Re: [gentoo-user] DNS Expert Required

You might want to set your serial to a date format like:
2006032600

When you do an update on the same day you just increment the last 
digit(s).

2006032601

You are more likely to remember when you have done updates with a date.

Hi Uwe,

The main problem in my configuration was this:
search server1.guru.com server2.guru.com
search guru.com
zone "server1.guru.com" IN {
make this: zone "guru.com" IN {

After changing this, my dns server is working fine. Thanks a lot dude.

Some small errors.

server1.guru.com (192.168.0.2)  Primary DNS Server
server2.guru.com (192.168.0.3)  Secondary DNS Server

=> Here is my configuration file for server1.guru.com machine.

#######################/etc/resolve.conf##############################
domain guru.com
search server1.guru.com server2.guru.com

search guru.com

(the search string gets appended to non-qualified names)

allow-tansfer: take out 192.168.0.1; it's unnecessary.

make this: file "guru.com";   (not strictly necessary)

 allow-query { any; };

In the general options, you restrict queries to your local network. Why do
you
now allow queries from anywhere?

 allow-update { key rndckey; };
};



#include "/etc/rndc.key";
######################################################################

make the file "guru.co"

$TTL 86400
@ IN SOA server1.guru.com. root.server1.guru.com. (

BTW, *not* a good idea to make "root" the technical contact for your
domain.

Now most stuff below can be much easier.
    1          ; serial
    300    ; refresh (5 minutes)
    10         ; retry (10 seconds)
    86400      ; expire (1 day)
    600        ; minimum (10 minutes)
    )

@ IN NS server1.guru.com.
@ IN MX 10 server1.guru.com.

server1.guru.com. IN A 192.168.0.2
server2.guru.com. IN A 192.168.0.3
win2k.guru.com.  IN A 192.168.0.1

www1   CNAME server1.guru.com.
www2   CNAME server2.guru.com.
www3   CNAME win2k.guru.com.

server2 IN MX 0 server1.guru.com.
win2k IN MX 0 server1.guru.com.

The lines above can now look this way:

       IN      NS      server1.guru.com.
       IN      NS      server2.guru.com.

       IN      MX      10      server1.guru.co.
*.guru.com      IN      MX      10      server1.guru.com.

server1 IN      A       192.168.0.2
server2 IN      A       192.168.0.3
win2k   IN      A       192.168.0.1

www1    CNAME   server1
www2    CNAME   server2
www3    CNAME   win2k

(Note where I put a fullstop at the end of a name and where not. It's
important. Your MX statements above are contradictory. So I don't know
exactly which box your email server is and if you really have more than
one.
If so you have to adjust my two MX entries above.)

Adjust server2 accordingly.

I cannot guarantee that I caught all mistakes. Just try it out.
