<h3>Firewall Configuration Examples</h3>
<h4>UFW (Ubuntu/Debian)</h4>
<pre><code>sudo ufw allow 7777/tcp comment 'Terraria server'
<h2 id="ports">🔌 Network Ports</h2>

<h3 style="color: #ffffff; margin-top: 0;">Required Ports</h3>
<p style="color: #e5e7eb;">The Terraria 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
</code></pre>
<h4>FirewallD (CentOS/RHEL/Fedora)</h4>
<pre><code>sudo firewall-cmd --permanent --add-port=7777/tcp
# 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="Terraria Server" dir=in action=allow protocol=TCP localport=[PORT]
netsh advfirewall firewall add rule name="Terraria Server" dir=in action=allow protocol=UDP localport=[PORT]
</code></pre>
<h4>Windows Firewall</h4>
<pre><code># Run in PowerShell as Administrator
New-NetFirewallRule -DisplayName "Terraria Server" -Direction Inbound -Protocol TCP -LocalPort 7777 -Action Allow
</code></pre>
<h4>iptables (Legacy Linux)</h4>
<pre><code>sudo iptables -A INPUT -p tcp --dport 7777 -j ACCEPT
sudo service iptables save
</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>

<h2 id="troubleshooting">🔧 Troubleshooting</h2>
<h3>Server Won't Start</h3>
<p><strong>Problem:</strong> Server fails to launch or crashes immediately.</p>
<p><strong>Solutions:</strong></p>
<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 logs for error messages</li>
<li>Verify all paths in serverconfig.txt are correct</li>
<li>Ensure port 7777 isn't already in use (<code>netstat -an | grep 7777</code>)</li>
<li>Check file permissions (Linux: <code>chmod +x TerrariaServer*</code>)</li>
<li>Verify world file isn't corrupted</li>
<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>Players Cannot Connect</h3>
<p><strong>Problem:</strong> Players can't join the server.</p>
<p><strong>Solutions:</strong></p>
<ul>
<li>Verify port 7777 TCP is forwarded on router</li>
<li>Check firewall allows traffic on port 7777</li>
<li>Confirm password is correct (case-sensitive)</li>
<li>Use external IP address, not local/LAN IP</li>
<li>Test with <code>telnet SERVERIP 7777</code></li>
<li>Ensure server is running and accepting connections</li>
</ul>
<h3>Performance Issues</h3>
<h3>Lag and Performance Issues</h3>
<p><strong>Problem:</strong> Server experiences lag or stuttering.</p>
<p><strong>Solutions:</strong></p>
<ul>
<li>Reduce max players if exceeding capacity</li>
<li>Use SSD instead of HDD for better I/O</li>
<li>Increase server RAM allocation</li>
<li>Disable or reduce mods/plugins</li>
<li>Clean up excessive items/projectiles in world</li>
<li>Use smaller world size for lower player counts</li>
</ul>
<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>
<h3>World Corruption</h3>
<p><strong>Problem:</strong> World file corrupted or won't load.</p>
<p><strong>Solutions:</strong></p>
<ul>
<li>Restore from backup (always maintain backups!)</li>
<li>Try loading world in single-player Terraria client</li>
<li>Use world repair tools if available</li>
<li>Check disk for errors</li>
<li>Avoid forced server shutdowns</li>
</ul>
<h4>Memory Leaks</h4>
<pre><code># Monitor memory usage
free -h
top -p $(pgrep -f server)
<h3>Mod/Plugin Issues</h3>
<p><strong>Problem:</strong> Mods not loading or causing crashes.</p>
<p><strong>Solutions:</strong></p>
<ul>
<li>Ensure mod/plugin versions match Terraria version</li>
<li>Check for mod conflicts</li>
<li>Update TShock and plugins to latest versions</li>
<li>Review mod documentation for dependencies</li>
<li>Test mods individually to identify problematic ones</li>
</ul>
# Restart server regularly via cron if needed

<h2 id="performance">Performance Optimization</h2>
<h3>Server Sizing Guidelines</h3>
<h3>Server Tuning</h3>
<ul>
<li><strong>Small (2-4 players):</strong> 1GB RAM, dual-core CPU</li>
<li><strong>Medium (5-8 players):</strong> 2-4GB RAM, dual/quad-core CPU</li>
<li><strong>Large (10-16 players):</strong> 4-8GB RAM, quad-core CPU</li>
<li><strong>Modded servers:</strong> Add 2-4GB RAM depending on mod count</li>
<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>

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># Linux backup script
#!/bin/bash
WORLD_DIR="/path/to/Terraria/Worlds"
BACKUP_DIR="/path/to/backups"
<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 $BACKUP_DIR/terraria_backup_$DATE.tar.gz $WORLD_DIR
tar -czf $BACKUP_DIR/backup_$DATE.tar.gz -C $SERVER_DIR .
# Keep only last 14 days
find $BACKUP_DIR -name "terraria_backup_*.tar.gz" -mtime +14 -delete
# Keep only last 7 days
find $BACKUP_DIR -name "backup_*.tar.gz" -mtime +7 -delete
</code></pre>
<h3>Automated Restarts</h3>
<p>Set up daily restarts for optimal performance:</p>
<pre><code># Linux crontab for 4 AM restart
0 4 * * * /path/to/restart_terraria.sh
<h2 id="security">Security Best Practices</h2>
# restart_terraria.sh:
#!/bin/bash
pkill -9 TerrariaServer
sleep 5
cd /path/to/terraria
screen -dmS terraria ./TerrariaServer.bin.x86_64 -config serverconfig.txt
<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>
