What are Public IP & Private Ip Addresses.

Internet Protocol (IP) addresses are usually of two types: Public and Private. If you have ever wondered to know what is the difference between a public and a private IP address, then you are at the right place. In this post I will try to explain the difference between a public and a private IP address in layman’s terms so that it becomes simple and easy to understand.
What are Public IP Addresses?
A public IP address is assigned to every computer that connects to the Internet where each IP is unique. Hence there cannot exist two computers with the same public IP address all over the Internet. This addressing scheme makes it possible for the computers to “find each other” online and exchange information. User has no control over the IP address (public) that is assigned to the computer. The public IP address is assigned to the computer by the Internet Service Provider as soon as the computer is connected to the Internet gateway.
A public IP address can be either static or dynamic. A static public IP address does not change and is used primarily for hosting WebPages or services on the Internet. On the other hand a dynamic public IP address is chosen from a pool of available addresses and changes each time one connects to the Internet. Most Internet users will only have a dynamic IP assigned to their computer which goes off when the computer is disconnected from the Internet. Thus when it is re-connected it gets a new IP.
You can check your public IP address by visiting www.whatismyip.com
What are Private IP Addresses?
An IP address is considered private if the IP number falls within one of the IP address ranges reserved for private networks such as a Local Area Network (LAN). The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private networks (local networks):
10.0.0.0 – 10.255.255.255 (Total Addresses: 16,777,216)
172.16.0.0 – 172.31.255.255 (Total Addresses: 1,048,576)
192.168.0.0 – 192.168.255.255 (Total Addresses: 65,536)
Private IP addresses are used for numbering the computers in a private network including home, school and business LANs in airports and hotels which makes it possible for the computers in the network to communicate with each other. Say for example, if a network X consists of 10 computers each of them can be given an IP starting from 192.168.1.1 to 192.168.1.10. Unlike the public IP, the administrator of the private network is free to assign an IP address of his own choice (provided the IP number falls in the private IP address range as mentioned above).
Devices with private IP addresses cannot connect directly to the Internet. Likewise, computers outside the local network cannot connect directly to a device with a private IP. It is possible to interconnect two private networks with the help of a router or a similar device that supports Network Address Translation.
If the private network is connected to the Internet (through an Internet connection via ISP) then each computer will have a private IP as well as a public IP. Private IP is used for communication within the network where as the public IP is used for communication over the Internet. Most Internet users with a DSL/ADSL connection will have both a private as well as a public IP.
You can know your private IP by typing ipconfig command in the command prompt. The number that you see against “IPV4 Address:” is your private IP which in most cases will be 192.168.1.1 or 192.168.1.2. Unlike the public IP, private IP addresses are always static in nature.
Unlike what most people assume, a private IP is neither the one which is impossible to trace (just like the private telephone number) nor the one reserved for stealth Internet usage. In reality there is no public IP address that is impossible to trace since the protocol itself is designed for transperancy.

Enable Disable USB Ports

How to disable or enable USB port or device

USB Devices are portable enough to carry the data from one computer to another , It is always risky to enable USB ports of computers in large organizations , data center and cyber cafes since it can be the gateway for virus and malwares. You can disable or enable USB port or device in three ways
Enable / Disable USB port and device in BIOS
It can be enabled or disabled in BIOS where the peripheral device setting is configured. While booting the system you will be getting an option to configure BIOS settings. But only problem is you will not be able to use those USB ports for any purpose like connecting USB keyboards or mouse or any devices.
Enable / Disable USB port and device using registry hack in windows
Another effective way to enable or disable USB port or device is to hack registry entry in windows , it will allow you to use your USB port for other functions like connecting keyboard or mouse but you can restrict the data storage through USB port
A. Click on Start –> Run –> regedit [enter]
B. Search for the key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor”
C. Select the key UsbStor, double clicks on Start value.
D. In “Value data” enter 4 to disable USB storage, or enter 3 to enable USB storage on windows system


Freeware to enable or disable USB port or device in Windows 7 and XP
There is a nice tool to enable or disable USB PORT in registry. It exactly does the above mentioned steps. If you are not an experienced users then I would prefer you to use below mentioned software for this task. Please remember that it is always risky to edit windows registry.

Leet Language for h4x0rs....

“h4x0r 1n m3″ – Speaking Leet : Language of Hackers

Share

Leet, the language of the Geeks and Hackers.
To speak leet, you more or less need to un-learn proper english. The history of leet goes back to the early days of online message boards, or forums, where users can post messages to carry on a threaded conversation. In an attempt to “Clean-Up” the language that users would sometimes post, admins added a filtering system to the message board which would replace restricted words with some type of alternative.
For example, the word “crap” might become “crud.” It didn’t take people long to figure out that you could get around this filter simply by altering the original word somehow, like changing “crap” to “c-r-a-p” or “krap” or “crrrap.” it was soon obvious that these filtering systems could never possibly cover every variation because people would just keep inventing new ones, and so leet was born.

