|
||||
</code></pre>
|
||||
|
||||
<h2 id="performance">Performance Optimization</h2>
|
||||
|
||||
<h3>Server Tuning</h3>
|
||||
<ul>
|
||||
<li>MW3 requires <strong>specific port configuration</strong>:</li>
|
||||
<li>Game port: Your chosen port (e.g., 27016)</li>
|
||||
<li>Query port: Set to -1 (automatically becomes game port - 1)</li>
|
||||
<li>Auth port: Must be set to -18249</li>
|
||||
<li>Master server port: Set to -1 (disabled)</li>
|
||||
<li>Verify all three ports are open in firewall</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>Server Crashes on Startup</h3>

|
||||
echo "* soft nofile 65536" >> /etc/security/limits.conf
|
||||
echo "* hard nofile 65536" >> /etc/security/limits.conf
|
||||
|
||||
# Network tuning

|
||||
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>Check <code>games_mp.log</code> for error messages</li>

|
||||
<li>Error rates and crash logs</li>
|
||||
</ul>
|
||||
|
||||
<h3>Connection Problems</h3>
|
||||
<p><strong>Issue:</strong> Players cannot connect or timeout.</p>
|
||||
<p><strong>Solutions:</strong></p>
|
||||
<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>Verify firewall rules allow traffic on all required ports</li>
|
||||
<li>Check <code>sv_maxPing</code> setting</li>
|
||||
<li>Ensure server is not full (max 18 players)</li>
|
||||
<li>Disable password if testing: <code>set g_password ""</code></li>
|
||||
<li>Verify clients are using same MW3 version</li>
|
||||
<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>
|
||||
|
||||

|
||||
<p><strong>Solutions:</strong></p>
|
||||
<h3>Access Control</h3>
|
||||
<ul>
|
||||
<li>MW3 has a <strong>hard limit of 18 players</strong> - this is by design</li>
|
||||
<li>Do not attempt to exceed this limit as it will cause issues</li>
|
||||
<li>This is an engine limitation, not a configuration issue</li>
|
||||
<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>RCON Not Working</h3>
|
||||
<p><strong>Issue:</strong> Cannot connect via RCON.</p>
|
||||
<p><strong>Solutions:</strong></p>
|
||||
<h3>DDoS Protection</h3>
|
||||
<ul>
|
||||
<li>Verify <code>rcon_password</code> is set in <code>server.cfg</code></li>
|
||||
<li>Ensure TCP port is open (same as game UDP port)</li>
|
||||
<li>Use MW3-compatible RCON tools</li>
|
||||
<li>Test RCON from in-game console first</li>
|
||||
<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>
