I am able to connect to both wired and wireless networks and able to browse via a browser. So I don't think there's any network issue.



However I cannot run any internet based command from my terminal
even a sudo apt-get update
command gets stuck showing



`0% [Connecting to 7.1.1.12 (7.1.1.12)] [Connecting to 7.1.1.12 (7.1.1.12)]`


and get stuck there.



I tried doing sudo iptables -F after following another answer but to no good.



Please help me with this.

    Are you sure it is supposed to be connecting to US Department of Defence? They don't seem to have any web server on that address, so I am suspecting it isn't legit. Somebody may have been forging some DNS replies.

In your case, the apt-get command is finding those http_proxy entries and attempting to connect to the internet through them. In this case, it is an IP address belonging to the Department of Defense, and the :3128 is indicating Squid.



Either you do work for the DoD - in which case you should not be posting this information on a public forum, this should be going through your department admin.



Or you accidentally added those entries there. Check your /etc/environment file for those entries and comment them out. If it isn't in /etc/environment, have a look at your ~/.profile file as well; same deal, just comment them out.

    Ok, i see a space into the URL, just before the IP addresses. Please remove those spaces from those *proxy env variables, and if that doesn't work, please try to unset it.



    To set it correctly:
    export http_proxy=http://7.1.1.12:3128/



    To unset it:
    unset http_proxy



    Edit: Just repeat it for all *proxy variables

                  Ok, i see a space into the URL, just before the IP addresses. Please remove those spaces from those *proxy env variables, and if that doesn't work, please try to unset it.



                  To set it correctly:
                  export http_proxy=http://7.1.1.12:3128/



                  To unset it:
                  unset http_proxy



                  Edit: Just repeat it for all *proxy variables
