Top 6 Shell ufw Projects

ufw

  1. ufw-docker

    To fix the Docker and UFW security flaw without disabling iptables

    Project mention: Announcing udwall: A New Tool for Making UFW and Docker Play Nice With Each Other | dev.to | 2025-11-23

    Complex Uninstall: Historically, removing the tool was risky. It required manually stripping iptables rules, and doing it wrong could lock you out of your server. > Note: ufw-docker recently added an uninstall command.

  2. AppSignal

  3. ufw-blocklist

    IP blocklist extension for Ubuntu ufw firewall

  4. vps-harden

    Idempotent VPS hardening for Ubuntu — SSH, firewall, fail2ban, kernel tuning, auditd, SOPS secrets, and optional AI agent workspace security. Dry-run first, lockout protection built in. (by ranjith-src)

    Project mention: Show HN: VPS-Harden, an Idempotent Bash Script to Harden Ubuntu VPS – OpenClaw | news.ycombinator.com | 2026-02-16

    Zero dependencies — single Bash file, no Python, no Ansible, no agents. curl | bash to install, sudo vps-harden to run.

    The lockout protection was the hardest part to get right. The script disables password auth and restricts SSH to a single user, so if the key deployment or AllowUsers config is wrong, you're locked out.

    It validates everything before reloading sshd, and if validation fails, it removes the config and rolls back.

    Your existing session stays alive throughout.

    Install: curl -fsSL https://raw.githubusercontent.com/ranjith-src/vps-harden/mai... | bash

    Repo: https://github.com/ranjith-src/vps-harden

      Happy to answer questions about the design decisions or trade-offs.

  5. Linux-Hardening-Script

    This shell script hardens the system from profiling and DDOS attacks.

  6. dynamic-dns-in-firewall

    Automatically set traffic rules for Dynamic IP Addresses from a Dynamic DNS Domain

  7. ShellDeck

    Smart shell bootstrap and infra dashboard for fresh VMs, homelabs, and workstations.

    Project mention: Why I Stopped Maintaining Dotfiles and Built a Cross-Platform Shell Bootstrap | dev.to | 2026-06-26
