Viewing Leftover Driver Entries

Windows keeps a Device Manager entry for every piece of
hardware that's ever been recognized by the system, regardless
of whether it is currently present in the machine or was even
set up correctly in the first place. The "View Hidden Devices"
option in Device Manager won't show you these "residual"
drivers. You can force it to show you everything by going to
My Computer Properties, the Advanced tab, Environment
Variables, and adding a new system variable with the name
"DEVMGR_SHOW_NONPRESENT_DEVICES" and a value of 1. Now opening
Device Manager and choosing "Show Hidden Devices" really will
show you everything. Standard practice at the factory is to
use a single image and just move it from model to model,
letting it plug and play all the new hardware along the way.
This leaves you with an impressive list of hardware still in
the Device Manager, but no longer in the system. You also see
this to a lesser degree when you restore a system from an
image you created for backup purposes. These "residual"
drivers can sometimes cause all kinds of weirdness and are
best removed by right-clicking on their entry in the Device
Manager and choosing "uninstall".

This works on Windows 2000/XP (and I assume Server 2003,
though I haven't tried it). Anyone running a factory loaded
Compaq or Dell will be amazed at the amount of junk left over
from this process.

Thanks, Jon. Indeed, Windows has a thing about hanging on to ghost
entries in Device Manager and also in the Registry. (This is one of the
reasons why Registries inflate so much over time.) A little judicious
ghostbusting lets your PC run cleaner and leaner!

Stop A Restart Process In 3steps

Stop A Restart Process In 3steps

Some times we need to stop some restart process quickly. In windows XP some times it gives auto restart warning and here is good solution for it.

1. Go to Start menu
2. Click on RUN
3. Enter the following command excluding hashcodes "shutdown -a"

its Done.

Steps to Clean Install XP

Steps to Clean Install XP

If the above instructions for configuring your system to boot from CD
or you have acquired the necessary boot floppy/floppies; you can now
boot the computer and follow the on screen prompts. Have your Product Key
available, typical install is around 30 minutes. If setup seems to hang,
wait at least 10 minutes + before restarting system. You should experience
momentary screen blackouts.

1. Power on the computer. Press the Pause/Break key as soon as you see
text on the screen. [If you currently are running in an OS of any flavor,
insert XP CD and restart computer. Skip to #3 if system is configured
to boot from CD.]


2. Insert XP CD into CD drive. Press ENTER to resume booting from the XP CD.  
(BIOS must support booting from CD and boot order must be set so CD
boots before hard drive. If computer does not support booting from CD
go to 2a for floppy install).

2a. Floppy install: Boot from Win98/Me/Special XP install floppy
disk with smartdrv.exe added to the boot disk; or the Win XP set
of 6 floppy disks.

3. Look for message "booting from CD" usually located at the bottom of
the screen. If you have a factory splash screen, press ESC to unload
it.

3a. Floppy install: From the A Prompt; A:\type: smartdrv.exe. then
press ENTER. If you are using the XP boot floppy setup disks skip
to step #5.

4. Press any Key when you see the prompt to "Press Any Key"

4a. Floppy install: CD to the location of the CD-ROM drive with the
XP setup files; CD to the i386 folder where you will type: winnt.exe
to start setup.

5. Setup will start copying files, if you need to install any third
- party or RAID drivers press F6 at this time. the copying of files
can take awhile.

6. Next you will get the option to repair or enter setup, choose to
enter setup. Press ENTER. To see images full size, place mouse cursor
over image and click/double click or press the left button and open.

7. Press F8 if you agree to the license.

8. Setup will scan for previous Windows installations

9. If you are using the upgrade version of XP on a computer without
any version of Windows currently installed, this is where you will
replace the XP CD with your qualifying CD, XP setup will scan the
qualifying CD and instruct you to replace it with the XP CD to continue
XP setup; otherwise, you will not see this screen. Clean install
qualifying media can be any of the following Win NT3.51, 4.0, 2000,
Win 95, 98, Me. 10. Choose the location to install.

10a If this is a clean hard drive, you can choose to create a
partition in the un-partitioned space. At this point, you can allow
Setup to use all the space or set a size for the partition.

10b If the hard drive or partition has a previous installation of
XP you want to remove, choose to delete the partition by pressing
"D". You will then be prompted to create a new partition in the
empty space. This will remove all data from the delete space.

10c If you intend to use multiple partitions, or dual boot, this is
where you specify the size of the boot partition and or setup
location for XP. If you are planning to dual boot XP, I would
create a small 100 meg DOS partition for the first primary partition,
then an 8 to 10 gig partition for XP. You can partition and format
the remaining space after XP is setup from Disk Manager. If you do not
intend to dual boot, you can either use all the un-partitioned space,
or create an 8 to 10 gig partition for XP and leave the rest free to
partition later.

Note: If a fat32 partition larger than 32 gigabyte is desired, the
hard drive or partition will need to be created before running XP
setup. XP will not create a fat 32 partition larger than 32 gig, but
will support one previously created.

11. Choose the file system from this screen. If dual booting and you
created the small 100 meg partition, make it a fat partition. NTFS is
configured at the optimal file size during the initial setup. See this
link for more on NTFS

12. If you have more that one partition or hard drive on your system,
make sure you are formatting the correct partition/drive.

13. Select F to continue.

14. Setup will show a progress box and reboot when copying files is
complete.

15. When you see the "Press any Key to Reboot" do not Press any Key.
If CD boots anyway, remove CD and reboot.

16. From this point, you will follow the on screen prompts.

17. If you live outside the US, you will probably need to modify the
default settings.

18. Personalize your XP Enter your Name and Organization.

19. Enter the Product Key. The Key is located on the back of the CD folder
in the Retail versions, and on a holographic label with the OEM
versions purchased with a piece of hardware. Write this key down and
secure it in a safe place in case the original is misplaced destroyed
through natural causes or stupidity. 8-)

20. Choose a name for the computer, this should be a unique name for
the computer, especially if it is to be connected to a network. In Pro,
you are given the option of creating a password or leaving it blank.

21. Set your Time Zone and Time and Date.

22. Setup will scan for network.

23. If detected you will have the choice to choose a typical
configuration or custom. Choose typical if you are unsure.

24. For home you will choose your workgroup, if a network is already
established and you intend to connect to it, use the existing
workgroup name, otherwise, I suggest using the default.

25. For Pro, the same goes for Pro as suggested for Home, but you will
have the choice to join a Domain, if you do not have a Domain or do
not know leave blank.

26. Setup will continue and reboot when completed ignore the "Press
Any Key".

27. The loading XP window will now display after reboot.

28. You will see a change display settings, say yes, and accept the
setting if you can see the screen after accepting.

29. You will see a welcome screen, press next and unfortunately you
have to wait for the dialog to finish.

30. Set up you internet or network connection.

31. This is the Activate, Register screen. You must activate within
30 days of installing XP, but you do not ever have to register,
Registration is completely optional and if you do not register, no
personal information will be transmitted during activation. If you
register, then activation will transmit that information along with
the activation. The first Activation is usually done over the internet
if the computer is connected to the internet, otherwise, it can be
accomplished by copying the alphanumeric string from the activation
screen and make a phone call to the on screen supplied phone number.
The activation center will then give you a slightly longer number to
input into for activation. I suggest you do not activate immediately
in case you need to make hard ware changes, or install to a different
system within the thirty days, and you will be reminded on boot up
until you do.

Blaster worm warning: Do not immediately activate over the internet
when asked, enable the XP firewall before connecting to the internet.
You can activate after the firewall is enabled.
Control Panel - Network Connections. Right click the connection you
use, Properties, and there is a check box on the Advanced page.

32. Setup users screen. Set at least one user for yourself or the person
that will be using the computer.

33. Thank You

34. Logon to XP and apply Service Pack and Critical updates from Windows
Update before installing any software or hardware.

