External IP and Internal IP

Sorry guys..i was too bsy with ma studies....so jst cant concentrate on my blog.....but from now on i hope it will work regularly.....ok lets move into todays topic
There are a couple of concepts you need to know before you can understand port forwarding. I'm going to make a couple broad statements that are almost always true. For simplicity lets assume they are true for now.
1.) Every device on the internet has at least one ip address. The IP address is a number that is used to identify a device. For more information on ip addresses refer to our What is an IP Address page.
2.) Every IP address is divided up into many ports. When one computer sends data to another computer, it sends it from a port on an ip address to a port on an ip address. For more information on ports refer to our What is a Port page.
3.) A port can only be used by one program at a time.
Now that we've got those general concepts out of the way let's talk about NAT. NAT is an acronym for Network Address Translation. NAT takes one ip address and basically breaks it into many ip addresses.

Here the external ip address is broken into two internal ip addresses. The first ip address "IP Address1" is the gateway. While "IP Address2" is the ip address of the first computer. Take note that the router has two ip addresses. It has the external ip address, and an internal ip address which acts as the gateway for every computer on the network.

Excuse my rough drawing. Computers on the internal network can only "see" internal ip addresses. So computers on the internal network can not send data directly to a computer outside of the network. When a computer on the network wants to send data to a computer outside of the network, it sends the data to the gateway. Remember the gateway is the internal ip address of the router. The router then takes this data and sends it out to the computer on the internet. The router sends the data out of the external ip address. The same thing is true of computers on the internet. A computer outside of the network can not "see" a computer inside of the network. They can only "see" and send data to the external ip address of the router. The router must then decide what to do with this data. Lucky for us NAT takes care of most of the work for us. There are some programs that NAT was not designed to work with, those are the programs we need to set up port forwarding for. Okay take a deep breath! We are on to port forwarding.
Now that you understand the general concepts of a network, explaining port forwarding is easy. When a computer on the internet sends data to the external ip address of the router, the router needs to know what to do with the data. Port Forwarding simply tells the router which computer on the local area network to send the data to. When you have port forwarding rules set up, your router takes the data off of the external ip address:port number and sends that data to an internal ip address:port number. Port Forwarding rules are created per port. So a rule set up for port 53 will only work for port 53.
A port can only be used by one program at a time! Think of how this rule interacts with NAT. Well you've only got one external ip address on your router. When computer 1 is using port 500, it is using port 500 on it's internal ip address. If you have set up a port forwarding rule for computer 1 and port 500, the external ip address's port 500 is also in use. This means that you can only use port 500 on one computer on the network at a time. Using port 500 on two computers at the same time would violate the one program rule, and your data would get messed up. Most routers require you to specify an internal ip address to forward ports to, just for this reason. Some do not, so be aware of this. Port Forwarding rules will only work for one computer at a time!

'Innobuzz' CISE DLP - Honest Review by Cyber Hoodies

Hello Friends,
 

Today is about an exciting post.... yeah, that's 'Innobuzz', the largest and prestigious institute of Ethical Hacking and Cyber Security studies in India. You might have heard about this institute many times before but still some of you may not know how imperative it is for you if you are in ethical hacking field. I know many of you can "HACK". But you must agree that 'Hacking' cannot be taught. It's comes from within, the skill comes from within. But one hacker should must know the every rooms of network, you should learn every aspect of Internet that how does it work, If you know how Internet works only then you will able to maintain their security and even can break into the security. but it requires knowledge of network, it requires the knowledge of executing procedures and using the tools and scripts.So you must need to study for that. I know many of you are very keen to know what the Hack is.How does it work , how hackers break into computers and get access of a computer with out having the legal permission. That's very interesting and even fun for a hacker.

Hacking WEP wifi passwords Basic Entry into a WEP Encrypted Network


This Tutorial explains EVERYTHING in detail So, it is quite long. Enjoy.


