# DNSDrone

DNSDrone is a collection of scripts for automatically updating DNS records (A, AAAA, PTR, and TXT) in FreeIPA or standard DNS servers. It supports both Bash environments and Mikrotik routers.

## Features

### Common Features
- Full DNS record management (A, AAAA, PTR, and TXT records)
- IPv6 prefix tracking and updates
- Support for zone apex (root domain) updates
- FreeIPA API integration

### Bash Script Features
- Dual authentication support (FreeIPA user/password or TSIG keys)
- Flexible configuration with environment variables and multiple .env file locations
- Advanced operational modes (debug, dry-run, auto-update)
- Multiple IP provider fallback for reliable address detection
- Automatic updates with version checking

### Mikrotik Script Features
- Native RouterOS integration
- DHCP client-based IP detection
- DoH (DNS over HTTPS) support for TXT record queries
- Cookie-based FreeIPA authentication

## Prerequisites

### For Bash Script
- curl
- jq
- dig
- nsupdate
- [ipcalc or ipcalc-ng](https://gitlab.com/ipcalc/ipcalc) ("ng" for Debian-based distros)

### For Mikrotik Script
- RouterOS with SSH capability
- DHCP client configuration
- Internet connectivity for API access

## Configuration

### Bash Script Configuration
The script looks for a `.env` file in the following locations (in order):
1. Current working directory (`.env`)
2. Script's real path directory (`.env`)
3. Script's real path directory (`.env.<script_name>`)
4. Script's symlink path directory (`.env.<symlink_name>`)
5. `/opt/skyfritt-tools-env/.env.<symlink_name>`

#### Required Variables
| Variable | Description |
|----------|-------------|
| `SERVER` | DNS server hostname or IP address |
| `ZONE_NAME` | DNS zone name (e.g., "example.com") |
| `RECORD_NAME` | Hostname to update (without domain). Skip to update zone apex |

[Rest of the existing configuration documentation remains the same...]

### Mikrotik Script Configuration
Configure the script by modifying the CONFIG dictionary:

```rsc
:local CONFIG {
    "wanInterface"="VLAN666_Altibox";
    "IpaServer"="ipa.demo1.freeipa.org";
    "dnsZone"="demo1.freeipa.org";
    "IpaUser"="admin";
    "IpaPassword"="Secret123";
    "apiVersion"="2.253";
    "recordTTL"="300";
    # [Additional configuration options...]
}
```

## Usage

### Bash Script
```bash
# Basic usage
./dnsdrone.sh

# Debug mode
./dnsdrone.sh -d

# Dry run
./dnsdrone.sh -n

# Check for updates
./dnsdrone.sh -c

# Auto-update
./dnsdrone.sh -a
```

### Mikrotik Script
1. Upload the script to your Mikrotik router
2. Configure the CONFIG dictionary
3. Run manually or schedule via RouterOS scheduler
