Servidor Ftp

[[eduarcol]]

Hola a todos, necesito instalar un servidor FTP, alguien conoce alguno, que me recomiendan??, experiencias??

[jhonny]

No se como sea la versión Server del FileZilla, supongo que debe ser muy buena, ademas de todo es gratuito.

Pero una vez tuve la oportunidad de usar un Trial del ServU y la impresion que me dio es que es genial, en http://www.principiantes.info/servid...rvu_afondo.php hay una pequeñisima introducción de su utilización.

yo lo tengo montado en un Proyecto que recien termine esto con mucho mas.
tienen que hacer el enlace como lo muestra la uses de esta unit

[[eduarcol]]

esta interesante, pero lo que necesito es un servidor para administrar unas descargas
