| **digd.js**

A lightweight DNS / mDNS daemon (server) for creating and capturing DNS and mDNS
query and response packets to disk as binary and/or JSON.
Options are similar to the Unix dig command.

Install
-------

### with git

```bash
# Install the latest of v1.x
npm install -g 'git+https://git@git.daplie.com/Daplie/digd.js.git#v1'
```

```bash
# Install exactly v1.0.0
npm install -g 'git+https://git@git.daplie.com/Daplie/digd.js.git#v1.0.0'
```

### without git

Don't have git? Well, you can also bow down to the gods of the centralized, monopolized, concentrated, *dictator*net
(as we like to call it here at Daplie Labs), if that's how you roll:

```bash
npm install -g digd.js
```

Usage
-----

```bash
digd.js --input <path/to/file.json>
```

**Example**:

```bash
digd.js --input ./examples/example.com.json
```

### Testing

```bash
# unix dig
dig @localhost example.com

# dns-suite's dig.js
dig.js @localhost example.com

# unix netcat
netcat -u 127.0.0.1 53 < ./samples/example.com.a.query.bin
```

Options
-------

```
--output <path/to/file>     write query and response(s) to disk with this path prefix (ex: ./samples/dns)
--input <path/to/file>      input file to use for authoritative responses (ex: ./samples/zones.json)

--mdns                      Use mDNS port (5353) and nameserver address (224.0.0.251)

-p <port>                   default 53 (mdns default: 5353) (listener is random for DNS and 5353 for mDNS)
--nameserver <ns>           alias of @<nameserver>
--timeout <ms>              alias of +time=<seconds>, but in milliseconds

@<nameserver>               specify the nameserver to use for recursive DNS resolutions (defaults to system defaults)
+time=<seconds>             Sets the timeout for a query in seconds.
+norecurse                  Set `ra` flag to 0. Do not perform recursion.
+aaonly                     Set `aa` flag to 1. Do not respond with non-authoritative responses.

--debug                     verbose output
```

which is much more complete, written in go, and may be very useful for debugging and linting.
