Everything You wanted to know about FIREWALLS

Everything You wanted to know about FIREWALLS..!

A firewall is basically something that protects the network from the Internet. It is derived from the concept of firewalls used in vehicles which is a barrier made of fire resistant material protecting the vehicle in case of fire. Anyway a firewall is best described as a software or hardware or both Hardware and Software packet filter that allows only selected packets to pass through from the Internet to your private internal network. A firewall is a system or a group of systems which guard a trusted network( The Internal Private Network from the untrusted network (the Internet.) To understand how a firewall works, firstly we need to understand how exactly data is transferred on the Internet.

The TCP\IP suite is responsible for successful transfer of data across a network both the Internet and the Intranet. The TCP\IP suite is a collection of protocols which are inter-related and interdependent and act as a set of rules according to which data is transferred across the network. A protocol can be defined as a language or a standard which is followed while transfer of data takes place.

A firewall relies on the source and destination IP and also the ports to control the packet transfer between the untrusted network and the trusted network. Firewalls can be classified into 3 types:

1. Packet Filter Firewalls
2. Application proxy Firewalls
3. Packet Inspection Firewalls

Packet Filter Firewalls
They are the earliest and the most criticized firewalls, which nowadays are not easily found. They are usually Hardware based i.e. Router Based (a router is a piece of device which connects two
networks together.) Whenever a Packet Filter Firewall receives a packet for permission to pass through, it compares the header information i.e. the source and destination IP address, and port number with a table of predefined access control rules If the header information matches, then the packet is allowed to pass else the packet is direct contact between the untrusted system and the trusted private system.
Such Firewalls can be fooled by using techniques like IP Spoofing in which we can change the source IP such that the firewall thinks that the packet has come from a trusted system which is among the list of systems which have access through the firewall.

Application proxy Firewalls
The shortcomings of the packet filter firewalls are addressed by the new type of firewalls developed by the DARPA. It was widely believed that the earlier type of firewalls were not secure enough as they allowed the untrusted systems to have a direct connection with the trusted systems. This problem was solved with the use of Proxy servers as firewalls. A proxy server which is used as a firewall are called application proxy servers. This kind of a proxy firewall examines what application or service (running on ports) a packet is meant for and if that particular service is available only then is the packet allowed to pass through and if the service is unavailable then the packet is discarded or dropped by the firewall.

Packet Inspection Firewalls
It can be also known as an extension of the Packet Filter Firewall. It not only verifies the source and
destination IP's and ports, it also takes into consideration or verifies that content of the data before passing it through. There are two ways in which this kind of a firewall verifies the data to
be passed:
State and Session.
In case of state inspection, an incoming packet is allowed to pass through only if there is a matching outward bound request for this packet. This means that the incoming packet is allowed to pass through only if the trusted server had requested for it or had sent an invitation for it.
In case of session filtering, the data of the incoming is not verified, but instead the network activity is traced and once a trusted system ends the session, no further packets from that system pertaining to that session are allowed to pass through.


All along you will come across many Firewalls on various systems, basically a
firewall can be established
or setup in two ways:

1. Dual-homed gateway
2. Demilitarized zone (DMZ)

In a dual homed gateway firewall, there is a single firewall with 2 connections, one for the trusted network and the other for the untrusted network.
In the case of a Demilitarized Firewall or a DMZ there are two firewalls, each with two connections, but there is a slight difference in the case of a DMZ setup.
In the case of a DMZ setup, there are two firewalls, the first having two connections, one leading to the untrusted network and the other leading to the host systems like the email server or the FTP server etc.
In the case of a Dual Homed Gateway the untrusted network is connected to the host systems (email and FTP servers etc) through a firewall and these host systems are connected to the internal private network. There is no second firewall between the host systems and the internal
private trusted network.
The basic structure of the DMZ setup declares it to be a more secure system as even if an attacker gets through the first firewall, he just reaches the host systems, while the internal network is protected by another firewall.

SPEEDING XP BY 60 TIMES

SPEEDING XP BY 60 TIMES

Speed up Booting Xp by 61 Times

run -> msconfig - Hit Enter

Whenever you start your computer, you are faced with a few moments of thumb twiddling while Windows XP boots and prompts you to log on. Although you should expect to wait for a few moments, sometimes Windows XP seems to boot rather slowly. In fact, you may notice that over a period of time the PC that used to roar to life seems a bit sluggish instead. Fortunately, you can perform several techniques that help Windows XP get the bootup speed you want. This Article explores how to put these techniques to work.



