Bandwidth can be defined as the amount of data that can be Transferred from one point to another in a given period time or in other words a unit time is called Bandwidth.There are few types of Bandwidth available such as Metered and Unmetered Bandwidth.In Metered Bandwidth,Bandwidth is managed by web space provider and which has a certain limit according to the plan of the hosted website.There are some systems and soft wares available which help the web space provider to manage the Bandwidth of the particular website.Unmetered Bandwidth is exactly opposite to Metered Bandwidth.

If  you are looking for such a web hosting service,kindly take a look at eukhost, one of the Best Web Hosting service provider in the UK.There are various web hosting packages that should be suitable for your website/s at affordable price.

Usually it becomes difficult to handle HTTP flood attacks,the reason being the lack of way to identify legitimate packets from the ones which are sent by the hacker,hence it is difficult to tackle such situation. The servers TCP/IP stack isn’t the only target,the prime target of HTTP flood ddos attack is the web server too that runs on it thus it results in more serious attack which is not easy to handle and your server may crash down resulting in its inaccessibility.

Though we say that it is difficult to tackle such attacks,but it isn’t impossible.There exists a solution for handling such HTTP flood ddos attack.

There exists an advanced technique known as “Tarpitting” which is an efficient counter acting method to fight against such attacks.Incase you are using a Linux based server, you can enable Tarpitting using the below command :

iptables -A INPUT -s x.x.x.x -p tcp -j TARPIT

Tarpitting automatically sets connections window size to few bytes once established successfully. According to TCP/IP protocol design, the connecting device will initially only send as much data to target as it takes to fill the window until the server responds. Just incase the connecting device does not receive responses, it will repeatedly start sending packets for longer period of time.
Here plays the actual role of ” tarpitting “,it won’t respond back to the packets, hence protecting your server from getting unwanted HTTP requests.

Inorder to avoid such attacks and threats,it is important to choose the Best Web Hosting services from a reputed web hosting company.No matter if you have a small business web hosting package or a Dedicated server hosting account,if you are using the services of a reliable web hosting provider,their technical expertise can help you counter act such attacks with minimum waste of time resulting in the least loss to your server.

Server 2000 you had to use Enterprise Edition to  provide Web Access with a Front-end

Server.But it is a different case with the  Exchange Server 2003.With the  Exchange

Server 2003 it is possible for you to use Standard Edition or Enterprise Edition of Exchange

Server to provide Web Access with a Front-end Server.Considering a network infrastructure

is very important before thinking of implementing a Front-end Dedicated Server.You have to look for

all these.What kind of firewall(s) do you have? Do you have a DMZ (also known as perimeter

network)?Are you using an ISA Server 2000 or any other application layer firewall? Especially

using ISA Server 2000 you have some tricky functions providing a good way to securely

configure OWA Access over the ISA Server.

Preparing Exchange server 2003 for Outlook Web Access

Every user has HTTP as an allowed protocol and the Exchange server 20003 you have

will generally behave like a Backend Server. If you do not want some of your users from

accessing their mailbox using Outlook Web Access then only you have to configure on

Backend Dedicated Servers or else it is not necessary. Via Active Directory Users and Computers

in the user properties this can be done quite easily.

Figure A :- Enabling Outlook Web Access for a user

Now installing and configuring your Frontend Server will be the next task for you.

Installing it as a second Exchange Server in your organization is the easiest way to do this.

After that we should enable it to act as a Front-end Server.

In the properties of your Exchange Server in Exchange System Manager this can be

generally done.

Figure B :- Configuring a Frontend Server

Server changes from using the DAVEx process (to act as Backend Server) to the

ExProx process (acting as Frontend Server) If we choose this configuration.

To make the changes take effect rebooting the server is the next step.

To make the Frontend Server a genuine Frontend we should follow the following steps

and disable all unnecessary services.You must have the following services running

on your Frontend Server , every other service may be stopped without any trouble.