1. Getting the right tools
This Tutorial is in Backtrack 3.But you can Download The Backtrack 4.


Download Backtrack 4. It can be found here:
http://www.backtrack-linux.org/downloads/

I downloaded the Dvd iso and burned it to a Dvd. Insert your BT4 Dvd/usb drive and reboot your computer into BT4. I always load into the 3rd boot option from the boot menu. (VESA/KDE) You only have a few seconds before it auto-boots into the 1st option so be ready. The 1st option boots too slowly or not at all so always boot from the 2nd or 3rd. Experiment to see what works best for you.


2. Preparing the slave network for attack


Once in BT4, click the tiny black box in the lower left corner to load up a "Konsole" window. Now we must prep your wireless card.
Type:


airmon-ng


You will see the name of your wireless card. (mine is named "ath0") From here on out, replace "ath0" with the name of your card.
Now type:


airmon-ng stop ath0


then type:ifconfig wifi0 down


then:


macchanger --mac 00:11:22:33:44:55 wifi0


then:


airmon-ng start wifi0


What these steps did was to spoof (fake) your mac address so that JUST IN CASE your computeris discovered by someone as you are breaking in, they will not see your REAL mac address. Moving on...
Now it's time to discover some networks to break into.


Type:


airodump-ng ath0


Now you will see a list of wireless networks start to populate. Some will have a better signal than others and it is a good idea to pick one that has a decent signal otherwise it will take forever to crack or you may not be able to crack it at all.
Once you see the network that you want to

crack, do this:


hold down ctrl and type c


This will stop airodump from populating networks and will freeze the screen so that you can see the info that you need.


**Now from here on out, when I tell you to type a command, you need to replace whatever is in parenthesis with what I tell you to from your screen. For example: if i say to type:
-c (channel)
then dont actually type in
-c (channel)
Instead, replace that with whatever the channel number is...so, for example you would type:
-c 6
Can't be much clearer than that...lets continue...


Now find the network that you want to crack and MAKE SURE that it says the encryption for that network is WEP. If it says WPA or any variation of WPA then move on...you can still crack WPA with backtrack and some other tools but it is a whole other ball game and you need to master WEP first.

Once you've decided on a network, take note of its channel number and bssid. The bssid will look something like this --> 05:gk:30:fo:s9:2n
The Channel number will be under a heading that says "CH".
Now, in the same Konsole window, type:


airodump-ng -c (channel) -w (file name) --bssid (bssid) ath0


the FILE NAME can be whatever you want. This is simply the place that airodump is going to store the packets of info that you receive to later crack. You don't even put in an extension...just pick a random word that you will remember. I usually make mine "wepkey" because I can always remember it.


**Side Note: if you crack more than one network in the same session, you must have different file names for each one or it won't work. I usually just name them wepkey1, wepkey2, etc.


Once you typed in that last command, the screen of airodump will change and start to show your computer gathering packets. You will also see a heading marked "IV" with a number underneath it. This stands for "Initialization Vector" but in noob terms all this means is "packets of info that contain clues to the password." Once you gain a minimum of 5,000 of these IV's, you can try to crack the password. I've cracked some right at 5,000 and others have taken over 60,000. It just depends on how long and difficult they made the password.


Now you are thinking, "I'm screwed because my IV's are going up really slowly." Well, don't worry, now we are going to trick the router into giving us HUNDREDS of IV's per second.


3. Actually cracking the WEP password


Now leave this Konsole window up and running and open up a 2nd Konsole window. In this one type:


aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 ath0




This will send some commands to the router that basically cause it to associate with your computer even though you are not officially connected with the password. If this command is successful, you should see about 4 lines of text print out with the last one saying something similar to "Association Successful :-)" If this happens, then good! You are almost there. Now type:


aireplay-ng -3 -b (bssid) -h 00:11:22:33:44:55 ath0




This will generate a bunch of text and then you will see a line where your computer is gathering a bunch of packets and waiting on ARP and ACK. Don't worry about what these mean...just know that these are your meal tickets. Now you just sit and wait. Once your computer finally gathers an ARP request, it will send it back to the router and begin to generate hundreds of ARP and ACK per second. Sometimes this starts to happen within seconds...sometimes you have to wait up to a few minutes. Just be patient. When it finally does happen, switch back to your first Konsole window and you should see the number underneath the IV starting to rise rapidly. This is great! It means you are almost finished! When this number reaches AT LEAST 5,000 then you can start your password crack. It will probably take more than this but I always start my password cracking at 5,000 just in case they have a really weak password.


