How do I change the map or server name?

Use the installer: select Operation: Harsh Doorstop again, adjust the settings, and click Update. The installer rewrites the server name, map, player slots, and join password each time it runs.

Which ports does an Operation: Harsh Doorstop server need?

By default, port 27015 (UDP) is used for the game and port 27016 (UDP) for queries. The installer opens them in the Windows Firewall and, when you install through the dashboard, in your VPS's network firewall as well.

Introduction

You can host an Operation: Harsh Doorstop server on your own VPS with ZapX. You have full control over the system, and the Game Server Installer gets your server set up in just a few minutes—no remote desktop connection required. This guide explains what you need, how to install the server, and how to manage it afterward.

Operation: Harsh Doorstop: Set Up a Server on Your VPS

Requirements

Requirement	Operation: Harsh Doorstop
Operating system	Windows Server 2019 or later
Memory	At least 4 GB
Free disk space	At least 10 GB on drive C:

Info

The Game Server Installer only supports Operation: Harsh Doorstop on Windows. If your VPS runs Linux, install a Windows Server template under Settings > Reinstallation. This deletes all data on your VPS. Learn more in Server Reinstallation.

Install Operation: Harsh Doorstop

Open your VPS in the ZapX dashboard and go to the Tools tab. Select the Game Server Installer.
Under Your server's operating system, select the Windows tile.
Under Choose game, search for Operation: Harsh Doorstop and select it.
Under Set up server, configure the server name, starting map (for example, Argonne, Carentan, or Khafji), and player slots. You can find the game port and query port under Advanced settings.
Click Install on this VPS, then click Start installation.

The installer downloads Operation: Harsh Doorstop from Steam using SteamCMD (about 3 GB), sets it up, and starts it. For details about the installation process, see the Game Server Installer guide.

Info

Operation: Harsh Doorstop does not have a settings file for the installer to write to. The server name, map, player slots, and join password are passed when the server starts. The server also does not save a world; the map loads again after a few seconds.

You can also install Operation: Harsh Doorstop yourself using a command. In the last step, copy the displayed command, connect using Remote Desktop, then run it in Windows PowerShell as an administrator.

After installation

Once installation is complete, the installer displays your server address under How to connect. When you install through the dashboard, the installer does not set a join password. If you want one, install using a command; the script will prompt you for it privately. To connect, find your server in the in-game server list by its name, or connect directly using your VPS IP address and the port, which is 27015 by default. You can also find the IP address in the Overview of your VPS in the ZapX dashboard.

Your server files are located on the VPS at C:\ZapX-GameServers\operation-harsh-doorstop\:

Folder/file	Contents
`server\`	Operation: Harsh Doorstop server files
`server\HarshDoorstop\Saved\Config\WindowsServer\`	Settings and lists (`Admins.cfg`, `MapCycle.cfg`, `Bans.cfg`, `Whitelist.cfg`, `Game.ini`, `Engine.ini`)
`logs\server.log`	Server output

Start, stop, and restart the server

Your Harsh-Doorstop server starts automatically when your VPS boots and restarts if it crashes. To manage it, connect using Remote Desktop and use the shortcuts on the desktop:

Operation: Harsh Doorstop (operation-harsh-doorstop) - Start
Operation: Harsh Doorstop (operation-harsh-doorstop) - Stop
Operation: Harsh Doorstop (operation-harsh-doorstop) - Restart

Configuration

The installer writes the server name, map, player slots, and join password to the startup parameters every time it runs, including when you update the server. To change these values, use the installer: select Operation: Harsh Doorstop again, adjust the settings, and click Update.

The game reads the following lists from server\HarshDoorstop\Saved\Config\WindowsServer\ when it starts:

File	Contents
`Admins.cfg`	Server admins
`MapCycle.cfg`	Map rotation
`Bans.cfg`	Banned players
`Whitelist.cfg`	Players allowed to join

If a file does not exist yet, create it in this folder. After making changes, restart the server using Operation: Harsh Doorstop (operation-harsh-doorstop) - Restart.

Update the server

Updates are not installed automatically. To update, open the Game Server Installer again and select Operation: Harsh Doorstop. The installer detects the existing installation and displays Update. Alternatively, use the Operation: Harsh Doorstop (operation-harsh-doorstop) - Update shortcut on your VPS. Your lists in the settings folder will be kept.

Ports and firewall

Port	Protocol	Use
27015	UDP	Game
27016	UDP	Query

The installer opens these ports in the Windows Firewall. If you start the installation from the dashboard, it also opens them in your VPS's network firewall. If you installed using a command, check the ports there yourself.

Backups

Use the Operation: Harsh Doorstop (operation-harsh-doorstop) - Backup shortcut to back up the settings folder—including Admins.cfg, MapCycle.cfg, Bans.cfg, Whitelist.cfg, Game.ini, and Engine.ini—as a ZIP file at C:\ZapX-GameServers\_backups\operation-harsh-doorstop\. Use Operation: Harsh Doorstop (operation-harsh-doorstop) - Restore to restore a backup. Operation: Harsh Doorstop does not have a world, so backups only contain settings.

Your entire VPS is also backed up automatically every day. With an active ZapX Pass, you can restore these backups yourself and create your own backups. Learn more in Daily Backups, Restoring Backups, and Locked Actions.
