Infrastructure

The disqt.com VPS is a Debian server hosted on OVH. This section covers the underlying infrastructure that supports all services.

Key Principles

• User isolation: Each service runs under its own Linux user for security and separation of concerns.
• systemd services: Most long-running processes are managed as systemd units.
• nginx reverse proxy: All HTTP traffic enters through nginx, which routes requests to the appropriate backend.
• SSH on port 24420: SSH access uses a non-standard port for basic security hardening.

Infrastructure Pages

• nginx -- Reverse proxy configuration and routing
• Metrics Monitoring -- Prometheus, Grafana, and exporters
• systemd Services -- Service units and management commands
• Users & Access -- Linux users and SSH configuration
• Kernel Tuning -- Network optimizations for game servers
