Until then, if there is at least one ftp user, incoming ftp stays. Also notice that restricting the sites that can come through FTP does not help security: each time you type your password into FTP, everybody with a sniffer (local at BNL or at the remote site) can see it, and ssh into your account. This works both ways- when you FTP out of BNL, your password at the remote site is exposed to sniffers. K.O. > > I cannot ftp to the machine (I believe).
