I have backed up dns files with tar command from redhat 9, and restore them to centos 5.3 x86, but named has an error as follows;

Code:

[root@myserver _work]# service named start
Starting named: 
Error in named configuration:
zone localdomain/IN: loaded serial 42

 [FAILED]

My dns files are here;

1. named.conf

Code:

 //
// named.conf for Red Hat caching-nameserver 
//myserver.org (named.conf)

options {
        directory "/var/named"; 
        dump-file "/var/tmp/named_dmp.db";
        statistics-file "/var/tmp/named.stats";
        pid-file "/var/run/named/named.pid";
        allow-transfer {203.250.57.28; };     
};

// 
// a caching only nameserver config
// 
controls {
	inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};

zone "." IN {
	type hint;
	file "named.ca";
};

zone "localdomain" IN {
	type master;
	file "localdomain.zone";
	allow-update { none; };
};
zone "myserver.org" IN {
	type master;
	file "myserver.zone";
	allow-update { none; };
};

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 "57.250.203.in-addr.arpa" IN {
        type master;
        file "zone-57.250.203.in-addr.arpa";
};

zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
        type master;
	file "named.ip6.local";
	allow-update { none; };
};

zone "255.in-addr.arpa" IN {
	type master;
	file "named.broadcast";
	allow-update { none; };
};

zone "0.in-addr.arpa" IN {
	type master;
	file "named.zero";
	allow-update { none; };
};

include "/etc/rndc.key";

2. zone-57.250.203.in-addr.arpa

Code:

$TTL    3600
@       IN      SOA             ns.myserver.org. root.myserver.org. (
                                20050309012      ;Serial
                                21600           ;Refresh        ( 6 hours )
                                1800            ;Retry          ( 30 minutes )
                                1209600         ;Expire         ( 14 days )
                                86400 )         ;Minimum        ( 1 day )
        IN      NS              ns.myserver.org.

240     IN      PTR             ns.myserver.org.

Any comment would be appreciated.

At zone-57.250.203.in-addr.arpa,

20050309012 ;Serial

was wrong.

Changed 2005030901 from 20050309012, and fixed.

FYI: You can use a tool called named-checkconf and named-checkzone to check BIND dns server (named daemon) configuration and zone file syntax under Linux / UNIX. It checks the syntax, but not the semantics, of a named configuration file i.e. it can check for syntax errors or typographical errors but cannot check for wrong MX / A address assigned by you. Nevertheless, this is an excellent tool for troubleshooting DNS server related problems.

Glad you got it fixed. This is a really good Deployment guide for RHEL/Centos v5 http://www.linuxtopia.org/online_boo...ion/index.html

Thanks for your kind advice.
