Change Windows 10 default lock screen image via win registry LockScreenImage key change

Tuesday, September 21st, 2021

fix-lock-screen-missing-change-option-on-windows-10-windows-registry-icon

If you do work for a corporation on a Windows machine that is part of Windows Active Directory domain or a Microsoft 365 environment and your Domain admimistrator after some of the scheduled updates. Has enforced a Windows lock screen image change.
You  might be surprised to have some annoying corporation logo picture shown as a default Lock Screen image on your computer on next reoboot. Perhaps for some people it doesn't matter but for as a person who seriously like customizations, and a valuer of
freedom having an enforced picture logo each time I press CTRL + L (To lock my computer) is really annoying.

The logical question hence was how to reverse my desired image as  a default lock screen to enkoy. Some would enjoy some relaxing picture of a Woods, Cave or whatever Natural place landscape. I personally prefer simplicity so I simply use a simple purely black
background.

To do it you'll have anyways to have some kind of superuser access to the computer. At the company I'm epmloyeed, it is possible to temporary request Administrator access this is done via a software installed on the machine. So once I request it I become
Administratof of machine for 20 minutes. In that time I do used a 'Run as Administartor' command prompt cmd.exe and inside Windows registry do the following Registry change.

The first logical thing to do is to try to manually set the picture via:
 

Settings ->  Lock Screen

But unfortunately as you can see in below screenshot, there was no way to change the LockScreen background image.

Windows-settings-lockscreen-screenshot

In Windows Registry Editor

I had to go to registry path


[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\.]

And from there in create a new "String Value" key
 

"LockScreenImage"


so full registry key path should be equal to:


[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization\LockScreenImage]"

The value to set is:

C:\Users\a768839\Desktop\var-stuff\background\Desired-background-picture.jpg

windows-registry-change-lock-screen-background-picture-from-registry-screenshot

If you want to set a black background picture for LockScreen like me you can download my black background picture from here.

That's all press CTRL + L  key combination and the black screen background lock screen picture will appear !

Hopefully the Domain admin, would not soon enforce some policty to update the registry keys or return your old registry database from backup if something crashs out with something strange to break just set configuration.

To test whether the setting will stay permanent after the next scheduled Windows PC update of policies enforced by the Active Directory (AD) sysadmin, run manually from CMD.EXE

C:\> gpupdate /force


The command will download latest policies from Windows Domain, try to lock the screen once again with Control + L, if the background picture is still there most likely the Picture change would stay for a long.
If you get again the corporation preset domain background instead,  you're out of luck and will have to follow the same steps every, now and then after a domani policy update.

Enjoy your new smooth LockScreen Image 🙂

 

Improve wordpress admin password encryption authentication keys security with WordPress Unique Authentication Keys and Salts

Friday, October 9th, 2020

wordpress-improve-security-logo-linux

Having a wordpress blog or website with an admistrator and access via a Secured SSL channel is common nowadays. However there are plenty of SSL encryption leaks already out there and many of which are either slow to be patched or the hosting companies does not care enough to patch on time the libssl Linux libraries / webserver level. Taking that in consideration many websites hosted on some unmaintained one-time run not-frequently updated Linux servers are still vulneable and it might happen that, if you paid for some shared hosting in the past and someone else besides you hosted the website and forget you even your wordpress installation is still living on one of this SSL vulnerable hosts. In situations like that malicious hackers could break up the SSL security up to some level or even if the SSL is secured use MITM (MAN IN THE MIDDLE) attack to simulate your well secured and trusted SSID Name WIFi network to  redirects the network traffic you use (via an SSL transparent Proxy) to connect to WordPress Administrator Dashbiard via https://your-domain.com/wp-admin. Once your traffic is going through the malicious hax0r even if you haven't used the password to authenticate every time, e.g. you have saved the password in browser and WordPress Admin Panel authentication is achieved via a Cookie the cookies generated and used one time by Woddpress site could be easily stealed one time and later from the vicious 1337 h4x0r and reverse the hash with an interceptor Tool and login to your wordpress …

Therefore to improve the wordpress site security it very important to have configured WordPress Unique Authentication Keys and Salts (known also as the WordPress security keys).

