help on transferring files via ssh

[debernardis]

I'm asking your help for doing one thing with my n900 and my home server.

I originate a ssh connection from my n900 to my home server, and execute on the server a terminal application. The application writes one file in a directory on the server.
I would like to be able to transfer that file from the server to my n900 on the same ssh session, i.e the one that is originated from the n900.

I thought of using scp, but as far as I know it means that from the server I should ssh back to the n900 like that: scp user@n900.ip.address:file/path/on/server file/path/on/n900
but it's not what I want, because I should know also the ip address of the n900.

Ideally, I would add the transfer command to my server application so that the file is automatically transferred to my n900 when the program quits.

Is it feasible? How can I do that? Thanks :)

So you want to scp a file from the server that you've SSH'd into back to the N900, right?

Sounds like you've got it right. Just execute:

scp <target file name> user@<n900's IP address>:/path/to/target/directory

What's the problem with doing it like this?

You said: "but it's not what I want, because I should know also the ip address of the n900."

I don't really understand this statement. Are you having a problem because you DON'T know the N900's IP address?

I think this might be a language barrier problem because I can't really understand what you are trying to say.

The IP address should be pretty easy to get (via the SSH_CLIENT environment variable). The alternative would be to use remote tunneling along with another protocol (or just a simple client/server app).

I assume N900 might be behind proxy or NAT, nevertheless scp just need source and target, here is back and forth:
scp user@server:file/path/on/server /file/path/on/n900
scp /file/path/on/n900 user@server:file/path/on/server

p.s. tunneling.... some people really make it look like a rocket science, google for "man scp" maybe? ))

Thanks people, even if English is not my mother tongue, you grasped it right. Putting it simply, I didn't know of the existence of the SSH_CLIENT environment var. This makes the thing quite simpler :)
