5 Μαρ 2024 · FTPS typically uses port 990 for control connections and port 989 for data connections under implicit security. However, FTPS can also use port 21 when operating under explicit security. Learn more about the difference between FTPS vs HTTPS for secure file transfers.
For the explicit option you only need ONE port: 22. For the implicit option you only need to have the firewall open for the control port: 8086 (which forwards internally to port 21 on your filezilla server).
FTPS (also known as FTP-SSL and FTP Secure) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and, formerly, the Secure Sockets Layer (SSL, which is now prohibited by RFC7568) cryptographic protocols.
20 Οκτ 2011 · FTPS; Port for secure FTP: Uses only port 22. Uses multiple port numbers; one for the command channel, and an additional port on the data channel for every file transfer request or directory listing request. Authenticating connections: Choice to use a user ID and password to connect to an SFTP server or to use SSH keys with or instead of passwords.
FTP needs two ports (one for sending and one for receiving) because it was originally designed to operate on top of Network Control Protocol (NCP), which was a simplex protocol that utilized two port addresses, establishing two connections, for two-way communications.
17 Σεπ 2021 · SFTP authenticates both the user and the server and uses port 22. Unlike FTP and FTPS, SFTP does not use separate command and data connections. Instead, both data and commands are transferred in specially formatted packets via a single connection.
How does FTP work? FTP is a client-server protocol that relies on two communications channels between the client and server: a command channel for controlling the conversation and a data channel for transmitting file content. A typical FTP transfer works in the following way:
