Changing your Deault DNS provided by the ISP to OpenDNS makes the Web experience more secure and more customized. You can block several sites having viruses, spywares, pornography etc. in a simpler way. Also you can make shotcuts for adreesses that are easy to use with. For example, you only need to type mail to go to mail.yahoo.com if you set the shortcuts properly using OpenDNS. This service is free of cost, and its much faster.
To use OpenDNS you need to register an account at OpenDNS. If you’re using broadband internet such as BSNL, you need to setup the Primary and Secondary DNS to OpenDNS. To do this, follow
- Type/Click 192.168.1.1 in your browser to go to your DSL Router / Modem
- Enter Username and Password (May be both are admin)
- Select DNS and use custom instead of Default DNS. Enter the Primary and secondary DNS as 208.67.222.222 and 208.67.220.220
- Save and reboot the DSL Router.
You can change the settings at OpenDNS Dashbord. Use your security level and shortcuts.
You also need a client side program called ddclient for active communication with OpenDNS (To report your dynamic IP addresses to OpenDNS). It can be downloaded at http://ddclient.wiki.sourceforge.net/. Windows and Mac versions are available at OpenDNS site. For Ubuntu it is availabe via Synaptic.
sudo apt-get install ddclient
The configuration file for OpenDNS is like (in /etc/ddclient/ddclient.conf)
