Ban Shutdown : Trick to be played with friends or lamers

This is a neat Trick that you can on that lamer that has a huge ego. You can disable shutdown option in the shutdown dialog box. This trick involve Registry editing so take the registry backup first.

Launch the Regedit.exe and goto
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right pane look for NoClose key.
Set its value to 1

doing this disables the Shutdown option in the Shutdown dialog box.
Generally XP and newer version do not give any message.
but older versions give messsage like
"This opoeration has been cancelled due to restriction in effect of this computer. Please contact your system Administrator "


You can re enable the Shutdown option by making NoClose key value eqaul to Zero.

Firefox Search Bar Hacks

Firefox Search Bar in the upper-right corner, sitting next to the address bar, is one of the most frequently used feature inside Firefox.

You can do a lot of tweaking to the Firefox search bar like Add new search engines, delete unused search engines, change the order of search engines, delete autocomplete, change the default search engine or even resize the width of the search bar. We discuss each tip in detail here (also applicable to Flock):

How to add a new search engine to Firefox search bar ?

The Firefox Search bar comes pre-loaded with Google, Yahoo, Amazon, eBay, Answers.com, and Creative Commons search. If you'd like to add more search engines to the search bar, click on a search engine name here or browse the full directory of search engine plug-ins at mycroft. Alternatively, click the down arrow next to the G in the search box, and choose Add Engines.

How do I remove a search engine from Firefox search bar ?

To Uninstall a Firefox search plugin, open the searchplugins folder situated in the Mozilla Firefox 1.5 installation directory (C:\Program Files\Mozilla Firefox\). Sort the entire folder by name so that files selected with any search engine stay together at one place.

Delete both .src and .gif or .png search plugin files for the search engine you want to remove. For example, to remove the eBay search engine, you would delete the files "ebay.src" and "ebay.gif". Restart Firefox and the search engine will be deleted forever. Any custom search engines may be located in the Firefox Profile folder inside Windows Application Data folder.

There's even a Firefox extension for uninstalling Firefox search plugins - just right click on a search plugin and choose Delete.

How do I rearrange the order of search engines in Firefox ?

Search engines are added to Firefox search bar at the bottom. As your list of search engine grows, you may want to sort the order and place the maximum used search engine at the top. Here's how change the order in which the engines are shown in the Firefox search bar.

Type about:config in the Firefox location bar.
Type browser.search.order in the filter.
Now change the values as you wish to reorder.

For example, to make Yahoo as the top engine and Google just next, make the following changes:
browser.search.order.1 = Yahoo
browser.search.order.2 = Google

The other easy option to change the order is download Search Plugin Manager that lets you re-sort the search plugin list in the Mozilla Firefox browser as well as rename, edit, delete or hide search plugins.

How do I delete autocomplete entries (history) inside the Search Bar ?

The Firefox search bar and some form fields on web pages have autocomplete dropdowns that appear with a list of previously-entered data. To delete individual entries, Click on the text area, press down to activate autocomplete, highlight the entry you want deleted, and press Shift + Delete.

You can clear the previous searches from the Search Bar. Just right-click it and select "Clear Search History".

You can disable the display of autocomplete entries by adding the following lines to userChrome.css
/* Remove autocomplete dropdown */
#PopupAutoComplete > .autocomplete-tree { display: none !important; }

How do I customize a search engine plugin in 30 seconds ?
Say you have already installed a search plugin that uses www.google.com. You want to change the default behaviour so that the same plugin now searches using www.google.co.in or google.es if you are in Spain.

Open the searchplugins folder located inside the Firefox installation directory. Open the file google.src with a text editor like notepad and make a simple change in the following line
action="http://www.google.com/search"
change this to..
action="http://www.google.co.in/search" or
action="http://www.google.es/search"

Save the file, quite notepad and restart Firefox.

Using the Firefox Search Bar - Keyboard Shortcuts

To search, click in the Search Bar (or press "Ctrl+K") and start typing. Hit "Enter" and your search will be run. You can use "Alt+Enter" to open search results in a new tab.

