Copy files across two SSH connections in one go (OS X, GUI or CLI)

Question

Forward SSH traffic through a middle machine.

I'm currently deploying a web app that requires files be copied to an internal server via a public facing server.

My current workflow looks like this:

• scp files to publicserver.example.com
• ssh to publicserver
• scp files to 10.2.68.10

What I'd really like to do is to copy files to the internal server in one go - either using a GUI, or via the command line.

Any ideas?

Use ssh to forward your port and then make scp use that port:

ssh -L yourport:internal.host:hostport [e-mail]

Then:

scp yourfile.xxx localhost:/directory -P yourport

I think that should already do the trick. You might want to take a look at man ssh and man scp if I got the arguments in the wrong way.
