How to Block a Website?
Some times it becomes necessary to block a website on our Computers for one or other reason.You can easily and effectivily block access to a website by adding it to your Windows HOSTS file.Once the website is blocked in the HOSTS file,it will not appear in any of the browsers.That is,the website becomes completely unavailable.
1.Go to your HOSTS file which is located at:
C:\WINDOWS\SYSTEM32\DRIVERS\ETC for Vista and XP
C:\WINNT\SYSTEM32\DRIVERS\ETC for Win 2000
C:\WINDOWS for Windows 98 and ME
2. Open HOSTS with Notepad.
The default Windows HOSTS looks like this:
______________________
# Copyright © 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a “#” symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
#
127.0.0.1 localhost

3. Directly under the line that says 127.0.0.1 Localhost, you will want to type:
127.0.0.1 name of the URL you want to block
For example to block the website MySpace.com, simply type:
127.0.0.1 myspace.com
127.0.0.1 www.myspace.com
Other parts of MySpace could be blocked in a similar way:
127.0.0.1 search.myspace.com
127.0.0.1 profile.myspace.com
etc etc etc…
It is necessary to add a website with and without the “www.”. You can add any number of websites to this list.
4. Close Notepad and answer “Yes” when prompted.
5. After blocking the website, test it in any of the browser.If every thing is done as said above,the website must not appear in any of the web browsers. You should see a Cannot find server or DNS Error saying: “The page cannot be displayed”.
Some people suggest that your add a website to the Internet Explorer ‘Privacy’ settings. This does not block a site. It only stops that site from using cookies.

Once in the port scanner type in your Victims ip that you got from step 1.
It will ask you todo a range scan or a full scan (SELECT REANGE SCAN!) It will ask for conformaition you have to use a capital Y or a capital N! Now enter 79 for lowest port and 81 for highest hit enter than hit cap Y.
[X] = Closed
[X] Vulnerable = Open

If port 80 is open your on your way to crashing!!
Ok open Up rDos that you download.
Enter your victims ip that we got from step 1.
It will ask you for the port to attack use port 80 that is why we scaned to make sure 80 was open! If it is closed it will not work.
