dig.js

| dns-suite | dig.js | 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.

Install with git

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

# Install exactly v1.0.0
npm install -g 'git+https://git@git.daplie.com/Daplie/dig.js.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, dictatornet (as we like to call it here at Daplie Labs), if that's how you roll:

npm install -g dig.js

Usage

Format

dig.js [TYPE] <domainname>

Example

dig.js daplie.com

mDNS Browser Example

This is pretty much an mDNS browser

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:

dig.js -p 5353 @224.0.0.251 PTR _services._dns-sd._udp.local +time=3

Moar Examples

dig.js A daplie.com

dig.js -t A daplie.com

dig.js @8.8.8.8 A daplie.com

Options

--debug
--mdns
--output <path/to/file>     write query and response(s) to disk with this path prefix (ex: ./samples/dns)
-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.