Stopping Unneeded Startup Services !


Along with the core operating system and programs that Windows XP runs when it starts, there is also a host of services involved. Many of these services are necessary for Windows XP to operate correctly. However, many of them are for features in Windows XP that you may not use at all. You can peruse the services and disable any service that you do not want to run. The fewer services that run, the more quickly Windows XP will boot.


Caution:

Exercise caution when stopping services. If you do not know what a service does or are unsure of the ramifications of stopping the service, leave it alone. Some services are critical to Windows XP's operations, so make sure you understand what the service is before you disable it.


To reduce the number of services that start on bootup, you can access two different areas of Windows XP. The first is the System Configuration Utility. The Services tab shows you the services that start when the computer boots.
You can stop a service from starting by simply clearing the check box next to the service and clicking OK. However, before you do so, there is another way to disable services that you may prefer because the interface gives you more information about the service in question.


Open Control Panel/Administrative ToolsServices or else select Start/Run, type services.msc, and click OK. Either way, you see the Services console.
I prefer to use the Services console instead of the System Configuration Utility because it describes what the service does. Additionally, you can double-click a service and examine its properties.

Notice the Startup Type column in Figure 4-2. This information lists whether the service is automatic or manual. Manual services are only started in Windows XP when you start a process that requires the service. Some other process may require the service that has a "dependency" relationship with it; in this case, the dependency service will start, as well. Because these services do not start automatically when you boot Windows XP, you do not need to do anything with manual services.


However, all services listed as automatic start when Windows XP boots. These are the services that increase boot time. As I have mentioned, many of them are necessary and important, so you should not stop automatic services from booting unless you are sure of the ramifications. You can get this information by looking at the Description column. Here's a quick look at common services you may want to live without:



SPEED UP BOOT BY DISABLING UNUSED PORTS.!!


You may have tried many tweaks like modifying windowsXP start-up applications, prefetches, unload DLLs method,etc. And yes those methods do work for me.
I have just accidentally found out another way to give you an extra boost in windowsXP's boot performance. This is done by disabling your unused devices in
Device Manager. for example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra perfromance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart.



Do Dis !!


1.Start Registry Editor (Regedit.exe).

2.Locate the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters

3.Make sure you backup the keys by exporting them to a .reg file.

4.On the EnablePrefetcher value, change the setting from 3 to 5 (decimal).

5.Close the registry editor.

6.Restart your computer



Automatic Updates !

This service enables Windows XP to check the Web automatically for updates. If you don't want to use Automatic Updates, you can disable the service. You can always check for updates manually at the Windows Update Web site.

Computer Browser: If your computer is not on a network, you don't need this service. If you are on a network, leave it alone.

DHCP Client: If you are not on a network, you do not need this service. If you are on a small workgroup, you can still increase boot time by configuring manual IP addresses (which I explore later in this chapter).

DNS Client: If you are not on a network, you do not need this service. If you are, leave it alone.

Error Reporting and Event Log: You don't have to use these services but they can be very helpful, so I would leave them configured as automatic.

Fax: If you don't use your computer for fax services, you can disable this one.

Help and Support: If you never use the Windows XP Help and Support Center (found on the Start menu), you can disable this service.

IMAPI CD-Burning COM: This service enables you to burn CDs on your computer. If you never burn CDs, you can disable the service.

Indexing Service: Your computer keeps an index of files but if you rarely search for files, the service is just a resource hog. You can stop it and turn the service to manual.

Windows Firewall/Internet Connection Sharing: If you do not use these features, you can disable them.

Infrared Monitor: If you do not use infrared devices, you can disable this service.

Messenger: This service sends alert messages on a local area network (it is not the same as Windows Messenger). If you are not on a network, you can disable this service.

Print Spooler: If you do not do any printing from the computer, you can disable this service. If you print, make sure you leave it as automatic.

Remote Registry: This service allows remote users to modify the Registry on your computer. If you are not on a network, you can disable this service.

System Restore Service: This service allows you to use System Restore. If you have turned off System Restore anyway, you do not need to turn off the service. If you do, you turn off System Restore.

Themes: If you do not use themes, you can disable this service.

