1:查看/etc/resolv.con文件 [root@localhost ~]# cat /etc/resolv.conf nameserver 192.168.xxx.xxx # search localdomain [root@localhost ~]# 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 ~]# 3:使用dig命令来查看DNS...
在网络中,推荐使用像DNS服务器一样分层的时间服务器来同步时间。 同步时间,可以使用ntpdate命令,也可以使用ntpd服务(debian中ntp服务器为ntp服务,需要安装apt-get install ntp,同时对上手动同步时间需要用到ntpdate,故还需安装apt-get install ntpdate)。 使用ntpdate比较简单。格式如下: [root@linux ~]# ntpdate...
There are two main problems with the traditional DNS configuration. First, the local machine does not cache name server replies, so frequent repeated network access may be unnecessarily slow due to name server requests. To solve this problem, many machines (and routers, if acting as name server...
Although most systems used to configure the network in their boot mechanisms—and many servers still do— the dynamic nature of modern networks means that most machines don’t have static (unchanging) IP addresses. Rather than storing the IP address and other network information on your machine, ...
In this article, we will show you the different methods of finding the currently used DNS nameservers of the most popular Linux distributions, i.e. Ubuntu, Debian, Linux Mint, Fedora, RHEL, Rocky Linux, etc. Topic of Contents: Method 1: Finding the Currently Used DNS Nameservers by Readin...
What is a DNS cache? The Domain Name System (DNS) is a global naming system designed to map domain names to their corresponding server IP addresses. The user end of the DNS is called a DNS resolver (Stub Resolver) that queries the DNS cache reducing the load on upstream DNS servers. ...
