FTP (File Transfer FTP (File Transfer Protocol)Protocol)• A standard network protocol• Used to copy a file from one host to

another• Built on a client-server architecture• Utilizes separate control and data

connections between the client and server

• FTP URL syntax is taking the form:ftp://[<user>[:<password>]@]<host>[:<port>]/<url-

path>

Other ProtocolsOther ProtocolsTCP (Transmission Control Protocol)HTTP (Hypertext Transfer Protocol)POP (Post Office Protocol)UDP (User Datagram Protocol)IMAP (Internet Message Access

Protocol)

Drawbacks of other ProtocolsDrawbacks of other Protocols

The disadvantages lie in the power when it comes to file uploading.

Also, a programmer needs to have the knowledge required to create the form in HTML, in order to upload the file in question.

A user cannot use a program to perform a mass upload to a server.

Downloads cannot be done on masses as well.

Current ScenarioCurrent Scenario• We need to install a client tool to

access data from an FTP server on every machine that we use.

• These tools have limited functionality when it comes to handling FTP server data.

• Multiple connections cannot be established using a single tool, you need to open multiple instances of the tool to access multiple accounts.

Problem StatementProblem Statement• Currently we need to install a client tool to access

data from an FTP server on every machine that we use. Also multiple connections cannot be established using a single tool, you need to open multiple instances of the tool to access multiple accounts. To overcome these limitations we have developed an innovative solution to handle these common problems. As an alternative to the client tool we have developed a web based interface to handle FTP server data which can be accessed from a simple web browser any where across the globe. Also the web interface provides a connection to multiple FTP servers simultaneously. Also our solution provides users to maintain multiple FTP accounts.

IntroductionIntroduction• Web Based FTP can be used to

upload, download, view, delete and maintain user accounts on a FTP server via a simple browser.

• Web Based FTP can handle multiple FTP connections simultaneously.

• Web Based FTP is a new innovation where in you take your FTP client tool to the web and can use it where ever you want.

Proposed SolutionProposed Solution• Developing a website that would be

able to connect to a FTP server and maintain data on it.

• Single sign on access to all your servers.

• Also provide connection to multiple FTP servers.

• Support all kinds of browser.• Maintain multiple FTP accounts.

Technical ImplementationTechnical Implementation• The Web Based FTP will be developed on

.NET platform.• .NET platform is developed by Microsoft.• .NET is language independent platform.• It supports 4 native and 21 third part

languages.• Native languages: C#, J#, VB, VC++.• Third Party languages: Perl, ruby on rails

etc.• Web Based FTP will be developed using

C#.

Hardware & Software Hardware & Software RequirementsRequirementso Hardware• Pentium IV or above Processor• 256 MB RAM• 20GB HDD• Access credentials of FTP server

o Software• Windows 2000/Windows XP/Windows Vista/ Windows 7• .NET Framework 3.5• Microsoft Visual Studio 2008• Web Browser

BenefitsBenefits• Can be accessed from anywhere

across the globe.• No need of installations.• Can manage multiple FTP accounts.• Single sign on access to your

account.• Any browser compatible.• Provides facilities to establish

connection, provide directory listing, delete files, download files, upload files & make directory.

FeaturesFeatures• Maintain user accounts• Establish Connection• Directory Listing• File Delete• Download Files• Upload Files• Make Directory

Future DevelopmentsFuture Developments• Enhancement to the website for

drag and drop facility to upload and download.

• Online Desktop type UI to give the users a rich feel to the website.

• Ability to read all the contents directly without the need for downloading.

ApplicationApplication• Online handling of FTP server.• Since its web-based it can eliminate

the need to install FTP client tools.• Simultaneous multiple FTP

connections.• It can be used to establish

connection, provide directory listing, delete files, download files, upload files & make directory.
