Dedicated Server manual

How to setup a dedicated server

Be aware that the following steps must be followed whenever Assetto Corsa is updated by Steam.

1) Go to your AC installation folder (Steam -> Assetto Corsa -> properties -> local files -> browse local files)
2) Open acServerManager.exe (latest version can be found in your Steam folder\steamapps\common\assettocorsa\server)
3) Click on Update Server Content
4) If your server is running on remote PC, upload the entire "server" folder. Remember to backup the three files listed in the section below: in this case just check for new settings in the new files and add them to your old ones.

If you want, you can also run acServerManager.exe with "/pack /nomsg" as arguments to have the same result of points 2 and 3 with no window.

If you are kicked from the server because of a mismatch (car or track) you need to update your game OR probably the server is not updated with the latest content.

How to create and start an online session

!!! ALERT !!!
Please be aware that, in order to have a good online experience, AC requires that you have a good quality connection (both ping and stability). So, please, do not play online while your connection is under stress (torrent, Windows updates, shared connections) and,
most importantly, do not run servers using extreme configurations. This means that if your connection has a low upload bandwidth, you should not run a server with 24 slots.

Please have a look at the acServerManager tool to have an idea about your approximate bandwidth usage.


The server will read the following two configuration files:
"/cfg/server_cfg.ini"
"/cfg/entry_list.ini"

Add the blacklist file which stores the client's Steam GUID who will not be allowed on the server:
"/blacklist.txt"

These files can be generated and managed by the "acServerManager.exe" application located in your Assetto Corsa/server folder, or can be manually managed by you using a text editor such as Windows' notepad.

To start the server you need to run the acServer.exe (watch out for the server message in case of errors)
We suggest you run the acServer.bat batch that will dump the log of the server directly into the exe's folder under an unique name (timestamp). Be aware that when starting the batch file, an empty black CMD window will appear on the screen: it is normal as the server will write the messages in the file. These files are useful for storing online session's data (client's GUID, etc) and enable the staff to support you in case of any issues.

BASE_TEMPERATURE_ROAD=6    ; Relative road temperature: this value will be added to the final ambient temp. In this example the road temperature will be between 22 (16 + 6) and 26 (20 + 6). It can be negative.
VARIATION_ROAD=1           ; variation of the road's temperature. Like the ambient one.

------ UPDATE ------
; Be aware the session wind is static for all its duration; speed and direction is random related to the values below

WIND_BASE_SPEED_MIN=3     ; Min speed of the session possible
WIND_BASE_SPEED_MAX=15     ; Max speed of session possible (max 40)
WIND_BASE_DIRECTION=30      ; base direction of the wind (wind is pointing at); 0 = North, 90 = East etc
WIND_VARIATION_DIRECTION=15   ; variation (+ or -) of the base direction

; so in this example the then wind speed can be between 3 and 15 and direction between 15 and 45
------------------------

An entire section ([BOOK],[PRACTICE], etc ) can be removed: for example, if you want a race without a practice session.

You can add other WEATHER sections (WEATHER_1, WEATHER_2 etc), and each new session will be randomly selected from these.
For road temperatures relative to ambient temperature, weather and time of the day, please check the acServerManager tool.

Mandatory Pit : a pit window can be added to the race session. As a design choice, players need to cross the pitentry line and stop at their pit box within the pit window to have a valid pit stop. Players may make additional pit stops before and after the pit window, but only making a mandatory stop in the indicated pit window will validate their race. Server admins must decide on a pit window that allows all players to comfortably make a pit stop under normal racing conditions.

Reversed grid races: the race session will be restarted in reversed grid order based on the standings of the previous race. Players disqualified in the first race will start from the back of the grid in the second race, regardless of their position being within the reversed grid range.