The Search Bar supports more than one search engine. To see the list of available engines click the icon at the left of the bar, and a list showing the choices will appear. You can also use "Ctrl+Up"/"Ctrl+Down" to cycle between the available choices.

FTP Error Messages

Some nice info about ftp error codes so you know what they mean. i am sure you see them all the time and sometimes you dont know what they mean, so take a look here.

The most common codes:
421 - often means: too many users logged to the same account.

530 - wrong login:pass, some servers auto-switch to 530 from

421 when they reach the max # of users. so notice the error message attached to the code.

550 - common in Ratio site, If the file exsist it means you have no access to the file or dir.
if you try changing dirs in an FTP and you`re getting a 550 message, it means you don`t have access to the dir ,but ,It doesn`t mean you don`t have access to a dir inside that dir. (meaning when getting a direct path, log into the path directly, not 1 dir by 1.

All others:

110 Restart marker reply. In this case, the text is exact and not left to the particular implementation; it must read: MARK yyyy = mmmm Where yyyy is User-process data stream marker, and mmmm server’s equivalent marker (note the spaces between markers and “=”).

120 Service ready in nnn minutes.

125 Data connection already open; transfer starting.

150 File status okay; about to open data connection.

200 Command okay.

202 Command not implemented, superfluous at this site.

211 System status, or system help reply.

212 Directory status.

213 File status.

214 Help message. On how to use the server or the meaning of a particular non-standard command. This reply is useful only to the human user.

215 NAME system type. Where NAME is an official system name from the list in the Assigned Numbers document.

220 Service ready for new user.

221 Service closing control connection. Logged out if appropriate.

225 Data connection open; no transfer in progress.

226 Closing data connection. Requested file action successful (for example, file transfer or file abort).

227 Entering Passive Mode (h1,h2,h3,h4,p1,p2).

230 User logged in, proceed.

250 Requested file action okay, completed.

257 “PATHNAME” created.

331 User name okay, need password.

332 Need account for login.

350 Requested file action pending further information.

421 Too many users logged to the same account

425 Can’t open data connection.

426 Connection closed; transfer aborted.

450 Requested file action not taken. File unavailable (e.g., file busy).

451 Requested action aborted: local error in processing.

452 Requested action not taken. Insufficient storage space in system.

500 Syntax error, command unrecognized. This may include errors such as command line too
long.

501 Syntax error in parameters or arguments.

502 Command not implemented.

503 Bad sequence of commands.

504 Command not implemented for that parameter.

530 Not logged in.

532 Need account for storing files.

550 Requested action not taken. File unavailable (e.g., file not found, no access).

551 Requested action aborted: page type unknown.

552 Requested file action aborted. Exceeded storage allocation (for current directory or
dataset).

553 Requested action not taken. File name not allowed.

How to Open Password Protected PDF Documents

There are sometimes genuine reasons to unlock or crack a password protected PDF file. You have the legal right to open the encrypted PDF document but forgot the password like in the case below.

Say one of your former colleague created some critical sales reports in PDF format but he is not working with the company anymore. In his absence, you have no option but to crack the PDF password in order to open, read or print these PDF files.

There are basically two types of PDF protection - the original PDF creator can either restrict opening the PDF file itself or he can restrict others from modifying, printing or copying text and graphics from the PDF file. Here are a few possible workarounds:

When there are Copying or Printing Restrictions..

Say you want to print a couple of pages from the PDF document but the document settings won't let you do that.

Open the document in Acrobat Reader or Foxit and capture the PDF page as an image using any free screen capture software. If there are multiple pages, you may try SnagIt since it can autoscroll and capture multiple pages of the document in one-go.

If you want to copy just a portion of text from some PDF page, use a screen capture tool with OCR features (like Kleptomania, Capture Text discussed here)

Alternatively, you can invest in commercial solutions like Advanced PDF Password Recovery from ElcomSoft and PDF Password Remover from Very PDF.

(These utilities may not recover the password for you - they'll just remove the restrictions from the password protected file)

When there are Document Opening Restrictions..

This is a very tricky case and there's no straight-forward solution to read PDF documents that are password-protected at the Open level.

The software will use methods like Brute Force, Key Search and Dictionary Attack to guess the password. They will try to use all possible character combinations as the password and so the process might take hours or even days and would really depend on your computer's processing power.

Legal Issues: - you maybe surprised to learn that these PDF password cracking software are absolutely legal and Microsoft even awarded ElcomSoft a Gold Certified Partner status.

Thinks to know About google.

1-->The name 'Google' is a spelling error. The founders of the site thought they were going for 'Googol'.

2-->The reason the Google page is so bare is because the founders didn't know HTML and just wanted a quick interface.

3-->Google started as a research project by Larry Page and Sergey Brin when they were 24 and 23 years old respectively.

4-->Google receives about 200 million search queries each day from every part of the world, including Antarctica and Vatican.

5-->In the earliest stage of Google,there was no the submit button rather a hit on the ENTER key.

6-->You can have the Google home page set up in 88 different languages including Urdu,Latin and Klingon.

7-->It would take 5,707 years for a person to search Google's 3 billion pages. The Google software does it in .5 seconds.

8-->The logos that appear on the Google homepage during noteworthy daysare called Google Doodle.

9-->You've heard of Google Earth,but not many know there is a site called Google Moon,Which maps the lunar surface.

10-->Keyhole,the satellite imaging company that Google acquired in October 2004,was funded by the CIA.

Solution : "Registry Editing has been disabled by your administrator"

If u ever encountered above error, i.e. "Registry editing has been disabled by your administrator" on Windows XP or any other Windows NT Operating system, this may help u! I have encountered the above error while patching registry. Even manual "regedit" was not working!

Here is simple solution....

Click "Start >> Run" or press "[window key + R ]" and type this command exactly as given below (or u can copy-paste it too...)

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

Solution : Yahoo tracks you!!

As you all know, Yahoo! upgraded its features and the capacities of the mail accounts have grown to 1GB. That's good for sure, but the "monitoring" methods that we all have been far too familiar with in the last couple of years have been renewed with this move also. Yahoo! is now keeping track of which sites its members that are getting into groups or using Yahoo! services are visiting and storing this data with a method called "Web Beacons". The aim is to give these statistics to the partner companies arranged by agreement and to improve the "advertisement guiding" function.

However, those who are bothered by this and do not want to be kept track of have still a choice. Yahoo! has hidden this option way deep inside somewhere


1. Go to the address
http://privacy.yahoo.com/privacy

and click the "Cookies" link under the "Special Topics" column.

2. Click the "Web Beacons" link under the "Reference Links" Column.

3. On this page, click the "click here to opt out" link toward the end of the third paragraph under the "Outside the Yahoo! Network" title.

4. After a while, a page that says you have been out of the monitoring program will load. Without doing anything, close that page or continue your usual surfing by typing another address in the address bar. (Do NOT click the "Cancel Opt-out" button, your action will be cancelled!)

5. You're done! Now Yahoo! will not record what you're doing during surfing.

You can let your friends that might be interested know about this; since no matter how "innocent" it may seem, it's still a violation of privacy

note:

Did you know that Yahoo now tracks every LINK or AD that a user MAY HAVE SEEN ON THE PAGE. They now accumulate 1 Terra byte of data every 1 days

Four Generations of Firewall

A firewall is a network gateway that enforces security rules on the conversion of peer-to-peer communications. Essentially, a firewall creates a boundary between two or more networks. A firewall is usually configured as a bastion host or a dual-homed bastion host. It evaluates each network packet against a network security policy, which is a collection of security rules, conventions, and procedures governing communications into and out of a network. Usually, IP traffic forwarding is disabled on the firewall to ensure that all traffic between the internal network and external networks passes through the firewall server, thereby allowing the firewall to inspect all network packets that traverse the network boundary.


