Useful and FREE online tools for DNS and Network Troubleshooting

When troubleshooting network or DNS problems related to your website, server or other online services, it can be very useful to have access to online tools that can help you narrow down the problems. W3dt.net's useful online tools can help you with this, most of all they are free.W3dt.net (short for World Wide Web Domain Tools) is an online Network Troubleshooting site dedicated to providing relevant real-time data regarding networks, websites & other technical resources.
Although you can perform some of the tasks w3dt provide from your computer (such as nslookup/dig, ping, traceroute etc..) it can often be useful to able to perform these tasks from different locations to verify the consistency of your Network/Domain and it's behaviour and settings.

Firstly let's note that there are several other Network/Domain Troubleshooting websites around, but w3dt.net has proven to be one of the more satisfactory sites due to it's vast amount of tools & utilities that are all free of charge. Because of this we will be reviewing some of the functionality of the site and what it has to offer.

The site currently has five categories of functionality (and growing) to help you trouble-shoot your Network/Domain:

* Network Tools / Internet Tools
* Web / HTTP Tools
* Ping Tools
* Database Lookup Tools
* General Tools

Network Tools / Internet Tools
These tools are generally the most frequently used tools on the website and contain some of the following features:
DNS Lookup's, Port Scanning, Trace Route's, ARBL Checking (Blacklist / Whitelist Checking), Maximum Transmission Unit Determination, IP Lookups, NetBIOS Scanning plus more.
You can run some of these tasks from your desktop computer but w3dt offers the assurance of real-time results without any interception of data.
For example, a Port Scan from your desktop computer running on a home internet connection will often fail, due to ISP Policy's, proxy filtering, etc…

Web / HTTP Tools
Web / HTTP Tools can be used to test your Domain in real-time and return the most relevant results. Tools such as:
HTTP Header Retrievals, Plain Text Website Conversion, URL/Base64 Encoding & Decoding can be used to help debug your website.
Dave Nedved from w3dt.net also states that other tools such as HTML Validation & Checking is planned for the not to distant future.

Ping Tools
This category basically speaks for itself, w3dt.net has dedicated a whole category for pinging and ping testing. Using this category you can run your own ping tests on any IP/Domain, including http websites, and the ability to ping IP's/Services on open TCP Ports.

Database Lookup Tools
W3dt.net hosts several large databases, such as RFC Lookups, WHOIS Lookups (on almost all domains on the internet), Abuse Contact Lookups, and most impressively (In my opinion, the biggest feature on the site) the DNL (Short for Domain Name Listing). Basically the DNL is a massive online database of every top level domain hosted on the internet. W3dt runs a query program codenamed "Project Cyberdawn" which spiders through the internet collecting information about every .tld (Top Level Domain) on the internet. Currently the DNL contains over 92 million domains, there is a good chance your domain & information about it will be in the database also.

General Tools
Most of the general tools listed on w3dt.net are used by I.T. gurus & technicians… tools such as IP Conversion, Hash Testing, and Random Character / Password Generation can be found here. For instance these tools are great if your a programmer or web developer, and you wish to see all possible 38 hashes for the query 'dog' and use them to query against your database.

Netbios Hacking Guide

THIS NETBIOS HACKING GUIDE WILL TELL YOU ABOUT HACKING REMOTE COMPUTER AND GAINING ACCESS TO IT'S HARD-DISK OR PRINTER.NETBIOS IS THE EASIEST WAY TO HACK A REMOTE COMPUTER.

STEP-BY-STEP HACKING PROCEDURE THROUGH NETBIOS

1.Open command prompt

2. In the command prompt use the "net view" command
( OR YOU CAN ALSO USE "NB Scanner" OPTION IN " IP-TOOLS " SOFTWARE BY ENTERING RANGE OF IP ADDRESSS.BY THIS METHOD YOU CAN SCAN NUMBER OF COMPUTERS AT A TIME).

Example: C:\>net view \\219.64.55.112

The above is an example for operation using command prompt."net view" is one of the netbios command to view the shared resources of the remote computer.Here "219.64.55.112″ is an IP address of remote computer that is to be hacked.You have to substitute a vlaid IP address in it's place.If succeeded a list of HARD-DISK DRIVES & PRINTERS are shown.If not an error message is displayed. So repeat the procedure 2

3. After succeeding, use the "net use" command in the command prompt.The "net use" is another netbios command which makes it possible to hack remote drives or printers.

Example-1:
C:\>net use D: \\219.64.55.112\F
Example-2:
C:\>net use G: \\219.64.55.112\SharedDocs
Example-3:
C:\>net use I: \\219.64.55.112\Myprint

NOTE: In Examples 1,2 & 3, D:,G: & I: are the Network Drive Names that are to be created on your computer to access remote computer's hard-disk.

