    openvpn connectivity problems.

    Hi all,
    I am trying to connect via VPN to google.com using a NordVPN server but no luck.
    In chrome it says:
    This site canít be reached
    www.google.com server IP address could not be found
    Try checking proxy, firewall, DNS configuration
    DNS_PROBE_FINISHED_BAD_CONFIG

    Not sure where to go from here because I have little knowledge of how the DNS settings work.

    These are the directions I used to set up the openvpn daemon and the NordVPN server.
    https://nordvpn.com/tutorials/linux/openvpn/

    Would like to learn more about networking on linux, if you have any resources that would help me accomplish that please link even if you don't have a solution for my issue.
    Thanks.

    Re: openvpn connectivity problems.

    Where in the tutorial do you get the error? Generally, if you are given credentials, such as they give you, something like
    sudo openvpn ./<configurationfile> will prompt for password (possibly user name too) and once you enter them, it will work. It generally requires sudo privilege as it creates a virtual interface.

    Re: openvpn connectivity problems.

    I do not receive any errors during the tutorial. The only error I receive is when I try connecting to a website on Chrome. I did the tutorial after using
    Code:
    su
    after entering "su" it prompts me for a password which I enter and it gives me root access. After gaining root access I proceeded with the tutorial steps (not needing sudo in each command anymore.)

    After entering
    Code:
    openvpn <configuration file>
    I do input my credentials and it goes through some processes on the terminal which I do not understand yet but last time I encountered the problem it set something like "AUTHENTICATED" I believe.

    FYI: After rebooting it automatically establishes a normal wifi connection (like the one I am using right now)

    Re: openvpn connectivity problems.

    If it says authenticated, that sounds as if it's connecting. After that, can you try running

    ip add sh

    in another terminal? See if it shows the VPN interface.

    Re: openvpn connectivity problems.

    What does that command do (I like to know what commands do before I input them)? I couldn't find it in this quick guide https://access.redhat.com/sites/defa..._jcs_print.pdf

    Re: openvpn connectivity problems.

    You're right, I should have explained that and it's a good question on your part. The ip command is used instead of ifconfig, these days. Often, one can abbreviate the options.

    In this case it's ip (the command) sh (for show) ad (for address, or maybe addresses).

    This will do what the old ifconfig command did, show your interfaces and their addresses if they have any. I have a somewhat old page which gives some of the common ip commands at http://srobb.net/ip.html

    Re: openvpn connectivity problems.

    I found a tcp server that connected and shows at the bottom of the terminal:
    Code:
     Wed Feb 14 14:41:14 2018 Initialization Sequence Complete
    Then I “ip address show” in a different terminal.
    I can confirm that there is a new interface named “tun0”.
    But on the second line it shows
    Code:
    link/none
    if that means anything.
    Thanks.

    Hrrm. Well, tun0 is what you'd expect to see, but it should show an address. It seems like you're doing it right, perhaps they have a support channel, since this appears to be something you've bought.

    Sorry I couldn't be of more help. In my experience (both work and helping friends) it's usually been as straightforward as their docs make it seem.