Windows Image Acquisition: If you do not use scanners or digital cameras, you can disable this service.

Wireless Zero Configuration: If do not use wireless networking devices, you can disable this service.




You may have a number of other automatic services, depending on software and other configurations on your computer. So it's a good idea to look through the services and learn more about them. If you double-click a service, a Properties dialog box appears
Notice that on the General tab, you see a Startup Type drop-down menu. If you want to change an automatic service to manual, select Manual here and click OK. As a general rule, don't disable a service unless you are sure you will never use it. However, manual configuration allows the service to be started when you find it necessary, thus speeding up your boot time.
However, before you change a service to manual, look at the Dependencies tab (see Figure 4-4). This tab shows you which other services depend upon the service you are considering changing.
Keep in mind that services are necessary for the vast functionality you get with Windows XP. Change only those services that you understand and do not use. How you use your Windows XP computer should be the best guide in terms of optional startup services.



Tip !


The Indexing service and the System Restore service take up a lot of disk space and system resources across the board. You can live without the Indexing service but I suggest that you keep using System Restore. It works great when you are in a bind and this is one case where the loss of speed may not be worth the ramifications of not using System Restore.


Speed Tips and Tricks for Windows XP Startup
Aside from startup programs, services, and the Prefetch folder, there are a number of other startup procedures and issues you can modify to help Windows XP start faster. The following sections explore those tips and tricks.


Manual IP Addressing on Small Office/Home Networks
Windows XP is configured to help you take care of networking. It uses the TCP/IP protocol for networking in workgroups, or what you might call small office or home networks that do not use a dedicated server.

The problem is that automatic IP addressing can be slow. When your computer boots, it has to query the network to see what IP addresses are already in use and then assign itself one. If you want to speed up the boot time a bit, consider manually assigning IP addresses to all computers on the network. This way, the network computers do not have to worry about locating an automatic IP address. Because one is manually configured, the operating system doesn't have to spend time solving this problem.

This isn't a networking book, however, so I won't delve into the implications of using a manual IP address, but if you are using a computer that functions as a host computer to the Internet (using Internet Connection Sharing [ICS]), you can get into connectivity problems if you change the configuration of the IP address. However, you can still work around this problem by starting with the ICS host computer.

Select Start/Connect To/Show All Connections. Right-click your network adapter card and click Properties. On the General tab, select TCP/IP in the list of services and click the Properties button.

In the TCP/IP properties, you can see if you use an automatic or manual IP address. In the example in Figure 4-5, I have configured a manual IP address of 90.0.0.1 and a default subnet mask. The other computers on my office network each use a different IP address in the same class, such as 90.0.0.2, 90.0.0.3, 90.0.0.4, and so on. This way, each computer has a permanent IP address, which helps increase boot time. Note that if you change the IP addresses of your computers, they must all use the same subnet mask. A default subject mask of 255.255.255.0 will keep you in good shape.

Make sure you understand the implications of changing IP addresses on your network. If you have no networking experience at all, you may be wiser to leave the automatic IP addressing as is and try to gain some speed using the additional suggestions in this chapter.



Disabling Recent Documents History !


Windows XP includes a feature that keeps track of all recent documents you have opened or used. The idea is that you can select Start/Recent Documents History and quickly reopen any document you have recently used. I use many documents each day and never use the feature myself. In my opinion, I can keep up with what I want to use without Windows XP doing it for me.
The bad thing about Recent Documents History is that Windows XP has to calculate what should be put there each time you boot Windows, which can slow things down. So, if you never use the Recent Documents History, it's a good idea to disable it. Here's how:
1. Open the Registry Editor (select Start/Run, type regedit, and click OK).
2. Navigate to HKEY_CURRENT_USER\Software\Mcft\Windows\ CurrentVersion\Policies\Explorer.
3. Create a NoRecentDocsHistory D_WORD key. Double-click the value to open it once it is created.
4. Set the Data Value to 1 to enable the restriction.
5. Click OK and close the Registry Editor. You'll need to restart the computer for the change to take effect.



Disabling the Boot Logo !


