Did not getting what to do?

What meant by changes,changes done vsftpd.conf or anything else? in secure_transfer_command_line_client

The changes that you made in your conf file are to be added in this file.

In file secure_transfer_command_line_client in the secure_transfer directory with:

  1. First line: Did the files get transferred securely (yes/no)?
  2. Second line: If yes, detail any changes made. If not, explain why.

As @visargdesai mentioned, you need to detail what changes you have to vsftpd.conf file.
