Problems with FTP

Fri Jan 21 15:24:41 EST 2011

The standard FTP protocol does not supporty any kind of proxy-ing
feature natively.
The only closest thing to the concept of a "proxy" we can find in the
FTP protocol is the site-to-site transfer feature:

...but it's something different.
By taking a look at your code, though, this is out of question anyway
since you can't even connect to the server, let alone send proxy-like
(non-standard) commands.
I'd focus on investigating whether it's something with the internal
network and forget about proxy-related problems since from here I can
connect to indexftp.barcap.com.
As for urllib's proxy option I'd say it's only valid for HTTP protocol.

>> Traceback (most recent call last):
>  File "<pyshell#51>", line 1, in <module>
>    filehandle = urllib.urlopen(some_url, proxies=proxies)
>  File "C:\Python27\lib\urllib.py", line 84, in urlopen
>    return opener.open(url)
>  File "C:\Python27\lib\urllib.py", line 177, in open
>    fullurl = unwrap(toBytes(fullurl))
>  File "C:\Python27\lib\urllib.py", line 1026, in unwrap
>    url = url.strip()