Now you need to open up a 3rd and final Konsole window. This will be where we actually crack the password. Type:


aircrack-ng -b (bssid) (filename)-01.cap


Remember the filename you made up earlier? Mine was "wepkey". Don't put a space in between it and -01.cap here. Type it as you see it. So for me, I would type wepkey-01.cap
Once you have done this you will see aircrack fire up and begin to crack the password. typically you have to wait for more like 10,000 to 20,000 IV's before it will crack. If this is the case, aircrack will test what you've got so far and then it will say something like "not enough IV's. Retry at 10,000." DON'T DO ANYTHING! It will stay running...it is just letting you know that it is on pause until more IV's are gathered. Once you pass the 10,000 mark it will automatically fire up again and try to crack it. If this fails it will say "not enough IV's. Retry at 15,000." and so on until it finally gets it.




If you do everything correctly up to this point, before too long you will have the password! now if the password looks goofy, dont worry, it will still work. some passwords are saved in ASCII format, in which case, aircrack will show you exactly what characters they typed in for their password. Sometimes, though, the password is saved in HEX format in which case the computer will show you the HEX encryption of the password. It doesn't matter either way, because you can type in either one and it will connect you to the network.


Take note, though, that the password will always be displayed in aircrack with a colon after every 2 characters. So for instance if the password was "secret", it would be displayed as:
se:cr:et
This would obviously be the ASCII format. If it was a HEX encrypted password that was something like "0FKW9427VF" then it would still display as:
0F:KW:94:27:VF
Just omit the colons from the password, boot back into whatever operating system you use, try to connect to the network and type in the password without the colons and presto! You are in!


It may seem like a lot to deal with if you have never done it, but after a few successful attempts, you will get very quick with it. If I am near a WEP encrypted router with a good signal, I can often crack the password in just a couple of minutes.


I am not responsible for what you do with this information. Any malicious/illegal activity that you do, falls completely on you because...technically...this is just for you to test the security of your own network. :-)


I will gladly answer any legitimate questions anyone has to the best of my ability.
HOWEVER, I WILL NOT ANSWER ANYONE THAT IS TOO LAZY TO READ THE WHOLE TUT AND JUST ASKS ME SOME QUESTION THAT I CLEARLY ANSWERED. No one wants to hold your hand through this...read the tut and go experiment until you get it right.


There are rare occasions where someone will use WEP encryption with SKA as well. (Shared Key Authentication) If this is the case, additional steps are needed to associate with the router and therefore, the steps I lined out here will not work. I've only seen this once or twice, though, so you probably won't run into it. If I get motivated, I may throw up a tut on how to crack this in the future.



Thanks for Reading. plz do comment..........

Evolution and Future of Personal Computing

Let’s talk about last two decades in terms of evolution of personal computing.

1991-2000: Some major hardware developments occurred, which made the dream of personal computing come true. Software giants like Microsoft, Apple, Google, etc evolved and took over the IBM-dominant market. Desktops started making their way into offices and eventually, homes.

2001-2010: The starting of decade was taken over by Microsoft operating system, Windows XP. It spread like a fire, used in most offices, homes, business etc.                                                           Apple developed some products like iMac, MacBook, which had its different customer base, not as vast as Microsoft. But the end brought increment in the number of Mac users. 

On the hardware end, a vast change could be seen throughout. Huge, bulky desktops started shrinking and soon laptops became the first choice of home users. Apple, always known for its innovations, took the world by surprise on its launch of MacBook air. It was the thinnest laptop on the planet and was ultra portable. By the end, apple again came with the one of the biggest innovations of the decade, which might change computing forever. It was its tablet PC, iPad. Soon, many companies started launching their own android tablets, but still the iPad dominates the tablet market, mainly because it’s smooth, fluid interface and its large iOS app base. Microsoft, revealed its plans and preview of Windows 8, which was optimized both for tablet use and desktop/laptop use.
