How to Find the IP Address of a Remote Computer

Most of you may be curious to know how to find the IP address of your friend’s computer or to find the IP address of the person with whom you are chatting in Yahoo messenger or Gtalk. In this post I’ll show you how to find the IP address of a remote computer in simple steps.

I have created a PHP script to make it easier for you to find the IP address of the remote computer of your choice. Here is a step-by-step process to find out the IP address.
1. Download the IP Finder script (IP_Finder.ZIP) that I have created.
2. Open a new account in X10Hosting (or any free host that supports PHP).
3. Extract the IP_Finder.ZIP file and upload the two files ip.php and ip_log.txt into the root folder of your hosting account using the File Manager.
4. You can rename the ip.php to any name of your choice.
5. Set the permission to 777 on ip_log.txt.
Now you are all set to find the IP address of your friend or any remote computer of your choice. All you have to do is send the link of ip.php to your friend or the person with whom you’re chatting. Once the person click’s on the link, his/her IP address is recorded in the file ip_log.txt.
For your better understanding let’s take up the following example.
Suppose you open a new account in X10hosting.com with the subdomain as abc, then your IP Finder link would be

http://abc.x10hosting.com/ip.php

You have to send the above link to you friend via email or while chatting and ask him to visit that link. Once your friend clicks on the link, his IP address will be recorded along with the Date and Time in the ip_log.txt file. After recording the IP address, the script will redirect the person to google.com so as to avoid any suspicion.
To find the recorded IP address check the logs using the following link.

http://abc.x10hosting.com/ip_log.php

The sample log will be in the following format
79.92.144.237 Thursday 07th of May 2009 05:31:27 PM
59.45.144.237 Thursday 07th of May 2009 05:31:28 PM
123.92.144.237 Thursday 07th of May 2009 05:31:31 PM
NOTE: You have to replace abc with your subdomain name.
I hope this helps. Express your opinion and suggestions through comments.

How to Hack an Ethernet ADSL Router

Almost half of the Internet users across the globe use ADSL routers/modems to connect to the Internet however, most of them are unaware of the fact that it has a serious vulnerability which can easily be exploited even by a noob hacker just like you. In this post I will show you how to exploit a common vulnerability that lies in most ADSL routers so as to gain complete access to the router settings and ISP login details.
Every router comes with a username and password using which it is possible to gain access to the router settings and configure the device. The vulnerability actually lies in the Default username and password that comes with the factory settings. Usually the routers come preconfigured from the Internet Service provider and hence the users do not bother to change the password later. This makes it possible for the attackers to gain unauthorized access and modify the router settings using a common set of default usernames and passwords. Here is how you can do it.
Before you proceed, you need the following tool in the process
Angry IP Scanner
Here is a detailed information on how to exploit the vulnerability of an ADSL router.
Step-1: Go to www.whatismyipaddress.com. Once the page is loaded you will find your IP address. Note it down.
Step-2: Open Angry IP Scanner, here you will see an option called IP Range: where you need to enter the range of IP address to scan for.

Suppose your IP is 117.192.195.101, you can set the range something as 117.192.194.0 to 117.192.200.255 so that there exists atleast 200-300 IP addresses in the range.

 

Step-3: Go to Tools->Preferences and select the Ports tab. Under Port selection enter 80 (we need to scan for port 80). Now switch to the Display tab, select the option “Hosts with open ports only” and click on OK.

I have used Angry IP Scanner v3.0 beta-4. If you are using a different version, you need to Go to Options instead of Tools

 

Step-4: Now click on Start. After a few minutes, the IP scanner will show a list of IPs with Port 80 open as shown in the below image.

 

Step-5: Now copy any of the IP from the list, paste it in your browser’s address bar and hit enter. A window will popup asking for username and password. Since most users do not change the passwords, it should most likely work with the default username and password. For most routers the default username-password pair will be admin-admin or admin-password.
Just enter the username-password as specified above and hit enter. If you are lucky you should gain access to the router settings page where you can modify any of the router settings. The settings page can vary from router to router. A sample router settings page is shown below.

 

If you do not succeed to gain access, select another IP from the list and repeat the step-5. Atleast 1 out of 5 IPs will have a default password and hence you will surely be able to gain access.

 

What can an Attacker do by Gaining Access to the Router Settings?

By gaining access to the router settings, it is possible for an attacker to modify any of the router settings which results in the malfunction of the router. As a result the target user’s computer will be disconnected from the Internet. In the worst case the attacker can copy the ISP login details from the router to steal the Internet connection or play any kind of prank with the router settings. So the victim has to reconfigure the router in order to bring it back to action.

 

The Verdict:

If you are using an ADSL router to connect to the Internet, it is highly recommended that you immediately change your password to prevent any such attacks in the future. Who knows, you may be the next victim of such an attack.
Since the configuration varies from router to router, you need to contact your ISP for details on how to change the password for your model.

Hack BSNL Broadband for Speed

If you are a BSNL broadband user, chances are that you are facing frequent DNS issues. Their DNS servers are just unresponsive. The look up takes a long duration and many times just time out. The solution? There is small hack on BSNL for this. Use third party DNS servers instead of BSNL DNS servers or run your own one like djbdns. The easiest options is to use OpenDNS. Just reconfigure your network to use the following DNS servers:

208.67.222.222
208.67.220.220

Detailed instructions specific to operating system or your BSNL modem are available in the OpenDNS website itself. After I reconfigured my BSNL modem to use the above 2 IP addresses, my DNS problems just vanished! Other ‘freebies’ that come with OpenDNS are phishing filters and automatic URL correction. Even if your service provider’s DNS servers are working fine, you can still use OpenDNS just for these two special features. After you hack BSNL DNS servers, you will see a noticeable improvement in your broadband speed.