They're used by WordPress installation to have a uniquely generated different key and Salt from the default one to the opened WordPress Blog / Site Admin session every time.

So what are the Authentication Unique Keys and Salts and why they are Used?

Like with almost any other web application, when PHP session is opened to WordPress, the code creates a number of Cookies stored locally on your computer.

Two of the cookies created are called:

 wordpress_[hash]
wordpress_logged_in_[hash]

First  cookie is used only in the admin pages (WordPress dashboard), while the second cookie is used throughout WordPress to determine if you are logged in to WordPress or not. Note: [hash] is a random hashed value typically assigned to your session, therefore in reality the cookies name would be named something like wordpress_ffc02f68bc9926448e9222893b6c29a9.

WordPress session stores your authentication details (i.e. WordPress username and password) in both of the above mentioned cookies.

The authentication details are hashed, hence it is almost impossible for anyone to reverse the hash and guess your password through a cookie should it be stolen. By almost impossible it also means that with today’s computers it is practically unfeasible to do so.

WordPress security keys are made up of four authentication keys and four hashing salts (random generated data) that when used together they add an extra layer to your cookies and passwords. 

The authentication details in these cookies are hashed using the random pattern specified in the WordPress security keys. I will not get into too much details but as you might have heard in Cryptography Salts and Keys are important – an indepth explanation on Salts Cryptography (here). A good reading for those who want to know more on how does the authentication based and salts work is on stackexchange.

How to Set up Salt and Key Authentication on WordPress
 

To be used by WP Salts and Key should be configured under wp-config.php usually they look like so:

wordpress-website-blog-salts-keys-wp-config-screenshot-linux

!!! Note !!!  that generating (manually or generated via a random generator program), the definition strings you have to use a random string value of more than 60 characters to prevent predictability 

The default on any newly installed WordPress Website is to have the 4 definitions with _KEY and the four _SALTs to be unconfigured strings looks something like:

default-WordPress-security-keys-and-salts-entries-in-wordPress-wp-config-php-file

Most people never ever take a look at wp-config.php as only the Web GUI Is used for any maintainance, tasks so there is a great chance that if you never heard specifically by some WordPress Security Expert forum or some Security plugin (such as WP Titan Anti Spam & Security) installed to report the WP KEY / SALT you might have never noticed it in the config.

There are 8 WordPress security keys in current WP Installs, but not all of them have been introduced at the same time.
Historically they were introduced in WP versions in below order:

WordPress 2.6: AUTH_KEY, SECURE_AUTH_KEY, LOGGED_IN_KEY
WordPress 2.7: NONCE_KEY
WordPress 3.0: AUTH_SALT, SECURE_AUTH_SALT, LOGGED_IN_SALT, NONCE_SALT

Setting a custom random generated values is an easy task as there is already online Wordpress Security key Random generator.
You can visit above address and you will get an automatic randomly generated values which could be straight copy / pasted to your wp-config.php.

Howeever if you're a paranoic on the guessability of the random generator algorithm, I would advice you use the generator and change some random values yourself on each of the 8 line, the end result in the configuration should be something similar to:

 

define('AUTH_KEY',         '|w+=W(od$V|^hy$F5w)g6O-:e[WI=NHY/!Ez@grd5=##!;jHle_vFPqz}D5|+87Q');
define('SECURE_AUTH_KEY',  'rGReh.<%QBJ{DP )p=BfYmp6fHmIG~ePeHC[MtDxZiZD;;_OMp`sVcKH:JAqe$dA');
define('LOGGED_IN_KEY',    '%v8mQ!)jYvzG(eCt>)bdr+Rpy5@t fTm5fb:o?@aVzDQw8T[w+aoQ{g0ZW`7F-44');
define('NONCE_KEY',        '$o9FfF{S@Z-(/F-.6fC/}+K 6-?V.XG#MU^s?4Z,4vQ)/~-[D.X0<+ly0W9L3,Pj');
define('AUTH_SALT',        ':]/2K1j(4I:DPJ`(,rK!qYt_~n8uSf>=4`{?LC]%%KWm6@j|aht@R.i*ZfgS4lsj');
define('SECURE_AUTH_SALT', 'XY{~:{P&P0Vw6^i44Op*nDeXd.Ec+|c=S~BYcH!^j39VNr#&FK~wq.3wZle_?oq-');
define('LOGGED_IN_SALT',   '8D|2+uKX;F!v~8-Va20=*d3nb#4|-fv0$ND~s=7>N|/-2]rk@F`DKVoh5Y5i,w*K');
define('NONCE_SALT',       'ho[<2C~z/:{ocwD{T-w+!+r2394xasz*N-V;_>AWDUaPEh`V4KO1,h&+c>c?jC$H');

