Mike Swanson a78fb96f95 Session log: Cloudflare Tunnel for azcomputerguru + Cox BGP diagnosis
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  Deleted superseded/abandoned login attempts.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

  1. 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)
  2. 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
  3. 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)
  4. Domain Controller Guidance

    • Provided PowerShell and Group Policy methods for granting "Log on as batch job" rights
    • SeBatchLogonRight configuration for batch processing

Key Decisions

  1. 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
  2. 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
  3. 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

  1. ARP Command Timeout

    • Problem: arp -a hanging when used with heredoc on Mac
    • Solution: Switched from hostname to direct IP (172.16.3.10)
    • Alternative: Used Python subprocess with timeout handling
  2. 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
  3. 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

  1. 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
  2. Regular Audits:

    • Schedule quarterly plugin audits
    • Check for outdated/abandoned plugins
    • Remove unused plugins (smaller attack surface)
  3. 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/
