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
