Is FTP port TCP or UDP?

Is FTP port TCP or UDP?

FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a 'data' port and a 'command' port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port.

Is TCP same as FTP?

The Difference Between FTP and TCP FTP is a file transfer protocol, which means it is used to transfer files between a client and a server, whereas TCP is a communication protocol used to exchange data between networks. They come together when FTP sends data over a TCP/IP connection.

Does FTP require TCP?

FTP itself uses the TCP transport protocol exclusively, or in other words, it never uses UDP for its transport needs. Typically an application layer protocol will use one or the other. One notable exception to that is DNS or Domain Name System. FTP also is odd in the fact that it uses two ports to accomplish its task.

Is port 21 a UDP?

Side note: UDP port 21 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 21 makes possible the transmission of a datagram message from one computer to an application running in another computer.

What ports can I use for FTP?

port 21 The FTP protocol typically uses port 21 as its main means of communication. An FTP server will listen for client connections on port 21. FTP clients will then connect to the FTP server on port 21 and initiate a conversation. This main connection is called the Control Connection or Command Connection.

Which FTP port should I use?

port 21 The FTP port that you generally need to know about to make a standard, unencrypted, FTP connection is port 21. For this standard case, this is all someone using an FTP client needs to know.

What protocol uses both TCP and UDP?

• UDP (User Datagram Protocol) is anther commonly used protocol on the Internet. However, UDP is never used to send important data such as webpages, database information, etc; UDP is commonly used for streaming audio and video.

Which two TCP ports does FTP use?

• FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a 'data' port and a 'command' port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port.

Which service use both TCP and UDP ports?

• DNS and some other services uses both TCP and UDP the reason for using both protocols is very simple as UDP is a connection less protocol and it does not acknowledge so it is slightly faster then TCP DNS and some other Services work on both the TCP and UDP Protocols. TCP protocal is used for DNS Zone transfer between two DNS servers.

What ports are used by FTP?

• FTP uses network ports 20 and 21. Below are other ports that may be used by other types of FTP. BFTP uses port 152. FTP over TSL/ SSL uses ports 9. NI FTP uses port 47. RSFTP uses port 26. SFTP uses port 115.
