## Problem
|
|
The npm-pihole-sync.sh script at /mnt/NV2/Development/claude-home/server-configs/networking/scripts/npm-pihole-sync.sh is outdated for Pi-hole v6.
|
|
|
|
**What happened:**
|
|
- User removed pd.manticorum.com NPM proxy rule to route through Cloudflare
|
|
- Script synced NPM hosts but didn't remove pd.manticorum.com from Pi-hole DNS
|
|
- Caused continued 502 errors when accessing pd.manticorum.com API
|
|
|
|
**Root Cause:**
|
|
Pi-hole v6 changed DNS record storage:
|
|
- OLD (v5): /etc/pihole/custom.list
|
|
- NEW (v6): /etc/pihole/pihole.toml (dns.hosts array in TOML format) AND /etc/pihole/hosts/custom.list
|
|
|
|
**Manual Fix Applied:**
|
|
ssh pihole "docker exec pihole sed -i '/pd\.manticorum\.com/d' /etc/pihole/pihole.toml /etc/pihole/hosts/custom.list && docker exec pihole pihole reloaddns"
|
|
|
|
**Script Requirements:**
|
|
1. Update /etc/pihole/hosts/custom.list (traditional format)
|
|
2. Update /etc/pihole/pihole.toml hosts array (TOML format: hosts = ["IP DOMAIN", ...])
|
|
3. Use 'pihole reloaddns' instead of 'pihole restartdns reload'
|
|
4. Fix secondary pihole SSH (use IP with -o StrictHostKeyChecking=no instead of hostname)
|
|
|
|
**Challenges:**
|
|
- Pi-hole container has NO python3, NO perl
|
|
- Need pure shell/sed/awk solution
|
|
- TOML hosts array is multi-line regex replacement
|
|
|
|
**TOML Format:**
|
|
hosts = [
|
|
"10.10.0.16 domain1.com",
|
|
"10.10.0.16 domain2.com"
|
|
]
|
|
|
|
**Secondary Pihole:**
|
|
- IP: 10.10.0.226
|
|
- User: cal
|
|
- Need: ssh -o StrictHostKeyChecking=no cal@10.10.0.226
|
|
|
|
**Files:**
|
|
- Script: /mnt/NV2/Development/claude-home/server-configs/networking/scripts/npm-pihole-sync.sh
|
|
- Primary Pi-hole: 10.10.0.16 (pihole container)
|
|
- Secondary Pi-hole: 10.10.0.226 (pihole container)
