Gmail Advanced Settings

noreply@blogger.com (vsara90) — Mon, 28 Feb 2011 07:30:00 +0000

Hi friends.. Every one has a gmail account. So, there should be good privacy and security when we use that. Now Gmail provides advanced options that makes more security to all users.

Using 2 step verification

It makes our account to be more secure.

Why you should use 2-step verification

2-step verification adds an extra layer of security to your Google Account by requiring you to have access to your phone – as well as your username and password – when you sign in. This means that if someone steals or guesses your password, the potential hijacker still can't sign in to your account because they don't have your phone.

How you sign in with 2-step verification

When you want to access Google products from your browser, go to that product and enter your username and password.
You'll next be prompted to enter your verification code, which you'll get from your phone. You'll only have to do this once every 30 days if you so choose.
Soon after you turn on 2-step verification, non-browser applications and devices that use your Google Account (such as Gmail on your phone or Outlook), will stop working. You'll then have to sign in using your username and a special password you generate for this application. (Don't worry, you'll only have to do this once for each device or application.)

What you’ll need

While 2-step verification requires some web savvy, you only need a few basic items:

A phone that is usually available to you when you sign in. This could be:
- A standard phone (landline or mobile)
- Any Android device, BlackBerry device, iPhone, iPod Touch, or iPad that can run the Google Authenticator application
A backup phone that you can use if you lose access to your primary phone. This could be:
- A work or home phone (landline or mobile)
- The phone of someone you trust, like a friend or family member.

How to get started

Go to your Accounts settings page and look for the Using 2-step verification link. If you have the link, click it and start the setup process.
If you do not see the link and you are a Google Apps user, you might have to access the 2-step verification setup through a special URL. It is also possible that your domain administrator has not yet set it up for your organization. Check with your domain administrator to find out.

noreply@blogger.com (vsara90) — Tue, 18 Jan 2011 18:13:00 +0000

Fix svchost.exe using 100% CPU / Memory

First of all, to identify if you have this problem you need to press CTRL+ALT+DEL all at the same time, go to the “Processes Tab” and then press “Mem Usage”. If you have this svchost.exe memory leak bug after about 1 minute you will see that the amount of memory usage svchost.exe uses will keep increasing until CPU becomes 99 or 100%. Below is an example of what this looks like:

How to stop svchost.exe using up 100% system resources (Windows XP Only):

Visit the Microsoft website and Download Windows Update v3 WindowsUpdateAgent30-x86.exe and save it to your C:\ drive
Download this file fix_svchost.bat (right click and choose save as..) and save it to your C:\ drive
Download this file WindowsXP-KB927891.exe and save it to your C:\ drive
Reboot the computer and log in to Windows XP in safe mode. To do this, press F8 just before the WindowsXP logo shows up during boot and press up to choose “Safe Mode”
Once Windows has loaded and you have the option of which user account to use, log on as “Administrator”.
Click Start > Run, choose the Browse button and find the fix_svchost.bat file you saved before, press Open, then OK.
A black screen will pop up and white text will scroll past. Wait for this process to finish as it could take several minutes. It will close itself when its finished.
Once the black screen disappears, Click Start > Run, choose the Browse button and find the WindowsUpdateAgent30-x86.exe file you saved before, press Open, then OK. Follow the prompts as it installs.
When Windows Update Agent finishes installing, Click Start > Run, choose the Browse button and find the WindowsXP-KB927891.exe file you saved before, press Open, then OK. Follow the prompts as it installs.
Reboot the computer

Control PC with Email or SMS

noreply@blogger.com (vsara90) — Wed, 12 Jan 2011 17:16:00 +0000

It’s a long weekend and you’re happy because you’ll get to spend the next three days with your family. You left the office in an excited mood but as the cab was approaching home, you suddenly realized that you forgot to shut down the Office PC. Oops!

It’s a sinking feeling because there’re so many confidential documents on the computer and since most of your trusted colleagues have also left for the day, there’s no point calling them for help.
So what do you do? Drive back to Office? Well that’s not required – just take out your cell phone or switch on the laptop at home, send an email (or an SMS or a tweet) and that will instantly lock your Office workstation. And if you share the same computer with multiple people, you can use another email command to remotely log off or even shut down the computer from anywhere in the world.