NOTE: GIVE DRIVE NAMES THAT ARE NOT USED BY ANY OTHER DRIVES INCLUDING HARD-DISK DRIVES,FLOPPY DRIVES AND ROM-DRIVES ON YOUR COMPUTER.THAT IS IF YOU HAVE C: & D: AS HARD DIRVES, A: AS FLOPPY DIVE AND E: AS CD-DRIVE, GIVE F: AS YOUR SHARED DRIVE IN THE COMMAND PROMPT

F:,"SharedDocs" are the names of remote computer's hard-disk's drives that you want to hack. "Myprint" is the name of remote computer's printer.These are displayed after giving "net use" command. "219.64.55.112″ is the IP address of remote computer that you want to hack.

4. After succeeding your computer will give a message that "The command completed sucessfully". Once you get the above message you are only one step away from hacking the computer.

Now open "My Computer" you will see a new "Hard-Disk drive"(Shared) with the specified name.You can open it and access remote computer's Hard-Drive.You can copy files,music,folders etc. from victim's hard-drive.You can delete/modify data on victim's hard-drive only if WRITE-ACCESS is enabled on victim's system.You can access files\folders quickly through "Command Prompt".

NOTE: If Remote Computer's Firewall Is Enabled Your Computer Will Not Succeed In Gaining Accesss To Remote Computer(An Error Message Is Displayed).So Repeat The Procedure 2,3.

HAPPY NETBOS HACKING!!

How to Block Websites ?

Some times it becomes necessary to block a few websites 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.

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 MySpace.com homepage (highly recommended!), 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…

You may need to add sites with both with and without the "www.". Test after blocking to make sure you got it right.

You can add as many sites as you wish to block in this fashion. I, myself, have over 12000 undesireable and dangerous sites in my personal HOSTS file!

4. Close Notepad and answer "Yes" when prompted.

5. Reboot your computer and attempt to access your now blocked website. You should see a Cannot find server or DNS Error saying: "The page cannot be displayed".

----------

Some people suggest that you add a website that you wish to block by adding it to Internet Explorer's Restricted Zone. This does NOT totally block a site. It will only RESTRICT a site from certain actions such as using javascript, Active-X and Java etc.

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.

Proxy Servers and Anonymizers

Proxy is a network computer that can serve as an intermediate for connection with other computers. They are usually used for the following purposes:

• As firewall, a proxy protects the local network from outside access.
• As IP-addresses multiplexer, a proxy allows to connect a number of computers to Internet when having only one IP-address.
• Proxy servers can be used (to some extent) to anonymize web surfing.
• Specialized proxy servers can filter out unwanted content, such as ads or 'unsuitable' material.
• Proxy servers can afford some protection against hacking attacks.

Anonymizers

• Anonymizers are services that help make your own web surfing anonymous.
• The first anonymizer developed was Anonymizer.com, created in 1997 by Lance Cottrell.
• An anonymizer removes all the identifying information from a user's computers while the user surfs the Internet, thereby ensuring the privacy of the user.

Denial Of Service Attack

Its Real,On February 6th, 2000, Yahoo portal was shut down for 3 hours. Then retailer Buy.com Inc. (BUYX) was hit the next day, hours after going public. By that evening, eBay (EBAY), Amazon.com (AMZN), and CNN (TWX) had gone dark. And in the morning, the mayhem continued with online broker E*Trade (EGRP) and others having traffic to their sites virtually choked off.

What is a Denial Of Service Attack?

• A denial of service attack (DOS) is an attack through which a person can render a system unusable or significantly slow down the system for legitimate users by overloading the resources, so that no one can access it.
• If an attacker is unable to gain access to a machine, the attacker most probably will just crash the machine to accomplish a denial of service attack.

Types of denial of service attacks

There are several general categories of DoS attacks.Popularly, the attacks are divided into three classes:

• bandwidth attacks,
• protocol attacks, and
• logic attacks
  

What is Distributed Denial of Service Attack?

• An attacker launches the attack using several machines. In this case, an attacker breaks into several machines, or coordinates with several zombies to launch an attack against a target or network at the same time.
• This makes it difficult to detect because attacks originate from several IP addresses.
• If a single IP address is attacking a company, it can block that address at its firewall. If it is 30000 this is extremely difficult.

Phishing Tools Available Online

Tools that can help people potentially defraud innocent surfers are available for free download on the internet, it has been claimed.

The do-it-yourself kits provide all the essential tools for launching phishing attacks - those that use spoofed emails and fraudulent websites to trick people into giving out personal financial data.

