Claude Code no VPS + Hardening do zero (ou quase)

Roteiro para configurar um VPS Ubuntu 24.04 a partir do root até um ambiente endurecido com usuário não-root, SSH key-only, fail2ban, UFW e diretório de deploy pronto.

Otávio aqui: isso foi 99% escrito pelo Claude usando meu DEV_GUIDE de outros vídeos.

SSH Keys Rotation

Since I record my screen a lot for videos and courses, I need to take some security measures more frequently than the average person. Because I recently recorded a few videos teaching Linux server security, I ended up showing some SSH private and public keys on screen.

There’s nothing critical here. Those were temporary keys. Still, just to be safe, I’m rotating all my SSH keys.
