I am working with a supplier who's just tightened their security. They moved from an anonymous FTP setup to a more secure alternative. The parameters they gave me

Host: blahblah.net
Port: 4421
Path: /mailbox
User: (...)
Password: (...)
Auth SSL: yes
Passive mode: yes

Using ftp -pn blahblah.net 4421 allows me to connect but it hangs. I need to specify the "Auth SSL" option in my command line (and script) but how do I do that?

I read the ftp man page of my host and found nothing. I looked at using sftp instead but it seems that the latter does not use passive mode.

My host info Linux 2.6.18-128.el5 x86_64 GNU/Linux

Which operating system? I would assume *nix, but you never know. –  h0tw1r3 Oct 18 '12 at 20:44

Install ftp-ssl or lftp (there are others) for an FTP client with SSL/TLS support.

looked at using sftp instead but it seems that the latter does not use passive mode.

sftp transfers files over encrypted ssh, where as ftp is a completely different protocol.

I won't pretend to understand the intricacies of FTP vs SFTP. In short, there is no other way but to install software, correct? –  Chris Oct 18 '12 at 21:13
    
@Chris correct. Ubuntu does not install a console ftp client with ssl/tls support by default. –  h0tw1r3 Oct 19 '12 at 14:40
