Ever since computing earlier days, data exchange was an important factor. One of the most common methods used for this purpose is connection of one computer with the other. In general, HTTP protocol is used in this task for getting internet access that allows downloading and uploading of files. Another popular method is via the use of FTP that we are going to discuss in this article.
What is FTP?
File Transfer Protocol or FTP is the rule system used by networked computers for communicating with each other. This protocol is client-server one used for exchanging files over internet between computers. The files asked by client are provided to them by server. A simple DOS like command line interface could be used for working with the FTP. File download is also allowed by the browsers via FTP in which files of any kind could be exchanged that includes videos, music and documents. The fine tuned FTP serves best for large files.
With the help of FTP, it is also possible to remove directories, create them and list the files but authentication is required for the same using a password and username. Keys are not needed by FTP servers that are anonymous and in general, these are used for freely distributed open source software.
While HTTP still takes care of several transfers, the common behind the scene transfer still make use of FTP like website builders, banking etc. FTP is older than standard network protocol TCP/IP powering the internet and it preceded HTTP as well.
Transfer modes in FTP:
The FTP session could be initiated in either passive or active mode and is used for getting details about establishment of connection. In any of these cases, a connection is established by the client over TCP using a random port to FTP server port 21. The notes of incoming data are taken by client in active mode on port N from server. PORT N is the FTP command sent to the server so that it comes to know about it. A connection is then established by the server from port 20 to client and then begins data transferring.
When server receives PASV command from client then a passive connection is established. The server then sends port number and IP address used by client for initiating data connection and begins sending using privileged port. Since all connections are started by client, this mode is also termed as firewall friendly.
FTP security:
In the initial stage, certain security weaknesses were there in FTP and for addressing them, drafting of RFC 2228 took place. The vulnerabilities such as FTP bounce, brute force attacks, port stealing, username enumeration and spoofing were still identified by RFC 2577 authors. The fact that traffic is not encrypted by FTP led many of these to branch. Infact, the diffusion was in clear text and passwords, usernames, data and command were easily readable to anyone with the ability of doing packet capture on network. These problems could be circumvented with the use of FTPS since it was more secure.
Establishing Connection with FTP server:
Users could be allowed for establishing connection with FTP server using two approaches: first one is making it so as to make anonymous login possible for anyone. The other approach is assigning passwords and user names to people to allow them for using the same for logging in to server.
For establishing connection with FTP server, the two methods that are commonly used are using FTP client or with web browser. For connecting with browser to the FTP server, the hostname is prefixed using which connection is established with the statement ftp://protocol. Attempts are them made by it for establishing anonymous connections. In case password and username are required for establishing connection with the desired server then use the following format for this purpose: ftp://username:[email protected]
In case when both password and username is required for establishing the connection then it is recommended to avoid entering the password since the history of your browser show this up. In place of entering the password, you can follow the following format: ftp://username @ftp.somedomain.com, in this approach, you will be prompted by the browser for entering the password and there is no such risk in this case about the password being visible in history list.
Another way is making use of the FTP client that is specifically designed to connecting with the FTP servers. Such software are streamlined for speed and offer support to several advanced features such as automatic resume and are therefore considered as the best options available.
Process of Files Transfer:
Whether your connection with FTP server is via the FTP client or web browser, you will receive a documents and folders list having files that could be downloaded on the system. You can click on the desired file to download it while making use of web browser and you will be prompted to open or save it.
In case an FTP client is used, a files list is presented that could be downloaded. It is required to mention the location where downloads should be saved and then you can begin downloading the file by double clicking on it. FTP client could be closed when the downloading is done and then file could be assessed from its storage location.
After going through the details about FTP, its security and method of establishing connection with FTP, you might now be keen for knowing the FTP clients that are best in industry. So we will now discuss about the top 10 free FTP software or clients for easily completing the file transfer.
