Installation & Setup

System Requirements

• OS: Linux (Ubuntu 20.04+ or Debian 11+ recommended) or Windows Server 2019+
• CPU: 2+ cores recommended (single-threaded performance important for most game servers)
• RAM: 512 MB–1 GB baseline minimum (more for larger player counts)
• Storage: 5GB+ for server files (SSD recommended for better performance)
• Network: Stable internet connection with low latency

Required Dependencies

• Open UDP 27960 (and increments for multiple instances)

Installation Steps

Linux (Ubuntu/Debian)

# Update system packages
sudo apt update && sudo apt upgrade -y

# Create server directory
mkdir -p ~/gameserver
cd ~/gameserver

# Download server files (method varies by game)
# Check official documentation for download links

Starting the Server

./etlded +set dedicated 2 +set net_port 27960 +set fs_game legacy +exec server.cfg

Windows Server

Download the server files from the official game website or through Steam (if applicable). Extract to a dedicated folder and run the server executable.

Manual Installation

This game requires manual download. Check the official game website or Steam store page for dedicated server downloads.

Server Configuration

After installation, you'll need to configure your server. Here's where to find the configuration files and what settings you can change.

Essential Settings

• Server Name: Set a descriptive name for your server
• Max Players: Configure based on your server's resources
• Password: Optional password protection for private servers
• Admin/RCON Password: Set a strong password for remote administration
• Game Mode: Configure game-specific modes and settings

Server Commands

Common administrative commands (access via console or RCON):

# Kick player
kick [player_name]

# Ban player
ban [player_name]

# Change map/level (syntax varies by game)
changelevel [map_name]

# Set admin password (if supported)
setadminpassword [password]

⚙️ Startup Parameters

Command Line Template

The server uses the following command line template:

+set dedicated 2 %GAME_TYPE% %IP% %PORT% %PLAYERS% %MAP%

Available Startup Parameters

The following parameters can be configured when starting the server:

Creating a Start Script

Linux (start.sh):

#!/bin/bash
cd /path/to/server
./server_executable [parameters] 2>&1 | tee server.log

chmod +x start.sh
./start.sh

Windows (start.bat):

@echo off
cd /d "%~dp0"
server_executable.exe [parameters]
pause

Running as a Service

Linux (systemd):

# Create service file: /etc/systemd/system/gameserver.service
[Unit]
Description=Wolfenstein: Enemy Territory Server
After=network.target

[Service]
Type=simple
User=gameserver
WorkingDirectory=/home/gameserver/server
ExecStart=/home/gameserver/server/start.sh
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target

# Enable and start service
sudo systemctl daemon-reload
sudo systemctl enable gameserver
sudo systemctl start gameserver
sudo systemctl status gameserver

🔧 Troubleshooting

Server Won't Start

Not visible on internet list

Forward UDP 27960; set dedicated 2; verify master server reachability; avoid NAT loopback issues.

Connection Issues

Can't Connect to Server

1. Verify server is running: ps aux | grep server
2. Check port is listening: netstat -an | grep [PORT]
3. Verify firewall rules (see Ports section above)
4. Check server IP: Use external IP, not localhost
5. Router/NAT: Ensure port forwarding is configured

High Latency/Lag

• Check server resource usage (CPU, RAM, disk I/O)
• Verify network bandwidth is adequate
• Consider server location relative to players
• Check for background processes consuming resources

Performance Issues

Server Lag

1. Monitor resources: Use htop or top
2. Check disk I/O: Use iotop
3. Review server logs for errors or warnings
4. Reduce player count or increase server resources
5. Optimize configuration based on server capacity

Memory Leaks

# Monitor memory usage
free -h
top -p $(pgrep -f server)

# Restart server regularly via cron if needed
0 4 * * * /home/gameserver/restart.sh

Performance Optimization

Server Tuning

• CPU: Ensure adequate CPU allocation; most game servers are single-threaded
• RAM: Allocate sufficient memory; monitor usage and adjust as needed
• Disk: Use SSD storage for better I/O performance
• Network: Ensure stable, low-latency connection

Operating System Optimization

# Increase file descriptor limits
echo "* soft nofile 65536" >> /etc/security/limits.conf
echo "* hard nofile 65536" >> /etc/security/limits.conf

# Network tuning
sysctl -w net.core.rmem_max=16777216
sysctl -w net.core.wmem_max=16777216
sysctl -w net.ipv4.tcp_rmem="4096 87380 16777216"
sysctl -w net.ipv4.tcp_wmem="4096 87380 16777216"

Monitoring

Set up monitoring to track server health:

• CPU and memory usage
• Network traffic and latency
• Player count and activity
• Error rates and crash logs

Backup Strategy

#!/bin/bash
# backup.sh - Run via cron
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/backups/gameserver"
SERVER_DIR="/home/gameserver/server"

# Create backup
tar -czf $BACKUP_DIR/backup_$DATE.tar.gz -C $SERVER_DIR .

# Keep only last 7 days
find $BACKUP_DIR -name "backup_*.tar.gz" -mtime +7 -delete

Security Best Practices

Firewall Configuration

# Minimal firewall - only allow necessary ports
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow [SERVER_PORT]/tcp
sudo ufw allow [SERVER_PORT]/udp
sudo ufw allow 22/tcp  # SSH
sudo ufw enable

Strong Passwords

• Use strong, unique passwords for admin/RCON access
• Never use default passwords
• Change passwords regularly
• Don't share admin credentials unnecessarily

Regular Updates

• Keep server software updated to the latest stable version
• Update operating system and dependencies regularly
• Subscribe to security advisories for your game
• Test updates on a staging server before production deployment

Access Control

• Limit SSH access to specific IPs if possible
• Use SSH keys instead of passwords
• Disable root login via SSH
• Implement fail2ban or similar intrusion prevention

DDoS Protection

• Consider DDoS protection services (Cloudflare, OVH, etc.)
• Implement rate limiting where supported
• Monitor for unusual traffic patterns
• Have an incident response plan
