FTP (File Transfer 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>
Types of FTP

Active FTP
Passive FTP
Other Protocols


TCP (Transmission Control Protocol)
HTTP (Hypertext Transfer Protocol)
POP (Post Office Protocol)
UDP (User Datagram Protocol)
IMAP (Internet Message Access Protocol)
Drawbacks 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 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 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.
Introduction
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 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.

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#.

It can be used to establish connection,
provide directory listing, delete files,
download files, upload files & make
directory.
