我已经在 Centos6.5 中设置了一个 DNS 服务器，它可以与除 ubuntu 之外的所有客户端计算机配合使用，但现在我在使用 ubuntu 时遇到了问题。当我尝试从台式机 ping 到 DNS 服务器时，ping masterdns.arrivu.local 无法 ping 通，它返回的结果为
sysadmin@localhost:~$ ping masterdns.arrivu.local
ping: unknown host masterdns.arrivu.local
但当我用 IP 地址 ping 时，它正常工作
sysadmin@localhost:~$ ping 192.168.1.15 -c 3

rtt min/avg/max/mdev = 0.265/0.386/0.450/0.089 ms
我已经使用主机检查过它返回的 IP
sysadmin@localhost:~$ host masterdns.arrivu.local
masterdns.arrivu.local has address 192.168.1.15
我的问题是我想使用主机名而不是 ip 来 ping 和 ssh，如下所示
ping masterdns.arrivu.local ssh[电子邮件保护]
使用装有 Ubuntu 的台式机进行即时通讯
sysadmin@localhost:~$ lsb_release -a
No LSB modules are available.

我的桌面 IP 是 192.168.1.99
当我从我的桌面进行挖掘时，我得到了 DNS 的回复
