Ubuntu configuration steps using OpenDNS

Protecting computer security is something everyone must master. Once the computer is hacked, the computer is small, and the privacy data is leaked. OpenDNS can protect your computer. The following small series will introduce you. The way Ubuntu uses and configures OpenDNS.

Like the saying goes, the Internet is one of the best stuff in the past emerged. It contains valuable information and resources that anyone can access, and most of them are freely available. Some of the most prestigious colleges offer free, high-quality courses for anyone who wants to learn. Today, it is a good thing that we can all connect to the Internet.

But there are some things you must remember. When you connect to the Internet, your computer becomes the target of the attack. Become a target for viruses, Trojans and other programs.

Because of this, computers connected to the Internet are recommended to be protected by anti-virus and anti-spyware software. In some cases, even if you use these software, you can't completely guarantee your safety. Adding a security layer is always a good idea.

Using OpenDNS's secure DNS framework may be helpful when looking to add an extra layer of security to protect your machine. The Internet has many components, and trying to protect each part is the best way to ensure security.

First, you need to install anti-virus and anti-spyware on your computer. Since allowing your computer to query remote DNS servers while browsing the Internet, using a protected and secure DNS server will be a good way to protect your computer. (Annotation: We believe that the use of anti-virus and anti-spyware on Ubuntu is not necessary, but it is necessary to use OpenDNS to intercept access to malicious URLs. In addition, using foreign DNS may be slower, maybe For some time, similar services will appear in China.)

This is a concise manual that shows 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;

The above is how Ubuntu uses and configures OpenDNS. By configuring the OpenDNS framework to block malicious websites, protection is achieved. The purpose of computer security.
