During the pandemic, Google delayed its plan to kill FTP, and now that things have settled to some degree, Google recently announced that it is going back for the kill with Chrome version 86, which deprecates the support once again, and will kill it for good in Chrome Mozilla announced similar plans for Firefox, citing security reasons and the age of the underlying code.
It is one of the oldest protocols the mainstream internet supports—it turns 50 next year—but those mainstream applications are about to leave it behind. Like telnet, FTP still has a few uses, but has lost prominence on the modern internet largely because of security concerns, with encrypted alternatives taking its place—in the case of FTP, SFTP, a file transfer protocol that operates over the Secure Shell protocol SSH , the protocol that has largely replaced telnet.
The reason for that comes down to its basic functionality. As Bhushan describes In his requests for comment paper , the biggest challenge of using telnet at the time was that every host was a little different. I tried to present a user-level protocol that will permit users and using programs to make indirect use of remote host computers. The protocol facilitates not only file system operations but also program execution in remote hosts. This is achieved by defining requests which are handled by cooperating processes.
The transaction sequence orientation provides greater assurance and would facilitate error control. The notion of data types is introduced to facilitate the interpretation, reconfiguration and storage of simple and limited forms of data at individual host sites. The protocol is readily extendible. These early applications became the fundamental building blocks of the modern internet and have been greatly improved on in the decades since.
Due to the limited capabilities of computing at the time, Bhushan noted that early on, email-style functionality was actually a part of FTP, allowing for messages and files to be distributed through the protocol in a more lightweight format—and for four years, FTP was technically email of sorts. Of course, Bhushan was not the only person to put his fingerprints on this fundamental early protocol, eventually moving outside of academia with a role at Xerox.
While there have been some modest updates since to keep with the times and add support for newer technologies, the version of the protocol we use today came about in , when Jon Postel and Joyce K.
Postel and Reynolds, among others, also worked on the domain-name system around this time. Given its age, FTP has many inherent weaknesses, many of which manifest themselves to this day. For example, transferring a file folder with a lot of tiny files is intensely inefficient with FTP, which does much better with large files as it limits the number of individual connections that are needed.
In many ways, because FTP was so early in the history of the internet, it came to define the shape of the many protocols that came after. A good way to think about it is to compare it to something that frequently improves by leaps and bounds over a few decades—say, basketball sneakers. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. It's priced very economically and you can read all of it in a convenient format without ads.
If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.
Or go to the Tools menu and select "Adblock Plus Preferences Then click "Add Filter Then just click OK. This work included both the design and implementation of the protocols that would implement internetworks, and also the creation of the first networking applications to allow users to perform different tasks.
