佳洲分享

  linux下我们要查看服务器的DNS信息可以通过命令来实现,下面由学习啦小编为大家整理了linux查看dns命令的相关知识,希望对大家有帮助!

  linux查看dns命令1:查看/etc/resolv.con文件

  [root@localhost ~]# cat /etc/resolv.conf

  nameserver 192.168.xxx.xxx

  #search localdomain

  [root@localhost ~]#

  linux查看dns命令2:使用nslookup命令查看DNS信息

  [root@localhost ~]# nslookup 127.0.0.1 | grep Server

  Server: 192.168.xxx.xxx

  [root@localhost ~]#

  linux查看dns命令3:使用dig命令来查看DNS信息

  root@localhost ~]# dig

  linux查看dns命令4:其它一些方法查看DNS信息

  在网上看到还有一些其他方法,查看服务器的DNS配置信息,如下所示,不过这些方法,由于环境限制,我没有验证过,仅供参考。

  nm-tool | grep DNS

  nmcli dev list iface eth0 | grep IP4