 


Wordpress-auth-key-secure-auth-salt-Linux-wordpress-admin-security-hardening

Once above defines are set, do not forget to comment or remove old AUTH_KEY / SECURE_AUTH_KEY / LOGGED_IN_KEY / AUTH_SALT / SECURE_AUTH_SALT / LOGGED_IN_SALT /NONCE_SALT keys.

The values are configured one time and never have to be changed, WordPress installation automatic updates or Installed WP Plugins will not tamper the value with time.
You should never expand or show your private generated keys to anyone otherwise this could be used to hack your website site.
It is also a good security practice to change this keys, especially if you have some suspects someone has somehow stolen your wp-onfig keys. 
 

Closure

Having AUTH KEYs and Properly configured is essential step to improve your WordPress site security. Anytime having any doubt for a browser hijacked session (or if you have logged in) to your /wp-admin via unsecured public Computer with a chance of a stolen site cookies you should reset keys / salts to a new random values. Setting the auth keys is not a panacea and frequent WP site core updates and plugins should be made to secure your install. Always do frequent audits to WP owned websites with a tool such as WPScan is essential to keep your WP Website unhacked.

 

 

Remove pre-installed HP, Dell, Asus, Acer, Toshiba not needed default vendor software on a new bought PC notebook quickly with Decrap My Computer

Thursday, April 14th, 2016

remove-default-unneded-software-from-manufacturer-hp-asus-acer-dell-toshiba
While browsing today and looking for software to clean up all the spy software from my corporate HP laptop, I've come across an interesting tool called Decrap which aims at removing Bloatware from a Windows PC / notebook (mirrored here because original software site was down)

So what is Bloatware ?

The term Bloatware (also called jokingly crapware) is term is the one that was coined to describe, the default pre-installed software that comes to you together with Windows pre-installed OS by the hardware manufacturer.
I'm sure anyone who bought brand new branded PC or laptop over the last 10 years have already suffered the unwanted and unnecessery
bunch of software that comes pre-installed freeware programs aiming to help you in your daily work but in reality just slowing down your PC
and showing annoying popups or at best keeping useless in Windows system apptray.

Let me give you an example:

Cleanup (Remove) common ASUS, HP, Dell default  installed unneded (Bloatware) software

Many users may want to uninstall ASUS Crapware software such as ASUS Tutor, ASUS LifeFrame3, ASUS WebStorage and ASUSVibe.

Like Asus, HP computers often come preloaded with useless software from factory, example for this is HP Customer Service enhancements, HP Update, HP Total Care Setup and ProtectSmart.

If you buy Dell PC notebook soon you'll discover that there are several preloaded software (often unnecessery software) such as Dell Stage, Dell Digital Delivery and Dell DataSafe.

Toshiba computers and notebooks contain pre-loeaded "crapware" software from Toshiba.
Just to mention a few of those: Toshiba Disc Creator, Toshiba ReelTime, Service Station, Bulletin Board and Toshiba Assist.

Often there are fingerprint reader programs, Wi-Fi connection managers, Bluetooth managers, Audio Management sofware and other third party vendor software which tend to be not working as good as others softwares from third vendor, so Decrap is to help you to identify and remove these too in a easy GUI manner.