Phishing scams are on the up. Security company MessageLabs has intercepted an average of 250,000 phishing emails a month so far in 2004, compared to just 14 phishing-related emails back in August 2003.

According to anti-virus company Sophos, the DIY kits contain all the graphics, web code and text required to construct fake websites that look like legitimate online banking or shopping sites. They also include spamming software which would let you send out millions of phishing emails as bait for potential victims.

"Until now, phishing attacks have been largely the work of organised criminal gangs, however, the emergence of these 'build your own phish' kits mean that any old Tom, Dick or Harry can now mimic bona fide banking websites and convince customers to disclose sensitive information such as passwords, PIN numbers and account details," said a spokesman for Sophos.

"There is plenty of profit to be made from phishing. By putting the necessary tools in the hands of amateurs, it's likely that the number of attacks will continue to rise."

Surfers that receive a suspicious email that claims to come from an online bank or e-commerce site should delete them and not click on any included links.

What to do when your Orkut Account is Hacked ?

It can be a nightmare if someone else takes control of your Google Account because all your Google services like Gmail, Orkut, Google Calendar, Blogger, AdSense, Google Docs and even Google Checkout are tied to the same account.

Here are some options suggested by Google Support when your forget the Gmail password or if someone else takes ownership of your Google Account and changes the password:

1. Reset Your Google Account Password:
Type the email address associated with your Google Account or Gmail user name at google.com/accounts/ForgotPasswd - you will receive an email at your secondary email address with a link to reset your Google Account Password. This will not work if the other person has changed your secondary email address or if you no longer have access to that address.

2. For Google Accounts Associated with Gmail:
If you have problems while logging into your Gmail account, you can consider contacting Google by filling this form . It however requires you to remember the exact date when you created that Gmail account.

3. For Hijacked Google Accounts Not Linked to Gmail:
If your Google Account doesn't use a Gmail address, contact Google by filling this form . This approach may help bring back your Google Account if you religiously preserve all your old emails. You will be required to know the exact creation date of your Google Account plus a copy of that original "Google Email Verification" message.It may be slightly tough to get your Google Account back but definitely not impossible if you have the relevant information in your secondary email mailbox.

Hack BSNL Broadband for Speed

If you are a BSNL broadband user, chances are that you are facing DNS issues for the last few weeks or so. Their DNS servers are just unresponsive. The lookup takes a long duration and many times just time out. The solution?There is small hack for this. Use third party 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 your router are available in the OpenDNS website itself. After I reconfigured my Linksys router 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 performing this hack you will see a noticeable improvement in your broadband speed.

Change the Title of Yahoo Messenger

Here's how you change the title text that appears at the top of the Messenger window. By default, this is "Yahoo! Messenger", followed by your status. Simply edit the ymsgr.ini file, which you will find in the same folder as the Messenger program, in your Program Files folder. Locate the file and open it in Notepad. Then, at the end, add the following:

[APP TITLE]
caption=YOUR TEXT

Here, "YOUR TEXT" is whatever you want in the title bar. Save the file and close Messenger. When you restart it you will see your text in the title bar.

Change IP Address

How to
change your IP address in less than a minute? The following trick gives you a step-by-step procedure to change your IP address.

1. Click on "Start" in the bottom left hand corner of screen.

2. Click on "Run".

3. Type in "command" and hit ok.You should now be at an MSDOS prompt screen.

4. Type "ipconfig /release" just like that, and hit "enter".

5. Type "exit" and leave the prompt.

6. Right-click on "Network Places" or "My Network Places" on your desktop.

7. Click on "properties".

You should now be on a screen with something titled "Local Area Connection", or something close to that.

8. Right click on "Local Area Connection" and click "properties".

9. Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab.

10. Click on "Use the following IP address" under the "General" tab.

11. Create an IP address (It doesn't matter what it is. I just type 1 and 2 until i fill the area up).

12. Press "Tab" and it should automatically fill in the "Subnet Mask" section with default numbers.

13. Hit the "Ok" button here.

14. Hit the "Ok" button again.You should now be back to the "Local Area Connection" screen.

15. Right-click back on "Local Area Connection" and go to properties again.

16. Go back to the "TCP/IP" settings.

17. This time, select "Obtain an IP address automatically".

18. Hit "Ok".

19. Hit "Ok" again.

20. You now have a new IP address.

Some ISPs do not support this type of procedure and hence there are chances of getting back the same old IP address even after trying
this hack.In this case you need to switch off the modem and then switch it on to get the new IP address.

NOTE: All these tricks works only if you have a dynamic IP address.But if you have a static IP address you have no
option to change your IP.

Windows XP IP Utilities

The following are the IP utilities available in Windows that help in finding out the information about IP Hosts and domains.These are the basic IP Hacking Commands that everyone must know!

