setup - one primary dns and one slave dns. zone transfer works, internet works, dig lookup works. if i bring down the primary, everything stops working. slave dns config below. thnx in advance

zone "2.168.192.in-addr.arpa." IN {
type slave;
file "slaves/192.168.2.db";
masters { 192.168.2.5 port 53;
};
};
zone "aaa.com." IN {
type slave;
file "slaves/aaa.com.db";
masters { 192.168.2.5 port 53;
};
};
options {
listen-on port 53 { 127.0.0.1; };
listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { localhost; };
recursion yes;

dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;

/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";

managed-keys-directory "/var/named/dynamic";
};

logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};



include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

primary and slave dns in the same server ?
otherwise please look at /var/log/messages
in slave server

/var/log/messages no error messages. this is from the slave machine

dig aaa.com

This is because the slave is listening on the local loopback inteface only and it only allows queries from localhost.
