DeepFilterNet
- DeepFilterNet: Server Configuration and Technical Overview
This article details the configuration and technical specifications of the DeepFilterNet server, a critical component of our content delivery infrastructure. This guide is aimed at newcomers to the server administration team and provides a comprehensive understanding of the system. Please read this document carefully before attempting any configuration changes. This server relies heavily on PHP and MySQL, understanding these technologies is vital.
Overview
DeepFilterNet is a dedicated server responsible for advanced content filtering and analysis. It processes all incoming requests, analyzes the content for malicious code, spam, and inappropriate material, and then either allows or blocks the request. It works in tandem with the Load Balancer and the Database Servers to ensure a secure and reliable service. It leverages Lua scripting for custom filtering rules. The server's performance directly impacts the end-user experience, making its correct configuration paramount. Understanding the System Logs is critical for troubleshooting.
Hardware Specifications
The following table outlines the hardware specifications of the DeepFilterNet server:
| Component | Specification |
|---|---|
| CPU | Dual Intel Xeon Gold 6248R (24 cores/48 threads per CPU) |
| RAM | 256 GB DDR4 ECC Registered RAM |
| Storage | 2 x 4TB NVMe SSD (RAID 1) for OS and temporary files 8 x 16TB SAS HDD (RAID 6) for log storage |
| Network Interface | Dual 100Gbps Ethernet |
| Power Supply | Redundant 1600W Platinum Power Supplies |
These specifications allow for high throughput and minimal latency, crucial for real-time content filtering. Proper Disk Management is essential to maintain performance.
Software Configuration
DeepFilterNet runs a customized version of CentOS 7.9. The key software components are detailed below. The Operating System is regularly updated with security patches.
| Software | Version | Purpose |
|---|---|---|
| Operating System | CentOS 7.9 | Server base operating system |
| Web Server | Apache 2.4.6 | Handles incoming HTTP/HTTPS requests |
| PHP | 7.4.33 | Processes filtering scripts and logic |
| MySQL | 8.0.30 | Stores filtering rules, blacklists, and logs |
| Intrusion Detection System | Snort 2.9.18 | Monitors network traffic for malicious activity |
| Anti-Virus Software | ClamAV 0.103.4 | Scans content for viruses and malware |
All software is configured for optimal performance and security. Regular Security Audits are performed to identify and address potential vulnerabilities. The Firewall Configuration is strictly controlled.
Network Configuration
The DeepFilterNet server is located within a dedicated VLAN for security. The following table details the network configuration:
| Parameter | Value |
|---|---|
| IP Address | 192.168.10.10 |
| Subnet Mask | 255.255.255.0 |
| Gateway | 192.168.10.1 |
| DNS Servers | 8.8.8.8, 8.8.4.4 |
| VLAN ID | 10 |
| SSH Port | 22 (restricted access) |
Network access is strictly controlled using Access Control Lists (ACLs) and a stateful firewall. The Network Monitoring system provides real-time visibility into network traffic. The server utilizes SSL/TLS for secure communication.
Troubleshooting Common Issues
- **High CPU Usage:** Investigate PHP scripts and MySQL queries for performance bottlenecks. Utilize tools like `top` and `mysqladmin processlist`.
- **Slow Response Times:** Check network latency, disk I/O, and database performance.
- **Filtering Errors:** Review the system logs for error messages related to filtering rules or anti-virus software.
- **Connection Refusals:** Verify firewall rules and network connectivity.
- **Database Connection Errors:** Check MySQL server status and connection parameters.
Consult the Troubleshooting Guide for more detailed instructions. The Support Team is available for assistance.
Future Enhancements
Planned upgrades include:
- Implementing a more advanced machine learning-based filtering engine.
- Increasing RAM to 512GB.
- Migrating to a newer version of CentOS.
- Integrating with a threat intelligence feed.
