DNS Issue

Hello

I got an issue with rndc. I've read a lot about it en there are many people with the same problem but i can't solve it. I generated a new key but that wasn't the solution. The key i use is the same in named.conf;rndc.conf and rndc.key

on my first dns i use ubuntu 5.1o en my second dns ubuntu 6.0.6.

The error i got is.

rndc: connection to remote host closed
This may indicate that the remote server is using an older version of
the command protocol, this host is not authorized to connect,
or the key is invalid.

When i check the version with: rndc -V the first dns tells me that i'm using Version: 9.3.1 and the second dns is using Version: 9.3.2

Could this be the problem and if it is how can i solved the problem?

 

What's in the logs? What's in your named.conf?

 

named.conf

# cat /etc/bind/named.conf

key "rndc-key" {
algorithm hmac-md5;
secret "5Zmlv/bRToWX6Ilr0lXjbw==";
};

controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};

# cat /etc/bind/rndc.conf
key "rndc-key" {
algorithm hmac-md5;
secret "5Zmlv/bRToWX6Ilr0lXjbw==";
};

options {
default-key "rndc-key";
default-server 127.0.0.1;
default-port 953;

# cat /etc/bind/rndc.key
key "rndc-key" {
algorithm hmac-md5;
secret "5Zmlv/bRToWX6Ilr0lXjbw==";
};


And in my sylog:

Sep 15 22:12:41 ns1 named[7935]: invalid command from 127.0.0.1#53907: bad auth

I'll hope you can help me.

 

Did you kill all previous BIND processes before you tried to start it?

 

Thanks Falko

I didn't know the solution was so easy. Thanks

 

what was the solution? can you help me please. I have this in my syslog:
11:19:16 server1 named[5676]: binding TCP socket: address in use
Nov 3 11:19:16 server1 named[5676]: listening on IPv4 interface eth0, 192.168.1.3#53
Nov 3 11:19:16 server1 named[5676]: binding TCP socket: address in use
Nov 3 11:19:16 server1 named[5676]: couldn't add command channel 127.0.0.1#953: address in use
Nov 3 11:19:16 server1 named[5676]: couldn't add command channel ::1#953: address in use
I have Ubuntu 6.10 server fresh install

 

What's the output of

Code:

netstat -tap

? Do you get any error messages when you restart BIND?

 

This also helped me after an upgrade from Etch to Lenny, thanks!