35. Install your anti-virus software.

36. Install all applications and setup your email.

37. Restore from Files and Settings transfer after reinstalling all
applications.

Some Google Tricks, again

A few things you might want to try with Google:

Hand type the following prefixes and note their utility:

link:url Shows other pages with links to that url.

related:url same as "what's related" on serps.

site:domain restricts search results to the given domain.

allinurl: shows only pages with all terms in the url.

inurl: like allinurl, but only for the next query word.

allintitle: shows only results with terms in title.

intitle: similar to allintitle, but only for the next word. "intitle:webmasterworld google" finds only pages with webmasterworld in the title, and google anywhere on the page.

cache:url will show the Google version of the passed url.

info:url will show a page containing links to related searches, backlinks, and pages containing the url. This is the same as typing the url into the search box.

spell: will spell check your query and search for it.

stocks: will lookup the search query in a stock index.

filetype: will restrict searches to that filetype. "-filetype:doc" to remove Microsoft word files.

daterange: is supported in Julian date format only. 2452384 is an example of a Julian date.

maps: If you enter a street address, a link to Yahoo Maps and to MapBlast will be presented.

phone: enter anything that looks like a phone number to have a name and address displayed. Same is true for something that looks like an address (include a name and zip code)

site:www.somesite.net "+www.somesite.+net"
(tells you how many pages of your site are indexed by google)

allintext: searches only within text of pages, but not in the links or page title

allinlinks: searches only within links, not text or title


I hope there is something new in here for you and maybe this infos will be helpfull for ya.

The Ultimate Guide To Installing Windows Xp Sp2

First things first,

The warez keys that allow you to install XP SP2 are ones with the the PID (Product ID) of xxxxx-640-xxxxxxx-xxxxx

(Note: x's will be numbers)

the easiest way to check yours is by pressing the Windows Key + Break.

In the System Properties window that appears look down to the Registered to: section, if the second group of 3 numbers reads anything other than 640 you need this guide. If it reads 640 then you are safe.


How to change your Product Key

Stage 1: Choose your Product Key

* Download the XPSP2-Keygen pack and extract its contents to a folder of your choice
* Open up XPSP2 & Office KeyGen.exe and change the Windows version to Windows XP Pro. VLK (You will notice the product ID range change to 640)
* Hit Generate a few times to generate your valid keys.
* Make a note of the key you have chosen.


Stage 2: Validate your Product Key

* Open up The Blue Lists XPKey.exe and choose the following options:
Software: Windows XP Corp
Mode: Test Key
* In the Progress box enter your key in the spaces provided
* Hit the Process! button. A small box will appear telling you if your key is valid or invalid. If valid move onto the final stage of actually changing the key, if not, please try again


Stage 3: Changing the Product Key

* Open up XPProCorp-keyChanger.exe and hit space to continue, you will see a huge list of keys appear, totally disregard them, hit space again.
* When the Activate Windows box appears choose the 2nd option 'Yes, I want to telephone a customer service representative to activate Windows' and click Next
* In the next window (Activate Windows by phone) choose the option 'Change Product Key' which is across the bottom
* On the Change product key screen enter in your valid XPSP2 Product Key and click Update
* Once you return to the Activate Windows by phone screen simply close the Activate Windows box.
* Press the Windows Key + Break to confirm you have the correct PID. If it reads xxxxx-640-xxxxxxx-xxxxx, congrats you can safely install XP SP2

The Modern Phreakers Guide To Beige Boxing

The Modern Phreakers Guide To Beige Boxing

*Note: If this version is fucked because of the text then goto

sorry about the faults.

Introduction://
Well as the title states this is the “Modern Phreakers Guide To Beige Boxing”.
Most people think phreaking is a dead art, but a few boxes remain. The Beige Box,
also known as the Lineman’s Handset, is alive and kicking. What the beige box does
is lets you “jack” into another person’s phone from outside their house. This can be
very useful for prank calls, tapping a phone line, long distance that you don’t want
to pay for, and connecting to the internet through 56k for those extremely sensitive
hacks.

Parts://
Interested so far? Ok well this is all you will need:
1. A crappy ass phone that you wont miss (As small as possible)
2. Wire clippers
3. Wire Strippers
4. Alligator Clips
5. Tape

Most of these are common things you can find or steal from your dad. RadioSlut
(radio shack) carries alligator clips and so do hardware stores.

Construction://
I’m gone go describe the way the wires are arranged inside a telephone line that
runs from your phone to the jack in the wall so there will be no confusion *cough*
CYRUS *cough*. I will break it up into 3 stages.

Stage 1: Outer Casing...... The un-touched phone line
Stage 2: Inner Wires....... This contains 4 wires (or two if you have a gay phone like me)
Stage 3: Exposed Wire...... The actual exposed wires.

Ok now take the outer casing and cut all the way through the wire right before the
male plug (the part that goes into the jack in your wall). Then take your wire
strippers and strip that wire back 5 inches so you can see the other four wires.
Clip the two wires on both sides (unless you only have two) so the two inner wires
are the only ones left. Then strip the two inner wires about half an inch so you have
fully exposed the wire. Now you take your alligator clips and attach one to each wire,
making sure the wire is up inside the clip good and the exposed wire is touching the
metal on the clip. Tape the wire down good so it won’t move or come out and BOOM you
have just completed your first beige box.

How To Use://
Well here is the fun part; usage of your newly built Beige Box. What you are looking
for is a box outside the house that all the phone lines run to. It should be about
10”x10” and were I live you need a screw driver to get into it. Once you have found
it you should see a bunch of wires running to four round things that are positioned
like so:



O O

O O


Ok now take your alligator clips and put them on the two bottom ones or the two top
ones, either way it should work, now pick up your box and you should hear a dial tone,
dial out like you normally would.

Different Uses://
Hmmm well if you haven’t figured out what you’re gonna use this for then why are you
building it? Maybe you want to call your online girlfriend long distance, maybe you
want to harass the operator for fun, maybe you want free phone sex, or maybe you
wanna hook up your laptop and dial out. All this can be accomplished by using the
beige box. But I warn you, if someone picks up on the line and hears you talking they
are going to get suspicious, so don’t call someone who will rat on you or say your
name while using it.

Other Ways of Beige Boxing://
Yes there are other ways, and some are extremely nifty. Some modern terminals (Things
outside the house) have jacks so you don’t need to build one, just take a regular
phone and plug it in like you normally would, but that disables your ability to
listen or fuck with the person talking so I don’t use this method. Another way is
take your beige box to a COCOT pay phone and either follow the wires that run from
the phone till you can expose them or cut the wire on the handset at the actual
payphone and hook it up there.

Greets://
Yo I wanna thank the guy who taught me how to phreak, his name is The1, also I wanna
thank cyrus for your constructive criticism and mikecc for testing my tutorial out
(even tho ive tried explaining it to ya before). I’ll be releasing more phreaking
tutorials later and only on ODSOURCE.COM so look for them.

Speeding up menus in XP

Go to Start --> Run --> Regedt32

Go to HKEY_CURRENT_USER\Control Panel\Desktop

Locate the key called "MenuShowDelay" and it is probably set to 400.

Change that value to 150.

Reboot your computer.

You should notice a slight increase in the speed of your menus

Single-click To Open An Item..., IF the Folder Options is grayed out

"Single-click to open an item" IF the Folder Options is grayed out... beer.gif


When you open Folder Options, the entry Single-click to open an item (point to select) is dimmed. This happens if classic shell is enforced. The option Show Common tasks in folders will also grayed out. This may be a network policy setting. If your system is in a Domain, the best option is to contact your network admin. For standalone PCs, try the setting given below.


RESOLUTION

Open Registry Editor (Regedit.exe) and navigate to:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
-and-

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Backup the registry (export the branch) before modifying the values. Read this document for more information

In the right-pane, set ClassicShell to 0. Restart for the changes to take effect. The "Single click" folder option should now be restored.

