FTP protocol is used daily by most businesses around the world. Our ETL Software makes it easy to automate FTP uploads and downloads.
Complete FTP Automation

The users can create and delete directories on the FTP server, delete files, move files and produce a list of files. Here is a basic example of FTP workflow.

Making Life Of End Users And Developers Easier

We are constantly working on making our software better. This dialogue is a fully functioning FTP client. It allows the users to see the files on the FTP server. But we did not stop there. The users can also download and upload files, create and delete remote directories.

What is FTP
File Transfer Protocol (FTP) is a standard network protocol used to copy a file from one host to another over a TCP/IP-based network, such as the Internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server applications which solves the problem of different end-host configurations (i.e. Operating System, file names). FTP is used with user-based password authentication or with anonymous user access.

How FTP works

A client makes a connection to the server on TCP port 21. This connection called the control connection, remains open for the duration of the session, with a second connection, called the data connection, on port 20 opened as required to transfer file data. The control connection is used to send administrative data (i.e. commands, identification, passwords). Commands are sent by the client over the control connection in ASCII and terminated by a carriage return and line feed. For example "RETR filename" would transfer the specified file from the server to the client. Due to this two-port structure, FTP is considered out-of-band, as opposed to an in-band protocol such as HTTP.

The server responds on the control connection with three-digit status codes in ASCII with an optional text message, for example, "200" (or "200 OK.") means that the last command was successful. The numbers represent the code number and the optional text represent explanations (i.e. <OK>) or needed parameters (i.e. <Need account for storing file>). A file transfer in progress over the data connection can be aborted using an interrupt message sent over the control connection.

FTP can be run in active mode or passive mode, which controls how the second connection is opened. In active mode, the client sends the server the IP address port number that the client will use for the data connection, and the server opens the connection. The passive mode was devised for use where the client is behind a firewall and unable to accept incoming TCP connections. The server sends the client an IP address and port number and the client opens the connection to the server.

Security consideration

FTP has no encryption tools meaning all transmissions are in clear text; usernames, passwords, FTP commands and transferred files can be read by anyone sniffing on the network. This is a problem common to many Internet protocol specifications written prior to the creation of SSL, such as HTTP, SMTP and Telnet. The common solution to this problem is to use either SFTP (SSH File Transfer Protocol) or FTPS (FTP over SSL), which adds SSL or TLS encryption to FTP.

Anonymous FTP

A host that provides an FTP service may additionally provide anonymous FTP access. Users typically log in to the service with an 'anonymous' account when prompted for a username. Although users are commonly asked to send their email address in lieu of a password, no verification is actually performed on the supplied data.
