What's this? Is this meaningless output expected? Does this come under
your definition of "ran fine in windows"?

What's this? Is this ...

"No such file or directory" is probably not very meaningful. According
to RFC 959, code 553 means "Requested action not taken. File name not
allowed." This may give you a better clue.

You started off on the right track here, using the os.path module
functions for portability ...

> listname =
> string.join(os.listdir('/usr2/websoftware/oraclebackupfiles/pdsweb'),',')

.. but were quickly seduced by the Dark Side; those hardwired slashes
are harbingers of doom ...

> print listname

Not relevant to your problem, but the above is susceptible to stepwise
refinement:
(1) listname =  string.join(os.listdir(filename),','); print listname
(2) print string.join(os.listdir(filename),',')
(3) print os.listdir(filename) # not identical, but good enough for
debugging

> ftp.login(user='fudd',passwd='elmer',acct='looney')   # user info
> ftp.cwd('/usr2/pdsweb/oraclebackupfiles2/pdsweb/')

Those slashes again ...

Wwwhhhoooooopppsss!!!  A *back*slash ???? This *might* just explain
why it doesn't "run fine" on non-windows.

Try using os.path.split() for portability. When you RTFM and you find
that the FingM refers to "slash" instead of "path separator", you may
take some comfort from the fact that you are not alone in
non-portability :-)

However, try fixing the two following print statements first, and run
this again, so that you can see better what is happening.  Then change
to using os.path.split()

>     print "filename = " + 'filename' + "\n"

This can be "refined" to 
   print "filename = filename\n"
... perhaps not what you intended. Perhaps you are a recent convert
from some  language where " (quote) and ' (apostrophe) have different
meaning. Perhaps you meant to use ` (grave accent) instead of '
(apostrophe). You may like to try repr(x) instead of `x`.
