Configuring OpenDNS on your router

July 11th, 2019

Nowadays, web filtering is a must! Whether it’s your home or your office, web filtering can protect you and your machine much more than you can imagine.

OpenDNSOpenDNS is a free DNS service that can be used to prevent access to unsafe or inappropriate websites on your network for free. To start, just click on the following link and create an account of your choice:


Then download the IP updater and install. The IP updating software keeps updating your dynamic IP with OpenDNS. If you are with Windows, it’s a rather straightforward installation but with Linux, the process is a little longer. BTW, if you have any issues with the Linux installation, drop me a line and I will be happy to share my knowledge.

Once you have set up your account, you can login to your router gateway and enter the IP’s provided by OpenDNS which is always and respectively.

If you are with Sri Lanka Telecom and using a fiber-optic line, you would most probably be using the ZTE F660 router. But if you are not, that’s not a problem, since the settings would be somewhat similar on other routers as well.

First, you have to enter the router gateway address on the browser to get back-end access and change the DNS. In this case, it would be but if it’s not, just call your ISP.

Typically, your user credentials would be “user” and then again “user” but if that’s not correct, just phone your ISP and they would be happy to assist.

Click on “details setup” then Application > DNS Service > DNS as shown in the following image:

ZTE F660 router settings for OpenDNS

As mentioned above, the primary and secondary server IP’s provided by OpenDNS are as follows:
Finally, click “Submit”

Now all users bypassing your router would be going through OpenDNS!

There are three levels of protection offered by OpenDNS. You can customize this filtering level by adding additional categories as well.

High: Protects against all adult-related sites, illegal activity, social networking sites, video sharing sites, and general time-wasters (26 categories in this group).
Moderate: Protects against all adult-related sites and illegal activity (13 categories in this group).
Low: Protects against pornography (4 categories in this group).

The “Custom” option lets you add the categories of your choice.

The “None” option skips all forms of filtering and protection, but still, all the traffic would go through the OpenDNS servers.

There is also a way to manage individual domains where you can block specific website URLs. Nice!

How to check the security settings of OpenDNS configuration?

Just click on this demo site: http://www.internetbadguys.com for testing the security setting. If all is well, you will see the following message:
“This site is blocked due to a phishing threat.”

If you don’t get this message, there’s something wrong but fret not! The support team at OpenDNS are really good. If you want to clarify anything, just send them a support ticket and they will answer promptly!

Get a free Windows 10 upgrade even now

Windows 10 upgrade

Windows 7 users would remember Microsoft’s much-hyped free upgrade offer for Windows 10 in 2016. Many thought the offer had ended but it has not! The GWX tool may be gone, but all the other upgrade tools still work. The end result is an apparently valid digital license, and there’s no evidence that the free upgrades will end any time soon.

So if you have a licensed version of Windows 7 and want to upgrade, go for it even now:


‘Vague, but exciting’: 30 years on

March 12th, 2019
Tim Berners-Lee
Tim Berners-Lee: father of the internet

In March 1989, Tim Berners-Lee submitted a proposal for an information management system to his boss, Mike Sendall. On the top margin of the proposal his boss wrote the words – ‘Vague, but exciting’.

Today, the web celebrates 30 years on earth and is far from being vague but truly exciting. Very exciting! Tim Berners-Lee invented the World Wide Web (WWW) on March 12, 1989 at CERN, a research organization near Geneva.

Tim Berners-Lee also made the first web browser known as WorldWideWeb, but it was the Mosaic web browser which made the World Wide Web popular. Its features including the URL bar, back button, forward button and refresh button, still remain featured in modern day web browsers.

The first website can be accessed through the URL “info.cern.ch” which also happens to be the original address. Titled “World Wide Web”, the website has hyperlinks to different documents related to the web. Here, users can find out what is hypertext, a summary of the project, software products and help with the browser.

Three decades on, more than half of the global population is online. It has fundamentally changed commerce, communication, and countless other spheres of life. It’s a good place as well as a bad place. In fact, it can be termed a very bad place. But as Sir Tim Berners-Lee puts it in an interview with TIME, he says “the way the web works is you don’t follow those links. If those links lead you to garbage, don’t go there again.”

Good advise indeed!

