Linux Mint - hardcode DNS

Jagera

recent convert to Linux here.

I have a USB dongle for internet, and sometimes I have connectivity, sometimes not.

The "sometimes not" scenarios seem to be lacking a DNS primary & secondary server. Thus, I am technically connected to my providor, it says "connected" but I have no internet connectivity.

Is there a way I can hardcode the Wireless Broadband connection to a particular DNS, even OpenDNS would do.

Thanks

There's probably a nice UI to do it but you can do it just as quickly from the console:

sudo vim /etc/resolv.conf

Enter the DNS servers, each on a new line. Save. I've specified vim as the editor there but use whatever's best for you, like nano or pico.

Here's what mine looks like (for opendns):


# Generated by dhcpcd for interface eth0
nameserver 208.67.222.222
nameserver 208.67.220.220

OK a few issues I had after trying the above

I was not able to edit the resolv.config file from my user account. Insufficient privilages. I thought I had given the user all of the rights, guess not.

So I logged in as root, and edited the file from there. However after rebooting, the file reverted back to its original, which was simply #Generated by NetworkManager, with nothing else.

I am able to connect no probs from windoze, so its definitely some configuration problem.

I can send attach screenshots of the Wireless Broadband setting if it may help.

I am also questioning my user privilages, and wondering if this has something to do with it

I just remembered that this was going to happen to you, then I see that it has.

So firstly, on the permissions thing. You'll find that your user account can't edit *any* files that are in /etc and that's a good thing. If you want to edit them, switch to root (or use sudo), make a backup, then fire ahead.

To change to using openDns try this link. It's for ubuntu but will be fine for mint.
