Bu rehber, Raspberry Pi üzerinde çalışan bir Paper (veya benzeri) Minecraft sunucusunun güvenliğini artırmak amacıyla hazırlanmıştır. Aşamalar sıralı ve açıklamalı olarak verilmiştir. Her adımın sonunda neden bu işlemi yaptığımız ayrıca belirtilmiştir. Sisteminize zarar vermemek için işlemleri sırasıyla dikkatle uygulayın.
Sunucuya parolasız, sadece size özel bir SSH anahtarı ile bağlanmak, brute-force saldırılarını tamamen önler.

| There are many tutorials on the web that explain how to build a | |
| simple hello world in C without the libc on AMD64, but most of them | |
| stop there. | |
| I will provide a more complete explanation that will allow you to | |
| build yourself a little framework to write more complex programs. |
