📝 Walkthrough

Walkthrough

Added comprehensive NordVPN setup documentation and a new bootstrapper watchdog script that validates and configures the NordVPN daemon, login status, Meshnet enablement, exit-node permissions, and IP forwarding. Enhanced existing scripts with stricter error handling and documentation fixes.

Changes

NordVPN Setup & Watchdog Infrastructure

Layer / File(s)	Summary
Documentation and device setup reference bash/nord/README.md	New README documents available NordVPN command scripts (login.sh, logout.sh, config.sh, etc.), lists devices running NordVPN, and notes that raspberry is configured as an exit-node for routing traffic from other devices.
Watchdog bootstrapper and daemon initialization bash/nord/nord_watchdog.sh	New script automates NordVPN setup: verifies/starts the nordvpnd daemon via systemctl, confirms login status by parsing nordvpn status output, enables Meshnet via nordvpn set meshnet on, grants exit-node permissions by invoking nordvpn meshnet peer allow-exit-node set, and enables kernel IP forwarding via /proc/sys/net/ipv4/ip_forward.
Config script validation and error handling bash/nord/config.sh	Adds set -euo pipefail for strict Bash error handling and preflight check that nordvpn CLI exists in PATH, exiting with error if missing.
Help output and script maintenance bash/nord/exit_node.sh, bash/nord/status.sh	Corrects example text in exit_node.sh display_help() output; removes executable commands from status.sh, leaving it empty for future use.

Possibly Related PRs

• terjeinnerdal/scripts#4: Updates to bash/nord/config.sh (error handling/dependency checks) and bash/nord/exit_node.sh (usage/help) are directly tied to the same NordVPN configuration/exit-node setup, with the new nord_watchdog.sh automating the logged-in + Meshnet + allow-exit-node flow introduced in that PR.
• terjeinnerdal/scripts#7: Both PRs modify bash/nord/config.sh—main PR adds set -euo pipefail and CLI dependency checks, while PR #7 adds Meshnet/nickname/peer auto-connect setup—creating a direct code-file overlap.
• terjeinnerdal/scripts#11: Both PRs modify bash/nord/config.sh, with the main PR adding strict error handling and dependency validation, while PR #11 adds Meshnet nickname auto-resolution logic.

Poem

🐰 A watchdog hops through tunnels deep,
Meshnet enabled, exit node set,
IP forwarding wakes from sleep,
NordVPN ready—the finest setup yet! 🕳️✨