If the problem persist and if you are using Windows XP Professional Edition, load the Group Policy Editor (GPEDIT.MSC) and go to:

User Configuration | Windows components | Windows Explorer
Double-click the entry "Turn on classic shell" and set it to "Not Configured

The difference between DVD-R, DVD+R, DVD+RW and DVD-RW

The difference between DVD-R, DVD+R, DVD+RW and DVD-RW explained

There's DVD+R, DVD+RW, DVD-R, DVD-RW, and even DVD-ROM! So what's the difference between all of these different names, aren't all DVDs the same? Well, it's not quite that simple.

Let's first start with the most obvious difference: some have R and some have RW. The "R" stands for readable, while the "W" stands for writeable.

The main difference between DVD-R and DVD-RW, or DVD+R and DVD+RW is that the R disc formats can only be written to once, and then it is only readable and can’t be erased for the rest of its digital life. While RW discs are can be written to and erased many times, they are both readable and writeable.

"R" discs are perfect if they are only needed to be written to once, such as giving some files to a friend or transferring them between PCs. "RW" discs have their strength in the ability to be used many times over, which is great for routine system backups, etc. And naturally, the RW discs are slightly more expensive than the R discs, but you'll have to decide if the trade offs are worth the money.

Now, onto the difference between DVD-R and DVD+R. As I just described above, DVD-R & DVD-RW are sister discs, the difference being one is writeable once, while the other is writeable multiple times. The same thing is true for DVD+R & DVD+RW. So the question is, what's the difference between the plus and minus?

In order to explain this we must take a trip back in time. When DVDs were first being developed, there was no industry standard. Multiple companies were competing to develop what they hoped would be the dominant form of the future.

The DVD-R DVD+R difference can easily be summarized by the following:

* The DVD-R/RW standard was developed by Pioneer, and is used primarily by Apple and Pioneer. These "minus" discs can only be written to in one layer on the discs surface. In addition, this format is supported by the DVD forum, but is in no way an industry standard. DVD-R/RW discs are cheaper than the "plus" format.
* The DVD+R/RW format is supported by Philips, Dell, Sony, HP, and Mcft. These discs can be written to in multiple layers, giving them slightly better and more disc storage than the "minus" format. Because of this additional capacity, they are slightly more expensive than "minus" discs.

A couple final things to clear up is the difference between DVD-ROM and DVD+RW, or the other DVD formats I mentioned above. The DVD-ROM drive can only read DVDs, while the other DVD drives can read and write data to DVDs.

And naturally the DVD+RW CD+RW difference can be explained by the "DVD" or "CD" prefix. DVDs, on average, can store up to 4.7 GB of data, while a CD can only store about 700 MB of data, or about 15% of a DVD's capacity. While CDs are slightly cheaper, in my opinion, the benefits of DVDs are much greater.

So now that you've learned about the difference between DVD-R, DVD+R, DVD-RW, DVD+RW, and even DVD-ROM, which one is right for you? The easiest way to determine which is more beneficial is to watch the industry trends. A few years ago all pre-built computers were shipping with DVD-ROM drives. Today, most PCs have a burnable DVD drive.

I feel that the benefits of having a burnable DVD drive far outweigh any additional costs. They store much more data, and they are ideal for storing your home movies to watch on your DVD player.

My advice is to look at DVD burners that support all of the major formats I've mentioned above, DVD-R, DVD+R, DVD-RW, and DVD+RW. While a DVD drive that supports all of these formats may be slightly more expensive, it will allow you to use any type of DVD disc to burn to, and you'll be protected from any industry shifts to one format or the other.

Speed Up Internet

Speed Up Internet

Windows 2k/XP

1. First, open the Windows Registry using Regedit, and (after backing up) navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ServiceProvider
2. Note the following lines (all hex dwords):
Class = 008 ( biggrin.gif - indicates that TCP/IP is a name service provider, don't change
LocalPriority = 1f3 (499) - local names cache
HostsPriority = 1f4 (500) - the HOSTS file
DnsPriority = 7d0 (2000) - DNS
NetbtPriority = 7d1 (2001) - NetBT name-resolution, including WINS
3. What we're aiming to do is increase the priority of the last 4 settings, while keeping their order. The valid range is from -32768 to +32767 and lower numbers mean higher priority compared to other services. What we're aiming at is lower numbers without going to extremes, something like what's shown below should work well:
4. Change the "Priority" lines to:
LocalPriority = 005 (5) - local names cache
HostsPriority = 006 (6) - the HOSTS file
DnsPriority = 007 (7) - DNS
NetbtPriority = 008 ( biggrin.gif - NetBT name-resolution, including WINS
5. Reboot for changes to take effect

2. Windows 9x/ME

1. The tweak is essentialy the same as in Windows 2000/XP, just the location in the Registry is slightly different. For a more detailed description see the Windows 2000/XP section above
2. Open the Windows Registry using Regedit, and (after backing up) navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\ServiceProvider
3. You should see the following settings:
Class=hex:08,00,00,00

LocalPriority=hex:f3,01,00,00
HostsPriority=hex:f4,01,00,00
DnsPriority=hex:d0,07,00,00
NetbtPriority=hex:d1,07,00,00
4. The "priority" lines should be changed to:
LocalPriority=hex:05,00,00,00
HostsPriority=hex:06,00,00,00
DnsPriority=hex:07,00,00,00
NetbtPriority=hex:08,00,00,00
5. Reboot for changes to take effect

3. System.ini IRQ Tweak - Windows 9x/ME ONLY

1. Find your Network Card's IRQ

1. In order to add the entry to your System.ini file, you'd first have to find your NIC's IRQ
2. Right-click on My Computer icon on your Desktop, then left-click on Properties (a shortcut for that would be to press the 'Windows' + 'Pause' keys). Navigate to Device Manager and double-click on Computer. Under "View Resources" you will find a list of IRQs, each with description of the device that's using it. Note the IRQ number used by your Network Adapter

2. Adding the entry to System.ini

1. Once you've found the IRQ of your Network Card, you need to reserve some RAM for its use, by adding an entry to the System.ini file. You can edit the file in any text editor, however the easiest way is to use Windows' built in "System Configuration Editor"
2. Navigate to Start > Run and type sysedit . Find the [386enh] Section in the System.ini file and add Irq[n]=4096 under it, where [n] is the IRQ number of your NIC and 4096 is the amount of RAM you want to reserve in Kbytes. We recommend using 4096, however you can experiment with different values if you want. Save changes in the file, exit and reboot for changes to take effect.
Note: If you choose to try different values, keep in mind that reserving too much RAM for your NIC will decrease the amount of RAM available for applications, while reserving too little might not give the desired effect

3. Additional Thoughts
1. The only negative effect of the System.ini IRQ tweak is that it will reduce the amount of RAM available for running applications a bit, by reserving some specifically for your Network Card's use. The gain in performance usually outweighs the negative effect by far, considering any Computer with 32Mb of RAM or more
2. This tweak may or may not work for you. It is not a documented tweak by Windows
3. Keep in mind that if you add hardware to your system the IRQ of the Network Adapter might change, in which case you will need to modify the setting in System.ini
4. In systems with multiple NICs, you might want to add the setting for both IRQs. Also, you could reserve RAM for other IRQs if you wish, just use common sense and don't forget it reduces the amount of RAM available for running applications
5. If you are using an USB device, it does not have a specific IRQ, however you can try adding the entry using the IRQ of the USB Controller
6. For internal Cable Modems, you'd have to add the entry using the IRQ of your modem, rather than the IRQ of a Network Card


RESULTS WILL VARY

::::TCP\IP: A Mammoth Description By Ankit Fadia ankit@bol.net.in::::

TCP\IP or Transmission Control Protocol \ Internet Protocol is a stack or collection of various protocols. A
protocol is basically the commands or instructions using which two computers within a local network or the
Internet can exchange data or information and resources.

