i know that this post has not mutch to do with eo
but it is still used for eo ( my online checker script) as i want to get powerchaos.info back online so it can be used
but before i put it back online i need to have a good script that does his work instead a messy script (you will see what is changed as soon it is ready to go live)
i like to know who are the scripters here because i got a small request for them
i am searching for a way to block invalid ip's that get submitted with a form
to give a example
ip 258.12.20.14 is invalid
invalid is 192.168.1.1 (private lan network)
i got already a way to block hamachi ip's
i got in meantime a way to block all invalid ip's but for 1 of other reason it allows a few to get true
would some1 be nice to point me to the error or fix the error for me ?
a own code that does the same would be nice to
demo of below code can be found at
PHP Code:
$validipcheck1 = "^([1-9]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $validipcheck2 = "^([1-2]{1,1})+([0-9]{1,2})+\.([0-9]{1,3})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $hamachiip = "^([5]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $local1 = "^([1]{1,1})+([9]{1,1})+([2]{1,1})+\.([1]{1,1})+([6]{1,1})+([8]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $local2 = "^([1]{1,1})+([0]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $range1 = "^([1]{1,1})+([7]{1,1})+([2]{1,1})+\.([1-2]{1,1})+([6-9]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $range2 = "^([1]{1,1})+([7]{1,1})+([2]{1,1})+\.([3]{1,1})+([0-2]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $subcheck1 = "^([2-9]{1,1})+([5-9]{1,1})+([5-9]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $subcheck2 = "^([0-9]{1,3})+\.([2-9]{1,1})+([5-9]{1,1})+([5-9]{1,1})+\.([0-9]{1,3})+\.([0-9]{1,3})$"; $subcheck3 = "^([0-9]{1,3})+\.([0-9]{1,3})+\.([2-9]{1,1})+([5-9]{1,1})+([5-9]{1,1})+\.([0-9]{1,3})$"; $subcheck4 = "^([0-9]{1,3})+\.([0-9]{1,3})+\.([0-9]{1,3})+\.([2-9]{1,1})+([5-9]{1,1})+([5-9]{1,1})$"; if ((eregi($subcheck1, $ip)) OR (eregi($subcheck2, $ip)) OR (eregi($subcheck3, $ip)) OR (eregi($subcheck4, $ip)) OR (eregi($local1, $ip)) OR (eregi($local2, $ip)) OR (eregi($range1, $ip)) OR (eregi($range2, $ip))) { $sub == 1; }
if ((!eregi($validipcheck1, $ip)) OR (!eregi($validipcheck2, $ip)) OR ( $sub == 1 )) { $proceed = 0; $end = 1; echo "<blockquote> <p> “Server ip adress is Not Allowed , Please fill in a differend ip adress.” </p> </blockquote>"; } else if ((eregi($validipcheck1, $ip)) OR (eregi($validipcheck2, $ip))) { $proceed = 0; $end = 1; echo "<blockquote> <p> “Valid ip match.” </p> </blockquote>"; }
the user who can fix this and can show that it works get free Lifetime Premium hosting from me :P
If you would explain what it is intended to do a little more I would be happy to help. You are just trying to block any ips that are local and hamachi?
indeed
my form submits the server ip ( game server)
and because i know that there are a lot of people ( including bots) that submit wrong ip's
so i like to prevent wrong submision
a wrong ip gives me a lot of server load as my script checks every ip on the provided port to know if it is open or not ( status checking script for private games)
<-- thats what it shows after submision so far
hopely by looking at the above link you got a better idea of what it going be and why i definaly need that ip security
the ip security get used to to prevent local submisions (as best thing ever i saw was 192.168.1.1 as submision ip )
Greetings From PowerChaos
ps: form get submitted and posted into a database and then included in my ip checking script to see if ports are open , thats all it does
All I have to say at the moment is that eregi is a very bad function to use as it is slow and outdated (using str functions is better)... but I fear this topic will be closed and/or locked. If not I will be happy to help tomorrow
EDIT: The echo statements are also not correct formatting, that may be where your problem lies?
tbh that code is pretty clean, clean and short are two very different things.. ill have a look over it if i get a chance for you.. allthough im not the best on eregs..

