Remote copy directories and files through an SSH tunnel host

If you have lots of remote hosts sitting "behind" an ssh proxy host, then there is a special-case use of "rsynch" that allows one to easily copy directories and files across the ssh proxy host, without having to do two explicit copies: the '-e' option allows for a replacement "rsh" command. We use this option to specify an "ssh" tunnel command, with the '-A' option that causes authentication agent requests to be forwarded back to the local host. If you have ssh set up correctly, the above command can be done without any passwords being entered.

What others think

This is neat. I'm sure many people (including myself) don't know enough about forwarding credentials and other ssh tricks.

ssh rocks!

Comment by alperyilmaz 291 weeks ago

Hi. I need to encrypt transfers and I am not sure if rsync does encrypt from sshproxy to my pc.

Comment by hectorlara 208 weeks and 5 days ago

@hectorlara, using the ssh tunnel does, in fact encrypt the rsync contents between the end points. Please read "man rsync" for more details, such as using an encrypted tunnel to an rsync daemon.
