Server Commands

Console commands can be executed either using an RCon tool, directly from the server console interface, a server configuration file, the server command line, or (if a resource is allowed by the ACL) the ExecuteCommand function.

Adding a custom RCon command can be done using the RegisterCommand function on the server, or the (legacy) rconCommand event.

Resource commands

start [resourceName]

Starts the resource specified in the argument, if it was stopped. It is also possible to specify a category name, such as start [cars].


start lambda-menu
start [cars]

stop [resourceName]

Stops the resource specified in the argument, if it was started. As with start, one can also specify a category name.


stop mymode

ensure [resourceName]

Restarts the resource specified in the argument, if it was started. If it wasn't, starts the resource specified in the argument.

As with start and stop, one can also specify a category name.


ensure my-testing-resource

restart [resourceName]

Restarts the resource specified in the argument, if it was started. Also supports category names.


restart lambda-menu


Rescans the resources folder and loads all resource manifests in them, also making new resources available to start using start.



Global commands

exec [filename]

Runs the commands specified in the filename. Commonly seen as FXServer.exe +exec server.cfg.


exec server_nested.cfg

Management commands


Shows a list of players with their primary identifier, server ID, name, endpoint, and ping.



clientkick [id] [reason]

Kicks the client with the specified server ID (as seen in status) from the server, for the stated reason.


clientkick 43 You're a superstitious idiot!

say [message]

Sends a message in the chat as console.


say Hi, everybody!


Opens or closes the server debug GUI.

Configuration variables

onesync [on/off/legacy]

Defines which mode of state awareness to use.

  • Off: No state awareness at all, clients will use the standard GTA/RAGE P2P networking model, and the server will only function as a relay.
  • On: Full state awareness and server-determined entity routing.
  • Legacy: Compatibility mode for scripts that expect all players to exist on each client. Not recommended due to performance issues and graphical glitches.

sv_maxClients [newValue]

A console variable that specifies the maximum amount of clients that the server can normally have, as an integer from 1 to 1024.

Values starting at 32 will require onesync to be set to on or legacy, and values above 64 will require onesync to be set to on.

sv_endpointPrivacy [newValue]

A boolean variable that, if true, hides player IP addresses from public reports output by the server.

sv_hostname [newValue]

A string variable that contains the server host name.

sv_authMaxVariance [newValue]

Variance is how likely the user's id will change for a given provider (i.e. 'steam', 'ip', or 'license').

A console variable as an integer from 1-5 (default 1); from least to most likely to change.

sv_authMinTrust [newValue]

Trust is how unlikely it is for the user's identity to be spoofed by a malicious client.

A console variable as an integer from 1-5 (default 5); from least to most trustworthy (5 being a method such as external three-way authentication).

load_server_icon [fileName.png]

A console command which loads a specfied icon and sets it as the server icon. The icon needs to be a 96x96 PNG file.


load_server_icon "my-server.png"

rcon_password [password]

Sets the RCon password. This being unset means RCon is disabled.

steam_webApiKey [key]

Sets a Steam Web API key, which is required to allow for Steam identifiers to be returned by the server.

Access control commands

add_ace [principal] [object] [allow|deny]

Adds an access control entry to the server's access control list.


add_ace group.admin command.potato allow
add_ace identifier.steam:110000112345678 deny

add_principal [child_principal] [parent_principal]

Sets a principal to inherit from another principal.


# makes identifier.steam:110000112345678 inherit from group.admin
add_principal identifier.steam:110000112345678 group.admin

remove_ace [principal] [object] [allow|deny]

Removes a specified ACE from the server's access control list.


remove_ace identifier.steam:110000112345678 deny

remove_principal [child_principal] [parent_principal]

Removes a specified principal inheritance entry.


remove_principal identifier.steam:110000112345678 group.admin

test_ace [principal] [object]

Tests if a principal is allowed or denied access to a given object.

Example: test_ace group.admin command.adminstuff
