnday, * = Every Day)
• hour Hour of the Day to run the Event (0-23, * = Every Hour)
• minute Minute of the Hour to run the Event (0-60, * = Every Minute)

Scheduler Examples

Example Event to restart the Server every hour at xx:30am/pm

{
    "command": "",
    "restart": true,
    "day": "*",
    "hour": "*",
    "minute": "30"
}

Example Event to restart the Server every day at 12:08am

{
    "command": "",
    "restart": true,
    "day": "*",
    "hour": "12",
    "minute": "8"
}