Non-experienced Computer users often leave the bloatware to hang around for even years and only if some relative that is an IT involved person / sysadmin / Even once you're aware that the Bloatware is on the system the ordinary user is hard to remove it as he is scared not to break the system.
Besides that fften this bloatware just soft comes so much integrated into Windows that removing it costs hours of tries and research online on
all the Bloatware components and even then could mislead you so you break the PC. programmer etc. comes home of such users finds out about the happily existing of the useless software on the notebook.


So here is Decrap My Computer coming at place aiming to help to remove the unnecessery Hardware vendor software in few easy (Click, Click, Click Next ..) steps.

decrap-my-computer-clean-up-bloatware-crapware-on-windows-laptop-main-gui

Then decrap does silently all the complex operations and suggestions to make the HP, Dell, Asus, Toshiba manufacturer prebundled software to be stopped and uninstalled.
Decrap My Computer is a freeware, lightweight and easy to use and lets you safely remove crapware and bloatware, or any software, from any Windows PC.

Even for Old computers, Decrap comes handy for the unexperienced avarage user who used his laptop with this useless  default vendors programs silently killing the performance respectively user experience for years.

Using Decrap is quite intuitive PC is scanned for Bloatware and then after a backup Windows Restore Point is offered you're offered to review and Uninstall the unwanted softwares. There is also an automatic mode but those one still could be a bit dangerous, so use the automatic mode only on multiple machines with the same model  / brand notebooks that comes prebundled with same sofware after testing and confirming the automatic mode on 1 initial machine will not break up some needed functionality.

decrap-your-pc-clean-up-windows-from-hp-dell-toshiba-asus-bloatware-unuseful-programs

Here is few screenshots of the tool in action:

decrap-choose-what-default-laptop-manufacturer-software-you-want-to-clean-from-new-bought

Another good alternative (since decrap seems to be not maintained anymore) as I just leardned from Natasha Myles (thanks for pointing me about the broken link to decrap website) is SpeedUpPC more on speeding up old PC or laptop is her article 

A meaningless life – And Ulcer one Heavy Cross I have to wear

Sunday, September 30th, 2007

Suffering from Ulcer gives you so much pain and discomfort and makes you so irritated and nervous. That often you think what the crack, why I ever live. I don't want this suffering anymore but want peace and confort, but I have to bear the heavy cross as the Lord Jesus Christ suffered even worser for our salvation.

Suffering from Deodenum Ulcer is one of the things I don't wish you to suffer from. I've been struggling with this diasease already for years and at certain times when you get worsened you get totally out of your mind!
You can do a lot of things and say a lot of things which eitherwise wouldn't because of this terrible Ulcer diasese but I pray the Lord to forgive me for I have hurted many people because of the sickness. People who suffer from Ulcers are more easy to irritating. Sometimes I wonder why I have to suffer with this Ulcer, after all I'm striving for the good and believe in Jesus Christ who healed ALL kind of diaseses
I know i've done a lot of sins and break up God's commandment and I deserve to suffer but still its hard to accept..

 Oh God have mercy

My E-Marketing Report Final Godaddy.com Versus Enom.com for Download (Godaddy.com compared to Enom.com)

Monday, April 4th, 2011

Some few months ago, I’ve posted some study materials for e-marketing & commerce course (discipline) that I followed in Arnhem Business School (ABS)
Apart from that I had a final assignment which was supposed to be handed in some few weeks before the begging of the Christmas break.

The Emarketing assignment’s aim was to make a comparison of two websites which are operating in the same or very similar business field

The report’s goal was to present to the E-marketing teacher which in my case was Peter Stemers that the student has been acquainted with the basic theories of Emarketing.
The project was actually rather easy and the main issue to build up a project like this is the start up to complete it you just need to put a start and persist in expanding the document.

As the topic was very interesting to myself I started quite early in preparing my assignment (just a few weeks after it was assigned).

I’ve considered my profound interest into Information and Computer Technology (ICT) and decided to create a report which evaluates two websites which are into the IT sphere.
After a examination over a few possible domain names like for example:
Verizon – verizon.com and AT&T – att.com
1& 1and1.co.uk and Godaddy etc.

