<h3>Scheduled Maintenance Scripts</h3>
<p>Create <code>restart.sh</code> (Linux) to keep the process alive:</p>
<pre><code>#!/bin/bash
cd /home/ricochet/ricochet-server
while true; do
./hlds_run -game ricochet -console -port 27015 \
+map rc_deathmatch +maxplayers 16 +sv_lan 0 +exec server.cfg
echo "Server crashed/restarted at $(date)" >> restart.log
sleep 5
done
</code></pre>
<p>Run it inside <code>tmux</code> or <code>screen</code>, or convert to a <code>systemd</code> service for automatic boot.</p>
<h2 id="maintenance">Maintenance & Best Practices</h2>
<ul>
<li><strong>Updates:</strong> rerun <code>steamcmd +login anonymous +app_update 90 validate +quit</code> after Valve pushes patches.</li>
<li><strong>Backups:</strong> copy the entire <code>ricochet/</code> directory (configs, logs, demos) before experimenting with mods.</li>
<li><strong>Performance:</strong> keep <code>sys_ticrate</code> around 300500; higher values increase CPU usage without visible benefit.</li>
<li><strong>Security:</strong> never reuse the same RCON password across servers; restrict RCON by IP using host firewalls when possible.</li>
<li><strong>Monitoring:</strong> enable <code>log on</code> and parse logs for <code>Banid</code>, <code>kick</code>, or crash traces.</li>
</ul>
<h2 id="troubleshooting">Troubleshooting</h2>
<div style="background:#78350f;padding:20px;border-left:4px solid #f59e0b;margin:20px 0;border-radius:4px;">
<ul style="color:#fde68a;line-height:1.8;">
<li><strong>Server does not appear in Steam listings:</strong> confirm <code>sv_lan 0</code>, firewall allows outbound UDP 27010-27012, and public IP is bound via <code>-ip</code>. Restart after making changes.</li>
<li><strong>Players get "Server is out of date":</strong> run a fresh SteamCMD update with <code>validate</code>. Old binaries are the primary cause.</li>
<li><strong>Packet loss or warping:</strong> reduce <code>sv_maxrate</code> and <code>sv_maxupdaterate</code>, and ensure the host is not power-saving the CPU. Monitor with <code>net_graph 3</code> in-game.</li>
<li><strong>Crash on launch in 64-bit Linux:</strong> missing 32-bit libraries. Install <code>lib32gcc-s1</code>, <code>lib32stdc++6</code>, and <code>lib32z1</code> (Debian/Ubuntu) or <code>glibc.i686</code> packages (RHEL).</li>
<li><strong>RCON brute-force noise:</strong> move RCON to a high random port using <code>-port</code> + <code>+rcon_password</code> and limit access with firewall source rules.</li>

<h3 style="color: #ffffff; margin-top: 0;">Required Ports</h3>
<p style="color: #e5e7eb;">The Ricochet 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="Ricochet Server" dir=in action=allow protocol=TCP localport=[PORT]
netsh advfirewall firewall add rule name="Ricochet 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>

<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>