Sri Lanka National Day Celebrations

February 4th, 2019

Today, Sri Lanka will celebrate its 71st Independence Day with festivities organized throughout the country. The main event will take place at Galle Face where President Maithripala Sirisena and Prime Minister Ranil Wickremesinghe presides the show. Maldivian President Ibrahim Mohamed Solih will attend the ceremony as Guest of Honour.

Google is also celebrating the Sri Lanka National Day with a doodle that resembles very close to the one portrayed last year. For some reason, the emphasis is on the red and green colours only. I did use the colour picker on the doodle and yes, the colours are from the flag!

Google Doodle Sri Lanka National Day 2019
Google Doodle – February 4th, 2019

So what is a Google doodle? According to Google:
“Doodles are the fun, surprising, and sometimes spontaneous changes that are made to the Google logo to celebrate holidays, anniversaries, and the lives of famous artists, pioneers, and scientists.”

The Google team have created over 2000 doodles on their homepages around the world over the years.

In fact, Google users/the public can submit ideas for doodles. So remember, if you want to be creative, you can email proposals@google.com with ideas for the next Google doodle.

How to download a website using wget Linux command

November 21st, 2018

Website codeThe wget utility is a powerful and effective mode that enables you to download web pages, files and images from the web using the Linux command line.

For this guide, we will learn how to download this free one page template – https://blackrockdigital.github.io/startbootstrap-coming-soon/.

So you open up the terminal on Linux.

It is worth creating your own folder on your machine using the mkdir command and then moving into the folder using the cd command.

For example, let’s make a folder named “onepage”:

mkdir onepage
cd onepage
wget https://blackrockdigital.github.io/startbootstrap-coming-soon/ 

The result is a single index.html file. On its own, this file is useless as the content, images and stylesheets are not included.

To download the full site and all the pages you can use the following command:

wget -r https://blackrockdigital.github.io/startbootstrap-coming-soon/

This downloads the pages recursively up to a maximum of 5 levels deep.

Five levels deep might not be enough to get everything from the site. You can use the -l switch to set the number of levels you wish to go to as follows:

wget -r -l10 https://blackrockdigital.github.io/startbootstrap-coming-soon/

If you want infinite recursion you can use the following:

wget -r -l inf https://blackrockdigital.github.io/startbootstrap-coming-soon/

You can also replace the inf with 0 which means the same thing.

There is still one more problem. You might get all the pages locally but all the links in the pages still point to their original place. It is therefore not possible to click locally between the links on the pages.

You can get around this problem by using the -k switch which converts all the links on the pages to point to their locally downloaded equivalent as follows:

wget -r -k https://blackrockdigital.github.io/startbootstrap-coming-soon/

If you want to get a complete mirror of a website you can simply use the following switch which takes away the necessity for using the -r -k and -l switches.

wget -m https://blackrockdigital.github.io/startbootstrap-coming-soon/

Therefore, if you have your own website you can make a complete backup using this one simple command.

Do remember though, not all websites will grant you permission to download all the pages.  If you are the legitimate owner, you can still get though by using the following switches to specify the username and password.

wget --user=yourusername --password=yourpassword

Beware, on a multi user system if somebody runs the ps command, they will be able to see your username and password.

The wget command has a huge number of options and switches. It is worth reading the manual page for wget by typing the following into your terminal window:

man wget

Microsoft Windows removes warning about installing Chrome, Firefox…

September 18th, 2018

Windows 10 warningThere was much talk earlier this week, of Windows 10’s warning when users tried to install the Chrome, Firefox, Opera or Vivaldi web browsers, “You already have Microsoft Edge — the safer, faster browser for Windows 10.” The dialog box presented two options: “Open Microsoft Edge” — the default — and “Install anyway.”

The good news, according to CNET, is that a new “fast-ring” test version of Windows, Insider Preview Build 17760, no longer interrupts the installation of rival browsers.

Can you remember old Internet Explorer (IE) browser in the first browser wars two decades ago? That was the time when IE dominance got Microsoft in trouble, with the US Justice Department and the European Commission dragging the company through antitrust proceedings.

Today, Edge – the “safer and faster” browser is struggling to reclaim even a shadow of the dominance it once held with its IE browser. According to StatCounter, the worldwide browser market share is dominated by Chrome (60%) while Edge remains at a dismissive 2 percent!