• HTTP-Service
• SMTP-Service
• Exchange System Attendant
• Exchange Routing Engine

As there should not be any public folders or mailboxes on your Frontend Server

you do not need to run the Exchange Information Store.Dismount and delete all

databases on your server and then disable the Exchange Information Store Service

will be the best option for you.We now have to configure the appropriate ports on

the firewall(s) to make our server run that is after you have successfully placed this

server in the perimeter network (also known as DMZ).

We have to open the following ports on the intranet firewall (which connects the DMZ

and the internal network).

• For Exchange Communication:
  • Port 80 for HTTP
  • Port 691 for Link State Algorithm routing protocol
• For Active Directory communication:
  • Port 389 for LDAP (TCP and UDP)
  • Port 3268 for Global Catalog Server LDAP (TCP)
  • Port 88 for Kerberos Authentication (TCP and UDP)

Important :- You should now configure the DSAccess service for perimeter networks

on your Frontend Server. At first you should disable the check for available disk

space at netlogon by using RPC. This can be done by changing the following registry

key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeDSAccess
Registry Value: DisableNetlogonCheck
Value Type: REG_DWORD
Value Data: 1

In addition to this you should prevent DSAccess from pinging domain controllers.

This can be done by creating the following key on your Frontend Server:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeDSAccess
Registry Value: LdapKeepAliveSecs
Value Type: REG_DWORD
Value Data: 0

Then you should configure your Exchange Frontend Server to connect to the DC and

GC you want by editing the server properties in Exchange System Manager.

• For DNS communication:
  • Port 53 for DNS (TCP and UDP)
• For RPC communication:
  • Port 135 – RPC endpoint mapper (TCP)
  • Ports 1024 and higher for RPC services

Important :- You can limit RPCs across the firewall by editing the registry of

all your DCs. You should now change the registry setting of the following key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters
Registry Value: TCP/IP Port
Value Type: REG_DWORD
Value Data: (available port)

If you are using IPSec between Frontend- and Backend Servers you have to open:

• Port 500 for IKE (UDP)
• Port 51 for Authentication Header (AH)
• Port 50 for Encapsulation Protocol (ESP)

By configuring the Network Load Balancing Service (NBL) to act as a virtual cluster

you can provide high availability for your Frontend Server.Users connect to a running

Frontend Server will be made sure by NLB.Then every user connecting to Outlook Web Access

will connect to the virtual cluster and will then be redirected to one of your Frontend

Server nodes.

Implementing Security for Outlook Web Access

You may be concerned about security matters If you have successfully implemented your

Exchange Front-End Server constellation for providing Outlook Web Access for your users.

HTTP connectivity is not very secure and authentication information is always on the net

as clear text.In addition to this, Outlook Web Access authentication is generally session based.

This means you remain logged in if you do not logoff and close your browser.It becomes quite

easy for other users to read and send emails in the name of a company user in public web

access areas where users are unable to close the browser window.

Providing a secure HTTPS connection with an SSL server certificate is quite easy to implement.

The most interesting decision is whether to buy web server certificate from a well-known

trust center like Verisign or anyone else or to use a web server certificate from an internal

certificate authority.This certificate must then be installed on your Outlook Web Access server.

Figure C :- Installing a Web Server Certificate on an OWA Box

Now you can choose between a non-secure or a secure channel.Just check the appropriate box and

it runs if you would require 128-bit encryption.Some countries have laws that only allow 40-bit

encryption (e.g. France) so it is better that you do not forget that.You can make your OWA

connections more secure with a new feature in Exchange Server 2003.“Form-based Authentication”

this is the feature and it means you can configure a cookie timed-out session connection.

As shown in the following picture below this can be quite easily implemented.

Figure D :- Enabling Form-based Authentication

You have a default setting of 10 minutes as the timeout value for a client session

after you enable this feature.Ater this you must re-logon to get a new cookie and

new Outlook Web Access access.

Important :- You can change the default timeout by changing the following registry setting:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\OWA
Registry Value: PublicClientTimeout
Value Type: REG_DWORD
Value Data: (possible setting decimal)

and

Registry Value: TrustedClientTimeout
Value Type: REG_DWORD
Value Data: (possible setting decimal)

On both registry values the possible settings will vary from 1 – 4320 (minutes).

