How to change the DNS name server? [duplicate]
I suspect that the name server provided by my ADSL modem/router is buggy. Whenever I browse to a website for the first time in ubuntu, resolving the domain name takes at least 15 seconds.
To work around that problem, I changed the nameserver configuration in /etc/resolv.conf from 192.168.1.1 (my ADSL modem) to 8.8.8.8 (google's primary DNS). This seems to fix the problem, but unfortunately my changes to /etc/resolv.conf are overwritten by "NetworkManager" at each startup.
What is the proper way to configure the name server IP in ubuntu 10.4?
Solution 1:
If you have typical connection setup with the network manager and DHCP, try the following:
- Right click on the network manager icon in the panel and choose "Edit connections..."
- Select your connection from the wired or wireless tab, choose "Edit"
- (Enter your password if the connection is set as "system-wide available")
- Choose IPv4 settings tab
- Switch method to "Automatic (DHCP) addresses only"
- Enter the name server you want in the box "Additional DNS servers" and press "Apply"
That should do the trick.
Solution 2:
The best way to set a nameserver via the CLI, without NetworkManger, with a static address, or independent of the connection is this:
Install the resolvconf package.
Run
sudo nano /etc/resolvconf/resolv.conf.d/head
(ignore the scary warning. /etc/resolv.conf is autogenerated, so the warning is there so it will get put in /etc/resolv.conf when /etc/resolv.conf is generated.) To the end of the file, add
nameserver <ip_of_nameserver>
Press Ctrl x and answer yes to saving the file. To finish up, regenerate /etc/resolv.conf so the changes are applied right now:
sudo resolvconf -u
