After reading about DNS64, those of you who have already readDNS and BIND’s “Security” chapter may object: doesn’t the mechanism,when it’s working as designed, break DNSSEC? Yes, it sure can. Imagine that a monolingual IPv6 client queries a recursive name server that supports DNS64...
默认情况下BIND服务器的网络端口是:UDP 53用于常规解析;TCP 53用于数据同步;TCP 953用于IPv6解析。针对Linux下的BIND服务器, 设置系统防火墙规则, 关闭不必要的网络端口。修改防火墙配置文件/etc/sysconfig/iptables, 具体配置如下: (3) 控制BIND运行权限 通过chroot技术控制BIND的权限范围, 使BIND只能在chroot目录中具...
The domain name system is divided into zones (also called domains), each of which has a name like example.com or foo.com.au. Zones are arranged in a hierarchy, which means that the foo.com.au zone is part of the com.au zone, which in turn is part of the au domain. At the very...

IPv6 addresses are looked up using nibble format under the IP6.ARPA domain. -y [hmac:]keyname:secret This option signs queries using TSIG with the given authentication key. keyname is the name of the key, and secret is the base64-encoded shared secret. hmac is the name of the key ...
如果主dns不设置server语句的话,则主服务器主动发送给从dns的notify会被拒绝;如果从服务器不设置server语句的话,则不能实现分view同步的功能;如果主从服务器时间不同步的话,则会导致验证失败;如果从dns的ip匹配到主dns的view,则会导致只同步这个view的数据下来,即使配置了key。

Virtualmin is configured to setup DNS zones, but this system is not setup to use itself as a DNS server. Either add 127.0.0.1 to the [list of DNS servers] (https://sd.fqdn.tld:10000/net/list_dns.cgi), or turn off the BIND feature on the [Features and Plugins] (https://sd.fqdn...
With over 75 machines and only one of me, visiting each workstation to see network settings isn't really an option. The odd thing is when I turn off a laptop that's claiming to have a duplicate IP address, you'd think I could ping the address and get a response from the other ma...
