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/";
