SSH Access Through Tailscale Behind a Cloud Firewall

Lock down SSH with Tailscale as your primary path — encrypted WireGuard mesh, accessible from anywhere without exposing a public port. Two direct fallbacks from known home IPs for when the mesh is down, enforced at the cloud firewall level. Three paths in. No port scanners allowed.

Automated Off-Site Backups with rclone

rclone to Proton Drive, a home server over Tailscale, or any provider that speaks SFTP — with cron scheduling, age-based pruning, and a reminder that cloud convenience is not a backup strategy. One dump per database, one target automatic, one independent. What to back up, what to skip, and why provider snapshots aren't the same thing.

Blocking Direct-to-Origin Access with a Cloud Firewall

Stop port scanners and direct-to-IP attacks before they reach your server. A stateless cloud firewall — free on most providers — drops all traffic on ports 80 and 443 that doesn't originate from Cloudflare's IP ranges. Includes the certificate renewal caveat: every domain on your Let's Encrypt certificate must be proxied, or renewal breaks.

Bludit Pro 3.22.0: A Production Stability Audit

Before deploying Bludit Pro to a live site, I read the source code. Nine findings later — including a predictable preview token that exposed draft content — here's what I patched in my own build and why it matters for anyone running the same CMS.

Fail2ban with nftables and Crowd-Sourced Blacklists

Set up fail2ban for SSH and Nginx with AbuseIPDB reporting, incremental bans, and daily blacklist imports from AbuseIPDB, Bitwire, and Spamhaus — a layered defense that catches bots before they reach your application.
