I should note now that I've tinkered around a bit more, that everything works as intended if I use the "-i identity_file" switch when connecting from "Automation" and point that at the private key on the "Automation".

There are three systems involved here.

1) Production

2) Workstation

3) Automation

Numbers 2 and 3 are on the same network, #1 is on a remote network. #3 does not have a monitor attached, it is managed via SSH from #2.

Now #2 has public/private keys available for, and is able to connect to #1 and #3 without a password just fine.

I need to connect to #1 from #3 in the same way. I first tried copying the keys #2 uses for #1 over to #3. I'm prompted for a password when I attempt to connect to #1 from #3. I've used ssh-keygen while logged into #3 and imported those keys to #1 just as I did when setting up #2 to connect to #1. I'm still prompted for a password.

Why am I being prompted for a password when connecting from #3 and not for #2 ?

The only difference I can think of is, when connecting from #3, I'm already remotely logged into #3 from #2.

I'm looking for an alternative to using this, it doesn't have to use FTP, but it should provide the same functionality as the "--mirror" option of wget where it only downloads new and changed files.

wget --mirror --preserve-permissions --directory-prefix=/hdd2/website-backups --exclude-directories=special,stats --ftp-user=user --ftp-password=pass ftp://ftp.domain.com

Currently the above command is how a remote site is being backed up every few days via cron job on a home server. The remote site has moved to a new host with SSH available and I've already got public/private keys setup for SSH. Now I would like to use something a little more secure than wget/ftp for the automated backup, but since this site has a lot of image files most of which will not change, I don't really want to zip up the entire documentRoot and download it every time.

I've got two directories.

/application/inbox
/application/unresponsive

The application looks for *.txt files in the inbox and works with them. Periodically the application will save entries from these files into date-named (2009-07-31) files in the unresponsive folder.

I'd like to setup a cron job which works once a day to move the oldest file from the unresponsive box into the inbox, adding a *.txt extension so it's picked up by the application.
