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

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

# 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, dictatornet (as we like to call it here at Daplie Labs), if that's how you roll:

npm install -g digd.js

Usage

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

Example:

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

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
