FTP Control Channel, and ls command
While I was reading I found this link:
http://www.siliconvalleyccie.com/linux-hn/ftp-server.htm
Control Channel (command and response), TCP Port 21 and Data Channel, TCP Port 20
I just wondring if there is a typo in the link above , because he is saying :
Quote: | but any data sent back (such as "ls" directory lists or actual file data in either direction) will go over the data connection. |
Quote: Your client connects to the FTP server by establishing an FTP control connection to port 21 of the server. Your commands such as 'ls' and 'get' are sent over this connection.
|
I feel there is contradiction between the two quoted above , because "ls" is command which should be sent over Control Channel not Data Channel,,,Am I right ?
