Citar ProFTPD: configurar limites

What if a site wished to allow only anonymous access? This would be configured using the LOGIN command group, as above:

<Limit LOGIN>
  DenyAll
</Limit>

<Anonymous ~ftp>
  <Limit LOGIN>
    AllowAll
  </Limit>
  ...
</Anonymous>

The <Limit> section outside of the <Anonymous> section denies logins to everyone. However, the <Anonymous> section has a <Limit> that allows everyone to login; anonymous logins are allowed, and non-anonymous logins are denied.

P.S. Você pode criar uma seção separada DisplayLogin sorry.msg outside <Anonymous> com o texto "sorry ftp server is only anonymous" no arquivo sorry.msg.
