Fun DNS server  build on top of Nodejs

How install
	Run $ sudo setup.sh
OR
	$ wget -O /tmp/fun_dns.tar.gz https://github.com/downloads/badlee/fun-dns/fun_dns.v0.1.12.tar.gz
	$ sudo -s 
	$ mkdir /opt/fun_dns
	$ cd /opt/fun_dns
	$ tar xvf /tmp/fun_dns.tar.gz
	$ ln -s /opt/fun_dns/fun_dns.daemon /etc/init.d/fun_dns
	$ update-rc.d fun_dns defaults
	$ #Start service
	$ service fun_dns start

How define hostname
	edit 'config/conf.json',
	the syntaxe of this file respect json format
		{
			"hostname1" : {
				[property...]
			},
			"hostname2" : {
				[property...]
			},
			"hostname3" : {
				[property...]
			},
			[...]
			"hostnameN" : {
				[property...]
			}
		}
	properties of a hostname
		"name" : {
			"ip" : "127.0.0.1",
			"description" : "je suis le serveur web local",
			"autority" : "dns.{name},admin@{name}",
			"mail" : {
				"ip" : "127.0.0.2",
				"name" : "mail.{name}",
				"priority" : 10
			},
			"nameserver" : [{
				"ip" : "127.0.0.1",
				"name" : "ns1.{name}"
			}]
		}
	The hostname can have a short regex like syntaxe.
		*  : this expression respect ".*" in regex;
		%w : this expression respect "[a-zA-Z0-9_]+" in regex;
		%h : this expression respect "[a-fA-F0-9]+" in regex;
		%d : this expression respect "[0-9]+" in regex;

	sample conf.json :
		{
			"server.web" : {
				"ip" : "192.168.1.3",
				"nameserver" : [{
					"name" : "dns3.local.web"
				},{
					"ip" : "192.168.1.2",
					"name" : "dns2.local.web"
				},{
					"ip" : "192.168.1.1",
					"name" : "dns.local.web"
				}]
			},
			"!*.lo" : {
				"ip" : "127.0.0.1",
				"autority" : "dns.{name},admin@{name}",
		
				"nameserver" : [{
					"ip" : "127.0.0.1",
					"name" : "dns.{name}"
				},{
					"ip" : "127.0.0.1",
					"name" : "dns2.{name}"
				}]
		
			}
		}

Server confiurations(config/serv.ini)
	conf = configuration hostname file(if not defined is set to app://config/conf.json)
	host = your ip4 addresse to listen(if not defined listen all)
	port = port to listen(if not defined listen 53)
	Section nameserver = list of dns server used to found response when no response found on server(as a proxy, but it's eprouve the global performances)
	[nameserver] 
		nameOfTheDnsServer1 = Ip_Address
		nameOfTheDnsServer2 = Ip_Address
		...
		nameOfTheDnsServer3 = Ip_Address
	Section ttl = list of ttl in dns reponse (in secondes)
	[ttl]
		ip  = ttl for any ip (A or AAAA) address (if not defined 77)
		ttl = ttl for any field different of ip (A or AAAA) (if not defined 600)
		refresh = time to refresh the zone (if not defined 1800)
		retry   = time to retry when refresh (above) has expired (if not defined 900)
		expiration = ttl for DNS response (if not defined 604800)

	sample serv.ini:
		conf = app://config/lab.json
		port = 53
		host = 192.168.1.1
		spf  = "v=spf1 +all"
		[ttl]
		    ttl = 600
		    ip  = 77
		[nameserver]
		    google.dns.a = 8.8.8.8
		    google.dns.b = 8.8.4.4
