If bind or dns is specified in the hosts record , use nslookup to ensure that the host name resolves through DNS .

如果在hosts记录中指定bind或dns，那么使用nslookup确认可以通过DNS解析主机名。

If the host name in / etc / hosts doesn 't match the host name returned by nslookup , correct the value in / etc / hosts .

In such a situation , it could be that their DNS information isn 't updated and old addresses are being used , which you can use nslookup to verify quickly .

If you specify bind or dns , then DNS is used to resolve host names , and you can use nslookup to check whether the host name resolves ( see Listing 12 ) .

如果指定bind或dns，那么使用DNS解析主机名，可以使用nslookup检查是否可以解析主机名（见清单12）。

After successfully testing the Internet connection and verifying that DNS is set up correctly by using the ping , traceroute , and nslookup commands , you 're ready to get on the Web .

A common reason for failing the protocol check is inadequate Domain Name System ( DNS ) settings , so try to modify the / etc / hosts file if there is no DNS in your environment , then run the nslookup command to verify the communication .

协议检查失败的一个常见原因是域名系统（DNS）设置适当，所以如果您的环境中没有DNS，那么可以尝试修改/etc/hosts文件，然后运行nslookup命令来验证通信。
