Hello all..


In my company, i configured the mailserver. That server DNS is the slave DNS server. So i put the records in the Master DNS properly. The Master DNS bind version is bind-8.1.2-5 ( Redhat 7.0). And the slave DNS bind version is bind-9.2.1-16 ( redhat 9.0).

I configured the master DNS properly. But it is not updated the slave files in all slave servers.

But i manually copied slave file from another Slave DNS server and put the system record in that slave file. Then restart the named. DNS is resolving successfully(but not all the system).

The host name of new slave server is "example_bcp.in.example.com".

Kindly please help for this issue.

Thanks

Could you post here your primary's and secondary's DNS named.conf files, so we can help you?

Regards

Dear all..

Really sorry for the Duplicate.

Master named.conf file content
---------------------------------------
// generated by named-bootconf.pl

options {
directory "/var/named";

};

/*zone "." {
type hints;
file "named.ca";
};*/


zone "0.0.127.in-addr.arpa" {
notify yes;
type master;
file "named.local";
};

zone "example.com" {
type master;
file "example.com.hosts";
};

zone "in.example.com" {
notify yes;
type master;
file "named.hosts";
};

zone "16.172.in-addr.arpa" {

};

zone "123.10.in-addr.arpa" {
notify yes;
type master;
file "named.rev.dmz";
};


Slave named.conf file content
---------------------------------------

options {
directory "/var/named";

};

controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
type hint;
file "named.ca";
};

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};

zone "in.example.com" IN {
type slave;
file "named.hosts.slave";
masters {172.16.2.1;};
};

zone "example.com" IN {
type slave;
file "example.slave";
masters {172.16.2.1;};
};

zone "16.172.in-addr.arpa" IN {
type slave;
file "named.rev.slave";
masters {172.16.2.1;};
};

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

Put:
allow-transfer { ns1-IP; ns2-IP;... };
in the options section of your primary named.conf.
You can take a look at /var/log/messages to see if the primary notifies the secondaries about changes and/or if it refuses zone transfers.

hi

I tracked the messages file. It shows like..

"unapproved update from [172.16.2.3].1045 for 16.172.in-addr.arpa"
.....
.....
....
"host name "example_bcp.in.example.com" (owner "xxx.org") IN (primary) is invalid - rejecting"


Thanks

According to bind messages "example_bcp.in.example.com" is an invalid hostname. Check the zone file to correct it.

Hi..

Thanks for your mail. I did give the real company host name. that is just example only. Kindly tell me, is "_" not acceptable in hostname.

You're right. According to rfc 952 "_" is not permitted in a hostname

Hi

Thanking you very much. now it gives the successful result.

I want RFC standards(like RFC 952) guide. If you know any favorite link kindly tell me.

Thanks

I personally use this and
this links. You may find other using google
