Multiple IP banning

[flambor]

Does anybody know of a good IP banning javascript that can ban multiple IPs and works in IE and Netscape?

[brendandonhue]

You can't ban IPs in javascript. JS can not detect a users IP.

!!!WARNING!!!WARNING!!!

I think you can detect a users IP, but if you want to use it to ban a users IP, do NOT use javascript to solve this problem. Instead, use a server-side language, like perl, PHP, asp, .shtml , but [I think :rolleyes: ]a .hactass file would do the job, as well.

why not javascript?
people could just disable javascript in their browsers!

[brendandonhue]

No you can not detect a users IP address using javascript. Netscape does have a way-but its actually using java that is controlled by javascript.

Where can I find a script that will do the job then?

[brendandonhue]

What server side languages do you have access to?

I think this may work. It does in IE, I'm not sure about Netscape. :)

<SCRIPT LANGUAGE="JavaScript">
function ban(){
alert("You are banned from this site!!!");
location.replace("URL"); //URL of the page where they are kicked to
}
var ip = '172.137.3.246';
window.status = "Your IP Address is : " + ip;
if ((ip == "111.11.111.111") || (ip == "222.22.222.222") || (ip == "333.333.333.333"))
{
// Just add the ip address of people who you want to ban to
// the above "if" statement as shown above
ban();
// BE SURE YOU SAVE THE WEBPAGE AS ".shtml", just
// change it from ".html" or ".htm" to ".shtml"
}
</script>

what is the 'var ip' in that script? do i have to change it?

[brendandonhue]

First of all-no that script doesnt work. You skipped the part about REMOTE_ADDR which is the part that actually detects the IP.
Second-the script is not completely javascript. It requires Server-Side-Includes.

Yes, as brendandonhue mentioned, the script that Zero provided will do nothing to ban an IP... You need to GET the users IP before you can ban it...

If you have access to PHP, you would do it like this:

<?PHP
#Add this script to the very top of your page, before any other content...
$ip = $_SERVER["REMOTE_ADDR"]; #get the users IP
$banned = array("111.111.111.111","222.222.222.222"); #set up the IPs to ban, separated by commas (,)

foreach ($banned as $ban) { #loop through the array of banned IPs
if ($ip == $ban) {
header("Location:http://www.yourdomain.com/banned.php"); #send banned IPs to banned.php
}
}
?>

EDIT: code edited to provide an array of banned IPs

does anybody know why this will not work? except for the fact i haven't put my ip in.

ip.shtml (http://homepage.ntlworld.com/michael_naylor/ip.shtml)

[brendandonhue]

Rereat the thread. That script does not do anything as I said above.

And the PHP isnt working because its an shtml file.
if your server supports PHP, use Pyros script and save it as .php.
If it supports SSI, use this script

if i use ssi what do i need to save it as?

[brendandonhue]

shtml

But make sure your server supports SSI.
