Server to Server SCP through the bastion about the-bastion HOT 3 OPEN

Hello,

This is not supported (yet). I checked and it seems that when you type the following command from machine A:

user@A$ scp B:file C:file

This is what happens:

• A connects through ssh to B, and launches the command scp file C:file on B
• B connects through ssh to C, and launches the command scp -t

With a bastion between A and the rest of the infrastructure, this would mean:

• A connects through the bastion to B, and launches the command scp file C:file on B
• B connects directly through ssh to C (no bastion there), and launches the command scp -t

In both cases, this implies that B needs to have direct access to C.

I'll check if this can work with some minor adjustments to the code.

This should be doable, however in the meantime, you should be able to do, if your bastion alias is bssh, instead of:

scp -S ~/scp_bastion server1:file1 server2:file2

Try this:

bssh server1 -- scp file1 server2:file2

It's functionally equivalent, and what happens under the hood if you use scp directly with 2 remote servers.
If you have the chance to test this with your setup, can you confirm it works?

Hi, what I want to do is to download a file from a server behind the bastion, and to upload it to another server also behind the bastion, like what is shown here : https://unix.stackexchange.com/a/184435
