Though FTP is a straightforward facility to transfer files through the internet easily, without much fuss it is dependent on several factors that makes the process possible. First, you need a client software that can be installed for uploading and downloading, allowing your desktop to take on the same plane as the server that is handling the file distribution. The said “SERVER” may be a simple desktop too but is the so-called traffic light which tells clients, where the files are coming from and who the packets of data are for. (more…)
Archive for the ‘FTP History’
FTP protocol or file transfer over the network took root in 1980. This is when the first RFC for FTP protocol was ever published. The functions of FTP include uploading, downloading and deleting files, creating and deleting directories, and reading directory contents. FTP has certain disadvantages which makes it harder to use although it is very popular. Major drawbacks would be the lack of uniform format for directory listing – though not supported by some servers; this problem was partially solved by introducing MLST command. Another disadvantage would be the presence of secondary connection (DATA connection). FTPS is the secured version of FTP.
Another security standard has grown in UNIX systems. It’s the SSH family of protocols. Securing remote shell access to UNIX systems is the primary function of SSH. Later, SSH was already extended with file transfer protocol – SCP (in SSH 1) SFTP (in SSH 2). The version 1 of the SSH protocol is already insecure, outdated, and generally not recommended for use. After a while, SCP is not used anymore and SFTP already gained popularity everyday. The abbreviation of “SFTP” is often mistakenly used to relate to a Secure FTP. However, these people often mean “FTPS” – which is the real secured FTP.
