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?
