I'm trying to setup automated backups via cron on a Fedora 13 system,
connecting to a Centos 5.5 server.
When I run the simple script interactively, it works fine, using an
SSH key to connect to the server.
When I schedule the script via cron it fails with the "Invalid SSH
password" error.
Here's the traceback:
Backend error detail: Traceback (most recent call last):
File "/usr/bin/duplicity", line 1239, in<module>
with_tempdir(main)
File "/usr/bin/duplicity", line 1232, in with_tempdir

remlist = globals.backend.list()

line 270, in list
l = self.run_sftp_command(commandline, commands).split('\n')[1:]
File
"/usr/lib64/python2.6/site-packages/duplicity/backends/sshbackend.py",
line 197, in run_sftp_command
raise BackendException("Error running '%s'" % commandline)
I've seen similar errors reported and there's
https://bugs.launchpad.net/duplicity/+bug/411145, though there's no
sign of a "Couldn't get handle" error in my case.
The problem occurs both with the current Fedora package 0.6.08b and
with a local build of the latest version 0.6.09.
Here's the redacted script:
#!/bin/sh
# Script to backup $HOME
export PASSPHRASE="<passphrase>"
duplicity -v 9 --ssh-options="-oIdentityFile=/home/linda/.ssh/id_dsa"
/home/linda scp://linda@<remote server>//home2/linda
