Has anyone here run Duplicity on a ReadyNAS? I'm trying but here's what I get:

duplicity full --encrypt-key="ABC123" /home/jason/ scp://[email protected]//gob
Invalid SSH password
Running 'sftp  -oServerAliveInterval=15 -oServerAliveCountMax=2 [email protected]' failed (attempt #1)

I've also found this post that says the "Invalid SSH password" message doesn't actually mean invalid SSH password. This would make sense because I'm not using an SSH password; I'm using a public key.

I can ssh, ftp, sftp and rsync into my ReadyNAS just fine. (Actually, to be more accurate, I can get past authentication with ssh, ftp and sftp but I can't actually do anything past that. Regardless, that's enough to tell me that "Invalid SSH password" is bogus. Rsync works with no problems.)

The post I found says the command will work as soon as the directory at the end of your scp command exists, but I don't know how to check for that. I know the share gob exists on my ReadyNAS and I know it's writable because I'm writing to it with rsync.

Also, here is the verbose output:

Any ideas as to what's going wrong?