You can remove the boot logo that appears when you start Windows XP. This little tweak probably shaves only a few seconds off your boot time but seconds count if you are serious about trying to get Windows XP up and running as quickly as possible. The only negative is that if you remove the boot logo, you will also not see any boot messages, such as check disk. (But if you are not having problems with your computer, this isn't such a big deal.)
To remove the boot logo, follow these steps:
1. Select Start/Run, type msconfig, and click OK.
2. In the System Configuration Utility, click the BOOT.INI tab.
3. On the BOOT.INI tab, click the NOGUIBOOT check box option. Click OK.



Removing Unwanted Fonts !


One trick that increases your boot time a bit is to lose any fonts in the Fonts folder in Control Panel that you never use. The more fonts you have, the more processing Windows XP has to do to prep all of those fonts for use. You must be a bit careful here to not remove fonts that you might want, but there is a good chance that you can live without many of them. For instance, you may have foreign language fonts and other symbol fonts (such as Wingdings) that you never use.
To delete unneeded fonts, follow these steps:
1. Open the Fonts folder in Control Panel.
2. Select Edit/Select All and then Edit/Copy.
3. Create a new folder on your desktop, open it, and select Edit/Paste.
4. In this new folder, delete any of the fonts you do not want.
5. Return to the Fonts folder in Control Panel. Right-click the selected fonts and click Delete.
6. Go back to your new desktop folder and click Edit/Select All.
7. Return to your Fonts folder and click Edit/Paste. You now have only the desired fonts in the Fonts folder.



Tip:


You can directly delete fonts from the Fonts folder without creating the secondary folder. However, I recommend the preceding steps to help ensure that you do not make a mistake in the deletion process.



Stopping Remote Assistance and Remote Desktop Sharing !


In Windows XP Professional, you have two remote networking features called Remote Assistance and Remote Desktop Sharing. These remote networking features are very helpful in a variety of situations but if you don't use them, it is good idea to disable them to save boot time. You can always enable them later if you want to use them.
Note:
If you are interested in using Remote Desktop or Remote Assistance, see my book Windows XP for Power Users: Power Pack published by John Wiley & Sons.
1. Open the Start menu, right-click My Computer, and choose Properties.
2. Click the Remote Tab.
3. Clear both check boxes to disable Remote Assistance and Remote Desktop.



Speeding Up the Dual-Boot Timeout !


If you dual-boot your computer with Windows XP and another operating system, you see an operating system selection menu on startup. If you typically boot into Windows XP and not the other operating system, you can speed up the dual-boot timeout value so that you do not wait so long for the boot process to select your default operating system and continue with the boot process. The default timeout value is 30 seconds but you can change this setting to 10. This gives you enough time to select the alternate operating system if you want but also speeds up the boot process. You can skip this section if you do not use a dual-boot configuration.
Follow these steps:
1. Locate the boot.ini file on your computer. It is a hidden file by default; mine is located in C:\boot.ini.
2. Open the file with Notepad (which is what opens it by default).
3. Change the Timeout value to 10 (see Figure 4-11).
4. Select File/Save and close Notepad.



Speeding Up Your PPPoE Connection !


If you use a Point-to-Point Protocol connection over Ethernet (PPPoE), you may notice a delay in using the PPPoE connection after startup. By default, there is a 120 second delay but you can stop this behavior by manually configuring an IP address for the network adapter card. If you do not use a PPPoE connection, you can skip this section.
1. Select Start/Connect to/Show All Connections.
2. Open the TCP/IP properties for your LAN network interface card.
3. Manually set the IP address on the TCP/IP properties to an appropriate IP address and subnet mask for your network.



Reducing the Wait Time


When you start to shut down Windows XP, it has to quit, or "kill," any live applications or processes that are currently running. So close all applications first. However, some applications and processes are always running in the background. You can reduce the amount of time that Windows XP waits for those applications and processes to close before Windows XP kills them. Edit three different Registry settings to change this:
1. Open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop. Select WaitToKillAppTimeout and set the value to 1000.
3. Select the HungAppTimeout value and set it to 1000 as well.
4. Navigate to HKEY_USERS\.DEFAULT\Control Panel\Desktop. Set the WaitToKillAppTimeout and set the value to 1000. Select the HungAppTimeout \newline value and set it to 1000 as well.
5. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control. Select the WaitToKillServiceTimeout value and set it to 1000.
6. Close the Registry Editor.


Automatically Killing Tasks on Shutdown !


