<p style="margin-top: 0px; margin-right: 0px; margin-bottom: 5px; margin-left: 0px;">rndc（remote name domain controller）是BIND安装包提供的一种控制域名服务运行的工具，它可以运行在其他计算机上，通过网络与DNS服务器进行连接，然后根据管理员的指令对named进程进行远程控制，此时，管理员不需要DNS服务器的根用户权限。使用rndc可以在不停止DNS服务器工作的情况进行数据的更新，使修改后的配置文件生效。在实际情况下，DNS服务器是非常繁忙的，任何短时间的停顿都会给用户的使用带来影响。因此，使用rndc工具可以使DNS服务器更好地为用户提供服务。</p>
<p style="margin-top: 5px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;">rndc与DNS服务器实行连接时，需要通过数字证书进行认证，而不是传统的用户名/密码方式。在当前版本下，rndc和named都只支持HMAC-MD5认证算法，在通信两端使用共享密钥。rndc在连接通道中发送命令时，必须使用经过服务器认可的密钥加密。为了生成双方都认可的密钥，可以使用rndc-confgen命令产生密钥和相应的配置，再把这些配置分别放入named.conf和rndc的配置文件rndc.conf中</p>
