bind EINVAL error

[CristianCantoro]

Steps to reproduce

1. Install nvm.
2. Install Node.js version v0.11.14 (nvm install v0.11.14)
3. Install docker-dns: npm install -g docker-dns
4. copy config.js in working directory
5. laundh docker-dns --config config.js

This is the error I get:

$ docker-dns --config 
[...]
[DD] info docker-dns initialized
events.js:85
      throw er; // Unhandled 'error' event
            ^
Error: bind EINVAL
    at exports._errnoException (util.js:742:11)
    at dgram.js:222:28
    at dns.js:82:18
    at process._tickCallback (node.js:372:11)

full debug log here and full config here

fixed in docker-dns 0.2.6 which has just been published to npm

could you please try again and let me know how it goes?

Hi,
I have upgraded docker-dns from npm but I still get the same error.

[~/.docker-dns]$ npm install -g docker-dns
/home/cristian/.nvm/v0.11.14/bin/docker-dns -> /home/cristian/.nvm/v0.11.14/lib/node_modules/docker-dns/bin/docker-dns.js

└── dockerode@2.0.4 (underscore@1.5.2, docker-modem@0.1.19)

Check that the installed version is correct.

$ docker-dns --version                                                      
util.puts: Use console.log instead
docker-dns version 0.2.6

Run docker-dns

[~/.docker-dns]$ docker-dns --config config.js

Funnily enough, launching with the relative path gives me an error:

I can reproduce your results using nvm, but I'm not in a position to start
supporting the v.0.11 development version of nodejs

once v0.12 drops I'll start looking at porting the code, but of course,
only after the dependent libraries are ready.

for the time being, docker-dns works well with v0.10.33

That said, patches are welcome :)
