How to set proxy in Ubuntu using Command Line Interface(CLI)?

Servers such as Ubuntu Server, Fedora Server, VM based servers etc. run without GUI. If the edge of the network requires proxy connection to establish Internet, it has to be done from the CLI. Here are the basic commands to set proxy for Ubuntu.

1. To Check whether proxy is already set:

$echo $http_proxy   (For http proxy)
$echo $https_proxy  (For https proxy)
$echo $ftp_proxy    (For ftp proxy)

2. To set proxy:

$export http_proxy="http://proxyuser:proxypwd@proxy.server.com:port_number/"
$export https_proxy="https://proxyuser:proxypwd@proxy.server.com:port_number/"
$export ftp_proxy="ftp://proxyuser:proxypwd@proxy.server.com:port_number/"

    change proxyuser to your proxy user
    change proxypwd to your proxy password
    change proxy.server.com to the URL of your proxy server
    change port_number to the proxy port configured on your proxy server


Note:

Ubuntu command apt-get does not work after the above setting also. For this, the following steps have to follow:

1. Create a file name 40proxy inside /etc/apt/apt.conf.d/
2. write the following lines(according to the requirement) :

Acquire::http::proxy "http://proxyuser:proxypwd@proxy.server.com:port_number/";
Acquire::https::proxy "https://proxyuser:proxypwd@proxy.server.com:port_number/";
Acquire::ftp::proxy "ftp://proxyuser:proxypwd@proxy.server.com:port_number/";

Set Proxy in Git Application

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Any Git user can upload projects source code to the Git server and share with others. It also allows users to update and synchronous from the local machine. Generally, Git comes with Command Line Interface(CLI) exceptionally few 3rd party GUI applications. 

Git does not use normal system proxy and to connect, proxy has to be explicitly set for this application. If you are trying to connect Github from behind the proxy server, it will not work unless the proxy is set.

How to set proxy from the CLI? Here are the few steps :

1.Check whether proxy is set  :

git config --global --get http.proxy
git config --global --get https.proxy

2. Set proxy :

git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080
git config --global https.proxy https://proxyuser:proxypwd@proxy.server.com:8080

    change proxyuser to your proxy user
    change proxypwd to your proxy password
    change proxy.server.com to the URL of your proxy server
    change 8080 to the proxy port configured on your proxy server

3. To reset this proxy and work without (no proxy):

git config --global --unset http.proxy
git config --global --unset https.proxy
