[joydeep]

Dear forum,

I have again come back to you with a big confusion about creating own DNS.
I have a remote root server say it is myserver.domain.com

now there is no MX record for domain.com hence I can't get any mail for user@domain.com
That's why I like to create my own DNS on that server with MX record.
I have created a master  zone  by webmin as joydeep.edu  and below is its config

-----------------------------------------
$ttl 38400
joydeep.edu.   IN   SOA   joydeep.edu. joydeep.infoservices.in. (
         2007042509
         10800
         3600
         604800
         38400 )
joydeep.edu.   IN   A   87.230.8.228
www.joydeep.edu.   IN   A   87.230.8.228
mail.joydeep.edu.   IN   A   87.230.8.228
ns1.joydeep.edu.   IN   A   87.230.8.228
ns2.joydeep.edu.   IN   A   87.230.8.228
joydeep.edu.   IN   NS   ns1.joydeep.edu.
joydeep.edu.   IN   NS   ns2.joydeep.edu.
joydeep.edu.   IN   MX   10 mail.joydeep.edu.
------------------------------------------------------------

and I also loaded it by webmin.  now  " host joydeep.edu"    reports
Host joydeep.edu not found: 3(NXDOMAIN)

So how can I fix it ? where is the problem ?
please help me.  thanks

I am not yet expert in DNS stuff, Gaurav can guide you better

For me also DNS in linux is somewhat difficult to implement

Just try the file mentioned below:

$TTL 2D
@      IN SOA      lan.joydeep.edu.   root.lan.joydeep.edu. (
            2005051300   ; serial
            3H      ; refresh
            1H      ; retry
            1W      ; expiry
            1D )      ; minimum

joydeep.edu.     IN NS      lan.joydeep.edu.
                            IN NS                www.joydeep.edu.
                            IN MX 10            mail.joydeep.edu.
lan        IN A       87.230.8.228
www                     IN A                  87.230.8.228
mail                       IN A                  87.230.8.228
ns1                        IN CNAME              www


Just copy it and make it forwader file , Try and let me know


then ping or host lan.joydeep.edu

or host ns1

I'm not sure if this was resolved or not. DNS in linux is actually fairly easy to implement once you understand the concept. Also the utilities dig and nslookup are critical to determining if your DNS setup is working or not.

Code:

$TTL 3600
@                       IN      SOA     ns1.joydeep.edu. root.joydeep.edu (
                                        2007113001      ; serial (version)
                                        3600            ; 1H refresh period
                                        600             ; 10M retry refresh this often
                                        2592000         ; 4W expiration period
                                        1800 )          ; 30M minimum TTL
                        IN      NS      ns1
                        IN      NS      ns2
                        IN      MX 10   mail
joydeep.edu. IN      A       87.230.8.228
ns1                     IN      A       87.230.8.228
ns2                     IN      A       87.230.8.228
mail                    IN      CNAME   joydeep.edu.
www                     IN      CNAME   joydeep.edu.

The second line IN SOA ... defines the nameserver and email to use if there are problems. So root.joydeep.edu corresponds to root@joydeep.edu.

Most domain registars require you to use two nameservers. Technically these should point to two different IPs but will probably work just fine pointing both to one.

You shouldn't use a CNAME for a name server, it needs to point directly to an IP.

To verify run the commands

Code:

dig mx joedeep.edu @localhost
dig joedeep.edu @localhost

Dig allows you to use @ to specify the DNS server to use. This way you can test your DNS changes before the propagation takes place.
