nano /etc/apt/apt.conf

2. Insert lines like this

Acquire::http::proxy “http://proxyserver:port/”;
Acquire::ftp::proxy “ftp://proxyserver:port/”;

WordPress Proxy Setting

When you install wordpress on you web hosting server that located behind proxy such as squid, some features may be disabled. those features like plugin installation and themes selection from internet will be disabled. You may receive message like this.

An Unexpected HTTP Error occurred during the API request.

inside your plugin page or

An Unexpected HTTP Error occurred during the API request.

on a wordpress error, blankpage

you will also receive this error message when you are trying to access theme installation page. if in ordinary hosting we find no problem, than in wordpress behind firewall it becomes a little problem, it make work little bit harder when we want to choose, install, and activate new themes or plugin that supported by wordpress.

we can solve this wordpress proxy setting by adding these lines in wp-config.php

define(‘WP_PROXY_HOST’, ‘192.168.84.101’);
define(‘WP_PROXY_PORT’, ‘8080’);
define(‘WP_PROXY_USERNAME’, ‘my_user_name’);
define(‘WP_PROXY_PASSWORD’, ‘my_password’);
define(‘WP_PROXY_BYPASS_HOSTS’, ‘localhost, www.example.com’);

but you have to make sure you knowproxy configuration in your work place or your hosting server. change the value inside wordpress proxy setting like this according to your own setting.

here is the example
define(‘WP_PROXY_HOST’, ‘cache.caleudum.com’);
define(‘WP_PROXY_PORT’, ‘8080’);
define(‘WP_PROXY_USERNAME’, ‘caleudum’);
define(‘WP_PROXY_PASSWORD’, ‘mypassword’);
define(‘WP_PROXY_BYPASS_HOSTS’, ‘localhost, www.example.com’);

Step by Step to Check Your Internet Connection

After u make sure u have turned on your network interface such as wifi or plugged in your LAN cables, there is some steps u could do to determine whether you get internet access or not:

1. ping localhost, if it doesnt work, then maybe your (pc/laptop) network service is disabled. on windows u can enable it in start > control panel > netwrok connection

2. on windows, chech for logo internet connection, if this icon is clear, it means u are connected to internet. if not, maybe you’re just connected to Local Area Network.

3. on windows use ipconfig command. run > cmd > ipconfig , to see your ip adress. if you see 169.xxx.xxx.xxx as your internet address, it’s default address of microsoft interface, it means your computer didnt get dhcp address. probably thera to many users using internet connection near you. on linux use ifconfig command

4. if you know your gateway address, try to ping it.

5. ping internet familiar (unblocked) address such as google or its (easy to remember) dns address 8.8.8.8 , if this works then u can make sure now u can access internet.
