Secrets

• Encrypted secrets file. All repo-managed credentials live in secrets/secrets.yaml, encrypted with SOPS/age.
• Encrypted OpenTofu state. State and plans are encrypted client-side (PBKDF2 + AES-GCM) with a passphrase from TF_VAR_state_passphrase.

Network perimeter

• Default-drop firewall on the router. I use a hand-written nftables ruleset with policy drop on both input and forward. Only lo, lan0 and wg0 are trusted. WAN accepts only established traffic, WireGuard UDP and HTTP/HTTPS.
• No SSH from the WAN. sshd on the router is not exposed to the internet at all.
• WireGuard for remote access.
• Forced DNS. NAT redirects all LAN and VPN port-53 traffic to the router’s AdGuard. AdGuard uses Quad9 over DoT upstream, with blocklists and safe search.
• Second-level ACL in nginx. Private .home vhosts and Grafana carry allow LAN; allow VPN; deny all;.
• TLS everywhere. Every public vhost sets forceSSL with recommendedTlsSettings. Certificates come from ACME DNS-01, so issuance needs no inbound port 80. Cloudflare is DNS-only with no proxy, so no third party sees plaintext.

Host access

• SSH hardening. Password and keyboard-interactive auth are off, PermitRootLogin = “no”, and logins are key-only.
• Dedicated deployer system user. It uses a CI-only keypair, separate from the interactive keys. Everything it does through sudo is logged with LOG_INPUT/LOG_OUTPUT to /var/log/sudo-deployer.log.

Thanks for sharing. I’m trying it out as a Google Keep replacement.

Copyparty. Or any other web file server.

Yeah so at worst you could get sued by some random reddit users that don’t want their post history hosted on your site.

Given how little traction artists and authors have had with suing AI companies for blatant copyright infringement, I kinda doubt it would go anywhere.
