Disabling the FTP Server For Plesk 8.x and 9.x

The FTP server can be used as an entry point for a server compromise if it is not regulary updated of if the FTP users are using non-strong passwords. One way to combat this is to disable the FTP server access completely.

Log into the Linux server by using SSH / Shell.  Once you have logged in you will need to edit the "ftp_psa" file, which is located at "/etc/xinetd.d/ftp_psa.

To do this you will need to type the following;

"vi /etc/xinetd.d/ftp_psa

Now that the file is open, you will need to change disable the FTP server by editing the line that disables or enables the FTP server.

Change  disable = no to disable = yes
      
Be sure to save the file and then close it.

Now you have to restart the service that runs the FTP server, which would be the Xinetd service. T do this type the following command;

service xinetd restart.

The server will restart and the ftp server will now be disabled.
