linux查看dns命令

  linux下我們要查看服務(wù)器的DNS信息可以通過命令來實(shí)現(xiàn),下面由學(xué)習(xí)啦小編為大家整理了linux查看dns命令的相關(guān)知識(shí),希望對(duì)大家有幫助!

  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命令來查看DNS信息

  root@localhost ~]# dig

  linux查看dns命令4:其它一些方法查看DNS信息

  在網(wǎng)上看到還有一些其他方法,查看服務(wù)器的DNS配置信息,如下所示,不過這些方法,由于環(huán)境限制,我沒有驗(yàn)證過,僅供參考。

  nm-tool | grep DNS

  nmcli dev list iface eth0 | grep IP4
