mdig
|
|
======
|
|
|
|
multicast dig
|
|
|
|
Create and capture mDNS query and response packets to disk as binary and/or JSON.
|
|
Options are similar to the Unix `dig` command, but for mDNS.
|
|
|
|
See also [dig.js](https://git.daplie.com/Daplie/dig.js)
|
|
|
|
Install with git
|
|
-------
|
|
|
|
```bash
|
|
# Install the latest of v1.x
|
|
npm install -g 'git+https://git@git.daplie.com/Daplie/mdig.git#v1'
|
|
```
|
|
|
|
```bash
|
|
# Install exactly v1.0.0
|
|
npm install -g 'git+https://git@git.daplie.com/Daplie/mdig.git#v1.0.0'
|
|
```
|
|
|
|
Install 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 mdig
|
|
```
|
|
|
|
Usage
|
|
-----
|
|
|
|
### Format
|
|
|
|
```bash
|
|
mdig [TYPE] <query>
|
|
```
|
|
|
|
### Example
|
|
|
|
```bash
|
|
mdig PTR _services._dns-sd._udp.local
|
|
```
|
|
|
|
### defaults
|
|
|
|
When run with no options `mdig` will run with these as the default:
|
|
|
|
```bash
|
|
mdig -p 5353 @224.0.0.251 PTR _services._dns-sd._udp.local +time=3
|
|
```
|
|
|
|
### Non-standard mDNS
|
|
|
|
For debugging you may use a non-standard port and address
|
|
|
|
```bash
|
|
# non-standard port
|
|
mdig -p 1900
|
|
|
|
# non-standard broadcast address
|
|
mdig @239.255.255.250
|
|
```
|
|
|
|
