I have just installed locally SkyDNS and I am not resolve the IP address from a Node's dns lookup. My resolv.conf has only one entry:
nameserver 127.0.0.1
result from dig:
$ dig service.skydns.local
; <<>> DiG 9.9.5-3ubuntu0.8-Ubuntu <<>> service.skydns.local
;; global options: +cmd

When I try to resolve using Node's dns lookup:
var dns = require('dns');
dns.lookup('service.skydns.local', function(err, res, fam){console.log(err, res, fam);})
{ [Error: getaddrinfo ENOTFOUND service.skydns.local]
code: 'ENOTFOUND',
errno: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'service.skydns.local' } undefined undefined
Using resolve4 instead of lookup it works, but why won't lookup resolve this address from the local dns?
Changing the priority of dns at /etc/nsswitch.conf it works:
hosts: dns files
