Configure the server

in named.conf add the key and setup the transfer
key “name-ofzone.com” {
algorithm hmac-md5;
secret “eoifl2349304rrjabwqA==”;
};
server 10.44.21.20 { keys { “name-ofzone.com”; }; };

‘’so far I’ve found that the keys also need to be the same. If there not security: error: client 10.44.21.24#1341: request has invalid signature: TSIG name-ofzone-com: tsig verify failure (BADKEY) is seen in the logs

Configure the zone

zone “name.ofzone.com” { type slave; file “/zones/slave/name.ofzone.com.db”; masters { 10.44.21.20; }; };
