Remote copy directories and files through an SSH tunnel host

rsync -avz -e 'ssh -A sshproxy ssh' srcdir remhost:dest/path/
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.

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

@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.

Covid had changed our life to another level. http://meveganrecipes.com I cook, eat more than I work. I get time to spend with my family, doing whatever I kept pending. But the never-ending increase in the number of patients is really worrying.

Thanks for the code you have shared here about the remote copy directories and files through an ssh tunnel host which is a new topic for everyone and everything related to it is very well explained here and hope it is helpful Effect Of CBD