There’s no magic here, it’s the power of TweetMyPC utility that lets you remote control your computer from a mobile phone or any other Internet connected computer.
It works like this. You first install the free TweetMyPC utility on any Windows PC and associate your Twitter account. The app will silently monitor your Twitter stream every minute for any desktop commands and if it finds one, will act upon it immediately. The initial version of TweetMyPC was limited to basic shutdown and restart commands, however the current v2 has a far more robust set of commands, enabling a far more useful way of getting your PC to carry out certain tasks especially when you’re AFK (Away From Keyboard).
Before we get started, it may be a good thing if you can set up a new twitter account for remote controlling your desktop and also protect the status updates of this account to ensure better security.
Protecting the account means that you prevent other users from reading your tweets which in this case are email commands that you sending to the computer. To protect your Twitter profile, log in to Twitter with the credentials you want to use, click Settings and check the box next to “Protect my Updates”.
Let’s get started. Install the TweetMyPC utility of your computer and associate your Twitter and Gmail account with the application. It will use Twitter to receive remote commands (like shutdown, log-off, lock workstation, etc) from while the email account will be used for send your information (e.g., what process are currently running on your computer).

How to Send Commands to the Remote Computer

Now that your basic configuration is done, it’s time to set up a posting method. You can use email, SMS, IM, web or any of the Twitter clients to send commands to the remote computer.
By Email: Associate you Twitter account with Posterous (auto-post) and all email messages sent to twitter@posterous.com will therefore become commands for the remote computer. (Also see: Post to Twitter via Email)
By SMS: If you live in US, UK, Canada, India, Germany, Sweden or New Zeleand, you can send associate Twitter with your mobile phone (see list of numbers) and then control your remote computer via SMS Text Messages.
By IM: Add the Twitter bot – twitter@twitter.com – to your list of Google Talk buddies and you can then send commands via instant message.
By Web:If you are on vacation but have access to an internet connected laptop, just log into the Twitter website and issue commands (e.g., shutdown or logoff) just as another tweet.

Download Files, Capture Remote Screenshots & more..

While the TweetMyPC is pretty good for shutting down a remote computer, it lets you do some more awesome stuff as well.
For instance, you need to download an unfinished presentation from the office computer so that you can work on it at home. Or you want to download a trial copy of Windows 7 on the Office computer while you are at home.
Here’s a partial list of commands that you can use to remote control the PC – they’re case-insensitive and, as discussed above, you can send them to Twitter via email, SMS, IM or the web.
Screenshot : This is one of the most useful command I’ve come across after the shutdown command. Want to know what’s happening within the confines of your PC when you’re not around? Just tweet screenshot and TweetMyPC will take a screenshot of your desktop and post it to the web (see example).
ShutDown, LogOff, Reboot, Lock : The function of these useful commands is pretty obvious from their names.
Standby, Hibernate : Don’t want to shutdown the remote PC? Save power by entering standby mode with this command. Or hibernate your PC with a tweet, thereby saving even more power.

Download : You can download any file from the Internet on to the remote computer using the download command. For instance, a command like download http://bit.ly/tCJ9Y will download the CIA Handbook so you have the document ready when you resume work the next day.
GetFile : The Download command was for downloading files from the Internet onto the remote computer. However, if you like to transfer a file from the remote computer to your current computer, use the GetFile command. It takes the full page of the file that you want to download and will send that you as an email attachment. If you don’t know the file page, use the command GetFileList to get a list of file folders on that drive.
GetProcessList : This is like a remote task manager. You’ll get a list of programs that are currently running on the remote computer along with their process IDs. Send another command kill to terminate any program that you think is suspicious or not required.
Conclusion:
TweetMyPC is a must-have utility and you never know when you may need it. And if you have been trying to stay away from Twitter all this time, the app gives you a big reason to at least create one protected account on Twitter.

That said, there’s scope for improvement. For instance, the app will wait for a minute to check for new messages in your Twitter stream so it’s not “instant”. The developers can actually increase that limit because the Twitter API now allows upto 100 checks per hour.
And since the app is dependent on Twitter and Gmail, it will not work during those rare fail-whale moments.

Happy New Year!
