I have done all that correctly. but the problem exists. Now i tried to re-configure it all--
Now My internal IP is 192.168.70.1
I wanna configure DNS for users in my subnet (internally).
The hostname is -- myserver.dypcoe.com
domainname-- dypcoe.com
entries in named.conf are:--
options {
listen-on port 53 { any; };
# 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";
query-source port 53;
query-source-v6 port 53;
allow-query { any; };
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localdomain" IN {
type master;
file "localdomain.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 "dypcoe.com" IN {
type master;
notify no;
file "dypcoe.com.zone";
allow-query { any; };
};
zone "0.168.192.in-addr.arpa" {
type master;
notify no;
allow-query { any; };
file "192.168.0.zone";
};
listen-on port 53 { any; };
# 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";
query-source port 53;
query-source-v6 port 53;
allow-query { any; };
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localdomain" IN {
type master;
file "localdomain.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 "dypcoe.com" IN {
type master;
notify no;
file "dypcoe.com.zone";
allow-query { any; };
};
zone "0.168.192.in-addr.arpa" {
type master;
notify no;
allow-query { any; };
file "192.168.0.zone";
};
The zone file for dypcoe.com (forward lookup) is--
$TTL 86400
@ IN SOA myserver.dypcoe.com. root.dypcoe.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS www
myserver.dypcoe.com. IN A 192.168.70.1
@ IN SOA myserver.dypcoe.com. root.dypcoe.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS www
myserver.dypcoe.com. IN A 192.168.70.1
The zone file for 192.168.0.x is---
$TTL 86400
@ IN SOA myserver.dypcoe.com. root.myserver.dypcoe.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS myserver.dypcoe.com.
1 IN PTR myserver.dypcoe.com.
@ IN SOA myserver.dypcoe.com. root.myserver.dypcoe.com. (

3600000 ; Expire
86400 ) ; Minimum
IN NS myserver.dypcoe.com.
1 IN PTR myserver.dypcoe.com.
dhcp is configured accordingly in dhcpd.conf file as-- :
ddns-update-style interim;
ignore client-updates;
subnet 192.168.70.0 netmask 255.255.255.0 {
option routers 192.168.70.1;
option subnet-mask 255.255.0.0;
option nis-domain "dypcoe.com";
option domain-name "dypcoe.com";
option time-offset -18000; # Eastern Standard Time
range dynamic-bootp 192.168.70.128 192.168.70.254;
default-lease-time 21600;
max-lease-time 43200;
}
#
ignore client-updates;
subnet 192.168.70.0 netmask 255.255.255.0 {
option routers 192.168.70.1;

option nis-domain "dypcoe.com";
option domain-name "dypcoe.com";
option time-offset -18000; # Eastern Standard Time

default-lease-time 21600;
max-lease-time 43200;
}
#

Is your address rang 192.168.70.x or 192.168.0.x? your reverse zone is setup as 192.168.0.x I bet 'host 192.168.0.1' will work. basically you have the reverse setup incorrectly.0
