How to set DNS to 8.8.8.8 in Linux?

How to configure DNS in Linux step by step?

I'm trying to learn how to configure DNS in Linux Ubuntu 16.

04 LTS I already had done a lot of research on Google, but I could not figure it out! So, I decided to use StackOverflow community as a reference because of the number of times it is asked questions here. There are many tutorials of how to set up DNS or how to configure my /etc/hosts, but no one answered my questions. I want to use bind. When I use Google or StackOverflow there are many results from the year of 2026 but not so many for today.

How do you configure the DNS with the configuration given below? I have a problem when restarting the network. After restart, when I try to type a website's URL, it cannot find it.

Is the configuration I give above normal and appropriate? I want the website to use the IP of my NAS. You did not really set up dns at all. A good tutorial would be The configuration you set up is more like a caching server. It will store a copy of your current DNS records in a cache that should resolve your names faster. That does not mean you don't have real DNS server on your system, just a caching one that you can also use for other configuration needs (and a lot of people do so).

If you really set up DNS and have your own domain at home.net then yes, that is wrong. You should setup an additional entry in the hosts file in your windows box something like *net 127.1, localhost home.net with your own domain name in it. Do the same on your linux box if you want both the machines to share one DNS record.

How to check DNS server configured in Linux?

How can I check if DNS server is working or not?

There's no need to have a server listening on port 53. Just do dig foo.com Or maybe. Dig @localhost foo.com The first one will get it from the local cache of your machine's DNS server and the second from your DNS server (which must be up and running). For Ubuntu 12.04 Install dnsmasq. Sudo apt-get install dnsmasq. Restart dnsmasq. Sudo service dnsmasq restart. Inspect list of all running dnsmasq instances. Sudo netstat -tulpn 0. If dnsmasq was started by systemd. Find its service name, for example in /lib/systemd/system/networking.service For example for systemd version 219. # systemctl --version. Systemd 219. Find the service name (which might be networking.dhcp):' /lib/systemd/system/networking.dhcp):' /lib/systemd/system/networking.service
(NetworkManagerservice even if this doesn't start the service for some reason. Grep LISTEN 0 Check that there's no process listening on 0.

How to configure the DNS server?

So, I have a small network that only has a NAS (with DDNS) and a wireless router (with DDNS). The NAS is connected to the wifi router by ethernet cable. Is it possible to configure both devices to use Google DNS, such that my phone, notebook and other devices can reach it?

I am not a expert with networking, but when I try to ping my own IP address, it gives me Network is unreachable, which means that it is forwarding the requests to the correct IP, but the routing part is still messed up? Where is the error in this setup? How can I fix it? Update: I am trying to use DNS instead of DHCP. So far I have installed Google DNS on my Router and set up the configuration as follows: It says, my device is successfully using 8.8 and 8.4 DNS servers. I am trying to use Google DNS servers for the public DNS name of google.com, but it's not working. Is there anything wrong with my config files?

Note: This is not for an actual production environment, this is just for my own test and evaluation purposes. Your problem is likely that your router is not properly configured. The DNS servers on your router must be allowed by the router to be used. AFAIK, most home routers do not allow external addresses. Your router is likely giving an error because it's not configured to do this, but is redirecting traffic destined for 8.4 to 8.4
Set up your router so that it allows 8.4 Enable DHCP snooping for 8.4 On your router, add 8.4 to the DNS Forwarders list.

That should work, but if you have other computers on your network, I would recommend adding them to your router's firewall to prevent them from accessing the outside world.

How to set DNS to 8.8.8.8 in Linux?

I am running RedHat 6 and my server does not work with 8.

8 DNS, it works fine with 4.2 DNS. I have tried many ways to change the DNS server settings but I cannot find a way to change the DNS server on Redhat 6.

In /etc/sysconfig/network-scripts/ there is an option named "DNS". This is a file which has some entries for the DNS and DHCP settings. I am not sure which entry has to be changed. But it would be very much appreciated if someone can help me with this.

You'll also want to make sure that your network card doesn't automatically set the DNS server back to the local machine. That's what's causing my DNS problems.

I don't know much about Linux networking but if you've got a DNS issue, you probably have a problem with the DHCP server - have you confirmed that? BartekNov 17 '12 at 5:43. 2 Answers.
It is not an easy question. You need to disable name resolution on all the services. There are several ways to do this.

The first one is to disable all the name resolution services in /etc/nsswitch. After you change the hosts line, you should restart the service using. /etc/init.d/sshd restart or
