how to deny user to use ftp to access system
 

I use vsftp server , I want to deny user to use ftp to access the system , could suggest what can I do ? thx

There are several alternatives. In a nutshell:

- If you don't want any user to use FTP: Stop the FTP service.
- If you only want certain users to log-in: Disable anonymous connection and specify the list of users that you want to allow to connect.
- If you want to restrict what users can see: Grant specific rights to the ftp folders

thx reply ,

I think the below alternative is suit for me , could suggest how to do it ? thx

Add the usernames of the users you don't want to use ftp in /etc/ftpusers

thx reply , instead of add all users to the /etc/ftpusers ( because we have many users) , can I deny the user by group ? thx
