Default secondary DNS tranfer problem

I have two servers A & B, both with Debian and ISP3 single server setup on each. Each has it's own public ip with it's own DNS running.

I have config on serverA a secondary dns for serverB and config on serverB a secondary dns for serverA. After reboot both servers , resync on dns tools and wait for a few hours. There is still no serverB dns info when do a nslookup on serverA. Anyone have any idea? thanks

Ensue that the "slave" subdirectory in the BIND configuration file directory is writable for bind. You find the detauled bind errors for your problem in the syslog.

have mod changed /etc/bind/slave to 777. Rebooted, still no 2nd dns zone data transfer.

check syslog with error : " transfer of "tadj.com/in" from 123.243.65.181#53:failed to connect :connection refused"

But if i do a nslookup, the tadj dns connection seem ok. ??
root@tadjlinux:/home/terry# nslookup
> server 123.243.65.181
Default server: 123.243.65.181
Address: 123.243.65.181#53
> tadj.com
Server: 123.243.65.181
Address: 123.243.65.181#53

Name: tadj.com
Address: 123.243.65.181
> set type=mx
> tadj.com
Server: 123.243.65.181
Address: 123.243.65.181#53

tadj.com mail exchanger = 10 mail.tadj.com.

is there some thing need to set on the tadj server for connection? Thanks

Make sure that your firewall allows connections to port 53 TCP and UDP.
