FragNode 4-Step UDP Port-Forwarding, DDoS Hardening & Save Backup Checklist

We configure every new Linux KVM or Dedicated VDS game node using this four-step FragNode deployment checklist before opening public whitelist slots.

  1. FragNode Step 1: Verify ISP Peering With Looking Glass mtr

    Open your local terminal with Ctrl+Alt+T, run mtr -rwc 50 against the vendor Singapore, Tokyo, Frankfurt, or US Looking Glass IP during evening hours, and inspect hop loss. Ctrl+Alt+T -> 0.0% Loss

  2. FragNode Step 2: Lock Admin RCON, txAdmin & SQL Ports to Loopback

    Allow only gameplay UDP/TCP ports through UFW, bind MariaDB 3306 strictly to 127.0.0.1, and tunnel txAdmin 40120 or Rust RCON 28016 over SSH key authentication. ufw status: active

  3. FragNode Step 3: Enforce 20%–25% Off-Heap Linux Memory Headroom

    On a 16 GB DDR5 host, cap Java heap at -Xms12G -Xmx12G with Java 21 Generational ZGC so 4 GB stays free for Metaspace, Netty sockets, and Linux NVMe pagecache.

  4. FragNode Step 4: Automate Rolling Off-Node World Save Backups

    Schedule 6-hour rolling zstd snapshots of world directories, Level.sav files, and SQL dumps inside CubeCoders AMP or cron before applying SteamCMD or modpack updates.

FragNode Technical Sizing & Hosting FAQ

How does the FragNode 4-zone dedicated game server RAM formula work?

FragNode sums four physical zones: (1) Linux kernel, pagecache, and AMP/SSH daemon reserve (1.5–2.5 GB), (2) idle server binary footprint documented by the game developer (3.0–13.5 GB), (3) linear modpack/plugin/MLO heap (0–300 mods), and (4) concurrent player slots multiplied by an 8% spike buffer, then snaps upward to commercial DDR5 tiers.

Why does FragNode keep 2 GB to 4 GB of host memory outside Java -Xmx?

OpenJDK 21 allocates Metaspace, thread stacks, JIT code cache, and native Netty network buffers outside the Java heap while Linux caches region files in RAM; setting -Xmx equal to 100% of VPS RAM triggers Linux OOM-Killer crashes during raids.

How should guilds verify latency to Singapore, Tokyo, EU, or US regions listed on FragNode?

Because residential fiber peering and subsea cable maintenance shift dynamically, FragNode advises running mtr -rwc 50 against each vendor official Looking Glass IP during peak evening play hours (20:00–23:00 local time) before purchasing.

Where does FragNode source the hosting tier prices shown in the comparison table?

All plan specs and promotional intro prices on FragNode were retrieved from official public vendor pricing pages on 2026-11-12. Always verify live checkout totals and renewal billing cycles on the vendor website.
