Network Configuration and Optimization
Welcome to our comprehensive system administration documentation portal. This section covers advanced network configuration, security hardening, and performance optimization techniques for modern Linux systems.
Recent Documentation Updates

- NGINX Configuration for Reverse Proxy Setup
- SSL/TLS Security Best Practices
- Firewall Configuration and Network Security
System Requirements
For optimal performance, we recommend the following system specifications:
- Operating System: Ubuntu 20.04 LTS or CentOS 8+
- CPU: 2+ cores recommended for production
- RAM: 4GB minimum, 8GB recommended
- Storage: 50GB available space
- Network: Stable internet connection
Quick Start Commands
# Check system status
systemctl status nginx
# View network configuration
ip addr show
# Check active connections
ss -tuln
Performance Tuning
For high-traffic environments, consider the following kernel optimizations:
# TCP buffer sizes
sysctl -w net.core.rmem_max=33554432
sysctl -w net.core.wmem_max=33554432
# Enable BBR congestion control
sysctl -w net.ipv4.tcp_congestion_control=bbr
sysctl -w net.core.default_qdisc=fq
Note: These changes require root privileges and should be tested in a development environment before applying to production systems.
Security Considerations
Always ensure proper security measures are in place:
- Regular system updates and patch management
- Firewall configuration and intrusion detection
- SSL/TLS certificate management
- Access control and authentication mechanisms
