It is possible that you might like a favicon (yes the logo icon that is displayed in the browser tab) of a certain website. Now, normally most of the websites store it in the form of favicon.ico in the root directory of any website. So, you can just type in: http://domain.com/favicon.ico and download it when it appears in the browser.
But, not all the websites store it this way. If you find it hard – let it be done by Google. Just type in the following link in the web browser – and it will show you the favicon.ico:

Replace domain.com with the actual domain from which you’d like to download the favicon from.

Set WshShell = CreateObject("WScript.Shell") MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId")) Function ConvertToKey(Key) Const KeyOffset = 52 i = 28 Chars = "BCDFGHJKMPQRTVWXY2346789" Do Cur = 0 x = 14 Do Cur = Cur * 256 Cur = Key(x + KeyOffset) + Cur Key(x + KeyOffset) = (Cur \ 24) And 255 Cur = Cur Mod 24 x = x -1 Loop While x >= 0 i = i -1 KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput If (((29 - i) Mod 6) = 0) And (i <> -1) Then i = i -1 KeyOutput = "-" & KeyOutput End If Loop While i >= 0 ConvertToKey = KeyOutput End Function
Now run the file “productkey.vbs”. You should see something like this:
Note it down and save it somewhere. Good luck.

Internet connected Linux servers are always vulnerable to exploitation by the hackers/intruders. One of their common attack is through SSH. By default SSH servers are configured to listen to port 22 for SSH connection. Changing the port to something else will definitely add an additional measure in securing the server.
How to Change Default SSH port 22 to something else:
- Connect to your server via SSH (your ssh port is still 22) as the root user.
- Run this command: # vi /etc/ssh/sshd_config
- Find out this line: # port 22
- Delete the hash “#” sign from the beginning of the line and change the port to something else. Note down this new port very carefully. You’ll need to use this port for the SSH connection from the next login.
- Save the file and exit.
- Restart the SSH service by executing this command: # service sshd restart
Now disconnect and try reconnecting with the new SSH port. Make sure you memorize the new port number or note it down somewhere.