Transmission Control Protocol \ Internet Protocol or the TCP\IP was developed around the time of the
ARPAnet. It is also known as the Protocol Suite. It consists of various protocols but as the TCP
(Transmission Control Protocol) and the IP (Internet Protocol) are the most, well known of the suite of
protocols, the entire family or suite is called the TCP\IP suite.

The TCP\ IP Suite is a stacked suite with various layers stacked on each other, each layer looking after one
aspect of the data transfer. Data is transferred from one layer to the other. The Entire TCP\ IP suite can be
broken down into the below layers-:

Layer Name Protocol

Link Layer (Hardware, Ethernet) ARP, RARP, PPP, Ether
Network Layer(The Invisible Layer) IP, ICMP
Transport Layer UDP, TCP
Application Layer(The Visible Layer) The Actual running Applications like-: FTP client, Browser
Physical Layer (Not part of TCP \IP) Physical Data Cables, Telephone wires

Data travels from the Link Layer down to the Physical Layer at the source and at the destination it travels
from the Physical Layer to the Link Layer. We will later discuss what each layer and each protocol does.

The TCP\IP suite not only helps to transfer data but also has to correct various problems that might occur
during the data transfer. There are basically two types of most common errors that might occur during the
process of data transfer. They are-:

Data Corruption -: In this kind of error, the data reaches the destination after getting corrupted.
Data Loss -: In this kind of error, the entire collection of packets which constitute the data to be transferred
does not reach the destination.

TCP\IP expects such errors to take place and has certain features which prevent, such error which might
occur.

Checksums-: A checksum is a value (Normally, a 16 Bit Value) that is formed by summing up the Binary
Data in the used program for a given data block. The program being used is responsible for the calculation
of the Checksum value. The data being sent by the program sends this calculated checksum value, along
with the data packets to the destination. When the program running at the destination receives the data
packets, it re-calculates the Checksum value. If the Checksum value calculated by the Destination program
matches with the Checksum Value attached to the Data Packets by the Source Program match, then the data
transfer is said to be valid and error free. Checksum is calculated by adding up all the octets in a datagram.


Packet Sequencing-: All data being transferred on the net is broken down into packets at the source and
joined together at the destination. The data is broken down into packets in a particular sequence at the
source. This means that, for example, the first byte has the first sequence number and the second byte the
second sequence number and so on. These packets are free to travel independently on the net, so
sometimes, when the data packets reach the destination they arrive, out of sequence, which means that the
packet which had the first sequence number attached to it does not reach the destination first. Sequencing
defines the order in which the hosts receive the data packets or messages. The application or the layer
running at the destination automatically builds up the data from the sequence number in each packet.
The source system breaks the data to be transferred into smaller packets and assigns each packet a unique
sequence number. When the destination gets the packets, it's starts rearranging the packets by reading the
sequence numbers of each packet to make the data received usable.

For example, say you want to transfer a 18000 octet file. Not all networks can handle the entire 18000
octet packets at a time. So the huge file is broken down into smaller say 300 octet packets. Each packet has
been assigned a unique sequence number. Now when the packets reach the destination the packets are put
back together to get the usable data. Now during the transportation process, as the packets can move
independently on the net, it is possible that the packet 5 will arrive at the destination before packet 4
arrives. In such a situation, the sequence numbers are used by the destination to rearrange the data packets
in such a way that even if Data packet 5 arrived earlier, Packet 4 will always precede Packet 5.

A data can easily be corrupted while it is being transferred from the source to the destination. Now if a
error control service is running then if it detects data corruption, then it asks the source to re-send the
packets of data. Thus only non corrupted data reaches the destination. An error control service detects and
controls the same two types of errors-:

1.) Data Loss
2.) Data Corruption

The Checksum values are used to detect if the data has been modified or corrupted during the transfer from
source to destination or any corruption in the communication channel which may have caused data loss.
Data Corruption is detected by the Checksum Values and by performing Cyclic Redundancy Checks
(CRC 's). CRC 's too like the Checksums are integer values but require intensely advanced calculation and
hence are rarely used.

There is yet another way of detecting data corruption-: Handshaking.

This feature ensures demands that both the source and destination must transmit and receive
acknowledgement messages, that confirm transfer of uncorrupted data. Such acknowledgement messages
are known as ACK messages.

Let's take an example of a typical scenario of data transfer between two systems.
Source Sends MSG1 to Destination. It will not send MSG2 to Destination unless and until it gets the MSG
ACK and destination will not send more requests for data or the next request message (MSG2) unless it
gets the ACK from Source confirming that the MSG1 ACK was received by it. If the source does not get a
ACK message from the destination, then something which is called a timed-out occurs and the source will
re send the data to destination.

So this means that if A sends a data packet to B and B checksums the data packet and finds the data
corrupted, then it can simply delete for a time out to take place. Once the time out takes place, A will re
send the data packet to B. But this kind of system of deleting corrupt data is not used as it is inefficient and
time consuming.

Instead of deleting the corrupt data and waiting for a time out to take place, the destination (B) sends a not
acknowledged or NACK message to source(A). When A gets the NACK message, instead of waiting for a
time out to take place, it straightaway resends the data packet.

An ACK message of 1000 would mean that all data up to 1000 octets has been received till now.

TCP/ IP is a layered suite of protocols. All layers are equally important and with the absence of even a
single layer, data transfer would not have been possible. Each TCP/ IP layer contributes to the entire
process of data transfer. An excellent example, is when you send an email. For sending mail there is a
separate protocol, the SMTP protocol which belongs to the Application layer. The SMTP Application
protocol like all other application layer protocols assumes that there is a reliable connection existing
between the two computers. For the SMTP application protocol to do what it is designed for, i.e. to send
mail, it requires the existence of all other Layers as well. The Physical Layer i.e. cables and wires is
required to transport the data physically. The Transmission Control Protocol or the TCP protocol which
belongs to the Transport Layer is needed to keep track of the number of packets sent and for error
correction. It is this protocol that makes sure that the data reaches the other end. The TCP protocol is called
by the Application Protocol to ensure error free communication between the source and destination. For the
TCP layer to do its work properly i.e. to ensure that the data packets reach the destination, it requires the
existence of the Internet Protocol or IP. The IP protocol contains the Checksum and Source and
Destination IP address.

You may wonder why do we need different protocols like TCP and IP and why not bundle them into the
same Application protocol.? The TCP protocol contains commands or functions which are needed by
various application protocols like FTP, SMTP and also HTTP. The TCP protocol also calls on the IP
protocol, which in turn contains commands or functions which some application protocols require while
others don?t. So rather than bundling the entire TCP and IP protocol set into specific application protocols,
it is better to have different protocols which are called whenever required.

The Link Layer which is the Hardware or Ethernet layer is also needed for transportation of the data
packets. The PPP or the Point to Point Protocol belongs to this layer. Before we go on let's get accustomed
with certain TCP\IP terms. Most people get confused between datagrams and packets and think that they
are one and the same thing . You see, a datagram is a unit of data which is used by various protocols and a
packet is a physical object or thing which moves on a physical medium like a wire. There is a remarkable
difference between a Packet and a Datagram, but it is beyond the scope of this book. To make things easier
I will use only the term datagram (Actually this is the official term.)while discussing various protocols.

Two different main protocols are involved in transporting packets from source to destination.

1.) The Transmission Control Protocol or the TCP Protocol
2.) The Internet Protocol or the IP protocol.

Besides these two main protocols, the Physical Layer and the Ethernet Layer are also indispensable to data
transfer.

THE TRANSPORT LAYER

The TCP protocol

The Transmission Control Protocol is responsible for breaking up the data into smaller datagrams and
putting the datagrams back to form usable data at the destination. It also resends the lost datagrams to
destination where the received datagrams are reassembled in the right order. The TCP protocol does the
bulk of work but without the IP protocol, it cannot transfer data.

Let's take an example to make things more clearer. Let's say your Internet Protocol Address or IP address is
xxx.xxx.xxx.xxx or simply x and the destination's IP is yyy.yyy.yyy.yyy or simply y. Now As soon as the
three-way connection is established between x and y, x knows the destination IP address and also the Port
to which it is connected to. Both x and y are in different networks which can handle different sized packets.
So in order to send datagrams which are in receivable size, x must know what is the maximum datagram
size which y can handle. This too is determined by both x and y during connection time.

So once x knows the maximum size of the datagram which y can handle, it breaks down the data into
smaller chunks or datagrams. Each datagram has it's own TCP header which too is put by TCP.
A TCP Header contains a lot of information, but the most important of it is the Source and Destination IP
and Port numbers and yes also the sequence number.

**************
HACKING TRUTH: Learn more about Ports, IP's, Sockets in the Net Tools Manual
**************
The source which is your computer(x) now knows what the IP Addresses and Port Numbers of the
Destination and Source computers are. It now calculates the Checksum value by adding up all the octets of
the datagram and puts the final checksum value to the TCP Header. The different octets and not the
datagrams are then numbered. An octet would be a smaller broken down form of the entire data. TCP then
puts all this information into the TCP header of each datagram. A TCP Header of a datagram would finally
look like -:


+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Source Port | Destination Port |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Sequence Number |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Acknowledgment Number |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Data | |U|A|P|R|S|F| |
| Offset| Reserved |R|C|S|S|Y|I| Window |
| | |G|K|H|T|N|N| |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Checksum | Urgent Pointer |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| The Actual Data form the next 500 octets |
| |


There are certain new fields in the TCP header which you may not know off. Let's see what these new
fields signify. The Windows field specifies the octets of new data which is ready to be processed. You see
not all computers connected to the Internet run at the same speed and to ensure that a faster system does not
send datagrams to a slow system at a rate which is faster than it can handle, we use the Window field. As
the computer receives data , the space in the Window field gets decreased indicating that the receiver has
received the data. When it reaches zero the sender stops sending further packets. Once the receiver finishes
processing the received data, it increases the Window field, which in turn indicates that the receiver has
processed the earlier sent data and is ready to receive more chunks of data.

The Urgent Field tells the remote computer to stop processing the last octet and instead receive the new
octet. This is normally not commonly used.

The TCP protocol is a reliable protocol, which means that we have a guarantee that the data will arrive at
the destination properly and without any errors. It ensures that the data being received by the receiving end
is arranged in the same correct order in which it was sent.

The TCP Protocol relies on a virtual circuit between the client and the host. The circuit is opened via a 3
part process known as the three part handshake. It supports full duplex transportation of data which means
that it provides a path for two way data transfer. Hence using the TCP protocol, a computer can send and
receive datagrams at the same time.

Some common flags of TCP are-:

RST [RESET]- Resets the connection.
PSH [PUSH] - Tells receiver to pass all queued data to the application running.
FIN [FINISH] - Closes connection following the 4 step process.
SYN Flag - means that the machine sending this flag wants to establish a three way handshake i.e.
a TCP connection. The receiver of a SYN flag usually responds with an ACK message.

So now we are in a position to represent a three way TCP Handshake:

A <---SYN---> B
A <---SYN/ACK? B
A <---ACK---> B

A sends a SYN flag to B saying " I want to establish a TCP connection", B responds to the SYN with the
ACK to the SYN flag. A again responds to the ACK sent by B with another ACK.

Read RFC 793 for further in depth details about the TCP protocol.

The User Datagram Protocol or the UDP Protocol

The User Data protocol or the UDP is yet another protocol which is a member of the Transport Layer. TCP
is the standard protocol used by all systems for communications. TCP is used to break down the data to be
transported into smaller datagrams, before they (the datagrams) are sent across a network. Thus we can say
that TCP is used where more than a single or multiple datagrams are involved.

Sometimes, the data to be transported is able to fit into a single datagram. We do not need to break the data
into smaller datagrams as the size of the data is pretty small. The perfect example of such data is the DNS
system. To send out the query for a particular domain name, a single datagram is more than enough. Also
the IP that is returned by the Domain Name Server does not require more than one datagram for
transportation. So in such cases instead of making use of the complex TCP protocol, applications fall back
to the UDP protocol.

The UDP protocol works almost the way TCP works. But the only differences being that TCP breaks the
data to be transferred into smaller chunks, does sequencing by inserting a sequence number in the header
and no error control. Thus we can conclude by saying that the UDP protocol is an unreliable protocol with
no way to confirm that the data has reached the destination.

The UDP protocol does insert a USP header to the single datagram it is transporting. The UDP header
contains the Source and Destination IP Addresses and Port Numbers and also the Checksum value. The
UDP header is comparatively smaller than the TCP Header.

It is used by those applications where small chunks of data are involved. It offers services to the User's
Network Applications like NFS(Network File Sharing) and SNMP.

Read RFC 768 for further in depth details about the UDP protocol.

THE NETWORK LAYER

The IP Protocol

Both the TCP and the UDP protocols, after inserting the headers to the datagram(s) given to them pass
them to the Internet Protocol or the IP Protocol. The main job of the IP protocol is to find a way of
transporting the datagrams to the destination receiver. It does not do any kind of error checking.

The IP protocol too adds it's own IP Header to each datagram. The IP header contains the source and
destination IP addresses, the protocol number and yet another checksum. The IP header of a particular
datagram looks like-:

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|Version| IHL |Type of Service| Total Length |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Identification |Flags| Fragment Offset |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Time to Live | Protocol | Header Checksum |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Source Address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Destination Address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| TCP header info followed by the actual data being transferred|
| |


The Source and destination IP addresses and needed so that?well it is obvious isn't it? The Protocol
number is added so that the IP protocol knows to which Transport Protocol the datagram has to be passed.
You see various Transport Protocols are used like for example TCP or UDP. So this protocol number is
inserted to tell IP the protocol to which the datagram has to be passed.

It too inserts it's own Checksum value which is different from the Checksum Value inserted by the
Transport Protocols. This Checksum has to be inserted as without it the Internet Protocol will not be able to
verify if the Header has been damaged in the transfer process and hence the datagram might reach a wrong
destination. The Time to Live field specifies a value which is decreased each time the datagram passes
through a network. Remember Tracert?

The Internet Protocol Header contains other fields as well, but they are quite advanced and cannot be
included in a manual which gives an introduction to the TCP\IP protocol. To learn more about the IP
protocol read RFC 791.

The Internet Control Message Protocol or the ICMP

The ICMP protocol allows hosts to transfer information on errors that might have occurred during the data
transfer between two hosts. It is basically used to display error messages about errors that might occur
during the data transfer. The ICMP is a very simple protocol without any headers. It is most commonly
used to diagnose Network Problems. The famous utility PING is a part of the ICMP protocol. ICMP
requests do not require the user or application to mention any port number as all ICMP requests are
answered by the Network Software itself. The ICMP protocol too handles only a single datagram. That's
why we say in PING only a single datagram is sent to the remote computer. This protocol can remote many
network problems like Host Down, Congested Network etc

Read RFC 792 for further in depth details about the ICMP protocol.

The Link Layer

Almost all networks use Ethernet. Each machine in a network has it's own IP address and it's Ether
Address. The Ether Address of a computer is different than it's IP address. An Ether Address is a 42 bit
address while the IP address is only a 32 bit address. A Network must know which computer to deliver the
datagram to. Right? For this the Ether Header is used.

The Ether Header is a 14 octet header that contains the Source and Destination Ethernet address, and a type
code. Ether too calculates it's own Checksum value. The Type code relates to the protocol families to be
used within the Network. The Ether Layer passes the datagram to the protocol specified by this field after
inserting the Ether Header. There is simply no connection between the Ethernet Address and the IP address
of a machine. Each machine needs to have a Ethernet to IP address translation table on its hard disk.

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Ethernet destination address (first 32 bits) |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Ethernet dest (last 16 bits) |Ethernet source (first 16 bits) |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Ethernet source address (last 32 bits) |

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Ethernet Checksum |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Address Resolution Protocol or ARP

Data before being transmitted across the Internet or across a local network is broken down into smaller
Packets which are suitable for transfer over the net. These packets have the Source and Destination IP's but
for the transfer to take place the suitable Hardware Addresses or the MAC addresses must also be known.
That is where ARP comes in.

To get the Hardware MAC addresses, ARP or Address Resolution Protocol sends a request message. The
Router replies with the Hardware Address. It is similar to the DNS and it too has a cache. This cache can be
a bit vulnerable as a Hacker could forge a connection from a remote machine claiming to be one of the
cached locations. So we can conclude that ARP translates IP's into Ethernet Addresses. One thing to
remember about ARP is that it only translates outgoing packets.

There is also something called the RARP which is an abbreviation for Reverse Address Resolution
Protocol, which like the name says does exactly reverse of what ARP does.

There is simply no algorithm to get the Ethernet Address from the IP Address. To carry out such
translations, each computer has a file which has a table with rows for each computer and two columns for
their corresponding IP address and Ethernet Address. The File is somewhat like the following-:

Internet Protocol Address Ethernet Address
Computer Name xxx.xy.yy.yx 08-00-39-00-2F-C3

Say there are a system in a Network (A) and an unidentified system (B) contacts it. Now A only knows the
IP address of B. Now A will first try to identify whether B is the same network so that it can directly
communicate via Ethernet. So it will first check the IP to MAC address translation table which it has. If it
finds the IP in the table then well and good and A will establish a connection with B via Ethernet.

On the Other hand if A does not find any match for the specific IP, it will send out a request in the form of
a 'Broadcast'. All computers within the Network will receive this broadcast and will search their own IP to
MAC translation table and will reply with the necessary MAC address. A basic difference between an Ip
address and MAC address is that an IP is the form xxx.xxx.xxx.xxx and a MAC address is in the form
xx:xx:xx:xx:xx:xx and one is 32 bit while the other is 40 bit.

Read RFC 826 for further in depth details about the ARP protocol.

Application Layer

Till now you have learnt how data is broken down into smaller chunks, and transferred to the destination,
where the chunks are rearranged. But there is yet another aspect to a successful data transfer process, which
we have not discussed yet: The Application Protocols and the Application Layer itself. A host which
receives datagrams has many applications or services (daemons) running which are ready to establish a
TCP connection and accept a message. Datagrams travelling on the Internet must know which application
they have to establish connection with, which application they have to send the message to. A typical web
server will have the FTP daemon, the HTTP daemon, the POP daemon, and the SMTP daemon running.
Wouldn't the datagrams get confused as to which daemon to send the message to.

For the datagrams to know which computer to send the message to, we have IP addresses. The datagram
knows what daemon or application to send the message to by the Port Number attached to the IP address of
the Destination. A TCP address is actually fully described by 4 numbers; The IP address of the Source and
Destination and the TCP Port Numbers of each end to which data is to be sent. These numbers are found in
the TCP Header.

To make it simpler to understand I have included an excerpt from the Net Tools Chapter:

What is all the hype about socket programming? What exactly are sockets?

TCP\IP or Transmission Control Protocol\ Internet Protocol is the language or the protocol used by
computers to communicate with each other over the Internet. Say a computer whose IP address is
99.99.99.99 wants to communicate with another machine whose IP address is 98.98.98.98 then would will
happen?

The machine whose IP is 99.99.99.99 sends a packet addressed to another machine whose IP is
98.98.98.98. When 98.98.98.98 receives the packet then it verifies that it got the message by sending a
signal back to 99.99.99.99.But say the person who is using 99.99.99.99 wants to have simultaneously more
than one connections to 98.98.98.98.....then what will happen? Say 99.99.99.99 wants to connect to
the FTP daemon and download a file by FTP and at the same time it wants to connect to 98.98.98.98's
website i.e. The HTTP daemon. Then 98.98.98.98. will have 2 connects with 99.99.99.99 simultaneously.
Now how can 98.98.98.98.distinguish between the two connections...how does 98.98.98.98. know which
is for the FTP daemon and which for the HTTP daemon? If there was no way to distinguish between the
two connections then they would both get mixed up and there would be a lot of chaos with the message
meant for the HTTP daemon going to the FTP daemon. To avoid such confusion we have ports. At each
port a particular service or daemon is running by default. So now that the 99.99.99.99 computers knows
which port to connect to, to download a FTP file and which port to connect to, to download the web page,
it will communicate with the 98.98.98.98 machine using what is known as the socket pair which is a
combination of an IP address and a Port. So in the above case the message which is meant for the FTP
daemon will be addressed to 98.98.98.98 : 21 (Notice the colon and the default FTP port suceeding it.).
So that the receiving machine i.e. 98.98.98.98 will know for which service this message is meant for and to
which port it should be directed to.

In TCP\IP or over the Internet all communication is done using the Socket pair i.e. the combination of the
IP address and the port.

The Application Layers basically consists of the Applications running on your computer and the
Applications running on the host to which you are connected. Say you are viewing the Hotmail Site, then
the application layer comprises of the Web Browser running on your computer and the HTTP daemon
running at Hotmail's server and the Application Protocol being used to communicate is HyperText Transfer
Protocol.

As soon as a TCP connection is established the Applications running on Each end decide the language or
protocol to be used to communicate and send datagrams.

IP Spoofing Torn Apart

IP spoofing is the most exciting topic you will hear wannabe hackers talking about. It is also a subject
about which no one knows much. Before we continue I would like to tell you that IP Spoofing is quite
difficult to understand and a lot of people have trouble understanding how it is done. The other downside it
has is the fact that it can almost not be done using a Windows system and a system administrator can easily
protect his system from IP spoofing

So what is IP Spoofing? IP Spoofing is a trick played on servers to fool the target computer into thinking
that it is receiving data from a source other than you. This in turn basically means to send data to a remote
host so that it believes that the data is coming from a computer whose IP address is something other than
yours. Let's take an example to make it clear:

Your IP is : 203.45.98.01 (REAL)
IP of Victim computer is: 202.14.12.1 (VICTIM)
IP you want data to be sent from: 173.23.45.89 (FAKE)

Normally sitting on the computer whose IP is REAL, the datagrams you send to VICTIM will appear to
have come from REAL. Now consider a situation in which you want to send a datagram to VICTIM and
make him believe that it came from a computer whose IP is FAKE. This is when you perform IP Spoofing.

The Main problem with IP Spoofing is that even if you are able to send a spoofed datagram to the remote
host, the remote host will reply not to your real IP but to the Fake IP you made your datagram seem to have
come from. Getting confused? Read the following example to clear up your mind.

Taking the same IP's as in the last example, consider the following scenario. Now, if REAL connects to
VICTIM, after the standard three way handshake has taken place, and VICTIM sends an ACK message to
REAL. Now if you spoof you IP, to say FAKE, then VICTIM will try to establish a TCP connection and
will send an ACK message to FAKE. Now lets assume that FAKE is alive, then as it had not requested the
ACK message (sent by VICTIM to FAKE) it will reply with a NACK message which would basically end
the connection and no further communication between FAKE and VICTIM would take place. Now if
FAKE doesn't exist then the ACK message sent by VICTIM will not get any reply and in the end the
connection times out.

Due to this FAKE and REAL IP reasons, when a person is trying to perform an IP Spoof, he does not get
any response from the remote host and has no clue whether he has been successful or not. If he has made
any progress or not. You are as good as blind, with no medium through which you could get feedback.

IP Spoofing can be successful only if the computer with the FAKE IP does not reply to the victim and not
interrupt the spoofed connection. Take the example of a telephone conversation, you can call up a person
' x ' and pretend to be ' y ' as long as ' y ' does not interrupt the conversation and give the game away.