I’ve finally set my websites to compare choice on: Godaddy.com and enom.com

The criterias for selection of Godaddy and Enom as a target companies to compare their online business was as follows::

1. Both Godaddy and Enom are into the same business online industry, ( e.g. domain selling, reselling, blog hosting, webhosting, SSL certificates, online presence Search Engine optimization etc.)
Some other selection factor that convinced me to choose exactly Enom.com and Godaddy were that this are the biggest companies in the domain names selling IT sector and even better the Domain Selling industry has a tight relation to the History of how the Internet emerged.

The report became really thoroughful, the Godaddy vs Enom emarketing report has the size of 59 pages. Officially the study criterias has been that normally the usual student emarketing reports contains about 15 to 20 pages, however as the business products and services that this huge internet domain reseller companies has, I was forced to exceed the set teacher limitation of 20 pages and do it in 59 pages.

I’ve handed in my emarketing report and Peter Stemers graded it with 8.5 points from 10 possible (which by the way is quite a high mark for Arnhem Business School)

By the wat the E-marketing course was quite a silly one though for people that are not have an avarage computer knowledge and interest into Internet Commerce it was okay.

To read the table of contents of the Report comparison Enom compared to Godaddy click over here
Here is also my Emarketing Final Report Godaddy.com vs Enom.com (Godaddy.com compared to Enom.com) in both PDF and DOC, I hope this reports will be helpful to some marketing researchers out there to get an estimate on how the two companies are performing in the domain selling and reselling business:

1. Download My Emarketing and E-commerce report Godaddy Versus Enom.com (Godaddy Compared to Enom.com) doc version

2. Download E-marketing report Godaddy.Com VS Enom.Com (Godaddy.com Compared to Enom.com) in PDF

Compiling this Emarketing report costed me a lot of effort and time, the overall completion of the report has took me about a two weeks time, whether each day I worked a couple of hours on it.
I express also my big thanks to Alex Petrov (a friend of mine) for helping me read and review the report and fix some minor errors in sentence structures and my language of expression.

The Godaddy VS Enom Emarketing report outlines, numerous pitfalls that both Enom Company and Go Daddy has done in terms of SEO, Emarketing, user friendliness and usability

I believe this report could be really helpful for the these two competitive companies and could help them improve both their user image, their accessibility and Search Engine indexing.
On the other hand the report could be a good example for (HAN – Arnhem Business School E-Marketing) students on how to write a good looking Emarketing report to give themselves a pass.

An interesting fact is that before I decide to publish the report online and make it available to everyone I tried a known selling marketing report, I tried to offer to both Godaddy.Com and Enom.Com to sell them this report by sending the offer to their marketing and sales guys.
Enom.com has returned me an email, that they will look forward to my request, whether with Godaddy I have received an email by Go Daddy founder and CEO Bob Parons and the COO Warren Adelman

I will present you here the reply just to show you how impodent this mans are! My offer to sell them this great report for the symbolic sum of 200 EUR which will help their companies grow was considered I quote: “Unsolicated Report”.
Below I present you my offer email plus the impudent reply email by GoDaddy’s CEO and CEO:

Mysql: How to disable single database without dropping or renaming it

Wednesday, January 22nd, 2014

mysql rename forbid disable database howto logo, how to disable single database without dropping it
A colleague of mine working on MySQL database asked me How it is possible to disable a MySQL database. He is in situation where the client has 2 databases and application and is not sure which of the two databases the application uses. Therefore the client asked one of the database is disabled and wait for few hours and see if something will break / stop working and in that way determine which of the two database is used by application.

My first guess was to backup both databases and drop one of them, then if it is the wrong one to restore from the SQL dump backup, however this wasn't acceptable solution. So second I though of RENAME of database to another one and then reverting the name, however as it is written in MySQL documentation RENAME database function was removed from MySQL (found to be dangerous) since version 5.1.23 onwards. Anyhow there is a quick hack to rename mysql database using a for loop shell script one below:

mysql -e "CREATE DATABASE \`new_database\`;"
for table in `mysql -B -N -e "SHOW TABLES;" old_database`
do
  mysql -e "RENAME TABLE \`old_database\`.\`$table\` to \`new_database\`.\`$table\`"
  done
  mysql -e "DROP DATABASE \`old_database\`;"

Other possible solution was to change permissions of Application used username, however this was also complicated from mysql cli, hence I thought of installing and using PHPMyAdmin to make modify of db user permissions easier but on this server there wasn't Apache installed and MySQL is behind a firewall and only accessible via java tomcat host.

