feat: add Pi-hole-like LAN DNS blocking served from the PC (dnsmasq) 
setup_dns_blocker.sh turns this PC into a DNS server that serves the
identical /etc/hosts blocklist to the whole LAN with no per-device app,
by feeding generate_hosts_file.sh output into dnsmasq via addn-hosts
(same StevenBlack variant + custom entries + unblocks). Adds status/
refresh subcommands, a daily refresh timer, Restart=always, and logging
to /var/log/dns-blocker/.

Because the ISP router cannot advertise a custom DNS server, a dhcp/
dhcp-off mode makes the PC the LAN DHCP server (static IP via nmcli with
a gateway-ping self-check and safe, always-online rollback), handing out
itself as the DNS server so every device is blocked automatically.

setup_wireguard_ssh.sh gains an allow-dns subcommand that opens DNS (53,
LAN saddr) and DHCP (67) in the single-owner nftables ruleset. The DHCP
accept rule is placed before 'ct state invalid drop' because the
0.0.0.0->255.255.255.255 DHCP broadcast is classified INVALID and was
otherwise dropped. Firewall detection now reads the actual loaded ruleset
(a ruleset can be loaded while nftables.service reads inactive) and avoids
a grep -q/pipefail SIGPIPE false-negative.

Verified end-to-end: Pixel-6a leased 192.168.1.82 with DNS 192.168.1.43;
youtube.com blocked, legit sites resolve. Regression tests added.

README.md

testsAndMisc

A collection of personal projects, scripts, and experiments — from a GPS-based phone focus tool to Linux/Arch automation, with CI, linting, and pre-commit hooks across the board.

Highlights

Phone Focus Mode

Location-based app restriction for rooted Android. Automatically disables non-whitelisted apps within 500 m of home using ADB + Magisk. Features Haversine distance calculation, hysteresis to prevent toggling, fail-safe unlock, and state persistence. Bash, Android ADB.

Linux Configuration

Automated Arch Linux setup: fresh-install scripts, i3 window manager config, LaTeX environment, and system tests. Includes documentation and test result logging.

Scripts

Utility scripts for development workflows — build file validation, secret detection, and custom makepkg helpers.

Repository Layout

Path Description
python_pkg/ Python packages (each maintained subpackage lives here)
linux_configuration/ Arch Linux setup, i3 config, system maintenance scripts
phone_focus_mode/ GPS-based Android focus enforcer
scripts/ Workspace-level helper scripts and pre-commit hooks
docs/ Reference docs and historical reports
third_party/ Vendored upstream skills/agents
meta/ Repo-wide tooling: pyproject.toml, requirements.txt, .pre-commit-config.yaml, run.sh, lint_python.sh, .fvmrc. Symlinked into the repo root so tools that auto-discover from root keep working.

Archived / unmaintained projects live in the sibling repository testsAndMisc-archive.

Tooling

  • Python linting: Ruff with all rules enabled (see meta/pyproject.toml)
  • Dependencies: pip install -r meta/requirements.txt (combined runtime + dev)
  • CI: GitHub Actions — lint, build, and test on push
  • Testing: pytest (Python), custom shell-based test harness for scripts
