Hi,

Yes, the function of FTP protocol is to transfer files. Of course, the computer/server that hosts the files must first set up the FTP server.

SO FOR EXAMPLE, IF I HAVE A FTP SERVER AND A FTP CLIENT, THE FTP CLIENT IS GOING TO TRANSFER THE FILES THAT ARE HOSTED ON THE FTP SERVER BACK TO THE FTP CLIENT RIGHT.
Expert:  Viet - Network Tech replied 1 year ago.
Yes, you got it exactly right. Thank you.
Customer: replied 1 year ago.
My question is when you use the FTP client to connect to the FTP Server, is the FTP client going to initiate a connection to the FTP server using port 21.
After the control connection is established for the FTP Server, is the ftp protocol going to open a second connection for port 20 to allow files to be transfered from the FTP client to the FTP Server.
Expert:  Viet - Network Tech replied 1 year ago.
Yes, ftp uses two ports: Port 21 is for the command or control, and port 20 is for transferring the data. Thank you.
Customer: replied 1 year ago.
So basicly the ftp client is going to opean a connection to the ftp server using port 21 and after the control connection is established for the ftp server, then it is going to use port 20 to opean a connection to the ftp client to allow the transfer of data right.
Expert:  Viet - Network Tech replied 1 year ago.
Yes, that is correct. Port 21 is for opening a connection session, and port 20 is for transferring data. Thank you