Finally after some pondering what can be done I came with solution to request to disable mysql database using chmod in /var/lib/mysql/data/, i.e.:

sql-server:~# chmod 0 /var/lib/mysql/databasename

Where databasename is the same as the database is named listable via mysql cli.

After doing it that way with no need to restart MySQL server database stopped to appear in show databases; and client confirmed that disabled database is no longer needed so we proceeded dropping it.

Hope this little article will help someone out there. Cheers :

The Ascension of our Lord Jesus Christ feast in Bulgarian Orthodox Church

Friday, June 3rd, 2011

Ascension of Christ Orthodox Icon, Voznesenie Hristovo ikona, Vyznesenie Hristovo icona

On 2 of June this year 2011, our Bulgarian Orthodox Church has marked one more bright feast (one of the 12 chief (God’s) feasts).

The Spiritual Joy is great as our Saviour has Ascended to Heaven 40 days after his Glorious Resurrection in front of the amazed desciples, and crowd of people who were with them.

An Angel has also told the people testifing our Lord’s ascension that the Second Coming of our saviour will take place in the same manner as his Ascension.

Here is some passages from the Gospel of Luke 24:50-53

50 Then he led them out as far as Bethany, and lifting up his hands he blessed them.
51 hile he blessed them, he parted from them and was carried up into heaven.
52 And they worshiped him and returned to Jerusalem with great joy,
53 and were continually in the temple blessing God.

It’s a tradition in some Orthodox Churches that the Paschal Greeting (Christ is Risen / Hristos Voskrese / Hristos Anesti etc.) is substituted with the greeting:
Christ has ascended by the person greeting, while the respondant confirms answering with Truly he has ascended

This Ascension greeting is not that deeply routed among Christians as the Pashcal greeting, though it’s very truthful and beautiful, to use it instead of the standard daily Hi greeting 😉

The whole following week after Ascension’s feast has been arranged by the Church to be a feast week commemorating our Lord Christ’s glorious Ascension (in his glorified body) to Heaven and sit in the right hand of God.

There is a local village hear in Bulgaria near a village called Spasovo – Saviour’s which has a Church called The Ascension of Christ

In this small village there is a spring which does start flowing only on the date of the Ascension (celebrated on a different date every single year)!!!
That’s amazing God miracle given to strengthen our faith as a confirmation that the Ascension of God’s Son and our saviour Christ is a real event that happened!

There is a false belief seriously accepted in many non-devoted Orthodox Christians who does not know well the Orthodox Christian faith, that on the date of The Ascension the so called Spasov Den (in Bulgarian) – Day of the Saviour , the dead who are in heaven and hell are allowed to get out of Heaven or Hell (for a temporary break) and be a bit closer to the living.
Many people who believe this insanity instead of visiting a Church and being joyful for the Ascension of Our saviour do go to the city graves and spends few hours, crying or remembering the dead …
This kind of believe is firmly non-orthodox and is taken from ancient paganism beliefs.

With all this said I find it important to say few words on why the Lord Jesus Christ has ascended?

The answer to this question gives Christ himself, as he says in the Gospel of John – Chapter 16

7 Nevertheless I tell you the truth;
It is expedient for you that I go away:
for if I go not away, the Comforter will not come unto you;
but if I depart, I will send him unto you.

Here is a part of the Troparion for Ascension that is being sing in the Church:

When You fulfilled the dispensation for our sake,
and united earth to heaven:
You have Ascended in Glory, oh Christ our God
not being parted from those who love You,
but remaining with them and crying:
I am with you, and no one will be against you!

Christ has Ascended to all Orthodox Christians!

Speed up your DNS resolve if your Internet Service Provider DNS servers fail or resolve slowly / Privacy concerns of public DNS services use

Wednesday, March 30th, 2011

In my experience with many network Internet Service Providers by so far I’ve encountered a lot of DNS oddities and therefore surfing (web) and mail slowness.