Most firewall technologies provide different capabilities for auditing communication events. Usually, the firewalls generate audit records detailing the cause and circumstances surrounding the triggering of audit events. As firewall technology improves, firewalls inspect additional network packet information, use more sophisticated inspection algorithms, maintain more state information, and inspect the network packets at more network layers. As such, more mature firewall technology provides more detailed audit records, or summary information, about the network packets that are allowed through or prevented from traversing the firewall. By analyzing such audit records, administrators can often detect network security policy problems, such as attempts to break in or misconfiguration of the firewall's network security policy enforcement features. As a general rule, more detailed and descriptive audit record information yields better monitoring capabilities in a firewall product.



Before Cisco Centri Firewall, firewalls inspected network traffic using one of four architectural models, which are defined by the information that they examine to make security-relevant decisions. In the next four sections, we define these different architectures in detail.

How Packet Filters Work :


A packet filter firewall is a first-generation firewall technology that analyzes network traffic at the transport protocol layer. Each IP network packet is examined to see if it matches one of a set of rules defining what data flows are allowed. These rules identify whether communication is allowed based upon information contained within the internet and transport layer headers and the direction in which the packet is headed (internal to external network or vice-versa).

Packet filters typically enable you to manipulate (that is, permit or prohibit) the transfer of data based on the following controls:

* the physical network interface that the packet arrives on
* the address the data is (supposedly) coming from (source IP address)
* the address the data is going to (destination IP address)
* the type of transport layer (TCP, UDP, ICMP)
* the transport layer source port
* the transport layer destination port

Note This architecture implements a very limited command set to perform analysis for one or more network protocols; however, it performs its inspection in kernel space.

Packet filters generally do not understand the application layer protocols used in the communication packets. Instead, they work by applying a rule set that is maintained in the TCP/IP kernel. This rule set contains an associated action that will be applied to any packets matching the criteria mentioned above.
Advertisement

The action taken may take on one of two values: "deny" or "permit" the network packet. Two lists, the deny list and the permit list, are maintained in the kernel. For a network packet to be routed to its proper destination, it must first pass a check of both the deny and permit lists. That is, it must not be expressly denied, and it must be expressly permitted. Some packet filters that are incorporated into router hardware implement a different policy. In these types of packet filters, the packet must be expressly denied or else it is permitted. In order for you to understand the filtering rules, you must consider the security stance utilized by the routing hardware.

Packet filters typically implement command sets that allow the checking of the source and destination port numbers on the TCP and UDP transport layer protocols. This check determines whether an applicable permit or deny rule exists for that specific port and protocol combination. Due to the fact that the ICMP protocol layer does not utilize port numbers for its communications protocol, it is difficult for packet filters to apply any security policy to this form of network traffic. In order to apply an effective security policy to ICMP, the packet filter must maintain state tables to ensure that an ICMP reply message was recently requested from an internal host. This ability to track communications state is one of the primary differences between simple packet filters and dynamic packet filters.

Because packet filters are implemented in the network layer, they generally do not understand how to process state information in the high-level protocols, such as FTP. The more sophisticated packet filters are able to detect IP, TCP, UDP, and ICMP. Using a packet filter that includes the TCP/UDP port filtering capability, you can permit certain types of connections to be made to specific computers while prohibiting other types of connections to those computers and similar connections to other computers.

The complete network packet inspection adheres to the following general algorithm:

* If no matching rule is found, then drop the network packet.
* If a matching rule is found that permits the communication, then allow peer-to-peer communication.
* If a matching rule is found that denies the communication, then drop the network packet.

Because this type of firewall does not inspect the network packet's application layer data and does not track the state of connections, this solution is the least secure of the firewall technologies. It allows access through the firewall with a minimal amount of scrutiny. In other words, if the checks succeed, the network packet is allowed to be routed through the firewall as defined by the rules in the firewalls routing table. However, because it does less processing than the other technologies, it is the fastest firewall technology available and is often implemented in hardware solutions, such as IP routers.

Packet filter firewalls often readdress network packets so that outgoing traffic appears to have originated from a different host rather than an internal host. The process of readdressing network packets is called network address translation. Network address translation hides the topology and addressing schemes of trusted networks from untrusted networks.