This will be improved in the next update.

entry_list.ini
Code:
[CAR_0]                    ; car index -> from 0 to XXX
DRIVERNAME=                ; Driver name that will appear on the lobby
TEAM=                      ; Team of driver
MODEL=                     ; car model - that's exactly the car folder's name (into the "content/cars" folder)
SKIN=                      ; car skin -  that's exactly the skin folder's name (into the "content/cars/MODEL/skins" folder)
GUID=                      ; STEAM64 GUID
SPECTATOR_MODE=            ; leave it to 0
BALLAST=0                  ; how many kg of ballast to be added to this car. Excessive ballast can severely affect handling and car behaviour!

------ UPDATE ------
RESTRICTOR=0      ; from 0 to 100, cuts the car's engine power. 100=100% restrictor plate. It limits power in the top range of the power band, will not kill total power. Effective handicap depends on car and track, experimentation needed. Advantage over BALLAST is that it does not affect handling. 0=no restrictor plate, maintains original power.
------------------------

FIXED_SETUP=               ; if the line is there but empty, the server will search a defined "MODELNAME.ini" (for example "bmw_m3_e30.ini") into the "setups" folder. Otherwise you can insert a setup name in as value ("setupname.ini")
Your STEAM64 GUID can be found in your "documents/assetto corsa/logs/log.txt" just after you have run a driving session in AC.
Code:
Steam Community ID:76561197983XXXXXX
The setups can be only partially fixed: the user can remove sections or keys from the ini file to make those part "customizable". Everything that is part of the file will be locked in the clients.
So if you want a fixed setup with free fuel quantity then the "[FUEL]VALUE=XXX " must be removed.


Example for a server in pickup mode
You need to insert at least a number of cars sections equal to the MAX_CLIENTS value or higher than that. So if the server is allowing 10, cars then the entry list must have cars from [CAR_0] to [CAR_9] at least.
Code:
[CAR_0]
DRIVERNAME=
TEAM=
MODEL=ferrari_458_gt2       ; this MUST BE one of the car allowed in the "server_cfg.ini"
SKIN=black_matte            ; car skin -  that's exactly the skin folder's name (into the "content/cars/ferrari_458_gt2/skins" folder)
GUID=
SPECTATOR_MODE=0
BALLAST=0
FIXED_SETUP=
Server administration mainly works through the server chat. It is MANDATORY to set the "ADMIN_PASSWORD" in the server_cfg.ini file.
Code:
/help: prints the list of the available commands
/admin: become administrator for the server. ex, if the password is "kunos" the command is "/admin kunos"
/next_session: moves to next session
/ksns: moves to next session
/restart_session: restart the session
/ksrs: restart the session
/kick: kick a user using the rules (blacklist etc) of the server. To kick a player named "The Player": /kick The Player
/client_list: shows the full car list by CAR_ID : "PlayerName"
/kick_id: kick the user who occuping CAR_ID. To kick a player named "The Player" who's occuping CAR_15: /kick_id 15
/ballast: add weight to the CAR_ID. To add 200 kg to the CAR_15: /ballast 15 200
/restrictor: cut engine power to the CAR_ID. To add 50% restrictor to the CAR_15:  /restrictor 15 50
/ban_id: ban the user who occuping CAR_ID. To ban a player named "The Player" who's occuping CAR_15: /ban_id 15

Shared GUID: each car in the entry list can feature multiple GUIDs, sperated by a ';' . Players can share that car (one at once). The name inserted in the entry list is used as driver name.

GUID=76561197983XXXXXX;76561197983YYYYYY;76561197983ZZZZZZ;76561197983WWWWWW

This can also be used as partial driver swap and it's the 1st step to a more complete functionality: in fact setup will not be shared (can be solved using server fixed setup system), the new player will have a brand new car and mandatory pit will not work (yet).

Multiple servers on the same PC

To run more than a server at the same time on the same PC, remember that you have to use different ports for each one, and it is advised to run different executables (acServer for the first server, acServer2 for the second one and so on, or create another server folder somewhere)
If you want to use this feature on the acseservermanager, it is mandatory to fill the Server Path field with the new .exe path.