You know the drill. You start to shut down the computer, you wait a few moments, and then you see a dialog box asking if you want to kill an application or service that is running. Instead of prompting you, you can make Windows XP take care of the kill task automatically. Here's how:
1. Open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop.
3. Highlight the value AutoEndTasks and change the value to 1.
4. Close the Registry Editor.

GOOGLE TALK SECRETS

GOOGLE TALK SECRETS

HOW TO Use multiple identities on Google Talk

Want to run Google Talk with multiple Gmail identities? If you have several Google Gmail accounts you also may want to run multiple instances of Google Talk This is especially important for families that share a single PC. Nothing worse than a family member signing you out so they can sign in under their own account!
Basically, to have "Google Polygamy" you need to run Google Talk with the following switch: /nomutex
Step 1: Right-click on the desktop
Step 2: Select New
Step 3: Select Shortcut
Step 4: Paste this into the text box:
"c:\program files\google\google talk\googletalk.exe" /nomutex
Step 5: Click Next and choose a shortcut name such as Google Talk1, Google Talk2, or something related to your Gmail account for easy remembering which account is which.
Step 6: Click OK a few times.

HOW TO Use Google Talk via a Web Browser

You want to use Google Talk anywhere ? Follow these guidelines :)
Step 1: Opens your favorite web browser at the following address :
http://www.webjabber.net:8080/jim/
Step 2: Follow the instructions of the Page.
Step 3: You can talk with your friends
Google's Secret Command-Line Parameters
There are a few secret parameters you can add to Google Talk and make it function differently.
The most important, I think, is /nomutex, which allows you to run more than one instance of GT. Here are the others:
/nomutex: allows you to open more than one instance of Google Talk
/autostart: when Google Talk is run with this parameter, it will check the registry settings to see if it needs to be started or not. If the "Start automatically with Windows" option is unchecked, it won't start.
/forcestart: same as /autostart, but forces it to start no matter what option was set.
/S upgrade: Used when upgrading Google Talk
/register: registers Google Talk in the registry, includig the GMail Compose method.
/checkupdate: check for newer versions
/plaintextauth: uses plain authentication mechanism instead then Google's GAIA mechanism. Used for testing the plain method on Google's servers.
/nogaiaauth: disables GAIA authentication method. The same as above.
/factoryreset: set settings back to default.
/gaiaserver servername.com: uses a different GAIA server to connect to Google Talk. Used for debug purposes only, there are no other known GAIA servers.
/mailto email@host.com: send an email with Gmail
/diag: start Google Talk in diagnostic mode
/log: probably has something to do with the diagnostic logging
/unregister: ?
/embedding: ?
To add these, open up your GT shortcut, and where it says "Target:" add one or more of these inside the quotations, but after the .exe part.


How To do Conference Calls

What you need to do to have conference calls:

Open up a copy of Google Talk on all computers with which you wish to conference.

After one copy is opened make a new shortcut for Google Talk but at the end of it add /nomutex.

If you installed it to the default folder then your shortcut should read "C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex.

Open 2nd instances of the software on every user's computer.

After this start a chain: User 1 should connect on one instance to user 2. User 2 will connect on his second instance to user 3. User 3 will connect using his second instance back to user 1. With this chain everyone is connected to everyone.


Nickname & Status Message

You can't change your nickname in a way that other people will see it change. Every nickname in the Google Talk contact list is the part that is before @gmail.com (only the alphabetical characters are used) or the name you chosen for your GMail account.

To change the nickname need to go to your Gmail account and change the name there. Choose Settings, Accounts, and then Edit info. Click on the second radio button, and enter your custom name. As a result all of your emails will have that nick as well, there is no way to seperate the two. You can add a website in your custom message, it will be click-able when someone opens a conversation window with you.

Contacts

You don't need to say Yes or No when someone wants to add you as a friend; you can simply ignore it, the request will go away. (On the other hand, someone with whom you chat often will automatically turn to be your friend, unless you disable this).
The Gmail account 'user@gmail.com' can't be invited as your friend.

Play Music

It's possible to broadcast music, MP3, etc.. through Google Talk.
Unplug your microphone. Double click on the speaker icon in the lower right corner. This will open up "Volume Control". Select "Options" and then "Properties". Then check the button next to "Recording" then click OK. You may also have to change your setting under Mixer Device. Now the Recording Control screen should be up. On my computer I selected "Wave Out Mix". Click on the green phone in Google Talk and call your friend.
