tmt said:I'm reading a text that is saying that the standard port for ftp is 21.
Do both the client/host use port 21? And what is the port is already being used, does it go to a different port?
FTP Port 21 is the port used by the File Transfer Protocol (FTP) to establish a connection between a client and a host. Its purpose is to facilitate the transfer of files between the two devices.
Clients use FTP Port 21 to initiate a connection with a host and send commands for file transfer. Hosts, on the other hand, use this port to listen for incoming connections and respond to client commands.
Yes, there are several alternatives to using FTP Port 21 such as SSH File Transfer Protocol (SFTP), Secure Copy (SCP), and File Transfer Protocol over Secure Shell (FTPS). These protocols offer better security and encryption compared to FTP.
FTP Port 21 is a widely used and established protocol for file transfer. It is supported by most operating systems and devices, making it easy to use. It also allows for fast and efficient transfer of large files.
Yes, there are security concerns when using FTP Port 21 as it does not use encryption to protect file transfer. This means that sensitive information, such as login credentials, can be intercepted by hackers. It is recommended to use alternative protocols that offer encryption for secure file transfer.
