digd.js
=======
| [dns-suite](https://git.daplie.com/Daplie/dns-suite)
| [dig.js](https://git.daplie.com/Daplie/dig.js)
| **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
```

You may also be interested in Unbound (https://unboundtest.com), which is an entirely different project by someone else
which is much more complete, written in go, and may be very useful for debugging and linting.
