Itemsadder - Portable

Cause: Linux and Windows handle port binding differently. On Linux, ports below 1024 require root. Fix: Change the self-host.port to a high number (e.g., 25566) in your portable config. Update the resource-pack= URL accordingly.

Linux (start.sh):

#!/bin/bash
exec java -Xms2G -Xmx4G -jar server.jar nogui

Problem: Texture is missing/Pink and Black checkerboard.

Before diving into the how, let's look at the why. Most server admins treat their ItemsAdder setup as a "dirty" installation—fraught with absolute paths, missing dependencies, and fragmented resource packs.

Let’s look at where this methodology shines: Linux ( start