In the most generic explanation, leet is merely replacing certain letters of the alphabet with numbers that bear a slight resemblance. l becomes 1, e becomes 3, t becomes 7, and so on… leet becomes 1337.
In a not so generic explanation, leet is also a play on words. The word leet itself is actually a shorter, easier way of saying the word “elite” which the dictionary defines as: the best or most skilled members of a group.
An odd thing about the internet is that when certain trends catch on, they seem to spread on a massive scale. Leet is one of those trends that just wouldn’t die; instead it grew and is still growing to this very day. Another popular trend to spread was aybabtu (all your base are belong to us) which is just one horribly translated line out of many from the video game “Zero Wing.” Then there was “Star Wars Kid” where a home video of some kid swinging a pole around was uploaded to the internet and altered to make it look like he was swinging a light saber. Nobody knows why these things spread like plagues but they each share a unique taste in humor. Anyway, back on topic, Every True Hacker Knows Leet.
Given below is a simple translation table to cover some common transitions and words. Please bear in mind that the syntax may vary:

A = @ B = |3 C = ( D = |) E = 3 F = |= G = 6 H = |-| I = | J = _| K = |( L = |_ M = /\/\ N = /\/ O = 0 P = |* Q = 0, R = |2 S = $ T = 7 U = |_| V = \/ W = \/\/ X = )( Y = ‘/ Z = 2

a = 4 b = 8 c = © d = |> e = 3 f = # g = 9 h = h i = | j = j k = |< l = 1 m = m n = n p = |* q = 0. r = ® s = 5 t = + u = 00 v = \/ w = \/\/ x = >< y = j z = 2

at = @ ck = x0r the = teh you = j00 or u own = pwn ck = x0r programs = progz god = r00t fool = f00 heart/love = <3 what’s up = sup that = dat look at = peep kill = frag sweet = schweet sleep = reboot greater than = > newbie = n00b no = noes woo hoo = w00t why = y be = b are = r dude = d00d fear = ph34r and = & super = uber

blah/me = meh yo = j0 rock = r0xx0r hacker = h4x0r cool = k3wl software = warez computer = pu73r chick = chix0r good = teh win bad = teh lose loser = l4m3r aol = uh, 14m3r money = monies bye = bai kick = punt porn = pr0n skill = m4d 5killz hello = ping robot = b0t naked = n3k3d what = wut whatever = wutev cool = c00 to/two = 2 with = wit sex = cyb3r

As you can see there is a lot of slang involved, some of which you might even be familiar with. Aside from normal words, leet branches out to acronyms as well. lol (laughing out loud) becomes lawlz, rofl (rolling on floor laughing) becomes roffle, roflmao (rolling on floor laughing my arse off) becomes roffle-mayo. If you haven’t guessed it yet, leet is a complete mockery of the english language.
Typos are encouraged; in fact, an urban legend floating around the internet states that it deosn’t mttaer waht oredr the lteters in a wrod are, so lnog as teh frist and lsat ltteer are at teh crroect pclae. teh rset can be a taotl mses and yuo can uslauly siltl raed it wothuit any porbelm. of course, if you experiment with that you’ll soon find that it isn’t always true, but still interesting.
Note: Typing in various caps and multicolored text is not 1337.
Just because you know how to speak leet is no excuse to speak it all of the damn time. It is funny when used appropriately, but otherwise completely annoying. Leet should only be used when you’re feeling powerful and/or energetic. There are also many different flavors of leet: it can be used lightly (a few leet characters), or heavily (practically all leet characters).
Let’s practice a few leet sentences:
English: i didn’t really care for that movie.
Leet: dat dot mov wuz teh lose!
English: wow, i won.
Leet: omgz (oh my godz) lolz!! i pwned j00r @$$!
English: i am learning how to become an elite hacker.
Leet: i 4/\/\ 134|2/\/i/\/9 |-|0\/\/ 2 83c0m3 4 1337 h4x0r, roffle-mayo.
English: sigh, what in the world is that supposed to be?
Leet: *sighs* wtf (what the f—) b dat f00?
English: i’m tired.
Leet: i’m 80u7 2 m4k3 1ik3 ie (internet explorer) & cr45h. /m3h y4wn5
Hopefully you’ve got a pretty good idea by now of how leet is used; it’s not an entirely complex language. As with any language, the more you’re subjected to it the more it will sink in.

Google Search Tricks:
Well let me tell You what actually google tricks mean. Google tricks/google tips, does not mean hacking google, Using the below Google operators, we can get the desired google result very quickly. Well we can name this as hidden google secrets or Advanced google searching. .

password hacking Techiques

Different ways of password cracking .

