Cannot ls in FTP from Ubuntu to IIS 6, can from Vista

Question

I have an IIS 6 server running FTP on the standard port with basic authentication.

If I connect from a Vista machine (command line FTP client) that is not on the corporate network, all works well.

If I connect from an Ubuntu machine also not on the corporate network, I can connect but not do anything else:

230 User MyUser logged in. 
Remote system type is Windows_NT.

But then any other commands fail:

ftp> ls
500 Invalid PORT Command.
ftp: bind: Address already in use
ftp>

Any idea what might be causing this?

At the end of the day I'm trying to get Maven to perform a release using FTP to the IIS server. Solving this is a step down that path.

Answer 1

If you want passive ftp with the BSD ftp client in Ubuntu you can do this in two ways:

ftp -p <host>
pftp <host>

Answer 2

What is the configuration by default on Vista active or passive mode? What is it on ubuntu? I guess you have to tell explicitly which one you want to use and it solves your problem.
