# Killing Floor 2

![](https://1934041264-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LJf1_IiU2L1vVxT7iNe%2Fuploads%2FvRZZ1E4WHaVnowPqxmAU%2Fkf2banner.jpg?alt=media\&token=40d7a8d9-2fd8-4811-8912-b2611e2944c1)

## Server Settings

LinuxGSM installations contain `configSubDir=servername` in the command line by default, which creates a folder for config files named after the server. The default directory is `/home/user/serverfiles/KFGame/Config/kf2server` . Use these files to change server settings.

## Ports

| Description | Port    | Protocol |
| ----------- | ------- | -------- |
| Game        | `7777`  | UDP      |
| Query       | `27015` | UDP      |
| Web Admin   | `8080`  | TCP      |
| Steam       | `20560` | UDP      |

* **Game Port** Handled by: `LinuxServer-KFEngine.ini`
* **Query Port** Handled automatically or handled by parameters. The formula for finding query port assigned automatically is 19238 + assigned game port.
* **Web Admin** Handled by: `KFWeb.ini`
* **Steam Port** Handled automatically. The formula for finding the steam port is 12783 + Game Port.

## Workshop

{% hint style="danger" %}
Players on the Epic Store will not be able to download files hosted with the Steam Workshop.
{% endhint %}

Workshop content is added in `LinuxServer-KFEngine.ini` in the `OnlineSubsystemSteamworks.KFWorkshopSteamworks` section

{% hint style="danger" %}
Ensure the game server is stopped before editing the file to prevent it being overwritten.
{% endhint %}

```
KFGame/Config/kf2server/LinuxGSM-KFEngine.ini
```

```
[OnlineSubsystemSteamworks.KFWorkshopSteamworks]
ServerSubscribedWorkshopItems=605633924
ServerSubscribedWorkshopItems=605551918
ServerSubscribedWorkshopItems=605549089
ServerSubscribedWorkshopItems=605532351
```

This will only work for Workshop items that the server downloads itself, that are listed in the \[OnlineSubsystemSteamworks.KFWorkshopSteamworks] section as described above.

1. Make sure that the server is not running. If it is running, the Workshop setup will be overridden the next time you restart the server.
2. Find the section \[IpDrv.TcpNetDriver] in the PCServerEngine.ini config file.
3. Add the line "DownloadManagers=OnlineSubsystemSteamworks.SteamWorkshopDownload" to that section. If there are other "DownloadManagers=" lines, make sure this one is the first.
4. Do not delete anything from this section, except (optionally) other DownloadManagers= lines.

### Workshop maps as the starting map

{% hint style="warning" %}
Do not set a Workshop map as the starting map until the server has downloaded it. If the map is not downloaded yet, the server aborts at `LoadMap` and fails to start.
{% endhint %}

Start the server on a stock map first, such as the default `KF-BioticsLab`, so it can download the Workshop items listed in `ServerSubscribedWorkshopItems`. Once the download has finished, the Workshop map can be used as the starting map by setting `defaultmap` in the LinuxGSM config.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.linuxgsm.com/game-servers/killing-floor-2.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
