Zandronum Server Setup Guide

Available in: ESPAÑOL PORTUGUÊS (BRASIL)

This guide covers how to set up your Zandronum dedicated server on Legion Hosting, configure startup variables, manage WAD files, set game modes, and connect to your server. Zandronum is a multiplayer-focused Doom source port based on Skulltag, supporting Doom, Doom II, Heretic, Hexen, and custom WADs. For admin commands and server management, see Zandronum Admin Commands.

Note: This server ships with Freedoom as the default IWAD, so no commercial Doom WAD is required to get started. You can upload your own IWADs and PWADs for different gameplay.

1. First Start

  1. Log in to GPanel and select your Zandronum server.
  2. Go to the Startup tab and review the configurable variables (see Section 2).
  3. Set your desired MAP and IWAD. The default IWAD is freedoom1.wad.
  4. Return to the Console tab and click Start.
  5. Wait for UDP Initialized. in the console, confirming successful startup.
Ports are randomly assigned unless you have a private IP. Check the Network tab in GPanel for your assigned port. See How to Find Your Server IP and Port.

2. GPanel Startup Variables

VariableDefaultDescription
MAX_PLAYERS16Maximum players allowed on the server.

3. WAD File Management

Zandronum uses two WAD directories:

DirectoryPurpose
IWAD/Main game WADs (doom.wad, doom2.wad, freedoom1.wad, etc.)
PWAD/Mod/addon WADs loaded with -file

Upload WAD files via SFTP to the appropriate directory. See How to Upload Files via SFTP.

Using commercial Doom WADs: If you own Doom or Doom II on Steam, you can find the WAD files in the game's Steam directory and upload them to the IWAD/ folder.

4. Server Configuration (zandronum.ini)

The server uses zandronum.ini for additional configuration. This file is auto-generated on first start.

Game-Specific Auto-Exec

Create game-specific config files for automatic execution:

doom.cfg      -- Loaded for Doom games
heretic.cfg   -- Loaded for Heretic
hexen.cfg     -- Loaded for Hexen
strife.cfg    -- Loaded for Strife

5. Access Control Files

Zandronum creates three plain-text files for access control:

  • adminlist.txt -- Admin IP addresses.
  • whitelist.txt -- Whitelisted players.
  • banlist.txt -- Banned players.

6. How to Connect

Option A -- Zandronum/Doomseeker Browser

  1. Download Doomseeker (included with Zandronum) or use the built-in server browser.
  2. Search for your server by name or IP.
  3. Ensure you have the same IWAD and PWADs as the server.
  4. Select and connect.

Option B -- Console Connect

  1. Open Zandronum and press the console key (~).
  2. Type: 
    connect <your-server-ip>:<port>
