The well-known port of the control connection is TCP port 21. However, the best way to prevent access to sensitive files is not to put them on an FTP server with public access in the first place. Of course, this does not stop people from trying to access files they had no business seeing, but if the file system permissions are set up correctly (or at all), FTP is highly secure. Private IDs can be combined with anonymous FTP to protect certain areas of the file system while allowing public access to others. Of course, there are file areas on the FTP server that should only be accessed by authenticated users of the remote system.

The point behind anonymous FTP is that users are not required to have a valid user ID or password on the remote system in order to be able to access files in some directories. In many cases, the FTP server will accept a similar term such as guest or visitor.

Some do not allow more creative substitutes for an email address, and many FTP servers check for things such as the presence of dots and the at sign ( to try to enforce some semblance of honesty. Anonymous FTP implementations used to allow users to simply press Enter and leave the anonymous password field blank, but many FTP implementations now demand at least something at the password prompt. The user is supposed to use their email address as a password, a primitive auditing measure. The FTP server requires a log-in from the user, and in some cases servers allow a special log-in for anonymous FTP. The number of simultaneous clients an FTP server can accept varies and is usually a configurable parameter, but limits well above 100 are not unusual. That is, an FTP server process (such as ftpd) is listening for clients’ connection requests. The FTP control connection is set up in the usual client–server fashion. But RFC 959 simply notes that the control connection essentially uses the remote access telnet protocol, leading one to believe that the developers wanted to use something already existing. One explanation is that there is always an available control connection to quickly countermand actions that have unintended or unexpected results. One major difference between FTP and almost every other application is the fact that FTP employs not one but two ports between client and server. Walter Goralski, in The Illustrated Network (Second Edition), 2017 FTP BasicsįTP was defined in RFC 959 and updated in RFC 2228, RFC 2640, RFC 2773, RFC 3659 and several others (be careful of the errata).
