    Hmmm, I already fail at step 3.

    cp:/backup# FTP_PASSWORD=secred duplicity /path/to/some/folder ftp://[email protected]/
    Traceback (most recent call last):
      File "/usr/bin/duplicity", line 373, in ?

      File "/usr/lib/python2.4/site-packages/duplicity/collections.py", line 406, in set_values
        backend_filename_list = self.backend.list()
      File "/usr/lib/python2.4/site-packages/duplicity/backends.py", line 365, in list
        try: return self.error_wrap('nlst')
      File "/usr/lib/python2.4/site-packages/duplicity/backends.py", line 335, in error_wrap
        except ftplib.all_errors, e: raise BackendException(e)
    duplicity.backends.BackendException: 226 Transfer complete.
    any idea?

    Hi falko

    I added a comment on how to make it work :) it was very simple actually - just you need to know how ;)

    Failure with non-standard ftp port

    i have tried :xxxx after the host name and it is recognized but the :port part is dropped by various ncftp commands so I receive an error from the remote ftp server. I have sarched for alternative methods of specifying the port number but they either fail immediately or eventually drop the port number in the host string sent to the remote server.

    As you can see it drops the port number.

    Any ideas on this problem?

    Several other port attemps fail.

    FTP_PASSWORD=???????? duplicity -v 9 -P 1976 .local/share/evolution ftp://[email protected]/evolution

    duplicity: error: no such option: -P

    port number

    I can do a successful back and restore to a local machine that uses port 22 without using hostname:22. If I use hostname:22 if fails in the same way as using hostname:1976 to my remote server?

    Something is wrong with the documentation?

    It recognizes ":22" as "-P 22" but then the server refuses to respond.

    Try using hostname:22 to the server you backup to and let me know if it works?
