Hi,
          It's just past 3am and for the past 6 hours I've been 
configuring a secondary name server to replace one that just crashed.  
My problem appears to be that port 53 is not open for some reason on my 
server even though I have this:

[root at tribe etc]# netstat -an | grep ":53 "
tcp        0      0 205.211.154.3:53            
0.0.0.0:*                   LISTEN
tcp        0      0 127.0.0.1:53                
0.0.0.0:*                   LISTEN
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*

udp        0      0 127.0.0.1:53                0.0.0.0:*
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*

But with a test from
http://www.yougetsignal.com/tools/open-ports/
it says port 53 is closed.

I'm using CentOS 6.0 and BIND 9.7.3-P3-RedHat-9.7.3-8.P3.el6_2.2

I'm not using iptables (well I didn't configure any)

[root at tribe log]# iptables --line-numbers -n -L
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination
1    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state

4    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state

5    REJECT     all  --  0.0.0.0/0            0.0.0.0/0

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination
1    REJECT     all  --  0.0.0.0/0            0.0.0.0/0           
reject-with icmp-host-prohibited

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination

Currently this server is not behind any type of firewall.

Can someone suggest something I have forgotten?

TIA,
Shane
