[Zope] using python ftplib with zope

9 Jul 2004

      I am having problems using ftp to down load objects from zope using python
ftplib module.
I appear to get authorized ok but then keep getting the message 530
Unauthorized when any ftp command is used.
I can login as the same user using interactive ftp and download the same
object.

Thanks in advance for any advice/help.  Gene Tuttle

here is the debug information:
