make any folder and add your image file and the other file (which you wanna hide behind image) and after that make a new archive and add both the file into that new archive. see in this figure.
I have a two file named alone.php and devil.php now I want to hide devil.php in to the alone.jpg so for that I have created new archive and I have named it new.rar and I have added both the files into new.rar
now open command prompt and go to your folder location. and execute bellow command.
copy /b alone.jpg + new.rar safe.jpg
And hit enter after that you will see the screen like bellow.

How To: Change Your Ip In Less Then 1 Minute
1. Click on "Start" in the bottom left hand corner of screen
2. Click on "Run"
3. Type in "command" and hit ok
You should now be at an MSDOS prompt screen.
4. Type "ipconfig /release" just like that, and hit "enter"
5. Type "exit" and leave the prompt
6. Right-click on "Network Places" or "My Network Places" on your desktop.
7. Click on "properties"
You should now be on a screen with something titled "Local Area Connection", or something close to that, and, if you have a network hooked up, all of your other networks.
8. Right click on "Local Area Connection" and click "properties"
9. Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab
10. Click on "Use the following IP address" under the "General" tab
11. Create an IP address (It doesn't matter what it is. I just type 1 and 2 until i fill the area up).
12. Press "Tab" and it should automatically fill in the "Subnet Mask" section with default numbers.
13. Hit the "Ok" button here
14. Hit the "Ok" button again
You should now be back to the "Local Area Connection" screen.
15. Right-click back on "Local Area Connection" and go to properties again.
16. Go back to the "TCP/IP" settings
17. This time, select "Obtain an IP address automatically"
tongue.gif 18. Hit "Ok"
19. Hit "Ok" again
20. You now have a new IP address
With a little practice, you can easily get this process down to 15 seconds.
P.S:
This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back

How to Hack A Lan Connaction helpe This Command
HACK LAN
How to Hack A Lan Connaction helpe This Command
First, open your Network Connection and right click and select Properties. Then Select TCP/IP and click on Properties again. Now Click on Advanced and WINS tab. Select Default for NeBIOS.
Now back to the main Local Area Connection window, select File and Print Sharing for Mic*ft Networks and hit enter.
This is just to make sure you have NetBIOS enabled. We will have some fun with NetBIOS on CMD.
First thing you need to know is some very helpfull commands to use on CMD(Command Prompt).
In case you don’t know how to get CMD open in your box, then click on Start, then Run, then type “cmd” (no quotes, off course… you know the drill).
Back to commands:
In case you don’t know some of them, then just type the command on CMD and hit enter. A little help will show up in your screen. Read it and understand what the command does.
Lets start easy…
1) ping : This command will allow you to know if the host you pinging is alive, which means if it is up at the time of executing the “ping” command.
CODE
ping x.x.x.x (x is the IP address)
or
ping www.whatever.com (www.whatever.com is the website you want to ping, but you don’t know the IP)
OBS: Keep in mind that if the host you pinging is blocking ICMP packets, then the result will be host down.
2) nslookup : This command has many functionalities.
One is for resolving DNS into IP.
Lets say you know the website URL but you don’t know its IP(and you want to find out).
nslookup www.whatever.com (www.whatever.com is the website you want to find out the IP)
Now, another really nice function of nslookup is to find out IP of specific Mail Severs.
QUOTE
nslookup (enter)
set type=mx (enter)
yahoo.com
This command will give you the mail server IP of yahoo.com. You can use whatever server you want and if it is listed on DNS, then you get the IP. Simple, isn’t it?
OK, now why would you want to have an IP of a mail server?
To send spoofed mail to your friends or even for SE.
In case you looking for “How to spoof email”, then look for my “How to spoof email tutorial” http://www.infowar.com/forums/showthread.p…p;threadid=2360
3) tracert : This command will give you the hops that a packet will travel to reach its final destination.
OBS: This command is good to know the route a packet takes before it goes to the target box.
CODE
tracert x.x.x.x (x is the IP address)
or
tracert www.whatever.com (www.whatever.com is the website you don’t know the IP)
4) arp : This command will show you the arp table. This is good to know if someone is doing arp poisoning in your LAN.
QUOTE
arp -a
5) route : This command will show you the routing table, gateway, interface and metric.
CODE
route print
6) ipconfig : This command will show tons of very helpful things.
Your IP, gateway, dns in use.
CODE
ipconfig
or
CODE
ipconfig /all
this command will give all that info but for all networks you might have it.
Also, in case you have a dynamic IP and want to change it, then type…
CODE
ipconfig /release (this will release your IP)
ipconfig /renew (this will renew your iP)
OBS: Keep in mind that those commands will change your IP, but the new IP will still be tighed up to you. So don’t do anything stupid.
7) netstat : This command will show you connection to your box.
CODE
netstat
or
CODE
netstat -a (this will show you all the listening ports and connection with DNS names)
netstat -n (this will show you all the open connection with IP addresses)
netstat -an (this will combined both of the above)
8) nbtstat : This command will show you the netbios name of the target box.
CODE
nbtstat -A x.x.x.x (x is the IP address)
nbtstat -a computername
net view x.x.x.x or computername (will list the available sharing folders on the target box)
Now some hints:
CODE
net use \ipaddressipc$ “” /user:administrator
(this command will allow you to connect to the target box as administrator)
Now if you want to connect to the target box and browse the entire C drive, then use this command:
CODE
net use K: \computernameC$
(this will create a virtual drive on your “my computer” folder)
OBS: Keep in mind that this will only works if the target box doesn’t have an administrator password set.
And least but not last, the “help” command.
CODE
whatevercommand /help
CODE
whatevercommand /?
This command will help you to understand what it does and all the switchs available for each command.
Very useful if you know the command, but forgot the right switch.

How to Change Windows Start Button name / hack...
Window's Tweak: Hack Your Start Button
written by ::::: http://mastermindloltricks.blogspot.in :::::
I've gotten so many requests on how to change the Windows XP Start button, I'm going to teach you how to hack it to pieces manually.
Before you get started, you might want to print out this page for easy reference.
Change the Start text:
1. First of all, make sure you download Resource Hacker. You'll need this puppy to edit resources inside your Windows shell.
2. Locate explorer.exe in your c:\Windows directory. Make a copy of the file in the same directory and rename it explorer.bak.
3. Now launch Resource Hacker. In the File menu, open explorer.exe. You'll now see a bunch of collapsed folders.
4. Expand the String Table folder and then find folder No. 37 (folder No. 38 if you're in Windows Classic mode).
5. Click on resource 1033 and locate the text that says "Start." This is your Start button, and now you've got control over what it says! Change the "Start" text to your text of choice. You don't have a character limit, but the text takes up valuable taskbar space, so don't make it too long.
6. Click on the button labeled Compile Script. This updates the settings for your Start button. But nothing will happen until you complete through step #20, so keep going!
Change your hover text
7. While you're here, why not also change the text that pops up when your mouse hovers over your Start button?
8. Right now it says "Click here to begin." Well, duh! We already know that's where to begin!
9. Open folder No. 34 and click on resource 1033.
10. Find the text that says "Click here to begin" and change it to something cooler. Might I suggest "Click here for a good time, baby."
11. Click on the Compile Script button to update this resource.
Customize your Start icon
12. For an added bonus, you can also change the Windows icon to the left of the text, too.
13.
Collapse the String Table folder and expand the Bitmap folder at the top of your folder list.
14. Click on folder No. 143 and click on resource 1033. You should see that familiar Windows icon.
15. Go to the Action Menu and select "Replace bitmap." Select "Open file with new bitmap", and locate the replacement image on your machine. Note: The image must have a .bmp extension and a size of 25 pixels by 20 pixels. Then click the Replace button.
Here's the image I've been using instead of the Windows icon, in case you want to use it.
16.
Now that you've made your changes, save the file in your Windows folder with another name, such as newstartbutton.exe. Don't name it Explorer.exe, because that file is already being used by your system. Close all open programs and restart your system.
17. Boot into Safe Mode With Command Prompt by pressing F8 on startup. Then choose Safe Mode in the command prompt.
18. Log on as administrator and enter your password.
19.
When the command prompt comes up, make sure you're in the right directory by typing "cd c:\windows" (without the quotes).
20. Now type "copy c:\windows\newstartbutton.exe c:\windows\explorer.exe" (no quotes). Type "yes" (no quotes) to overwrite the existing file, then restart your system by typing "shutdown -r" (no quotes).
When Windows relaunches, you'll see your new Start button in all its glory!

How to Change Text on XP Start Button.
Step 1 - Modify
Explorer.exe File
In order to make the
changes, the file explorer.exe located at C:\Windows needs to be edited. Since
explorer.exe is a binary file it requires a special editor. For purposes of
this article I have used Resource Hacker. Resource HackerTM is a freeware
utility to view, modify, rename, add, delete and extract resources in 32bit
Windows executables and resource files (*.res). It incorporates an internal
resource script compiler and decompiler and works on Microsoft Windows
95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.
get this from
http://delphi.icm.edu.pl/ftp/tools/ResHack.zip
The first step is to
make a backup copy of the file explorer.exe located at C:\Windows\explorer.
Place it in a folder somewhere on your hard drive where it will be safe. Start
Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe.
The category we are
going to be using is "String Table". Expand it by clicking the plus
sign then navigate down to and expand string 37 followed by highlighting 1033.
If you are using the Classic Layout rather than the XP Layout, use number 38.
The right hand pane will display the stringtable. We’re going to modify item
578, currently showing the word “start” just as it displays on the current
Start button.
There is no magic
here. Just double click on the word “start” so that it’s highlighted, making
sure the quotation marks are not part of the highlight. They need to remain in
place, surrounding the new text that you’ll type. Go ahead and type your new
entry. In my case I used Click Me!
You’ll notice that
after the new text string has been entered the Compile Script button that was
grayed out is now active. I won’t get into what’s involved in compiling a
script, but suffice it to say it’s going to make this exercise worthwhile.
Click Compile Script and then save the altered file using the Save As command
on the File Menu. Do not use the Save command – Make sure to use the Save As
command and choose a name for the file. Save the newly named file to
C:\Windows.
Step 2 – Modify the
Registry
!!!make a backup of
your registry before making changes!!!
Now that the modified
explorer.exe has been created it’s necessary to modify the registry so the file
will be recognized when the user logs on to the system. If you don’t know how
to access the registry I’m not sure this article is for you, but just in case
it’s a temporary memory lapse, go to Start (soon to be something else) Run and
type regedit in the Open field. Navigate to:
HKEY_LOCAL_MACHINE\
SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon
In the right pane,
double click the "Shell" entry to open the Edit String dialog box. In
Value data: line, enter the name that was used to save the modified
explorer.exe file. Click OK.
Close Registry Editor
and either log off the system and log back in, or reboot the entire system if
that’s your preference. If all went as planned you should see your new Start
button with the revised text.[/b]

How Much Bandwidth Is Enough?,Hosting Bandwidth,Network Connectivity,Bandwidth Explained!
This is well written explanation about bandwidth, very useful info.
BandWidth Explained
Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.
Network Connectivity
The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.
If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousands of DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54).
Traffic
A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middle of rush hour, you may travel very slowly since all of the lanes are being used up.
Traffic is simply the number of bits that are transferred on network connections. It is easiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds 1000 folders. Each folder has 100 papers. Each paper contains 100 characters - A GB is all the characters in the building. An MP3 song is about 4MB, the same song in wav format is about 40MB, a full length movie can be 800MB to 1000MB (1000MB = 1GB).
If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you are the only person accessing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, if three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and transfer a small portion at a time so each person's file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfers would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost due to upgrading equipment).
Hosting Bandwidth
In the example above, we discussed traffic in terms of downloading an MP3 file. However, each time you visit a web site, you are creating traffic, because in order to view that web page on your computer, the web page is first downloaded to your computer (between the web site and you) which is then displayed using your browser software (Internet Explorer, Netscape, etc.) . The page itself is simply a file that creates traffic just like the MP3 file in the example above (however, a web page is usually much smaller than a music file).
A web page may be very small or large depending upon the amount of text and the number and quality of images integrated within the web page. For example, the home page for CNN.com is about 200KB (200 Kilobytes = 200,000 bytes = 1,600,000 bits). This is typically large for a web page. In comparison, Yahoo's home page is about 70KB.
How Much Bandwidth Is Enough?
It depends (don't you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just how much is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis
If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:
Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor
If you intend to allow people to download files from your site, your bandwidth calculation should be:
[(Average Daily Visitors x Average Page Views x Average Page Size) +
(Average Daily File Downloads x Average File Size)] x 31 x Fudge Factor
Let us examine each item in the formula:
Average Daily Visitors - The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1,000,000.
Average Page Views - On average, the number of web pages you expect a person to view. If you have 50 web pages in your web site, an average person may only view 5 of those pages each time they visit.
Average Page Size - The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.
Average Daily File Downloads - The number of downloads you expect to occur on your site. This is a function of the numbers of visitors and how many times a visitor downloads a file, on average, each day.
Average File Size - Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.
Fudge Factor - A number greater than 1. Using 1.5 would be safe, which assumes that your estimate is off by 50%. However, if you were very unsure, you could use 2 or 3 to ensure that your bandwidth requirements are more than met.
Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why our formula takes daily averages and multiplies them by 31.
Summary
Most personal or small business sites will not need more than 1GB of bandwidth per month. If you have a web site that is composed of static web pages and you expect little traffic to your site on a daily basis, go with a low bandwidth plan. If you go over the amount of bandwidth allocated in your plan, your hosting company could charge you over usage fees, so if you think the traffic to your site will be significant, you may want to go through the calculations above to estimate the amount of bandwidth required in a hosting plan.

Backtracking EMAIL to Messages
Tracking email back to its source: Twisted Evil
cause i hate spammers... Evil or Very Mad
Ask most people how they determine who sent them an email message and the response is almost universally, "By the From line." Unfortunately this symptomatic of the current confusion among internet users as to where particular messages come from and who is spreading spam and viruses. The "From" header is little more than a courtesy to the person receiving the message. People spreading spam and viruses are rarely courteous. In short, if there is any question about where a particular email message came from the safe bet is to assume the "From" header is forged.
So how do you determine where a message actually came from? You have to understand how email messages are put together in order to backtrack an email message. SMTP is a text based protocol for transferring messages across the internet. A series of headers are placed in front of the data portion of the message. By examining the headers you can usually backtrack a message to the source network, sometimes the source host. A more detailed essay on reading email headers can be found .
If you are using Outlook or Outlook Express you can view the headers by right clicking on the message and selecting properties or options.
Below are listed the headers of an actual spam message I received. I've changed my email address and the name of my server for obvious reasons. I've also double spaced the headers to make them more readable.

According to the From header this message is from Maricela Paulson at s359dyxxt@yahoo.com. I could just fire off a message to abuse@yahoo.com, but that would be waste of time. This message didn't come from yahoo's email service.
The header most likely to be useful in determining the actual source of an email message is the Received header. According to the top-most Received header this message was received from the host 12-218-172-108.client.mchsi.com with the ip address of 21.218.172.108 by my server mailhost.example.com. An important item to consider is at what point in the chain does the email system become untrusted? I consider anything beyond my own email server to be an unreliable source of information. Because this header was generated by my email server it is reasonable for me to accept it at face value.
The next Received header (which is chronologically the first) shows the remote email server accepting the message from the host 0udjou with the ip 193.12.169.0. Those of you who know anything about IP will realize that that is not a valid host IP address. In addition, any hostname that ends in client.mchsi.com is unlikely to be an authorized email server. This has every sign of being a cracked client system.
Here's is where we start digging. By default Windows is somewhat lacking in network diagnostic tools; however, you can use the tools at to do your own checking.
davar@nqh9k:[/home/davar] $whois 12.218.172.108
AT&T WorldNet Services ATT (NET-12-0-0-0-1)

# ARIN WHOIS database, last updated 2003-12-31 19:15
# Enter ? for additional hints on searching ARIN's WHOIS database.
I can also verify the hostname of the remote server by using nslookup, although in this particular instance, my email server has already provided both the IP address and the hostname.
davar@nqh9k:[/home/davar] $nslookup 12.218.172.108
Server: localhost
Address: 127.0.0.1
Name: 12-218-172-108.client.mchsi.com
Address: 12.218.172.108
Ok, whois shows that Mediacom Communications owns that netblock and nslookup confirms the address to hostname mapping of the remote server,12-218-172-108.client.mchsi.com. If I preface a www in front of the domain name portion and plug that into my web browser, http://www.mchsi.com, I get Mediacom's web site.
There are few things more embarrassing to me than firing off an angry message to someone who is supposedly responsible for a problem, and being wrong. By double checking who owns the remote host's IP address using two different tools (whois and nslookup) I minimize the chance of making myself look like an idiot.
A quick glance at the web site and it appears they are an ISP. Now if I copy the entire message including the headers into a new email message and send it to abuse@mchsi.com with a short message explaining the situation, they may do something about it.
But what about Maricela Paulson? There really is no way to determine who sent a message, the best you can hope for is to find out what host sent it. Even in the case of a PGP signed messages there is no guarantee that one particular person actually pressed the send button. Obviously determining who the actual sender of an email message is much more involved than reading the From header. Hopefully this example may be of some use to other forum regulars.