It’s sometimes very irritating especially in cases, when I use my internet over Wireless public or university wireless networks.
In principle many of the Wireless routers which distribute the internet especially in organizations are badly configured and the slowness with DNS resolvings is an absolute classic.
If you haven’t encountered that slowness in opening web pages when connected from your University’s canteen, whether it’s fill with people for the lunch break, then I should say you’re really lucky!

My personal experience with this bad configured devices DNS services has been quite negative and every now and then I use to set and use public DNS servers like OpenDNS and Google DNS

Very often when I connect to a wireless network with my notebook running Debian Linux and the internet is too slow in opening pages I automatically set the Google or OpenDNS servers as a default DNS IP resolving servers.

1. DNS IP addresses of Google Public DNS are:

8.8.8.7
and
8.8.8.8

2. OpenDNS Public DNS servers has the IP addresses of:

208.67.222.222
208.67.222.220

I do set up and use the upper public DNS services addresses via the commands:

3. Set and use Google Public DNS services on my Linux debian:~# cp -rpf /etc/resolv.conf /etc/resolv.conf.orig
debian:~# echo "nameserver 8.8.8.7n nameserver 8.8.8.8 n" > /etc/resolv.conf;

I first create backu pof my resolv.conf under the name resolv.conf.orig just to make sure I can revert back to my old DNSes if I need them at some point.

If you prefer to use the OpenDNS services for some let’s say privacy reasons, you do it in the same manner as in the above commands, you only change the IP addresses. 4. Configure and use the OpenDNS public DNS services

debian:~# cp -rpf /etc/resolv.conf /etc/resolv.conf.orig
debian:~# echo "nameserver 208.67.222.222n nameserver 208.67.222.220 n" > /etc/resolv.conf;

Of course using Public DNS services has it’s disadvantages over the domain resolving speed up advantage.
One major issue is that Public DNS services are running on a top of a cloud and if you have red my previous article Cloud Computing a possible threat to users privacy and system administrator employment you might be agaist the idea of using a services which are powered by cloud.

The other primary concern is related to your SECURITY and a PRIVACY by using Public DNS networks, you risk that your Public DNS provider might use some DNS spoof techniques to mislead you and resolve you common domain names which usually resolve to let’s say 1.1.1.1 to let’s say 1.5.5.10

Even though this kind of practices on a side of a public DNS provider is not a likely scenario the possible implications of Public DNS providers using DNS forgery to fool you about domain names locations is a very serious issue.

As public DNS providers does contain again the good old philosophy of cloud computing embedded in themselves and they strive to become some kind of a standard which people might vote to adopt and use, the future implications of a wide adoption of Public DNS servers might be a terrible thing on internet users privacy!!!

Just think about a future scenario where we users of the Internet are forced to use a number of public DNS servers in order to use the Internet!
Usually a very huge companies are possessing the Public DNS services and do pay for the tech equipment required for building up the cluster clouds which provide the DNS services and therefore, if in the short future public DNS becomes a fashion and (God forbid!) a standard which shifts up the regular ISP DNS servers to resolve domains to IPs then it will be terrible.

The corporations which does own the Public DNS service/s might have a direct control over filtering and censoling information posted on any website on the internet.
Even worser if the world decides to adopt public DNS services somewhere in the future this means that large corporations owning the open dns cluster or clusters will be able to check each and every resolving made by any user on the net.
If you think closely such an information possessed by a company is not the best thing we want.

So let me close up this article, I’m not a fan and an evangelist who preaches the use of Public DNS services. Right on Contrary I do honestly hate the idea behind public DNS.
Nevertheless apart from my personal opinion I’m a practical person and using the public DNS servers every now and then when this will accelerate my access to the internet is still an option I do enjoy.

Maybe it’s time for a free software project (a tor like), which will provide users with an OpenDNS alternative which will run on hobbyist computers around the globe (just like with tor).

What’s rather funny is that the loud name OpenDNS is a big lie in reality OpenDNS is not opened it’s a company owned closed source service 😉
