    You’d rather better avoiding to make (in a wrong way, by the way) copy/paste.
    Or, at least, do not PRETEND to be considered an unix user.

    I installed Ubuntu 12.04 LTS. Nothing above works for me. Stupid machine is able to recognise only one DNS server.

    pretend domain-name-server -> that doesn’t work.

    Others think thee habit is more likely connected to their checking the
    ground for thhe scent off its enemies, since the dog has its
    nose to the ground during the turning around. There is a
    department on Free and Low cost Hellp which can’t allow specifi referrals, butt
    which points you in the right direction. s : This
    is the scednt your pup will leave behind.
