How to prevent website from being hacked into

[MistiBaban]

I need help ??
I am building a webpage in simple HTML/Java code.
But I want to shutdown visitor's machine, when cause username/password error.
Is it possible ????????

This doesn't belong in the Cafe forum; it belongs in either Java or HTML. But why do you want to be so drastic as to shut down a visitors computer? Most websites go with the standard of, y'know, letting the user know there was a mistake. THis sounds very vicious.

I know, sir
But someone try to hack the administrative password.
He use to try with wrong password above 25 times per day.
I already said in this page that if anyone use to enter with wrong username/password; virus will shutdown his/her machine.
So please help me.
I don't want to hurm the machine with virus; just shutdown using cmd prompt.

I agree with Ganon,

Maybe you want to close the user's browser?
Even so, there will be a message that pops up stating that the JavaScript is attempting to close the browser and the user has the option to cancel.

You could try to set a "Time-Out" period. But this would require Server Side implementation.

What are you using to developing your application?

I use the following quote
[code=html]
<form>
<p>ENTER USERNAME :
<input type="text" name="text2">
</p>
<p> ENTER PASSWORD :
<input type="password" name="text1">
<input type="button" value="Check In" name="Submit" onclick=javascr ipt:validate(te xt2.value,"User name",text1.val ue,"Password") >
</p>

</form>[/code]
[code=javascript]
<script language = "javascript ">

function validate(text1, text2,text3,tex t4)
{
if (text1==text2 && text3==text4)
load('success.h tm');
else
{
load('\Fail.htm l');
}
}
function load(url)
{
location.href=u rl;
}
</script>[/code]

Please use code tags when posting code:

&#91;CODE=javas cript]
Your Javascript code here...
[/CODE]

Looking at your code, it is too easy to log in. You shouldn't be using JavaScript for login. Anyone with even a basic knowledge of JavaScript will know what the username and password is.

Use a server-side language for login.

Normally when validating a user's password we check it against a database of some sort that is stored on the web server.

I'm not sure what you are trying to accomplish with what you are doing in this code.

I think what you are trying to do is going to require some more intensive web programming.... specifically Server Side coding to accomplish a proper login process.

I've moved your question to the JavaScript forum to see if anyone has more suggestions for you. I've also renamed your thread to better reflect your problem.

I understand what both of U said, sir
Thanking you for explain me
I have not so good idea on it but I want to learn it by trial and error methods

I am using a free web so I think I am not able to use Server Side coding.
It is a project of me but I want to make it really good

Can you help me to rearrange this code in this way that
When I enter the Username/Password into the form
It check the java script from another html page, which will never become in front, so no one could see the code if it.

I don't know how to do this without using Server Side code.
Look into what your web provider allows....maybe it'll let you use something like ASP or something?

I have little idea on it but.......
Can I redirect the form, when press the submit, into another page where the check will be done by java script and allow or not allow to the private page on correct and wrong password respectively.

This can't be done with JavaScript. The JavaScript source can easily be seen.

Some free web hosts do include support for a server-side language, usually PHP.
