Hi,

Thanks for quick response! Please have a look at my comments below.

As far as I understood there were some strange things which were not
explained
(http://curl.haxx.se/mail/lib-2006-06/0055.html):
        ...
       strange thing...
       the lib525 tool against a localhost ProFTPD (1.2.10) on debian stable
       also works for me,
       but not to a remote one (legolas: ProFTPD 1.2.10 - debian stable).
       ...

Yes, I mean that it hangs untill connection timeout expires. Here is the
complete output:

No, FTP server is connecting to the client after STOR or RETR is sent.
The problem is that client does not send STOR or RETR after PORT
(as shown in the output above).

I will check your test case for active FTP mode( lib525.c - right ? ) and
inform you about results a bit later.
