DNS Update error using TSIG.

Posted May 2, 2014 8.7k views
Hello, I'm trying to use nsupdate with TSIG but I'm getting the following error: output: ; TSIG error with server: tsig indicates error output: update failed: NOTAUTH(BADKEY) I have reviewed all the setup, but I didn't managed to found anything wrong. The key was generated and inserted into the named.conf file as show below: include "/etc/bind/ddns.atcbsb.net.br"; zone "ddns.atcbsb.net.br" in { type master; file "/etc/bind/ddns.actsbs"; allow-query { any; }; allow-transfer { node; }; allow-update { key "atcbsb.net.br."; }; }; My key is the shown below: key "atcbsb.net.br." { algorithm hmac-md5; secret "XXXXXXXXXXXXX"; }; I checked the key in both *.key and *.private files and they are the same. Any help will be appreciated. Marcio

A strong bit of advice: remove the secret part so we don't see it. That's just base64 encoded.