You have to restart your W3SVC service after changing these settings you have to restart

your W3SVC service.

With the setting of compression you have the possibility of speeding up your connections,

if you can make sure that your OWA clients are aware of the following requirements:

• Windows 2000 or later
• Internet Explorer 6.0 with the cumulative of November 2002 or Netscape Navigator 6.0 or higher.

Bandwidth can be defined as the amount of data that can be Transferred from one point to another in a given period time or in other words a unit time is called Bandwidth.Bandwidth is provided by the web hosting company and is according to the server and plan selected by the client.Nowadays, many of the web hosting companies offer Unmetered Bandwidth.”Unmetered” Bandwidth is the Bandwidth used is not metered and it does not include any usage or overage charges. Unmetered Bandwidth cannot be called as unlimited, you will get a better idea about this with an example that 10Mbps connection gives a maximum transfer of roughly 3000 GB per month.The ISP provider also has a role in this as the speed of the internet connection is very important.

encryption, this way, your data is encapsulated and secure in transit – this creates the

‘virtual’ tunnel.A method of connecting to a private network by a public network is

called a VPN (Example:-internet).An internet connection in a company is common.

The internet connection we use in home is a common connection too.An encrypted

tunnel between themcan be created with both of them and pass traffic,

safely – securely.

you will have to use encryption if you want to create a VPN connection to

make sure that others cannot intercept the data in transit while traversing

the Internet.Tunneling Protocol (PPTP) or Layer Two Tunneling Protocol (L2TP)

are used Point-to-Point by Windows XP which provides a certain level of

security.simply because they create that virtual tunnel just discussed, by

applying encryption they are both considered tunneling protocols.

Configuration :-

To configure VPN you only need what comes with the Operating System itself

and it is built in.Just follow the steps:-

1)Confirm that the connection to the Internet is correctly configured on the

computer that is running Windows XP.

• You can try to browse the internet
• Ping a known host on the Internet, like yahoo.com, something that isn’t blocking ICMP

2)Click start and then click Control Panel.

3)In Control Panel, double click Network Connections

4)Click Create a new connection in the Network Tasks task pad

5)click Next,In the Network Connection Wizard.

6)Click Connect to the network at my workplace, and then click Next.

7)Click Virtual Private Network connection, and then click Next.

8)If you are prompted, you need to select whether you will use a dialup connection

or if you have a dedicated connection to the Internet either via Cable, DSL, T1,

Satellite, etc.  Click Next.

9)Type a host name, IP or any other description you would like to appear in the

Network Connections area. You can change this later if you want. Click Next.

10)Type the host name or the Internet Protocol (IP) address of the computer that

you want to connect to, and then click Next.

11)You may be asked if you want to use a Smart Card or not.

12)You are just about done, the rest of the screens just verify your connection, click Next.

13)Click to select the Add a shortcut to this connection to my desktop check box

if you want one, if not, then leave it unchecked and click finish.

14)You are now done making your connection, but by default, it may try to connect.

You can either try the connection now if you know its valid, if not, then just close it

down for now.

15)In the Network Connections window, right-click the new connection and select properties.

Let’s take a look at how you can customize this connection before it’s used.

16)The first tab you will see if the General Tab. This only covers the name of the connection,

which you can also rename from the Network Connection dialog box by right clicking the

connection and selecting to rename it. You can also configure a First connect, which means

that Windows can connect the public network (like the Internet) before starting to attempt

the ‘VPN’ connection. This is a perfect example as to when you would have configured

the dialup connection; this would have been the first thing that you would have to do.

It’s simple, you have to be connected to the Internet first before you can encrypt and

send data over it. This setting makes sure that this is a reality for you.

17)The next tab is the Options Tab. It is The Options tab has a lot you can configure

in it. For one, you have the option to connect to a Windows Domain, if you select this

check box (unchecked by default), then your VPN client will request Windows logon

domain information while starting to work up the VPN connection. Also, you have

options here for redialing. Redial attempts are configured here if you are using a dial

up connection to get to the Internet. It is very handy to redial if the line is dropped as

dropped lines are very common.

18)The next tab is the Security Tab. This is where you would configure basic

security for the VPN client. This is where you would set any advanced IPSec

configurations other security protocols as well as requiring encryption and

credentials.

19)The next tab is the Networking Tab. This is where you can select what

networking items are used by this VPN connection.

20)The Last tab is the Advanced Tab. This is where you can configure options

for configuring a firewall, and/or sharing.

Connecting to corporate

Now that you have your XP VPN client all set up and ready, the next step

is to attempt a connection to the Remote Access or VPN server set up at

the corporate office. To use the connection follow these simple steps.

To open the client again, go back to the Network Connections dialog box.

1)One you are in the Network Connection dialog box, double-click, or right

click and select ‘Connect’ from the menu – this will initiate the connection

to the corporate office.

2)Type your user name and password, and then click Connect. Properties

bring you back to what we just discussed in this article, all the global settings

for the VPN client you are using.

3)To disconnect from a VPN connection, right-click the icon for the connection,

and then click “Disconnect”.

You can use the above steps to install VPN on Dedicated servers as well.

on the internet is done by VoIP. Accelerating hardware might be used by  VoIP for this purpose

and can also be used in a Pc environment.Now we will see how VoIP is setup.

Setup :

1) Simple communication :- IP to IP

       X (Sound card)   -  -  -    Y (Sound card)

        192.168.1.2     -  -  -     192.168.1.3

192.168.1.2 calls 192.168.1.3 and viceversa.

X and Y should have :-

1.Properly installed and configured application like Microsoft Netmeeting,
  Internet Switchboard,Openh323 (under Windows environment) or Ohphone,
  Gnomemeeting (under Linux).

2.A kind of TCP/IP interface or a network card to talk to each other.

  In this kind of view X can make a H323 call to Y (if Y has server side
  application active)using Y IP address. Then Y can answer to it if it wants.
  After accepting call, VoIP data packets start to flow.

2)Using names

NetBIOS name can be used instead of an IP address Under Microsoft Windows :-

          X            -  -  -             Y 

     192.168.1.2       -  -  -        192.168.1.3

         Win           -  -  -            Jane

                    Win calls Jane

Win call request to Jane is converted to IP calling by the NetBIOS protocol.
This is the reason that it possible.

2 Examples given above are very easy to implement but aren't scalable.

In a more big view such as Internet it is impossible to use direct calling cause,
usually,the callers don't know the destination IP address. Furthermore NetBIOS
naming feature cannot work cause it uses broadcast messages, which typically
don't pass ISP routers .

You can also use DNS to solve name in IP address: for example you can call
''box.domain.com''.

3)Internet calling using a WINS server

The NetBIOS name calling idea can be implemented also in a Internet environment,
using a WINS server: NetBIOS clients can be configured to use a WINS server
to resolve names.

If WINS server is the same used by the PCs then it is possible for them to make
direct calling between them.

X (WINS Server is G) - - - - I  - - - -  Y (WINS Server is G)
                             N
                             T
                             E  - - - - -   G (WINS Server)
E (WINS Server is G) - - - - R
                             N
                             E  - - - -  F (WINS Server is G)
                             T

                   Internet communication

X,Y,E,F are different subnets ,but they can call each other in a NetBIOS name
calling fashion.The need is that all are using G as WINS Server.

Note: WINS server doesn't have very high performance because it uses NetBIOS
feature and should only be used for joining few subnets.

4)ILS Server

ILS is a kind of server which allows you to solve your name during an H323 calling:
when you start VoIP application you first register to ILS server using a name,
then everyone will be able to see you.

5)The masquering:A big problem.

A problem of few IPs is commonly solved using the so called masquering
(also NAT, network address translation): there is only 1 IP public address
(that Internet can directly "see"),the others machines are "masqueraded" using
all this IP.

           X  - - -

           Y  - - -   Router with NAT  - - -  Internet

           E  - - -

                       This doesn't work

In the example X,Y and E can navigate, pinging, using mail and news services
with Internet people, but they CANNOT make a VoIP call.This because H323 protocol
send IP address at application level,so the answer will never arrive to source
(that is using a private IP address).

Solutions:

• there is a Linux module that modifies H323 packets avoiding this problem.
• You can download the module here. To install it you have to copy it to source
• directory specified, modify Makefile and go compiling and installing module with
• “modprobe ip_masq_h323″. Unfortunately this module cannot work with ohphone
• software at this moment (don’t know why).

           X  - - -   Router with NAT 

           Y  - - -         +           - - -  Internet

           E  - - -  ip_masq_h323 module

                         This works

• There is a application program that also solves this problem: 

           X  - - -   

           Y  - - -    PhonePatch   - - -  Internet

           E  - - -  

                         This works

6)Open Source applications

Ohphone Sintax

Sintax is:

“ohphone -l|–listen [options]”

“ohphone [options]… address”

• “-l”, listen to standard port (1720)
• “address”, mean that we don’t wait for a call, but we connect to “address” host
• “-n”, “–no-gatekeeper”, this is ok if we haven’t a gatekeeper
• “-q num”, “–quicknet num”, it uses Quicknet card, device /dev/phone(num)
• “-s device”, “–sound device”, it uses /dev/device sound device.
• “-j delay”, “–jitter delay”, it change delay buffer to “delay”.

Also, when you start ohphone, you can give command to the interpreter directly

(like decrease AEC, Automatic Echo Cancellation).

Gnomemeeting

Gnomemeeting is an application using GUI interface to make call using VoIP.

It is very simple to use and allows you to use ILS server, chat and other things.

7)Setting up a Gatekeeper

You can also experiment gatekeeper feature

Example

        (Terminal H323) X  - - -
                                 \
        (Terminal H323) Y  - -  - Z (Gatekeeper)
                                 /
        (Terminal H323) E  - - -  

                   Gatekeeper configuration

1. Hosts X,Y and E have gatekeeper setting to point to Z.
2. At start time each host tells Z own address and own name (also with aliases)
3. which could be used by a caller to reach it.
4. When a terminal asks Z for an host, Z answers with right IP address, so
5. communication can be established.

We have to notice that the Gatekeeper is able only to solve name in IP address, it

couldn’t join hosts that aren’t reachable each other (at IP level), in other words it couldn’t

act as a NAT router.

You can find gatekeeper code  here: open323 library is also required.

Program has only to be launch with -d (as daemon) or -x (execute) parameter.

In addition you can use a config file (.ini) you find here.

8)Setting up a Gateway

As we said, gateway is an entity that can join VoIP to PSTN lines allowing us to made

call from Internet to a classic telephone. So, in addition, we need a card that could manage

PSTN lines: Quicknet LineJack does it.

From open323 website we download:

1. driver for Linejack
2. PSTNGw application to create our gateway.

If executable doesn’t work you need to download source code and open323 library,

then install all in a home user directory.After that you only need to launch PSTNGw to

start your H323 gateway.

9)Compatibility Matrix

First Matrix refers to:

1. Software intercommunications (i.e. Netmeeting with SwitchBoard)
2. Software/Driver/Hardware talking (i.e. Netmeeting can use a PhoneJACK card).

PHP is actually Hypertext Preprocessor.PHP is a computer scripting language.PHP is a simple yet powerful language designed for creating HTML content.PHP is originally designed for producing dynamic web content as it is the best for the task.As there is no formal specification the main implementation of PHP is now produced by the PHP group and serves as the de facto standard for PHP. PHP was originally created by Rasmus Lerdorf in 1995.THe PHP is considered as a free software by the Free Software Foundation and PHP is released under the PHP license.PHP is a scripting language that is widely used and is a general language which is used for web development.Also ,it can be embedded into HTML .PHP is used in the web server as it takes in the PHP code and gives out the web pages as a result.Recently the PHP 5.2.6 was released on 1 may ,2008 which is considered to be the most recent major release of PHP.PHP is installed on more than 1 million web server and more than 20 million websites.PHP can be installed on most Dedicated servers and on almost every platform or operating system free of charge.

