The Internet is a melting pot. Both good people and bad people can connect to the Internet like us. The bad guys who make virus infection into people's computers and the good ones who are seeking to protect people are all connected to the same network.

As people have said, the Internet is the best thing in the past. It contains valuable information and resources that anyone can obtain, and most of them can be obtained for free. Some of the most famous universities offer free high-quality courses for anyone who wants to learn. Today, we can all connect to the Internet.

But you must remember that when you connect to the Internet, your computer becomes the target of an attack. Become the target of viruses, Trojans, and other programs.

For this reason, it is recommended that anti-virus and anti-spyware be used to protect computers connected to the Internet. In some cases, even using these software cannot completely guarantee your security. It is always a good idea to add another security layer.

When you are looking for an additional security layer to protect your machine, using the OpenDNS Security DNS framework may be helpful. The Internet is composed of many parts. The best way to ensure security is to protect each part.

First, install anti-virus and anti-spyware on your computer. Because your computer is allowed to query remote DNS servers when browsing the Internet, using protected and secure DNS servers is a good way to protect your computer. In our opinion, using anti-virus and anti-spyware on Ubuntu is not necessary, but it is necessary to use OpenDNS to intercept access to malicious websites. In addition, foreign DNS may be slow, and similar services may appear in China in a period of time .)

This is a concise manual that tells you how to configure the OpenDNS framework on Ubuntu to protect your computer.

sudo gedit /etc/dhcp/dhclient.conf

Finally, add the following line to the open file and save it.

supersede domain-name-servers 208.67.222.222,208.67.220.220;

Restart your computer and have a good time!

Enjoy it!
