| [dns-suite](https://git.daplie.com/Daplie/dns-suite) | **dig.js** | [digd.js](https://git.daplie.com/Daplie/digd.js) |
|
|
|
|
Create and capture DNS and mDNS query and response packets to disk as binary and/or JSON.
|
|
Options are similar to the Unix `dig` command. Supports dns0x20 security checking.
|
|
|
|
Install
|
|
-------
|
|
|
|
### with git
|
|
|
|
```bash
|
|
# Install the latest of v1.x
|
|
npm install -g 'git+https://git.daplie.com/Daplie/dig.js.git#v1'
|
|
```
|
|
|
|
```bash
|
|
# Install exactly v1.0.0
|
|
npm install -g 'git+https://git.daplie.com/Daplie/dig.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 dig.js
|
|
```
|
|
|
|
Usage
|
|
-----
|
|
|
|
```bash
|
|
dig.js [TYPE] <domainname>
|
|
```
|
|
|
|
**Example**:
|
|
|
|
```bash
|
|
dig.js daplie.com
|
|
```
|
|
|
|
### mDNS Browser Example
|
|
|
|
This is pretty much an mDNS browser
|
|
|
|
```bash
|
|
dig.js --mdns _services._dns-sd._udp.local
|
|
```
|
|
|
|
Really the `--mdns` option is just an alias for setting all of these options as the default:
|
|
|
|
```bash
|
|
dig.js -p 5353 @224.0.0.251 PTR _services._dns-sd._udp.local +time=3
|
|
```
|
|
|
|
### Moar Examples
|
|
|
|
```bash
|
|
dig.js A daplie.com
|
|
|
|
dig.js @8.8.8.8 A daplie.com
|
|
```
|
|
|
|
Options
|
|
-------
|
|
|
|
```
|
|
--output <path/to/file> write query and response(s) to disk with this path prefix (ex: ./samples/dns)
|
|
|
|
--mdns Use mDNS port and nameserver address, and listen for multiple packets
|
|
|
|
-t <type> (superfluous) default ANY (mdns default: PTR)
|
|
-c <class> default IN
|
|
-p <port> default 53 (mdns default: 5353) (listener is random for DNS and 5353 for mDNS)
|
|
-q <query> (superfluous) required (ex: daplie.com)
|
|
--nameserver <ns> alias of @<nameserver>
|
|
--timeout <ms> alias of +time=<seconds>, but in milliseconds
|
|
|
|
@<nameserver> specify the nameserver to use for DNS resolution (defaults to system defaults)
|
|
+time=<seconds> Sets the timeout for a query in seconds.
|
|
+norecurse Set `rd` flag to 0. Do not request recursion
|
|
+aaonly Set `aa` flag to 1.
|
|
|
|
--norecase Disable dns0x20 security checking (mixed casing). See https://dyn.com/blog/use-of-bit-0x20-in-dns-labels/
|
|
--recase Print the dns0x20 casing as-is rather than converting it back to lowercase. This is the default when explicitly using mixed case.
|
|
|
|
--debug verbose output
|
|
```