NOTE: The term Host used in this article can also be assumed as a Website for simple understanding purpose.

1. PING

PING is a simple application (command) used to determine whether a host is online and available.PING command sends one or more ICMP Echo messages to a specified host requesting a reply.The receiver (Target Host) responds to this ICMP Echo message and returns it back to the sender.This confirms that the Host is online and available.Otherwise the host is said to be unavailable.

Syntax:
C:\>ping gohacking.com

2. TELNET
Telnet command is used to connect to a desired host on a specified port number.For example
Syntax:
C:\>telnet yahoo.com 25
C:\>telnet yahoo.com

NOTE: The default port number is 23.When the port number is not specified the default number is assumed.
Telnet Hacking is explained in detail in the following post.
How To Send Fake Email

3. NSLOOKUP
Many times we think about finding out the IP address of a given site.Say for example google.com,yahoo.com,microsoft.com etc.But how to do this? For this there are some websites that can be used to find out the IP address of a given site.But in Windows we have an inbuilt tool to do this job for us.It is nslookup.Yes this tool can be used for resolving a given domain name into it's IP address (determine the IP of a given site name).Not only this it can also be used for reverse IP lookup.That is if the IP address is given it determines the corresponding domain name for that IP address.

Syntax:
C:\>nslookup google.com

4. NETSTAT

The netstat command can be used to display the current TCP/IP network connections.For example the following netstat command displays all connections and their corresponding listening port numbers.

Eg: C:\>netstat -a

This command can be used to determine the IP address/Host names of all the applications connected to your computer.If a hacker is connected to your system even the hacker's IP is displayed.So the netstat command can be used to get an idea of all the active connections to a given system.

Leave your response!

Hacking Yahoo Messenger

This hacking tutorial will tell you how to hack yahoo messenger while you are engaged in chatting with some person.When you are chatting through yahoo messenger, Yahoo will hide the IP addresses of all the computers that are connected through the yahoo messenger application to the chat room.So it is not possible to find out the IP of the person with whom you are chatting.Then how to get the IP address? Yes it is still possible to hack the IP address during the Yahoo messenger chat.Hacking yahoo messenger is discussed in detail below.

While you are chatting via yahoo messenger the communication between you and the other person takes place indirectly via Yahoo server and not directly.Hence it is not possible to hack his IP address directly.So to hack his IP you must establish a direct communication with him.So,how to do this? It's easy.Just start chatting with some one via Yahoo messenger.During the process of chatting send him a big file.Now the file transfer takes place directly between your computer and the victim's computer(via yahoo messenger application).So now the communication is direct. And you are ready to go. Here's the step-by-step process to hack the messenger and get the IP address of the person .

* Goto the COMMAND PROMPT (START>>>RUN>>>Type CMD).
* Here Type "netstat -n" (without quotes).

NOTE: If you are new to "netstat" and other IP related commands refer this tutorial:Windows XP IP Utilities

* The pic given below shows netstat results of my computer.I was not chatting when i took this pic and hence it looks modified.



* Here local address is your own IP and the foreign address is the IP address of the recipient with whom you are connected via yahoo messenger (There may be multiple recipients and hence multiple foreign addressess).
* Now send him the file.
* Check the output by typing the command "netstat -n" (without quotes).
* Assume the output is something like this.



TCP 127.0.0.10:5101 124.55.23.11:1246 ESTABLISHED

Here 124.55.23.11 is the IP address of the person with whom you are chatting and 1246 is the port number where connection is established.That's It! You have now hacked his IP address.

Once you perfor this hack and get his IP address you can use any of the Remote Administration tools or perform NETBIOS HACKING.Refer this tutorial on Netbios Hacking.

NOTE: Some times there are chances where in the file transfer gets encrypted (takes place via yahoo server itself).So in this case the above hack may fail to work.

Port Scanning

Port Scanning is one of the most popular techniques used by hackers to discover services that can be compromised.

* A potential target computer runs many 'services' that listen at 'well-known' 'ports'.
* By scanning which ports are available on the victim, the hacker finds potential vulnerabilities that can be exploited.
* Scan techniques can be differentiated broadly into Vanilla, Strobe, Stealth, FTP Bounce, Fragmented Packets, Sweep and UDP Scans.

Port Scanning Techniques


Port Scanning Techniques can be broadly classified into:

* Open scan
* Half- open scan
* Stealth scan
* Sweeps
* Misc

Commonly used tools for port scanning

1.Tool: SuperScan 3.0


2. Tool: NMap (Network Mapper)


3. Tool: NetScan Tools Pro 2003

4. Tool: ipEye, IPSecScan
