Diagnosed azcomputerguru.com 521 errors: Cox's BGP route to specific Cloudflare origin-pull prefixes (162.158.0.0/16, 172.64.0.0/13, 173.245.48.0/20, 141.101.64.0/18) is broken from 72.194.62.0/29. Confirmed by TCP probe matrix from pfSense WAN, traceroute latency comparison, and state-table showing 0 inbound CF connections while direct-internet traffic still reached origin. Deployed Cloudflare Tunnel 'acg-origin' on Jupiter Unraid as a Docker container. Routes 4 proxied hostnames (azcomputerguru.com, analytics., community., radio.) through the tunnel with HTTPS backend to IX 172.16.3.10:443 with per-ingress SNI matching. All 4 hostnames return 200 OK through CF edge after the cutover. Repo hygiene: - Merged clients/ix-server/ into clients/internal-infrastructure/ (IX is internal infra, not a paying-client account). Git detected the session-log files as renames so history is preserved. Updated 4 stale path references in 2 files. - Moved cox-bgp ticket draft out of projects/dataforth-dos/ (wrong project) to clients/internal-infrastructure/vendor-tickets/. - Relocated tunnel-setup helper scripts from projects/dataforth-dos/datasheet-pipeline/implementation/ to clients/internal-infrastructure/scripts/cloudflared-tunnel-setup/. Deleted superseded/abandoned login attempts. Sanitized hardcoded Jupiter/pfSense SSH passwords to pull from SOPS vault at runtime; Cloudflare token reads from env var (tokens still in 1Password, vault entry is metadata-only).

Session Log: April 11, 2026
Session Summary
Work Accomplished
-
Radio Show Prep Creation (Multiple Weeks)
- Created show prep for April 5, 2026 (serious AI theme)
- Created show prep for April 11, 2026 (serious theme with Artemis II splashdown)
- Created show prep for April 18, 2026 (light and fun theme - per user request)
- Generated HTML versions with clickable source links for April 11 and April 18 shows
- All show preps follow 4-segment format (12-16 minutes each)
-
IX Server Security Audit
- Scanned 87 WordPress installations for Smart Slider 3 Pro plugin
- Response to supply chain attack (April 7-9, 2026)
- Found 0 PRO versions (compromised), 3 FREE versions (safe)
- Created scan script and comprehensive security report
- Risk assessment: LOW - no exposure to attack
-
Local Network Scanning
- Scanned 192.168.0.0/24 network for MAC address ending in B8:56
- Found 2 Yealink VoIP devices (192.168.0.40, 192.168.0.47)
- Scanned entire network for devices with port 81 open (none found)
-
Domain Controller Guidance
- Provided PowerShell and Group Policy methods for granting "Log on as batch job" rights
- SeBatchLogonRight configuration for batch processing
Key Decisions
-
Show Prep Theme Evolution
- Initial serious/heavy topics (AI costs, security, infrastructure)
- User explicitly requested "more light and fun" content
- Shifted to positive tech: CES gadgets, gaming, helpful AI, medical breakthroughs
- Maintained journalistic integrity while focusing on uplifting stories
-
Security Scan Approach
- Used filesystem-based scan rather than database queries
- Scanned all cPanel accounts for wp-config.php files
- Distinguished between PRO (compromised) and FREE (safe) versions
- Created reusable scan script for future security audits
-
Network Scanning Strategy
- Initially attempted ARP cache lookup (timeout issues on Mac)
- Switched to direct IP-based SSH connection to IX server
- Used Python concurrent futures for port scanning with proper timeout handling
Problems Encountered and Solutions
-
ARP Command Timeout
- Problem:
arp -ahanging when used with heredoc on Mac - Solution: Switched from hostname to direct IP (172.16.3.10)
- Alternative: Used Python subprocess with timeout handling
- Problem:
-
Background Task Management
- Problem: Multiple background bash tasks (b9a7949, be1386b) failed/timed out
- Solution: Used direct SSH with proper connection methods
- Result: Successful connection to IX server via IP
-
Port 81 Scan Initial Failure
- Problem: Netcat scan running in background but timing out
- Solution: Created Python concurrent futures scan with timeout
- Result: Confirmed no devices with port 81 open on network

Notes for Future Sessions
Show Prep Preferences
User prefers:
- Light and fun content for audience engagement
- Positive tech stories (gadgets, gaming, helpful AI, medical breakthroughs)
- Mix of segments covering different tech areas
- Avoid heavy/serious doom-and-gloom topics when possible
- HTML versions with clickable source links for web reference
Security Scanning Best Practices
-
Plugin Update Policy:
- Wait 24-48 hours after updates released before applying to production
- This delay would have avoided the 6-hour Smart Slider attack window
-
Regular Audits:
- Schedule quarterly plugin audits
- Check for outdated/abandoned plugins
- Remove unused plugins (smaller attack surface)
-
Backup Strategy:
- Ensure all 87 WordPress sites have current backups
- Test restore procedures
- Keep backups isolated from production
Network Scanning Notes
- Local network: 192.168.0.0/24
- Mac ARP cache sometimes needs direct IP instead of hostname
- Python concurrent futures works well for port scanning with timeout
- MAC vendor lookup API: http://api.macvendors.com/
