Hi,

I finally found some time and tried the following:

* Run an SSH daemon on Windows (I used freeSSHd, http://www.freesshd.com/)
* Backup from a Linux host to the Windows host (launching rdiff-backup on the
Linux box)

After configuring the SSH daemon for public key authentication, and verifying
that the connection worked as expected, I ran rdiff-backup and got the
following output:

cPickle.UnpicklingError: invalid load key, '

Notice that the 'C:\temp\test' directory on the Windows host got created, but
nothing else happened. The SSH connection stayed up until I stopped the SSH
daemon on Windows, after what I got 'Read from remote host 192.168.0.171:
Connection reset by peer' in my Linux shell.

My guess is, that the freeSSHd screws something up here, but I'm not sure.

When the option 'Use new console engine' (in the SSH tab of freeSSHd's
settings dialog) is checked, I don't even get this far:

$ rdiff-backup -v9 temp address@hidden::C:\\temp\\test
Wed Aug  6 13:08:34 2008  Using rdiff-backup version 1.2.0
Wed Aug  6 13:08:34 2008  Executing ssh -C address@hidden rdiff-backup
- --server
Wed Aug  6 13:08:34 2008  Client sending (0): ConnectionRequest: Globals.get
with 1 arguments
Wed Aug  6 13:08:34 2008  Client sending (0): 'version'

... and there rdiff-backup hangs.

Can anyone deduce from rdiff-backup's output what might be wrong with the
connection? I'll try with another SSH daemon next.

I saw ahd71's mail where he describes how to use Plink.exe to backup remotely.
But in this case rdiff-backup must be initiated from the Windows machine. I'd
prefer to initiate rdiff-backup from a Linux machine and store the backups on
the Windows machine though (which requires an SSH daemon on the Windows 
machine).

Patrick.
