LAN OSMS Service

Overview

This project is a LAN-only MapleStory v83 server hosted inside my Proxmox homelab. The goal is creating a dependable private service for local sessions, while practicing real ops habits: clean networking, safe restarts, backups and recoverability.

Design Goals

• LAN-only by default
• Fast recovery (restart scripts, systemd services, VM snapshots)
• Simple onboarding for players

Architecture

Hosting model

• Dedicated VM for the server workload
• Database stored on the VM (with backups) to keep failure domains obvious

Networking & access

• Server is reachable only on the local network
• Local DNS entry so clients don't need to remember IPs
• Firewall rules to keep the blast radius small

Operations

Service management

• Server processes managed via systemd
• Logs captured for quick diagnosis (start failures, port binds, DB connectivity)

Backups & safety

• Scheduled DB backups (and occasional manual backups before patching)
• VM snapshots before configuration changes or upgrades
• Restore drills (because backups don't count unless you can restore)
