    Configurare DNS Server senza ausilio di pannelli di controllo

    Ciao,

    la mia situazione è questa ho un server dedicato con Fedora Core 6, ho installato LightTPD, e fino a qua tutto ok.
    Il mio problema è quello di configurare correttamente gli ZONE file per far funzionare tutto a regime con il mio nome di dominio. Per fare questo ho cominciato ad aggiungere al mio file named.conf:

    
zone "mywebsite.net" {
    type master;
    file "/var/named/mywebsite.net.db";
};

   
zone "ns1.mywebsite.net" {
        type master;
        file "/var/named/ns1.mywebsite.net.db";
};
   
zone "ns2.mywebsite.net" {
        type master;
        file "/var/named/ns2.mywebsite.net.db";
};


```I file inclusi nel named.conf sono qui di seguito indicati:

mywebsite.net.db

    ; Zone file for mywebsite.net
    $TTL 14400
    @ 86400 IN SOA ns1.mywebsite.net. admin.fastwebnet.com. (

    Per concludere ho registrato i miei DNS prezzo il mio registrar ed ora purtroppo sono nelle canne, infatti funziona solo l' NS1

    http://www.mywebsite.net --> non va
    http://ns1.mywebsite.net --> funziona
    http://ns2.mywebsite.net --> non va

    Qualcuno che mi sa aiutare ?

Grazie


Thanks in advance for any suggestion

    ti rispondo anche se non sono ferratissimo in DNS .
    Per quello che ho capito io i DNS devi impostarli solo se hai una rete locale e un server centrale dove ci sono i DNS.
    Se hai un solo server remoto non ne hai bisogno (chi interroga il tuo DNS?, solo la macchina locale).
    spero di aver detto giusto
    ciao

    quella configurazione è sbagliata, ecco perchè non funziona

    suppongo tu stia usando bind, in questo caso devi aggiungere al file /etc/named.conf

    
zone "mywebsite.net" IN {
	type master;
	file "mywebsite.net.zone";
};

    e poi creare il file mywebsite.net.zone in /var/named e metterci questo

    
$TTL	604800
@	IN	SOA	ns1.mywebsite.net.   admin.mywebsite.net. (
			2007031001
			43200 
			7200 
			2419200 
			604800); fine SOA
;
@	IN	NS	ns1
	IN	NS	ns2
	IN	A	IP del webserver
	IN	MX	10	mail
; servers
ns1	IN	A	IP del DNS primario
ns2	IN	A	IP del DNS secondario
www	IN	A	IP del webserver
ftp	IN	A	IP del server FTP
mail	IN	A	IP del mail server
*.miosito.com.	IN	A	IP del webserver

    alcuni parametri possono variare ma l'ossatura è questa.....inoltre bisogna che nel pannello di controllo del dominio vengano specificati i nuovi DNS server....suppongo che tu abbia bind che gira sul tuo server, e sullo stesso server hai anche il webserver, il mailserver, il server FTP, ecc..... in questo caso i vari IP corrispondono all'IP del server

    non vanno creati file di zona per i DNS server, in quanto questi ultimi devono essere specificati in maniera esplicita ( scrivendo url e IP ) nel pannello di controllo apposito che il registrar del dominio ti ha fornito