So why would you need to perform IP Spoofing-:

1.) To Pretend that you are some other computer whose IP address is amongst the trusted list of computers
on the victim's disk. This way you are exploit the 'r' services and gain access to the network as you are
then believed to be from a trusted source.
2.) To Disguise or Mask your IP address so that the victim does not know who you really are and where
the data is coming from.

If you ever read the alt.2600 or the alt.hacking newsgroup, you would probably find many postings like "I
have Win98, how do I Spoof my IP" or even " I do not know TCP/IP. tell me how to perform IP spoofing".
You see the very fact that they are posting such questions and expect to learn how to spoof their IP without
even knowing a bit about TCP\IP, confirms the fact that they would not be able to perform IP Spoofing. No
I am not saying that asking questions is bad, but you see not knowing something is not so bad, but not
knowing something and showing ignorance towards learning it is really, really bad.

You see IP spoofing is a very complex and difficult to perform subject. You need to hog entire TCP/IP and
Networking Protocols manuals and need to be able to write C programs which will help you in the
Spoofing process. It is amazing how people even think that they can spoof their IP without even knowing
what TCP/IP stands for.

You see all packets travelling across the Internet have headers which contain the source and destination IP
addresses and port numbers, so that the packet knows where to go and the destination knows where the
packet has come from and where to respond. Now the process of Spoofing means to change the source IP
address contains by the Header of the packet, in turn fooling the receiver of the Packets into believing that
the packet came from somewhere else, which is a fake IP. Now let's again look at the IP Header of a
datagram.

Now basically to perform IP spoofing we need to be able to change the value of the field, Source Address.
Now to this you need to be able to guess sequence numbers which is quite a sophisticated process and I will
try to explain it as clearly as possible. Before we go on, you need to understand the fact the IP spoofing is
not the entire process, it is just a stepping stop in the entire process of fooling the remote host and
establishing a trust relationship with the remote host.

So how do these trust relationships take place? Well all of you are encountered with some form of
authentication process or the other. Now the Username-Password pair is the most commonly used form of
authentication, with which we are very much familiar. Now what happens in the Username-Password form
of authentication is that the remote host to which the client is connected to challenges the client by asking
the User to type in the Username and Password. So in this form of authentication, the User needs to
intervened and the remote host challenges the user to enter the Username and Password which act as a from
of authentication.

Now other than the Password-Username form of authentication there is yet another form of authentication
most users do not know of. This is the Client IP. In this form of authentication, what happens is that the
remote host gets or find out the IP address of the client and compares it with a predefined list of IP's. If the
IP of the client who is trying to establish a connection with the remote host is found in the list of IP's
maintained by the host, then it allows the client access to the shell 'without a password' as the identity of
the client has already been authenticated.

Such kind of rust relationships are common in Unix Systems which have certain 'R services' like rsh ,
rlogin , rcp which have certain security problems and should be avoided. Despite the threat involved most
ISP's in India still keep the ports of the R services open to be exploited by Hackers. You normally establish
a Rlogin trust relationship by using the Unix command,

$>rlogin IP address

**************
HACKING TRUTH: Well there is definitely a cooler way of establishing a trust relationship with a remote
host, using Telnet. The default port numbers at which the R services run are 512, 513,514
**************

So how do I spoof my IP? Well in short, to spoof your IP, you need to be able to predict sequence numbers,
this will clearer after reading then next few paragraphs.

To understand Sequence Numbers you need to go back to, how the TCP protocol works. You already
know that TCP is a reliable protocol and has certain in-built features which have the ability to rearrange, re-
send lost, duplicated or out of sequence data. To make sure that the destination is able to rearrange the
datagrams in the correct order, TCP inserts two sequence numbers into each TCP datagram. One Sequence
number tells the receiving computer where a particular datagram belongs while the second sequence
number says how much data has been received by the sender. Anyway, let's move on, TCP also relies on
ACK and NACK messages to ensure that all datagrams have reached the destination error free.
Now we need to reanalyze the TCP Header to understand certain other aspects of sequence numbers and
the ACK Number.

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Source Port | Destination Port |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Sequence Number |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Acknowledgment Number |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Checksum | Urgent Pointer |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| The Actual Data form the next 500 octets |
| |

You see the TCP Header contains a Sequence Number which actually represents the sequence number of
the first byte of that particular TCP segment. A sequence number is a 32 Bit number which is attached to
all bytes (data) being exchanged across a Network. The ACK Number Field in the TCP header, actually
contains the value of the sequence number which it expects to be the next. Not only that, it also does what
it was meant to do, acknowledge data received. Confused? Read it again till you get the hang of it.

When a connection is established, the initial sequence number or ISN is initialized to 1. This ISN number
is then incremented by 128,000 every second. There is a certain patter according to which the sequence
numbers increment or change which makes then easy to predict.

To successfully perform IP spoofing or in order to predict Sequence Numbers, you need to be running a
form of UNIX, as Windows does not provide the users with access to really advanced system stuff.
Without a form of Unix IP Spoofing is almost impossible to do.

This text is not the ultimate guide to IP Spoofing and was aimed at only giving you a general outline of the
whole process. Sequence number Prediction is really, really sophisticated and difficult to understand, but
not impossible to do. However a system administrator can easily save his systems from IP spoofing and this
actually makes it quite useless, nonetheless truly exciting. If You really want to learn IP Spoofing I suggest
you read IP Spoofing Demystified by daemon9/route/infinity which was a part of Issue 48 of PHRACK
magazine, File 14 of 18. Go to the Archive Section of their site, http://www.phrack.com and click on Issue
48.

This brings me to the other purpose people use IP Spoofing, IP Masking. Now to something as simple as
mask or hide your IP you do not need to go through the complex procedure of guessing sequence numbers
and performing IP Spoofing. There are proxy servers to do that for you. Read the Net Tools chapter for
further details.

Port Scanning in Networking Terms

Earlier we learnt what a Port scan is why it is considered to be such a important tool of getting information
about the remote host, which in turn can be used to exploit any vulnerabilities and break into the system.
We all know how a manual Port Scan works. You launch Telnet and manually Telnet to each Port jotting
down information that you think is important. In a manual Port Scan, when you telnet to a port of a remote
host, a full three way handshake takes place, which means that a complete TCP connection opens.

The earliest and the oldest version of Port Scanners used the same technique. They connected to each port
and established a full three way handshake for a complete TCP connection. The downside of such port
scanners was the fact that as a full TCP connection was being established, the system administrator could
easily detect that someone is trying to port scan his systems to find a vulnerability. However such port
scanning methods also had a bright side, as an actual TCP connection was being established, the port
scanning software did not have to build a Fake Internet Protocol Packet. (This IP Packet is used to scan the
remote systems.) Such TCP scanners too relied on the three-way TCP handshake to detect if a port is open
or not. The Basic process of detecting whether a port is open or not has been described below:

1.) You send a TCP Packet containing the SYN flag to remote host.
2.) Now the remote host checks whether the port is open or not. If the port is open then it replies with a
TCP packet containing both an ACK message confirming that the port is open and a SYN flag. On the
other hand if the port is closed then the remote host sends the RST flag which resets the connection, in
short closes the connection.
3.) This third phase is optional and involves the sending of an ACK message by the client.

As TCP Scanners were detectable, programmers around the world developed a new kind of port scanner,
the SYN Scanner, which did not establish a complete TCP connection. These kinds of port scanners remain
undetectable by only sending the first single TCP Packet containing the SYN flag and establishing a half
TCP Connection. T understand the working of a SYN or Half SYN Port Scanner simply read its 4 step
working-:

1. SYN Port Scanner sends the first TCP packet containing the SYN flag to the remote host.
2. The remote system replies with, either a SYN plus ACK or a RST.
3. When the SYN Port scanner receives one of the above responses, it knows whether the respective port
is open or not and whether a daemon is ready listening for connections.

