Fixing intermittent DNS problems on Ubuntu 12.04

October 7th, 2012 at 3:59 pm

I’ve been having some intermittent DNS resolution failures on my recent installation of Ubuntu 12.04. Googling showed that I’m not the only one, and the solution found here seems to be working for me:

sudo vi /etc/NetworkManager/NetworkManager.conf

Then comment out (by prepending a #) the line dns=dnsmasq. Finally:

sudo restart network-manager

    hi, sorry for this, but am a complete novice at ubuntu/linux, and have no idea what you mean by ‘comment out’ and how to do it… appreciate the help.

    @sunilesh,

    By “comment-out” in this particular file I mean add a hash symbol – ‘#’ in the beginning. So instead of:

    dns=dnsmasq

    You should have:

    #dns=dnsmasq

    Alternatively, you can just delete the whole line.
