[ML] same speed. passive means that the client (and not the server) opens the data connection. advantageous for people sitting behind packet or nat firewalls. > - any (windows) tools not supporting it? [ML] this is an ftp client request. some ancient ftp servers may not support passive data connections, but I haven't seen one of those in a long while. I don't know whether the windows ftpd is incapable of passive mode. actually, if the passive mode default is implemented correctly, the client should send PASV and if the server accepts it proceed, otherwise remain in active mode (and if you are behind a nat or a firewall you are no worse off than you already were). /Marino > Nick > > > Unless I hear unanimous fierce outcry against it, I'm strongly > > considering making FTP_PASSIVE_MODE obsolete by virtue of being the > > default for all tools/libraries which currently examine it. > > FTP_ACTIVE_MODE will be the new flag for toggling the previous > > behavior. > > > > Given the state of the Internet today, I think this is purely a > > sensible change in defaults.
