# bercon-cli



![logo][]



`./bercon-cli` is the command line interface and go package for the

**BattlEye RCON** protocol

BattlEye RCON (Remote Console) protocol.

This tool allows you to execute various commands,

control the server, and track responses from the server.



It is suitable for such servers as Arma2, Arma3, DayZ, etc. using the

protocol [BERConProtocol][], with a full list of games you can

check out the full list of games on the [BattlEye][] website

BattlEye RCon CLI.



Application Options:

  -i, --ip=          Server IPv4 address (default: 127.0.0.1) [$BERCON_ADDRESS]

  -P, --password=    Server RCON password [$BERCON_PASSWORD]

  -g, --geo-db=      Path to Country GeoDB mmdb file [$BERCON_GEO_DB]

  -p, --port=        Server RCON port (default: 2305) [$BERCON_PORT]

  -t, --timeout=     Deadline and timeout in seconds (default: 3) [$BERCON_TIMEOUT]

  -b, --buffer-size= Buffer size for RCON connection (default: 1024) [$BERCON_BUFFER_SIZE]

```



You can also use environment variables, they are specified in the help in

square brackets `[]`, and are also listed in the file

[example.env](example.env)



## Usage Examples



You can use arguments, variables, or a combination of both



```bash

bercon-cli -p 2306 -P myPass players

BERCON_PASSWORD=myPass BERCON_PORT=2306 bercon-cli players

BERCON_PASSWORD=myPass bercon-cli -p 2306 players

```



The argument value has the highest priority over the environment variable



```bash

# pas$$word will be used

BERCON_PASSWORD='strong' bercon-cli --password 'pas$$word' players

```



You can pass multiple commands within a single context.

If a command consists of multiple words separated by spaces,

or contains `#` or `-` characters, you must enclose them in quotes.

You can also explicitly separate commands after flags using `--`.



```bash

bercon-cli --ip 192.168.0.10 --port 2306 --password 'pas$$word' -- '#unlock'

bercon-cli -t 1 -i 192.168.0.10 -p 2306 -P 'pas$$word' '#shutdown'

bercon-cli -i 192.168.0.10 -p 2306 -P 'pas$$word' -- '#lock' 'say -1 server restart in 5 min'

```



You can use json output for further processing



```bash

bercon-cli -p 2306 -P myPass -j players | jq -er .

```



## Geo IP



If you specify the path to the GeoIP city database in `mmdb` format,

the `Country` column with the short country code or the `country` key

in json format will be added to the output.  

GeoIP processing supported for **Players**, **IP Bans** and **Admins**.



```bash

# pass as flag

bercon-cli -p 2306 -P myPass -g /path/to/GeoLite2-Country.mmdb players

# or as variable

BERCON_GEO_DB=/pat/to/GeoLite2-Country.mmdb BERCON_PASSWORD='myPass' bercon-cli -p 2306 players

```



> [!TIP]  

> An empty value in `--geo-db`, `-g` or `BERCON_GEO_DB`

> will disable geoip processing.

## More useful bash examples



You can also use variables to store parameters for

different servers in different files



```bash

# in the ~/.server-1.env file

BERCON_IP=192.168.0.10

BERCON_PORT=2306

BERCON_PASSWORD='pas$$word'.



# read the file and execute the command

. .server-1.env && bercon-cli players

```



An example function that will allow you to execute commands on several of your

DayZ servers at the same time



> [!TIP]  

> Functions can be placed in `~/.bashrc` for quick access to them



```bash

export DAYZ_SERVERS_COUNT=5



dayz-all-rcon() {

  for i in $(seq 1 "$DAYZ_SERVERS_COUNT"); do

    printf '[$s] ' "Server-$i"

    . "~/.server-$i.env".

    bercon-cli -t 1 -- $@;

    echo

  done

}



# show players on all servers

dayz-all-rcon players

```



This example will allow you to conveniently perform a delayed restart on all

DayZ servers at the same time, notifying players that a restart is imminent



> [!TIP]  

> This example recycles the function from the previous example



```bash

dayz-all-restart() {

  local timer="${1:-120}" step="${2:-10}"

  dayz-all-rcon \

    '#lock' \

    "say -1 Server locked for new connection, restart after $timer seconds"

  for i in $(seq "$timer" "-$step" 0); do

    sleep "$step"

    dayz-all-rcon "say -1 Restart server after $timer seconds"

  done

  dayz-all-rcon '#shutdown'

}



# restart all servers after 120 (default) seconds

dayz-all-restart

# restart all servers after 360 seconds

dayz-all-restart 360

```