Share

Password cracking is the process of recovering secret passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password.
Most passwords can be cracked by using following techniques :
1) Hashing :-
Here we will refer to the one way function (which may be either an encryption function or cryptographic hash) employed as a hash and its output as a hashed password.
If a system uses a reversible function to obscure stored passwords, exploiting that weakness can recover even ‘well-chosen’ passwords.
One example is the LM hash that Microsoft Windows uses by default to store user passwords that are less than 15 characters in length.
LM hash breaks the password into two 7-character fields which are then hashed separately, allowing each half to be attacked separately.
Hash functions like SHA-512, SHA-1, and MD5 are considered impossible to invert when used correctly.
2) Guessing :-
Many passwords can be guessed either by humans or by sophisticated cracking programs armed with dictionaries (dictionary based) and the user’s personal information.
Not surprisingly, many users choose weak passwords, usually one related to themselves in some way. Repeated research over some 40 years has demonstrated that around 40% of user-chosen passwords are readily guessable by programs. Examples of insecure choices include:
* blank (none)
* the word “password”, “passcode”, “admin” and their derivatives
* the user’s name or login name
* the name of their significant other or another person (loved one)
* their birthplace or date of birth
* a pet’s name
* a dictionary word in any language
* automobile licence plate number
* a row of letters from a standard keyboard layout (eg, the qwerty keyboard — qwerty itself, asdf, or qwertyuiop)
* a simple modification of one of the preceding, such as suffixing a digit or reversing the order of the letters.
and so on….
In one survery of MySpace passwords which had been phished, 3.8 percent of passwords were a single word found in a dictionary, and another 12 percent were a word plus a final digit; two-thirds of the time that digit was.
A password containing both uppercase & lowercase characters, numbers and special characters too; is a strong password and can never be guessed.
Check Your Password Strength
3) Default Passwords :-
A moderately high number of local and online applications have inbuilt default passwords that have been configured by programmers during development stages of software. There are lots of applications running on the internet on which default passwords are enabled. So, it is quite easy for an attacker to enter default password and gain access to sensitive information. A list containing default passwords of some of the most popular applications is available on the internet.
Always disable or change the applications’ (both online and offline) default username-password pairs.
4) Brute Force :-
If all other techniques failed, then attackers uses brute force password cracking technique. Here an automatic tool is used which tries all possible combinations of available keys on the keyboard. As soon as correct password is reached it displays on the screen.This techniques takes extremely long time to complete, but password will surely cracked.
Long is the password, large is the time taken to brute force it.
5) Phishing :-
This is the most effective and easily executable password cracking technique which is generally used to crack the passwords of e-mail accounts, and all those accounts where secret information or sensitive personal information is stored by user such as social networking websites, matrimonial websites, etc.
Phishing is a technique in which the attacker creates the fake login screen and send it to the victim, hoping that the victim gets fooled into entering the account username and password. As soon as victim click on “enter” or “login” login button this information reaches to the attacker using scripts or online form processors while the user(victim) is redirected to home page of e-mail service provider.
Never give reply to the messages which are demanding for your username-password, urging to be e-mail service provider.
It is possible to try to obtain the passwords through other different methods, such as social engineering, wiretapping, keystroke logging, login spoofing, dumpster diving, phishing, shoulder surfing, timing attack, acoustic cryptanalysis, using a Trojan Horse or virus, identity management system attacks (such as abuse of Self-service password reset) and compromising host security.
However, cracking usually designates a guessing attack.

IP ADDRESS

Have You Ever Tought with an IP address. You can Do Many of great things.

The IP address is stands for internet Protocol every computer which is connected to internet have its own ip address.
Which an IP address we Can track the location. of the user i.e. from where He Is calling from or the location of the user

Some Facts About IP Address:

• Every Device Connected to Network that may be Printer, Scanner , or any server computer or Client computer all uses its own ip address.
• We can assume IP address as its Mobile Number by which we can call or manage that device
• IP addresses are, but they are usually stored in text files and displayed in human-readable notations, such as 172.16.254.1 (for IPv4), and 2001:db8:0:1234:0:567:8:1 (for IPv6).
• There are Two Versions of IP address IPV4 and IPv6.
• The IPV4 address is of 32 bits.

• The IPV6 address is of 32 to 128 bits. long

Assigning IP address:

• There are 2 ways by which IP address can be assigned
• Static and Dynamic way
• Static IP addresses are manually assigned to a computer by an administrator.

• Dynamic IP addresses are most frequently assigned on LANs and broadband networks by  Dynamic Host Configuration Protocol (DHCP) servers. 

Tools For Assigning IP Address :

• The UNIX Type OS are Best for managing  IP address
• Some Commands for IP Address are:
• ipconfig ( for knowing ip address)
• ipconfig /all ( for knowing all ports devices ip address)
• netsh
• netstat   ( for knowing from where to where data is transmitting)
• route
• lanstat
• ifstat
• iproute2
•  

These are some utilites commands for managing ip address:
Windows users can use it into command promt
and Unix users can use it in Terminal