it does not neeed to be in eregs
it can be kinda the same way or a other way
the only thing that counts for me is that it works and does what it need to do
so it blocks unwanted ip's and invalid ips (like explained above)
Here's a fast write up, I did. I tested it on a few of the IP's you provided and it seems to be working fine.
Here's the PHP Code:
Code:
<?php
$host = "YourHost"; //Server Host
$db_user = "YourDbUser"; //Database User
$db_pass = "YourDbPass"; //Db Password
$connect = mysql_connect($host, $db_user, $db_pass) OR DIE(mysql_error());
$db_name = "YourDatabase"; //Db Name
//Invalid Ip Checker
function check_ip($IP1)
{
global $connect;
mysql_select_db($db_name);
$IP1 = $IP1;
$result = mysql_query("SELECT * FROM invalid_ip WHERE active='1'") OR DIE(mysql_error());
while($row = mysql_fetch_array($result))
{
$StartIP = $row['start'];
$EndIP = $row['end'];
if ($IP1 >= $StartIP && $IP1 <= $EndIP)
{
$IP1 = "0";
}
}
return $IP1;
}
?>
<form action="" method="POST">
<table>
<tr><td>Ip:</td><td><input type="text" name="ip"></td></tr>
<tr><td></td><td><input type="submit" name="check" value=" Check IP "></td></tr>
</table>
</form>
<br />
<br />
<?php
If(ISSET($_POST['check']))
{
global $connect; //Makes the connection variable Global
$ip = mysql_real_escape_string($_POST['ip']); //Grab the Entered IP
$valid_ip = (check_ip($ip) == '0' ? "No" : "Yes"); //Ternary Check of Invalid Ips. Runs off of the function
$ip_nums = explode('.', $ip); //Seperates the $ip variable so it can count the blocks
$periods = count($ip_nums) - 1; // Takes the seperate IP blocks, and counts them, then minus's by 1 to get true value.
//Check to make sure each ip block isnt greater than 255
If($ip_nums[0] > 255 || $ip_nums[1] > 255 || $ip_nums[2] > 255 || $ip_nums[3] > 255)
{
echo 'Sorry Ips can not be larger than 255';
}
ElseIf($periods != 3) //Check Periods to make sure there are only 3 periods.
{
echo "Sorry you don't have enough periods in your IP.";
}
ElseIf($valid_ip == "No")//Runs the Ip check to see if the entered IP is in the invalid list.
{
echo "Sorry the IP you entered is invalid.";
}
Else
{
echo "It worked!!!!";
}
}
?>
Here's the Mysql Table for the invalid IP checker
Code:
DROP TABLE IF EXISTS `invalid_ip`;
CREATE TABLE `invalid_ip` (
`id` int(15) NOT NULL auto_increment,
`start` varchar(20) NOT NULL default '',
`end` varchar(20) NOT NULL default '',
`active` enum('0','1') NOT NULL default '0',
PRIMARY KEY (`id`)
) TYPE=MyISAM;
/* Insert Invalid Ip Ranges that we know of */
INSERT INTO `invalid_ip` VALUES
('1', '192.168.0.0', '192.168.1.255.255', '1'),
('2', '172.16.0.0', '172.31.255.255', '1'),
('3', '10.0.0.0', '10.255.255.255', '1'),
('4', '5.0.0.0', '5.255.255.255', '1');
I had it set up to a form on my test page. But by following the comments, you should be-able to tell what each section does.
Im no master scripter but maybe you can make some good use of this ...
it is a nice script
but the checks are failing
i can not add every single ip range to a txt file to lookup the check
the 3 dot check is missing , the 255+ is missing and the ip range check is missing
but for the rest it is a nice script

Thank you for the code
but you messed up a little part ( the part i quoted :P )
if it works then i let you know , i still need to edit a lot from it as my script got a own database already
but atleast the function/check part is what i need and then i can implent it into my script
Thank you
Greetings From PowerChaos
Thank you Eurion,
i can confirm that this code works like it need to be
i can even block proxy's from submitting and can do a lot more now with the example you provided to me
it is a bit differend code then i was thinking , but atleast it works perfect like it need to be ( easy to add new blocks and to add other security to it )
please send me a pm for the coupon code of the lifetime hosting (so i know if you realy want it ^^ )
i made a new topic so users can request what need to be added or what they like to have added
your code is realy nice and easy
exactly what i needed
in meantime i was finishing the script as the submit script is the most work ( it need a lot of checks :P )

Looking for any Reverse engineering information(finding the Base addr for say player) and locating the offsets ptrs for Cur health etc. I would also love to see a simple example source in C++ of putting those addresses and offsets into action. I'm sure I have the basic idea down on how to do this but I'm not 100% sure how to get it setup correctly.

hope this might be of some use
