    Example session with this skill installed

    I want to deploy my Python bot to my home server HAL-9000. It runs on port 8080. Build me a secure installer.

    • Read your context and instructions
    • Compiled the nex-pi-production-hardening

    I have generated the nex-pi-deploy package for 'python-bot':

    • setup.sh (Hardened installer)
    • python-bot.service (Isolated systemd unit)
    • .env.template
    • rollback.sh

    To deploy, run: scp -r python-bot-deploy pi@hal-9000:~/ && ssh pi@hal-9000 -p 22 'sudo bash ~/python-bot-deploy/setup.sh'

    Connects securely to your tools. The creator never sees your data.

    About this skill

    What it does

    • Configures UFW to deny all inbound by default and open only the ports your services actually need, with rate-limited SSH.
    • Installs fail2ban with an aggressive SSH jail: 3 retries, 3600 second ban, 600 second window.
    • Hardens SSH: no root login, key-only authentication, port 2222, MaxAuthTries 3, no X11 forwarding.
    • Creates dedicated non-root service users and systemd units with restart on crash and journald logging.

    Use cases

    • Putting a Pi on the internet without leaving it wide open
    • Bringing an existing home-lab Pi up to production standard
    • A repeatable hardening baseline across several devices
    • Answering a client question about how their demo host is secured

    Known limitations

    Debian and Raspberry Pi OS specific. It hardens the host, not your application code. Changing the SSH port and disabling password login can lock you out if you apply it without a working key, so read the rollback section first.
