I have the following setup: Machines A, B , C running linux. I have to do a continuous rsync from machine A to machine C and have a script for that. However, the access to machine C from machine A is only through B. So I have to ssh into B and then I can ssh into C.
The way to rsync that I have now is that first I rsync from C to B and then rsync from B to A. However, with the additional copy between the machines, this is
You can use netcat for this. Here's an example setup:
On machine A, your ~/.ssh/config looks like this:
Host machinec.whatever.domain.com
ProxyCommand /usr/bin/ssh machineb /usr/bin/nc %h %p
(with any addition of IdentityFile or anything else that you may require)
This will let you rsync straight through machine B; netcat/nc will forward the entire data stream for you. Of course, this requires that nc be available in that path on machine B.
