___________________________________________________________

lo primero que debemos hacer es instalar el paquete proftpd:
luego crearle una contraseña al usuario ftp:    (passwd ftp)
luego modificamos el archivo proftpd.conf ubicado en etc/proftpd/
y habilitamos la parte del anonimo.. por ejemplo
*********************************************************************************************************
#

# To prevent DoS attacks, set the maximum number of child processes
# to 30.  If you need to allow more than 30 concurrent connections
