BIND 9 的 nsupdate dyndns 更新给出:“tsig 验证失败(BADKEY)”

Lit*_*tch 9 domain-name-system linux bind dyndns named-conf

我已经在 DDNS 上浏览了这么多 HOWTO 页面来尝试解决这个问题......我不知所措。

WorkstationX = CentOS 6.2 x64 ServerX = Ubuntu 12.04 LTS x64

我不明白为什么它不起作用......我真的没有想法。我已经多次重新生成和重新配置所有内容。

我已经确定:

其中一些有不同的生成密钥的方法,但其余的都是相同的......而且,当我尝试 nsupdate 时 - 即使在运行 dnssec-keygen 的服务器上(以及 bind 所在的位置),我也得到相同的日志条目:

从这个nsupdate:

nsupdate -k Kdomain2.com.au.+157+35454.key
server localhost
zone domain2.com.au.
update add test.domain2.com.au. 86400 IN A 10.20.30.40

我收集的是正确的生成方法:

dnssec-keygen -a HMAC-MD5 -b 512 -n HOST domain2.com.au.

nsupdate有一些怪癖,并在使用 调用时假定一些命名约定-k。从手册页来看,我认为您的密钥名称可能以某种方式被称为domain2.com.au.

你能尝试以下方法吗?

nsupdate -y \
  'rndc-key:vZwCYBx4OAOsBrbdlooUfBaQx+kwEi2eLDXdr+JMs4ykrwXKQTtDSg/jp7eHnw39IehVLMtuVECTqfOwhXBm0A=='
