linux - BIND9、nsupdate 和该死的 DDNS

Question

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并重新配置了所有内容。

我已经确定：

其中一些具有不同的生成密钥的方式，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），我也会得到相同的日志条目：

Aug 14 11:20:38 vps named[31247]: 14-Aug-2013 11:20:38.032 security: error: client 127.0.0.1#29403: view public: request has invalid signature: TSIG domain2.com.au.: tsig verify failure (BADKEY)

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
show
send

我收集的是正确的生成方法：

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

named.conf （IP 已更改为隐私）：

acl ipv4                { 0.0.0.0/0; };
acl ipv6                { 2000::/3; ::1; fe80::/10; fec0::/10; };

解决方案：

我不知道为什么，但它现在正在工作。我做的唯一事情是：

# chown -R named:named /var/named 

# find . -type d -exec chmod 770 {} \; 

# find . -type f -exec chmod 660 {} \;