PHP can be used in three different ways :-

- Server side scripting

Dynamic web content was the reason that the PHP was designed and it is suitable for the task.You need a PHP parser and to generate HTML and to send the documents you require a web server.XML documents,Flash animations ,PDF files ,graphics and more were also generated by PHP and it lately became popular for this.

- Command – line scripting

Much like Perl,awk or the Unix shell PHP can also run scripts from the command line.You might use the command-line scripts for system administration tasks,such as backup and log parcing.

- Client-side GUI Applications

You can write full-blown,cross platform GUI Application in PHP by simply using PHP-GTK (http://gtk.php.net)

PHP’s principal focus is server-side scripting and it is originally designed for this pupose only.PHP is similar to Microsoft’s ASP.NET system ,Sun Microsystems’ Java Server Pages and mod_perl as these are also some of the other server-side scripting languages that provide dynamic content from a web server to a client and the PHP also does the same.Cake PHP, PRADO, Symfony and Zend Framework are some of the frameworks offering features similar to other web application frameworks that provide building blocks and a design structure to promote rapid application development (RAD).These are also attracted to PHP.The LAMP architecture has become popular in the web industry as a way of deploying web applications.PHP is commonly used as the P in this bundle alongside Linux, Apache and MySQL, although the P may also refer to Python or Perl. PHP was recorded as the most popular Apache module as in April 2007 over 20 million Internet domains were hosted on the PHP installed Dedicated servers. Significant websites such as the user-facing portion of Facebook and Wikipedia[mediawiki] are also written in PHP.

The World Wide Web has been growing day by day.There are many factors due to which the World Wide Web has been growing from a long time.One of the reason for the growth of the World Wide Web is the Apache web server.Apache web server which is the Apache HTTP server and it is commonly referred to Apache has played a very important role in the initial growth of the World Wide Web.Netscape Communications corporation web server which is now known as Sun Java System Web Server did not have any other alternative before the Apache web server was introduced.After the launch of the Apache web server ,Apache web server became the alternative not only to the Netscape Communications corporation web server but also became a big rival to the other Unix-based Dedicated servers as it is very good in terms of  performance and functionality.There are two reasons why the name of the project was chosen as Apache.One of them was to respect the native American Indian tribe as they were well known for their endurance and their warfare skills and the other reason was that the project’s roots were the set of patches to the codebase of NCSA HTTPd 1.3 – making it a “patchy” server although the latter theory is a lucky coincidence.The Apache Software Foundation has an open community under it’s auspices which has developed and maintained the Apache.Apache is characterized as free software and open source software and it is released under the Apache License.Apache is available for a wide variety of operating systems including Solaris ,Free BSD ,Mac OS X ,Linux ,TPF ,Microsoft Windows ,OS/2 ,Unix ,eComStation.Apache has been the most popular HTTP server on the World Wide Web since April 1996.Of all websites Apache served 49.12% in June 2008.

mod perl ,mod python ,TCL and PHP are supported by some common language interfaces.By using free scripts such as AWstats/W3Perl or Visitors.configurable error messages,DBMS-based authentication databases, and content negotiation are also featured by Apache.Apache is also supported by several graphical users interfaces (GUIs) which allow easier, more intuitive configuration of the server.Apache Dedicated servers the static content and even the dynamic web pages on the world wide web.Many web aplications are designed as per the expectation of the environment provided by Apache.Apache is the web server component of the popular LAMP web server application stack, alongside MySQL, and the PHP/Perl/Python programming languages.Apache is used to run some of the biggest websites in the world.A modified version of Apache is used to run Google’s search engine front end ,named Google web server (GWS).Wikimedia projects and wilipedia are also run on Apache Dedicated servers. These are the one of the most famous websites on the internet.The main competitor to Apache is none other than Microsoft Internet Information Services (IIS).Internet Information Services is trailed by Sun Microsystems’Sun Java System Web Server and a host of other applications such as Zeus Web Server.Apache 2.2.9 ,Apache 2.0.63 and Apache 1.3.41 versions.Apache 2.2.9
