<div style="background: #1e3a5f; padding: 20px; border-left: 4px solid #3b82f6; margin: 20px 0; border-radius: 4px;">
<h3 style="color: #ffffff; margin-top: 0;">Required Ports</h3>
<p style="color: #e5e7eb;">The Arma 2: Combined Operations server typically uses a configurable port. Check your server configuration files for the specific port settings.</p>
<h3 style="color: #ffffff; margin-top: 20px;">Firewall Configuration</h3>
<p style="color: #e5e7eb;">Allow server ports through your firewall:</p>
<pre><code style="color: #a5b4fc;"># UFW (Ubuntu/Debian)
sudo ufw allow [PORT]/tcp
sudo ufw allow [PORT]/udp
sudo ufw reload
# FirewallD (CentOS/RHEL)
sudo firewall-cmd --permanent --add-port=[PORT]/tcp
sudo firewall-cmd --permanent --add-port=[PORT]/udp
sudo firewall-cmd --reload
# Windows Firewall
netsh advfirewall firewall add rule name="Arma 2: Combined Operations Server" dir=in action=allow protocol=TCP localport=[PORT]
netsh advfirewall firewall add rule name="Arma 2: Combined Operations Server" dir=in action=allow protocol=UDP localport=[PORT]
</code></pre>
<h3 style="color: #ffffff; margin-top: 20px;">⚠️ Port Security Notes</h3>
<ul style="color: #fef3c7; line-height: 1.8;">
<li>Only open ports that are necessary for the game server to function</li>
<li>Consider using non-standard ports to reduce automated attacks</li>
<li>If using cloud hosting, configure security groups properly</li>
<li>Monitor connection attempts and unusual traffic patterns</li>
</ul>
</div>

<h3>Creating a Start Script</h3>
<p><strong>Linux (start.sh):</strong></p>
<pre><code>#!/bin/bash
cd /path/to/server
./server_executable [parameters] 2>&1 | tee server.log
</code></pre>
<pre><code>chmod +x start.sh
./start.sh
</code></pre>
<p><strong>Windows (start.bat):</strong></p>
<pre><code>@echo off
cd /d "%~dp0"
server_executable.exe [parameters]
pause
</code></pre>
<h3>Running as a Service</h3>
<p><strong>Linux (systemd):</strong></p>
<pre><code># Create service file: /etc/systemd/system/gameserver.service
[Unit]
Description=Arma 2: Combined Operations 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
</code></pre>
<pre><code># Enable and start service
sudo systemctl daemon-reload
sudo systemctl enable gameserver
sudo systemctl start gameserver
sudo systemctl status gameserver
</code></pre>
<h2 id="troubleshooting">🔧 Troubleshooting</h2>
<h3>Server Won't Start</h3>
<h4>Check Server Logs</h4>
<pre><code># View recent log entries
tail -f server.log
# Or check system logs
journalctl -u gameserver -f
</code></pre>
<h4>Port Already in Use</h4>
<pre><code># Find what's using the port
sudo lsof -i :[PORT]
sudo netstat -tulpn | grep [PORT]
# Kill the process or change server port
</code></pre>
<h4>Missing Dependencies</h4>
<p>Ensure all required dependencies are installed. Check the error messages for missing libraries or packages.</p>
<h3>Connection Issues</h3>
<h4>Can't Connect to Server</h4>
<ol>
<li><strong>Verify server is running:</strong> <code>ps aux | grep server</code></li>
<li><strong>Check port is listening:</strong> <code>netstat -an | grep [PORT]</code></li>
<li><strong>Verify firewall rules</strong> (see Ports section above)</li>
<li><strong>Check server IP:</strong> Use external IP, not localhost</li>
<li><strong>Router/NAT:</strong> Ensure port forwarding is configured</li>
</ol>
<h4>High Latency/Lag</h4>
<ul>
<li>Check server resource usage (CPU, RAM, disk I/O)</li>
<li>Verify network bandwidth is adequate</li>
<li>Consider server location relative to players</li>
<li>Check for background processes consuming resources</li>
</ul>
<h3>Performance Issues</h3>
<h4>Server Lag</h4>
<ol>
<li><strong>Monitor resources:</strong> Use <code>htop</code> or <code>top</code></li>
<li><strong>Check disk I/O:</strong> Use <code>iotop</code></li>
<li><strong>Review server logs</strong> for errors or warnings</li>
<li><strong>Reduce player count</strong> or increase server resources</li>
<li><strong>Optimize configuration</strong> based on server capacity</li>
</ol>
<h4>Memory Leaks</h4>
<pre><code># Monitor memory usage
free -h
top -p $(pgrep -f server)
# Restart server regularly via cron if needed
0 4 * * * /home/gameserver/restart.sh
</code></pre>
<h2 id="performance">Performance Optimization</h2>
<h3>Server Tuning</h3>
<ul>
<li><strong>CPU:</strong> Ensure adequate CPU allocation; most game servers are single-threaded</li>
<li><strong>RAM:</strong> Allocate sufficient memory; monitor usage and adjust as needed</li>
<li><strong>Disk:</strong> Use SSD storage for better I/O performance</li>
<li><strong>Network:</strong> Ensure stable, low-latency connection</li>
</ul>
<h3>Operating System Optimization</h3>
<pre><code># Increase file descriptor limits
echo "* soft nofile 65536" >> /etc/security/limits.conf
echo "* hard nofile 65536" >> /etc/security/limits.conf
# Network tuning
sysctl -w net.core.rmem_max=16777216
sysctl -w net.core.wmem_max=16777216
sysctl -w net.ipv4.tcp_rmem="4096 87380 16777216"
sysctl -w net.ipv4.tcp_wmem="4096 87380 16777216"
</code></pre>
<h3>Monitoring</h3>
<p>Set up monitoring to track server health:</p>
<ul>
<li>CPU and memory usage</li>
<li>Network traffic and latency</li>
<li>Player count and activity</li>
<li>Error rates and crash logs</li>
</ul>
<h3>Backup Strategy</h3>
<pre><code>#!/bin/bash
# backup.sh - Run via cron
DATE=$(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
</code></pre>
<h2 id="security">Security Best Practices</h2>
<h3>Firewall Configuration</h3>
<pre><code># 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
</code></pre>
<h3>Strong Passwords</h3>
<ul>
<li>Use strong, unique passwords for admin/RCON access</li>
<li>Never use default passwords</li>
<li>Change passwords regularly</li>
<li>Don't share admin credentials unnecessarily</li>
</ul>
<h3>Regular Updates</h3>
<ul>
<li>Keep server software updated to the latest stable version</li>
<li>Update operating system and dependencies regularly</li>
<li>Subscribe to security advisories for your game</li>
<li>Test updates on a staging server before production deployment</li>
</ul>
<h3>Access Control</h3>
<ul>
<li>Limit SSH access to specific IPs if possible</li>
<li>Use SSH keys instead of passwords</li>
<li>Disable root login via SSH</li>
<li>Implement fail2ban or similar intrusion prevention</li>
</ul>
<h3>DDoS Protection</h3>
<ul>
<li>Consider DDoS protection services (Cloudflare, OVH, etc.)</li>
<li>Implement rate limiting where supported</li>
<li>Monitor for unusual traffic patterns</li>
<li>Have an incident response plan</li>
</ul>
