[MSIE Patch] Microsoft Releases Critical Internet Explorer Security Patch

Microsoft has released the Security Patch for a recently discovered critical security bug in Internet Explorer. The flaw in Microsoft’s Internet Explorer could allow criminals to take control of people’s computers and steal their passwords, internet experts say.

Microsoft in its description for the security update says

This security update resolves a publicly disclosed vulnerability. The vulnerability could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Following this, many security advisors had asked users to stop using Internet Explorer till a patch is released. 

Microsoft has now released an out of turn patch for this Serious Security Flaw. You can grab this update if you have Automatic Updates turned on or by going to http://update.microsoft.com. I would suggest everyone using Windows to apply this patch immediately.

[How-To] Flush DNS Cache

If you are a developer who often has to test same application deployed on different servers, the various options you have are

1.) Modify your HOSTS file to point to a new IP. You can learn more about modifying HOSTS file by reading previous posts on HOSTS file ( Microsoft Windows: More fun with the HOSTS file and Block Websites of your choice without any Software)

2.) Modify the DNS Entry of your Website. This is useful if you have testers who are not technically savvy doing the testing. In such a scenario all you need to do is modify the DNS entry and the new IP is reflected as soon as the change happens.

However, if you are having issues with the DNS IP Resolution and if even after a change on your DNS Server, the new IP is not getting reflected, its time to Flush the DNS Cache. 

DNS Resolution of My Website is Cached? How can i Clear this Cache?

Follow the Steps below

1.) In your windows machine, open the command window by going through Start –>Run and type Cmd.

Initiate the command window

2.) At the Command Prompt, type ipconfig /flushdns as shown below in the figure.

3.) Your DNS Cache is now flushed. What this means is, that your computer will now make a new request to your DNS Server for getting the IP Address. 

The above listed trick lets you flush the DNS Cache from the local resolver of your computer. However, the DNS Entry might still be cached at the DNS Server. 

How Can i Stop the Local DNS Resolver from Caching at All?

Yes. If you make frequent changes to your IP Address and would like to keep the DNS Cache Resolver away from Caching the entries, you can stop the service by typing net stop dnscache at the command prompt.

In order to start the service again, type net start dnscache.

You can even tweak Windows Registry to modify the DNS Caching behaviour

You can modify the behavior of the Microsoft Windows DNS caching algorithm by setting two registry entries in the

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters registry key.

The MaxCacheTtl represents the maximum time that the results of a DNS lookup will be cached. The default value is 86,400 seconds. If you set this value to 1, DNS entries will only be cashed for a single second. MaxCacheTtl needs to be a new DWORD.

MaxNegativeCacheTtl represents the maximim time that the results of a failed DNS lookup will be cached. The default value is 900 seconds. If you set this value to 0, failed DNS lookups will not be cached. MaxNegativeCacheTtl needs to be a new DWORD.

How Do I Flush DNS Cache in Linux?

In Linux, DNS Cache is managed by a service called nscd. To restart the nscd daemon, use the command `/etc/init.d/nscd restart`.

[How-To] Restrict your Adsense Publisher ID from being used by Porn Websites

As a Adsense publisher you need to adhere to a Adsense Usage Policy. One such policy included within is about not showing your Adsense Ads in websites which include Porn or violent content. However, even though you might not have any intentions of showing ads in such websites, its possibe that your Adsense Publisher ID gets used by tricksters for showing Adsense Ads in such websites. This though, wont give any straight benefit to the website publisher, but it can cause serious damage to your Adsense Profile, in worse case, can even lead to suspension of your Adsense Account.

If you are wondering how can your Publisher ID be exposed to the outer world, well, the answer is very simple and straight. All someone has to do is view the source of the webpage where you are showing Adsense Ads to get your publisher ID. Later, any trickster can simply use the same Publisher ID for showing ads. 

This post describes a step by step process of protecting your Adsense Publisher ID from being used by such tricksters. In order to protect your account, follow the steps below.
