name: adguard-home description: Manage, troubleshoot, configure, analyze, and review AdGuard Home DNS server. Use when working with AdGuard Home, DNS blocking, ad blocking, network-wide filtering, DNS queries, blocklists, client management, DHCP, or DNS rewrites. Supports REST API and SSH access.

AdGuard Home Management

This skill provides comprehensive management capabilities for AdGuard Home DNS server running on Ubuntu Server.

Prerequisites

Before using this skill, ensure you have:

1. Environment variables configured (in .env or shell):

   ADGUARD_URL=https://your-adguard-domain.local
   ADGUARD_USER=admin
   ADGUARD_PASS=your-password
   ADGUARD_SSH_HOST=192.168.x.x
   ADGUARD_SSH_USER=your-ssh-user
   

2. Python packages installed:

   pip install requests paramiko
   

3. SSH key authentication (recommended) or password access to Ubuntu server

Quick Reference

API Authentication

All API calls use HTTP Basic Auth:

curl -u "$ADGUARD_USER:$ADGUARD_PASS" "$ADGUARD_URL/control/status"

Common Tasks

Core Management Tasks

1. Status & Health Check

Check AdGuard Home status:

python scripts/adguard_api.py status

Or via curl:

curl -u "$ADGUARD_USER:$ADGUARD_PASS" "$ADGUARD_URL/control/status"

2. Query Log Analysis

Analyze DNS queries to troubleshoot issues:

python scripts/adguard_api.py querylog --limit 100 --search "blocked"

Filter by response status: all, filtered, blocked, blocked_safebrowsing, blocked_parental, whitelisted, rewritten, safe_search, processed

3. Filter Management

View current filters:

python scripts/adguard_api.py filters

Add a blocklist:

python scripts/adguard_api.py add-filter --name "My List" --url "https://example.com/blocklist.txt"

Add custom filtering rule:

# Block domain
||ads.example.com^

# Allow domain (whitelist)
@@||allowed.example.com^

# Block with regex
/ads[0-9]+\.example\.com/

4. Client Management

List all clients:

python scripts/adguard_api.py clients

Add/configure client:

python scripts/adguard_api.py add-client --name "Living Room TV" --ids "192.168.1.50"

5. DNS Rewrites

List rewrites:

python scripts/adguard_api.py rewrites

Add rewrite:

python scripts/adguard_api.py add-rewrite --domain "myserver.local" --answer "192.168.1.100"

6. Statistics & Analytics

Get statistics:

python scripts/adguard_api.py stats

Reset statistics:

python scripts/adguard_api.py reset-stats

SSH Server Management

For tasks requiring direct server access:

Service Management

# Check service status
ssh $ADGUARD_SSH_USER@$ADGUARD_SSH_HOST "systemctl status AdGuardHome"

# Restart service
ssh $ADGUARD_SSH_USER@$ADGUARD_SSH_HOST "sudo systemctl restart AdGuardHome"

# View logs
ssh $ADGUARD_SSH_USER@$ADGUARD_SSH_HOST "sudo journalctl -u AdGuardHome -n 100"

Configuration File

Location: /opt/AdGuardHome/AdGuardHome.yaml

# Backup config
ssh $ADGUARD_SSH_USER@$ADGUARD_SSH_HOST "sudo cp /opt/AdGuardHome/AdGuardHome.yaml /opt/AdGuardHome/AdGuardHome.yaml.bak"

# View config
ssh $ADGUARD_SSH_USER@$ADGUARD_SSH_HOST "sudo cat /opt/AdGuardHome/AdGuardHome.yaml"

Update AdGuard Home

ssh $ADGUARD_SSH_USER@$ADGUARD_SSH_HOST "cd /opt/AdGuardHome && sudo ./AdGuardHome -s stop && sudo ./AdGuardHome --update && sudo ./AdGuardHome -s start"

Troubleshooting Guide

See troubleshooting.md for common issues and solutions including:

• DNS resolution failures
• Clients not using AdGuard Home
• High latency issues
• Blocklist update failures
• Service startup problems

Best Practices

See best-practices.md for configuration recommendations including:

• Recommended upstream DNS servers
• Optimal blocklist selection
• Security hardening
• Performance tuning
• Backup strategies

API Reference

See reference.md for complete API endpoint documentation.

Example Workflows

Investigate Blocked Request

1. Check query log for the blocked domain
2. Identify which filter blocked it
3. Add whitelist rule if false positive
4. Clear DNS cache
5. Test resolution

Add New Device with Custom Settings

1. Identify device IP/MAC
2. Create client configuration
3. Set custom upstream DNS if needed
4. Configure blocked services
5. Set parental controls if applicable

Security Audit

1. Review client list for unknown devices
2. Check query log for suspicious domains
3. Verify safebrowsing is enabled
4. Review TLS configuration
5. Check for software updates
