Do you connect to the internet via a proxy server?

What is the output of the terminal commands
echo $http_proxy
grep proxy /etc/environment
grep proxy /etc/bash.bashrc
grep proxy ~/.bashrc

Hi,

Here is the output

root@ubuntu-2:~# echo $http_proxy
http://proxy-server.com:8080/
root@sdn-ubuntu-2:~# grep proxy /etc/environment
http_proxy="http://proxy-server.com:8080/"

Is that entry
http_proxy="http://proxy-server.com:8080/"
in the file /etc/environment on purpose? I do not think that it makes sense.

Open a terminal and try

unset http_proxy
ping -c 3 8.8.8.8

Does it now work?
I am quite sure that you should remove that proxy entry from /etc/environment.

Can you help with this problem?
