Many of us on a college campus or office network access the Internet through a proxy server. How do you set the proxy server details in your shell environment? You can set the proxy for different protocols as follows:

export htlp..J)roxy="htlp://1921680 1:3128"; // HTTP proxy export ftp..J)roxy="192.168.0.1:3128"; //FTPproxy

If you want these settings to be permanent, each time you log in add these lines to your /.bash-profile file. That's all, folks! Hope you have enjoyed learning the secrets of networking. Happy hacking till we meet again!