The SYN Port Scanners were undetectable by most normal system port scan detectors, however newer post
scan detectors like netstat and also some firewalls can filter out such scans. Another downside to such
scanning is that the method in which the scanner makes the IP packet varies from system to system.

UDP Scanning

It is yet another port scanning technique which can be used to scan a UDP port to see if it is listening. To
detect an open UDP port, simply send a single UDP Packet to the port. If it is listening, you will get the
response, if it is not, then ICMP takes over and displays the error message, " Destination Port
Unreachable".

FIN Port Scanners

FIN Port Scanners are my favorite type of port scanners. They send a single packet containg the FIN flag. If
the remote host returns a RST flag then the port is closed, if no RST flag is returned, then it is open and
listening.

Some port scanners also use the technique of sending a ACK packet and if the Time To Live or ttl of the
returning packets is lower than the RST packets received (earlier), or if the windows size is greater than
zero, then the port is probably open and listening.

The Following is the code of a supposedly Stealth Port Scanner which appeared in the Phrack Magazine.

/*
* scantcp.c
*
* version 1.32
*
* Scans for listening TCP ports by sending packets to them and waiting for
* replies. Relys upon the TCP specs and some TCP implementation bugs found
* when viewing tcpdump logs.
*
* As always, portions recycled (eventually, with some stops) from n00k.c
* (Wow, that little piece of code I wrote long ago still serves as the base
* interface for newer tools)
*
* Technique:
* 1. Active scanning: not supported - why bother.
*
* 2. Half-open scanning:
* a. send SYN
* b. if reply is SYN|ACK send RST, port is listening
* c. if reply is RST, port is not listening
*
* 3. Stealth scanning: (works on nearly all systems tested)
* a. sends FIN
* b. if RST is returned, not listening.
* c. otherwise, port is probably listening.
*
* (This bug in many TCP implementations is not limited to FIN only; in fact
* many other flag combinations will have similar effects. FIN alone was
* selected because always returns a plain RST when not listening, and the
* code here was fit to handle RSTs already so it took me like 2 minutes
* to add this scanning method)
*
* 4. Stealth scanning: (may not work on all systems)
* a. sends ACK
* b. waits for RST
* c. if TTL is low or window is not 0, port is probably listening.
*
* (stealth scanning was created after I watched some tcpdump logs with
* these symptoms. The low-TTL implementation bug is currently believed
* to appear on Linux only, the non-zero window on ACK seems to exists on
* all BSDs.)
*
* CHANGES:
* --------
* 0. (v1.0)
* - First code, worked but was put aside since I didn't have time nor
* need to continue developing it.
* 1. (v1.1)
* - BASE CODE MOSTLY REWRITTEN (the old code wasn't that maintainable)
* - Added code to actually enforce the usecond-delay without usleep()
* (replies might be lost if usleep()ing)
* 2. (v1.2)
* - Added another stealth scanning method (FIN).
* Tested and passed on:
* AIX 3
* AIX 4
* IRIX 5.3
* SunOS 4.1.3
* System V 4.0
* Linux
* FreeBSD
* Solaris
*
* Tested and failed on:
* Cisco router with services on ( IOS 11.0)
*
* 3. (v1.21)
* - Code commented since I intend on abandoning this for a while.
*
* 4. (v1.3)
* - Resending for ports that weren't replied for.
* (took some modifications in the internal structures. this also
* makes it possible to use non-linear port ranges
* (say 1-1024 and 6000))
*
* 5. (v1.31)
* - Flood detection - will slow up the sending rate if not replies are
* recieved for STCP_THRESHOLD consecutive sends. Saves alot of resends
* on easily-flooded networks.
*
* 6. (v1.32)
* - Multiple port ranges support.
* The format is: |[,|,...]
*
* Examples: 20-26,113
* 20-100,113-150,6000,6660-6669
*
* PLANNED: (when I have time for this)
* ------------------------------------
* (v2.x) - Multiple flag combination selections, smart algorithm to point
* out uncommon replies and cross-check them with another flag

Introduction

Although many organizations have deployed antivirus software, malicious software such as computer viruses, worms, and Trojan horses continue to infect computer systems around the world. There is no single reason for this apparent contradiction, but the current situation indicates that the standard approach of deploying antivirus software on each computer in your environment may not be sufficient.

The Antivirus Defense-in-Depth Guide provides an easy to understand overview of different types of malware, or malicious software, including information about the risks they pose, malware characteristics, means of replication, and payloads. The guide details considerations for planning and implementing a comprehensive antivirus defense for your organization, and provides information on defense-in-depth planning and related tools that you can use to help reduce your risk of infection. The final chapter of the guide provides a comprehensive methodology to help you quickly and effectively respond to and recover from malware outbreaks or incidents.

Scheduled Tasks - Defrag, how to set up scheduled defrags

Scheduled Tasks - Defrag, how to set up scheduled defrags


oi m8s i figured this out because i ran into problems with trying to get windows task manager to defrag my hardrive at a certain time by only using built in tools.

Step 1

open up notepad (or favorite editor) and type:


defrag c:
defrag d:
defrag e:
defrag f:
defrag g:
defrag j:


make sure to change the drive letters to one that match your system. After you have customized the drive letters save the file as defrag_script.BAT or whatever is easy for you to remeber. Just make sure its a ".BAT" file. I saved the file into a dir in my documents called scripts but you can put it anywhere.

Step 2

Now that you have the script already made open your control panel and click on "Scheduled Tasks".

Select file>new>Scheduled Task

it should create a file on oin the window called "New Task" slect this and right click to properties.

In the run box click browse and navigate to your script. make sure that you run it with an account that has administrator rights otherwise it might not work.

Now select the schedule tab from the top and input the time and how often. I chose to urn it every noght however you could probably run it once a week and still be fine.

After yo uset the time and how often have a look in the settings tab and see if you need to change anything. Then click okay and your done!


you can also modify the script further by adding various operations on the ends of the defrag command:
CODE

-a Analyze Only
-f Force defragmentation even if free space is low
-v verbose output
-? Display help text


You can also pipe the command defrag to a log file if you want to see what went on the last time the script ran:
CODE

--this form will rewirte the log file erasing any previous info--
defrag x: -v > x:/logs/defrag_log.txt

--this form will append the new info to the end of the old--
defrag x: -v >> x:/logs/defrag_log.txt

Slow Loggon Time, one fix for problem

My problem was a 1 min login delay due the aktiveds.dll that loads at startup (thanks to NicTech Networks Inc.). The following advice worked for me so I guess it works for any .dll made by NicTech since they all use the same registry folder....

Open up regedit.exe and find THIS folder. Navigate to it by clicking the +'s to expand
things like you would in Windows explorer:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\Guardian


Right click over "Guardian" in the left pane.
Left click on "Permissions"
Left click "SYSTEM" once to highlight it.
Check "deny" in all boxes that you can at the bottom (Probably only 2)
Left click Apply
Left Click OK

Say "OK" to any warnings about permissions
**Reboot** the system

then problems solved

I got this information from another forum. I had this problem for about six weeks and was just about ready to reformat my hard drive. Worked great for me, hope this helps out somebody else.

Rename 'recycle Bin' To Whatever You Want

1. Start, Run, 'Regedit'.
2. Press 'Ctrl'+'F' to open find box and type 'Recycle Bin' to search.
3. Change any value data with 'Recycle Bin' to whatever name you want to give it ( ie, like 'Trash Can' or 'Dump' etc).
4. Press F3 to continue searching for 'Recycle Bin' and change wherever you come across 'Recycle Bin' to new its new name.
5. Repeat step 4 until you have finished with searching and changed all values to its new name.
6. Close regedit and hit F5 on desktop to see the new name on screen.

Note: As a good practice, always backup your registry before changing anything although changing 'Recycle Bin' name is a simple tweak and doesnt affect anything else.
